Recent Progress on the Development of Chemosensors
Chemosensors are the chemical structures which convert chemical stimuli into responsive form that can be easily detected, such as change of colour, fluorescence, and other electronic signal. Recently, chemosensors development for detection and monitoring of gases has been growing interest due to the significant importance in environmental and biological systems. Subsequently, the development of chemosensors for detection of various gases is considered to be a significant goal in science and among the all gases, carbon dioxide (CO2) is a major public concern due to its role in global greenhouse warming with environmental pollution. Moreover, quite critical level of CO2 in the modern agricultural, food, environmental, oil and chemical industries is dangerous for living beings to survive such high concentration levels of CO2. Therefore, rapid and selective detection and monitoring of CO2 in the gaseous as well as in the liquid phases provides an incentive for development of new methods. The coverage of this book chapter is divided into different sections according to the use of different types of molecular backbones and the detection pathways.

Recent Trends and Progress in Corrosion Inhibitors and Electrochemical Evaluation
Science and engineering research studies are currently concentrating on synthesizing, designing, producing, and consuming ecologically benign chemical species to replace harmful chemicals. This is due to the increasing demands of conservation knowledge and strict ecological regulations. Numerous environmentally friendly substitutes produced from natural resources, including biopolymers, plant extracts, chemical pharmaceuticals (drugs), and so on, are now frequently used as inhibitors to replace dangerous corrosion inhibitors. Many compounds have been extensively used. A range of methods, including physisorption, chemisorption, barrier protection, thin-film growth, and electrochemical procedures, will be used to provide corrosion resistance. The various kinds of corrosion inhibitors (CIs), the mechanisms underlying inhibition, and the evaluation procedures have all been covered in-depth. This review provides an overview of the relevant literature in which researchers and scientists used different types of CIs, the effect of CIs on metals, and information about designs and mechanisms used to minimize corrosion in a variety of equipment composed of alloys or metals, along with electrochemical evaluation studies. This review will provide scholars with fresh insights to advance the discipline. 2023 by the authors. -
Recent Trends in Composting of Food Waste
Accumulation of food waste materials, contaminated water, and air is an inevitable end result of the rapid expansion of cities across the world. Resource overconsumption remains never-ending, deteriorating the environment and society. Conventional food waste management practices, such as landfills, dumping, and incineration, are proven to be problematic in terms of inhabitants health risks and environmental contamination. Food waste management with a zero-waste approach is given the utmost priority in the present-day scenario and has become a significant part of our routine life. The avoidance and reduction of food waste are very important parts of waste management, as they have a huge impact on our lives and the environment. The conceivable solution is to valorize the food waste into a usable secondary raw material for its utilization in other industries. Composting is a systematic biological process, recognized as a cost-effective method for food waste management. It generates nutrient-rich manure for plant growth and development. This has offered opportunities for organic wastes, especially food waste, as nutrient sources for agriculture. Though traditional agricultural practices with inorganic fertilizers have helped in gaining high yields of crops, their aftereffects on soil have been dismissive. This has opened up a congenial platform for the use of organic manures like compost and vermicompost, due to their positive effects of enhancing soil quality over inorganic fertilizers. Microbial processes are gaining massive significance due to their realistic and eco-friendly nature, resulting in the recovery of biomolecules from food wastes and fermentation end products, ensuring zero waste. Composting strategies that can act on prominent food wastes such as vegetable market waste, fruit waste, slaughterhouse waste, chicken and fish waste, canteen/hotel waste, and house/residential waste will play a promising role in the recovery of sustainable resources. Finding new ways of reducing food waste disposal problems is a topic that must be of the greatest importance for every government, business, and individual. 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG. -

Recent trends in photocatalytic water splitting using titania based ternary photocatalysts-A review
Hydrogen is considered as an ideal fuel, and its use has several advantages. While several methods are available for producing hydrogen, photocatalytic water splitting using semiconductor-based photocatalysts is one of the better methods. Among the various semiconductors, titania, having many desirable properties, is a widely explored photocatalyst material to fabricate ternary heterojunctions. Preventing the recombination of photoexcited charge carriers, reducing the band gap, and enhancing the migration of charges are steps needed to improve the efficiency of the photocatalysts. Various modifications have been made to the structural and chemical properties of the photocatalysts. While innovative synthetic protocols can bring about the desired changes, incorporating metal oxides and noble metals with varied morphologies into titania leads to multijunction photocatalysts. Structural modifications to titania include incorporation of various nanostructured materials, noble metal nanoparticles, transition metal chalcogenides, polymer materials, semiconductors like g-C3N4, quantum dots, etc. 2022 Hydrogen Energy Publications LLC -
