Designing Biomass Rice Husk Silica as an Efficient Catalyst for the Synthesis of Biofuel Additive n-Butyl Levulinate
The conversion of lignocellulosic biomass levulinic acid to biorefinery platform organic component n-butyl levulinate is done by an eco-friendly process. The catalyst used for this reaction was prepared by an innovative strategy of impregnating CeO2 and Sm2O3 on silica derived from rice husk, biomass of low economic value, using different methods. The impregnation of ceria and samaria into the silica framework led to a change in the textural properties which was confirmed by various spectroscopic methods. A comprehensive study of the influence of reaction parameters on the esterification of levulinic acid with n-butanol revealed the optimum conditions for maximum yield and selectivity. In the solvent-free condition, the reaction achieved 94.9% conversion of levulinic acid and 97.2% selectivity of n-butyl levulinate within a duration of 1.5h. The regenerated catalysts were stable and efficient up to four cycles. [Figure not available: see fulltext.]. 2020, Springer Science+Business Media, LLC, part of Springer Nature. -
Role of Sm3+ and Ce4+ on mesoporous rice husk silica for selective oxidation of benzyl alcohol to benzaldehyde
Silica was prepared from rice huskagricultural wasteby soaking and pyrolysis method. Ceria and samaria were impregnated on silica by rotavapor-assisted impregnation method. The physicochemical properties of CeSm/Si catalyst were determined by BET, FT-IR, XRD, SEM, EDX, and n-butylamine titration. Catalytic activity was evaluated by oxidation of benzyl alcohol (Bzl-OH) to benzaldehyde (B-CHO) using H2O2 as an oxidant in acetonitrile medium. Different reaction parameters like time, temperature, solvent, and catalyst amount on the reaction were also studied. Among the various catalysts, 50Ce50Sm/Si showed the impressive catalytic performance with a selectivity of 91.4% to benzaldehyde. The improved catalytic performance was attributed to the well dispersion of ceriasamaria on the surface of silica. These materials can be reused effectively up to four cycles without significant loss in their selectivity. Moreover, excellent selectivity of benzaldehyde in shorter duration using modified rice husk silica catalysts makes this protocol highly attractive and practically beneficial.

Why should businesses care about the metaverse
The fourth wave of computer innovation is now being driven by virtual reality (VR) and augmented reality (AR), two spatial, immersive technologies. The resulting pervasive computing paradigm, which this wave is expected to produce, can change (online) commerce, entertainment, distant employment, and education. This new paradigm is called the Metaverse. Although the metaverse is still in its infancy, history demonstrates how swiftly new technology can advance, potentially leaving those who lag. Digital reality technologies can transform the entertainment industry, remote work, education, marketing, and economics. Additionally, these technologies are starting to create a new paradigm for information exchange. The concept of the Metaverse has given rise to a new paradigm. While it appears that it will take years for the metaverse to reach its full potential, it is currently a phenomenon marked by the activity of hundreds of entrepreneurs who are making noise but producing no noteworthy results. According to many observers, the current uptick in activity by large tech businesses is assisting in bringing some order to the market's volatility by providing startup companies with the dependable mainstream customer bases they lack. In order to provide better and more integrated business processes, metaverse will provide a far more immersive experience to an organization's whole ecosystem of clients, staff, and partners. In light of this, the study's objectives are to comprehend the business prospects in the metaverse, identify relevant business strategies, and forecast future business developments in the metaverse. The study also looks at the challenges that companies have while integrating the metaverse, taking into account different scenarios. 2024, IGI Global. All rights reserved. -

