Abstract: The systematic analysis of edible biochips provides accurate and reproducible data that supports quality assurance, safety assessment, and optimization; for utilization in food and industrial processing applications. Despite their wide deployment, limited studies have comprehensively compared the physicochemical properties of different cassava varieties using standardized analytical methods. This study focuses on the investigation of the species-dependent variations in the physicochemical properties of cassava chips. Game-Changer, Obasanjo-II, Poundable, Hope, and Baba-70 denoted as samples A, B, C, D and E respectively were oven-and-sun dried under controlled conditions. Moisture, cyanide, and physicochemical properties were modeled using Response Surface Methodology (RSM), Principal Component Analysis (PCA), Radar plots and Analysis of Variance (ANOVA) for optimization. The investigation covered percentage composition of fresh and dried samples, vitamins-minerals contents, principal components, correlations matrix, nutrients radar, hydrogen cyanide (HCN) content, moisture content and fundamental chemical attributes affecting the structural integrity of the chips. Sample D exhibited the highest initial moisture content while Sample E recorded the lowest, indicating a species-dependent variation in moisture retention. Minimal cyanide content within acceptable range was achieved, which demonstrates effective detoxification under controlled conditions. Species and temperature exerted a stronger influence than time; and observation identified specie as the most critical factor. PCA revealed complex nutrient trade-offs among minerals and vitamins, while RSM indicated that balanced control of drying time and temperature, rather than extreme settings, ensures optimal moisture reduction and processing efficiency. These findings underscore the hypercritical role of species selection in post-harvest cassava processing and provide baseline data for predicting drying behavior, ensuring product safety, and optimizing processing parameters for food and industrial applications.

Abstract: The atmospheric drying and freezing drying were utilized to prepare graphene aerogels (GAs), and the effect of the different drying methods and the key parameters on their structures and properties were comparatively investigated. Three kinds of GAs were synthesized using different reduction and drying ways. GA1 was prepared by subtly regulating the structure of the hydrogel and using an atmospheric drying, while GA2 and GA3 were prepared using a common reduction and freezing drying method. The results shows that GA1 possesses a uniform pore structure constituted by lamellar interconnected graphene oxide (GO) sheets with little of stacking texture, and it is super elastic and can restore to its original shape even after 90% strain. GA1 also has a high adsorption capacity ranging from 90.47-167.24 times of its own mass and a rapid adsorption efficiency toward organic solvents and in addition it possess excellent recyclability. The comparative study indicated that GA1 far surpasses GA2 and GA3 in performance and structure. The study on the formation mechanisms revealed that the subtly regulated structure of the hydrogel is of key importance to the atmospheric drying, and the capillary force up on this drying can be utilized to adjust its pore structure. It is the firstly attempted to investigate the roles of reduction and drying methods upon preparing GAs, and the results will be of great importance to guide the synthesis, design, structure optimization and performance improvement of GAs.

Abstract: Technostress, a negative psychological state arising from an inability to cope with the demands of information and communication technologies (ICTs), has become a pervasive psychosocial challenge in the digital age. This systematic review synthesizes and critically evaluates the extant literature from 2015 to 2025 to provide a comprehensive analysis of the psychological and social aftermaths of technostress. The findings robustly link specific technostress creators, such as techno-overload, techno-invasion, and techno-uncertainty, to severe psychological consequences, including heightened anxiety, clinical depression, and professional burnout. Socially, technostress erodes relational and professional boundaries, significantly increasing work-family conflict and, paradoxically, fostering social isolation despite the hyper-connected nature of modern life. However, these outcomes are not uniform across populations; they are significantly moderated by demographic factors like age, gender, and socioeconomic status, as well as critical contextual factors such as digital literacy, organizational support cultures, and individual coping mechanisms. The review concludes that effectively mitigating technostress requires a multi-level, systemic approach. This approach must integrate individual coping strategies, organizational policies that proactively protect employee boundaries, and a fundamental shift towards ethical, human-centric technology design. Future research should prioritize longitudinal studies to establish causality, intervention-based research to test mitigation strategies, and explore the evolving nature of technostress in the context of emerging technologies like artificial intelligence and algorithmic management.