Recent trends in the electrochemical sensors on ?- and calcium channel blockers for hypertension and angina pectoris: A comprehensive review
Stress, ingrained human behaviors, an inactive lifestyle, and poor dietary decisions are the primary causes of hypertension and the related coronary artery disease (CAD), which is also commonly referred to as angina pectoris. Effective high blood pressure (BP) treatment represents a substantial approach to reducing the burden of hypertension-related cardiovascular and renal diseases. A group of drugs known as ?-blockers and calcium channel blockers (CCBs) are frequently used to treat diseases like hypertension (high blood pressure), cardiac arrhythmias and heart failure. For efficient therapeutic use and to reduce potential side effects, ?-blocker concentration monitoring is essential. Chromatographic techniques are employed in a wide range to detect ?-blockers and CCBs without interference, among other analytical methods that have been described. For the detection of ?-blockers and CCBs, electrochemical sensors provide numerous benefits including sensitivity, selectivity, rapidity, and cost-effectiveness. These sensors can help with patient monitoring in clinical settings, ensuring that the prescription ?-blocker dosage is within the therapeutic range. Since ?-blockers are frequently consumed by people, the contamination can be occurred through discharge of wastewater. The presence and measurement of ?-blockers in water samples enables researchers to evaluate potential risks to aquatic life and public health. In this regard, this review addresses recently developed electrochemical (voltammetric) methodologies and measurement protocols for the determination of both ?-blockers and CCBs in pharmaceuticals, biological fluids, and environmental samples. Additionally, this review also provides an overview of the various advanced nanomaterials such as carbon nanotubes, graphene oxide, metal and metal oxide nanoparticles, polymeric structures, zeolite materials, ionic liquids, perovskite semiconductor-based materials, MXenes, Quantum dots, Nano MIPs and various dimensional materials applied to fabricate chemically modified electrodes/electrochemical sensors to determine the ?-blockers and CCBs. Moreover supplied are tables listing the analyte, modified electrode, measurement method, measuring medium pH, linear detection range (LDR), limit of detection (LOD) and sensitivity as they are cited in the original research. Furthermore, important conclusions are made from the published reports in the last decade and some future perspectives are also suggested. 2023 Elsevier B.V. -

Recent trends in the transformative impact of biomass-derived carbon dots in biomedical science
Carbon dots (CDs) have gained significant attention from researchers due to their unique properties, which make them a promising option among nanomaterials for biomedical use. From recent trends, it is confirmed that CDs are the best candidates available among nanomaterials for the treatment of various diseases, including Ulcer, Diabetes, Gout, Wound healing and other syndromes. Semiconductor dots, which dominated in the early days, have been replaced by biomass-derived CDs (BCDs) due to their low toxicity, biocompatibility, and ease of synthesis. Although extensive research has been carried out on the applications of CDs in the biomedical field, the use of biomass as a precursor for CDs in therapeutic and clinical applications remains least explored and has not been systematically reviewed. This review primarily focuses on synthesis strategies, factors influencing the biomedical use of CDs, and recent research in therapeutic and clinical applications. In addition, the earlier trend of employing BCDs in bioimaging, biosensing, and molecular detection is also discussed. By examining the latest research developments, we provide a comprehensive overview of the progress and future prospects of BCDs in healthcare. This exploration highlights not only the potential of these sustainable nanomaterials but also their promise in enabling new breakthroughs in disease treatment. 2025 Elsevier Ltd. -
Recentring Personal Development in Counsellor Education: Integrating Self-compassion, Meaning and Self-care in Training
Personal development (PD) was once the cornerstone of counsellor preparation. However, competency-driven reforms of the late-20th century relegated introspective work to the curricular margins. This chapter argues for a systematic reintegration of PD within counsellor education, contending that self-compassion, meaning in life and holistic self-care are pedagogically indispensable for fostering counselling self-efficacy and sustaining the professional quality of life (ProQOL). After tracing the historical displacement of reflective practice, we differentiate PD from the broader notion of personal growth and technically oriented professional development. Synthesising evidence from counselling, health and educational psychology, we demonstrate that trainees who cultivate self-compassion, meaning-making in life and intentional holistic self-care show greater empathic resonance, lower burnout indicators and more ethical decision-making. The chapter offers concrete strategies such as reflective writing, development labs, mindfulness exercises and scaffolded peer-support structures, which educators can embed within diverse regulatory contexts. By restoring PD to the centre of counsellor training, programmes can prepare practitioners who work competently and congruently, safeguarding client welfare and well-being. 2026 by John Wiley & Sons, Ltd.