Trait-Driven Persuasion: Investigating the Role of Personality in Shaping Advertising Effectiveness
This study examines how the Big Five personality traits influence consumer responses to different advertising appeals persuasive, rational, emotional, humour, and fear. A descriptive research design with snowball sampling was used to collect data from individuals (n = 120). Standardized self-report questionnaires were administered, including a demographic information form, a Big Five personality measure (assessing extraversion, agreeableness, conscientiousness, neuroticism, and openness), and scales evaluating perceived effectiveness of five advertising appeals; overall internal consistency was acceptable for exploratory research (Cronbachs ? = .65). Correlation analysis and structural equation modelling (SEM) were conducted. Results reveal distinct associations: agreeableness aligns with humour appeal, neuroticism with emotional and fear appeals, conscientiousness with rational and persuasive appeals, extraversion with fear appeal, and openness with humour appeal. These findings contribute to personality-driven marketing research by providing empirical evidence on how individual differences shape advertising effectiveness. The study highlights implications for advertisers seeking to design targeted and psychologically congruent campaigns based on personality segmentation. Advertisers can apply personality-driven segmentation to design psychologically congruent campaigns. 2026, Institute of Applied Psychology, University of the Punjab Quaid-eAzam Campus.

This research highlights the use of a WO3:CeO2@MXene/gC3N4 (MGWC) nanodisk as a versatile material. MGWC demonstrates efficient photocatalytic degradation of moxifloxacin (MOF) in water under sunlight and also shows great promise for high-performance supercapacitor applications. MGWC was synthesized using a modified hydrothermal method and thoroughly characterized using various techniques. The MGWC showed a band gap energy of 2.79eV determined through UVVis DRS analysis and an average crystallite size of 39.6nm calculated from XRD. A promising photocatalytic activity was observed for the degradation of MOF, outperforming other photocatalysts. Additionally, preliminary studies examined variations in catalyst concentration, pH, kinetics, electrolytes, scavengers, reusability, and TOC, contributing valuable insights. Under optimal conditions, the MOF achieved almost complete degradation, reaching about 99.7% within 180min using the MGWC photocatalyst. Additionally, MGWC exhibits promising potential in supercapacitor applications. EIS and CV studies have been used to examine MGWCs exceptional charge transfer properties. CV tests confirm the pseudo-capacitive nature of MGWC electrodes. GCD studies of MGWC exhibit a high specific capacitance of 551 F/g at 1 A/g with incomparable capacitance retention of 98.1% over 10,000 cycles. This research not only aids in reducing emerging environmental pollutants but also sets the stage for sustainable energy solutions.

EShield: An effective detection and mitigation of flooding in DDoS attacks over large scale networks
Distributed Denial-of-Service attacks are very hard to be mitigated in wireless network environment. Here in this manuscript, an effective method of flood detection and mitigation architecture is proposed named eShield, which detects and prevent flooding attacks through spoof detection technique. The proposed method uses an architecture and an algorithm. eShield deals with Intrusion Protection and Detection Systems (IPDS) which collaboratively defend flooding attacks at different points in the network. Here eShield detects the supply node with its port variety which were below assault. Inorder to reduce the burden on international IPDS eShield makes use of distinct nearby IPDS for the assaults in flooding which have been carried out collaboratively. The assessment is done through the widespread simulation of eShield and it is proved to be an actual values based on time delay, false positive rates, computation and communication overhead.