Receptivity to Change, Work Motivation, and Teacher Engagement among Secondary School Teachers
The present study investigated the teachers receptivity to change in relation to work motivation and teacher engagement among secondary school teachers in Kerala, India. The study primarily focussed on the newlinedevelopment and validation of the Teachers Receptivity to Change Scale. The way the teachers receive the change is a vital determinant that defines the successful execution of the change. The present study used a mixed-methods sequential explanatory design, which proceeded through three phases. The tool construction, which progressed through five stages namely, item analysis, exploratory factor analysis, confirmatory factor analysis, validity assessment, and test-retest reliability, constituted the newlinefirst phase. The development of the tool started with the generation of a pool of items followed by item analysis. The exploratory factor analysis extracted four factors and the confirmatory factor analysis confirmed the four factors namely individual, organizational, educational, and bridging newlinefactors. The structural equation modelling corroborated that the scale excellently fits in the four-factor correlated model and indexed receptivity to change as the sum of the four factors. The final 28-item Teachers newlineReceptivity to Change Scale showed adequate internal consistency (Cronbach s and#945; = .90) and discriminant validity. The validity assessment indicated a moderate correlation between receptivity to change, work motivation, and teacher engagement. The test re-test reliability analysis (Cronbach s and#945; = .88) confirmed the temporal stability of the scale. In the second phase, a sample of 433 secondary school teachers of Kerala, newlineresponded to the standardised questionnaires namely Teachers Receptivity to Change Scale, Multidimensional Work Motivation Scale, newlineand Engaged Teachers Scale. The study also assessed the influence of demographic characteristics such as gender, type of institution, age, subject taught, and years of experience using the Mann-Whitney U-test, newlineand Kruskal-Wallis test. -
Reclaiming Selfhood: Transfeminine Identity in the Poetry of Justice Ameer and Golden
Despite increased visibility of trans identities in contemporary US discourse, Black transfeminine individuals remain subjected to systemic violence, societal misrecognition, and cultural erasure, exacerbated by the fraught political climate under administrations that alternately advance and restrict transgender rights. This paper explores the transformative potential of Black transfeminine poetry as a site of self-representation and resistance against hegemonic frameworks of gender, race, and identity. Through a close reading of select poems by Justice Ameer and Golden, the analysis highlights how their works challenge cisnormative and patriarchal narratives, reclaim authority over gender representation and illuminate the fluidity of identity as a process of resilience and resistance. Drawing on themes of memory, trauma, community, and agency, this paper situates their poetry as both a critique of systemic marginalisation and a radical act of reimagination. By positioning their works within the broader socio-political context of the United States, the paper underscores how Black transfeminine poetics not only confront societal erasure but also construct spaces of affirmation and liberation. Through these explorations, the paper demonstrates the capacity of poetry to subvert oppressive narratives, assert the multiplicity of identity, and envision transformative possibilities for transfeminine existence. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Reclaiming the Ethical Foundations of Mindfulness: Toward a Dharma-Guided Clinical Paradigm
Mindfulness-based interventions (MBIs) have gained clinical prominence yet often omit the ethical and ontological dimensions central to Buddhist traditions. Building on the public health analysis by Oman (2025) of mindfulness along 14 axes (A1A14), which finds alignment on prevention, stress/mental health, resilience, and multisectoral collaboration but identifies gaps in epidemiologic foundations, multilevel intervention design, cultural/religious adaptation, equity, and attention to the collective attentional environment, we propose a Dharma-guided model that directly addresses these implementation challenges (A6A13). Specifically, we outline: (a) culturally responsive adaptations that preserve ethical integrity; (b) multilevel delivery (individual, group, institution, and community) through stepped-care and community-owned pathways; (c) clinician competencies in intercultural/interreligious literacy; (d) metrics and study designs that build the missing epidemiologic base; and (e) interventions responsive to societys attentional environment. This public health-oriented translation repositions MBIs as vehicles for existential insight, moral development, and culturally grounded healing with population-level relevance, complementing the agenda of Oman (2025) and advancing an implementation-ready framework for diverse settings.

Recognition and Understanding of Emotions in Persons with Mild to Moderate Mental Retardation
Deficits in intellectual ability have been linked to deficits in emotion understanding and consequently social competence. Research suggests that individuals with mental retardation exhibit deficits in their ability to identify emotional states in themselves and others, relative to normal mental age matched controls and peers and display an inability to decode facial expressions of emotion. Emotional experience is elicited in part by a cognitive appraisal of a situation toward a goal. However, the ecological validity of previous studies is limited. In this study we developed new materials to investigate the emotion understanding skills of persons with mild to moderate mental retardation. Six tasks included faces displaying emotion in context, comic strips, audio, video and audio-visual material of individuals expressing emotions in context. Results indicated that the mentally retarded were able to identify emotions in context than expressions without context and emotion understanding improved with increasing contextual cues and dynamic content. 2014, Springer India Pvt.

Recommendation of diet using hybrid collaborative filtering learning methods
These days, various recommender systems exist for online advertisement services which recommend the products considering users interests. Similarly, health recommendation systems are becoming most important component in individuals life. Due to the modernization and busy schedule, people give less concern to their eating patterns. This leads to various health issues like obesity, thyroid disorder, diabetes and others. Every individual has different health issues and food habits. Therefore, diet recommendations should be suggested by considering their personal health profile and food preferences. So, it becomes essential to analyze individuals health concerns before recommending the diet with required nutrient values. Thus, it helps people to minimize the further risks associated with the current health conditions. The proposed diet and exercise recommender framework suggests a balanced diet for thyroid patients. It takes care of the food intake with necessary nutrients requirement based on thyroid disorders. This paper applies K-nearest neighbor collaborative filtering models using various similarity measures. The paper assessed two-hybrid learning methods, KNN with alternating least squares: KNN-ALS and KNN with stochastic gradient decent: KNN-SGD. The experimental setup analyzed and evaluated the performances of all algorithms using mean absolute error (MAE) and root mean squared error (RMSE) values. Springer Nature Singapore Pte Ltd 2020. -
Recommendation of food items for thyroid patients using content-based knn method
Food recommendation system has become a recent topic of research due to increase use of web services. A balanced food intake is significant to maintain individuals physical health. Due to unhealthy eating patterns, it results in various diseases like diabetes, thyroid disorder, and even cancer. The choice of food items with proper nutritional values depends on individuals health conditions and food preferences. Therefore, personalized food recommendations are provided based on personal requirements. People can easily access a huge amount of food details from online sources like healthcare forums, dietitian blogs, and social media websites. Personal food preferences, health conditions, and reviews or ratings of food items are required to recommend diet for thyroid patients. We propose a unified food recommendation framework to identify food items by incorporating various content-based features. The framework uses the domain knowledge to build the private model to analyze unique food characteristics. The proposed recommender model generates diet recommendation list for thyroid patients using food items rating patterns and similarity scores. The experimental setup validated the proposed food recommender system with various evaluation criteria, and the proposed framework provides better results than conventional food recommender systems.