Artificial intelligence for diabetic retinopathy detection: A systematic review
The incidence of diabetic retinopathy (DR) has increased at a rapid pace in recent years all over the world. Diabetic eye illness is identified as one of the most common reasons for vision loss among people. To properly manage DR, there has been immense research and exploration of state-of-the-art methods using artificial intelligence (AI) enabled models. Specifically, AI-empowered models combine multiple machine learning (ML) and deep learning (DL) based algorithms to improve the performance of the developed system architectures that are commercially utilized for the detection of DR disease. However, these models still exhibit several limitations, such as computational complexity, low accuracy in DR stage detection due to class imbalance, more time consumption, and high maintenance cost. To overcome these limits, a more advanced model is required to accurately predict the DR stage in the initial stages. For example, the identification of DR disease in the initial stage helps the ophthalmologist to make an accurate and safe diagnosis, and thereby, eyesight-related issues may be treated more effectively. This study conducted a systematic literature review (SLR) to provide a detailed discussion of the background of diabetic retinopathy, its major causes, challenges faced by ophthalmologists in DR detection, and possible solutions for identifying DR in the initial stage. Also, the SLR provides an in-depth analysis of the existing state-of-the-art techniques and system models used in DR diagnosis based on AI, ML, and recently developed DL-based approaches. Furthermore, this present survey would be helpful for the research community to receive information on the recent approaches used for DR identification along with their significant challenges and limitations. 2024 The Authors -
Genetically modified foods: bibliometric analysis on consumer perception and preference
In this study, we present the bibliometric trends emerging from research outputs on consumer perception and preference for genetically modified (GM) foods and policy prescriptions for enabling the consumption using VOSviewer visualization software. Consumers positive response is largely influenced by the decision of the governments to ban or approve the GM crops cultivation. Similarly, the public support increases when the potential benefits of the technology are well articulated, consumption increases with a price discount, peoples trust on the government and belief in science increases with a positive influence by the media. Europe and the USA are the first region and country, respectively, in terms of the number of active institutions per research output, per-capita GDP publication and citations. We suggest research-, agri-food industries-, and society-oriented policies to be implemented by the stakeholders to ensure the safety of GM foods, encourage consumer-based studies, and increase public awareness toward these food products. 2022 The Author(s).

Spatial and seasonal association study between PM2.5 and related contributing factors in India
Global environmental pollution and rapid climate change have become a serious matter of concern. Remarkable spatial and seasonal variations have been observed due to rapid industrialization, urbanization, different festive occasions, etc. Among all the existing pollutants, the fine airborne particles PM2.5 (with aerodynamic equivalent diameter ?2.5?m) and PM10 (with aerodynamic equivalent diameter ?10?m) are associated with chronic diseases. This leads to carry out the study regarding the varying relationship between PM2.5 and other associated factors so that its concentration level might be under control. Existing literature has explored the geographical association between the pollutants and a few other important factors. To address this problem, the present study aims to explore the wide spatio-temporal relationships between the particulate matter (PM2.5) with the other associated factors (e.g., socio-demographic, meteorological factors, and air pollutants). For this analysis, the geographically weighted regression (GWR) model with different kernels (viz. Gaussian and Bisquare kernels) and the ordinary least squares (OLS) model have been carried out to analyze the same from the perspective of the four major seasons (i.e., autumn, winter, summer, and monsoon) in different districts of India. It may be inferred from the results that the local model (i.e., GWR model with Bisquare kernel) captures the spatial heterogeneity in a better way and their performances have been compared in terms of R2 values (>0.99 in all cases) and corrected Akaike information criterion (AICc) (maximum value -618.69 and minimum value -896.88). It has been revealed that there is a strong negative impact between forest coverage and PM pollution in northern India during the major seasons. The same has been found in Delhi, Haryana, and a few districts of Rajasthan during the 1-year cycle (October 2022September 2023). It has also been found that PM concentration levels become high over the specified period with the temperature drop in Delhi, Uttar Pradesh, etc. Moreover, a strong positive association is visible in PM pollution level with the total population.

Toward sustainable and eco-friendly production of coffee: abatement of wastewater and evaluation of its potential valorization
Abstract: Coffee is one of the most significant beverages consumed worldwide, dating to times immemorial. It plays a pivotal role in several economies owing to its second position in the list of trading commodity, after petroleum. The growing demand for coffee has resulted in a great amount of coffee production and processing and subsequent release of large volumes of wastewater. This wastewater is characterized to have very high chemical oxygen demand and biological oxygen demand with potential to cause environmental pollution thus requiring smart strategies to effectively reduce their load of the wastewater before releasing them into the habitable ambiance. The existing research on coffee wastewater treatment should be critically analyzed for their sustainability and economic viability for them to be commercially used in developing countries for effluent mitigation. This literature review aims to suggest an effective way to treat the wastewater by combining various methods, coupling it with value addition like energy generation. The goal of this review is to provide a direction for future research to integrated treatment with valorization along with a focus on emerging technologies.
