Benzimidazolium quaternary ammonium salts: synthesis, single crystal and Hirshfeld surface exploration supported by theoretical analysis Owing to the broad applications of quaternary ammonium salts (QAS), we present the synthesis of benzimidazolium-based analogues with variation in the alkyl and alkoxy group at N-1 and N-3 positions. All the compounds were characterized by spectroscopic techniques and found stable to air and moisture both in the solid and solution state. Moreover, molecular structures were established through single-crystal X-ray diffraction studies. The crystal packing of the compounds was stabilized by numerous intermolecular interactions explored by Hirshfeld surface analysis. The enrichment ratio was calculated for the pairs of chemical species to acquire the highest propensity to form contacts. Void analysis was carried out to check the mechanical response of the compounds. Furthermore, theoretical investigations were also performed to explore the optoelectronic properties of compounds. Natural population analysis (NPA) has been conducted to evaluate the distribution of charges on the synthesized compounds, whereas high band gaps of the synthesized compounds by frontier molecular orbital (FMO) analysis indicated their stability. Nonlinear optical (NLO) analysis revealed that the synthesized QAS demonstrates significantly improved NLO behaviour than the standard urea.

Investigating the Routes to Produce Cellulose Fibers from Agro-Waste: An Upcycling Process The agriculture and agri-food sectors produce substantial amounts of plant-based waste. This waste presents an identifiable research opportunity to develop methods for effectively eliminating and managing it in order to promote zero-waste and circular economies. Plant-based waste and by-products are acknowledged as valuable sources of bioactive compounds, including cellulose fibers. Direct application of these fibers in non-food sectors such as textiles can reduce the environmental impact of secondary raw materials. This review aims to provide an overview of novel concepts and modern technologies for efficiently utilizing plant-based waste and by-products from the agricultural and agro-industrial sectors to extract fibers for a variety of final applications, including the fashion industry. Two major routes are identified to produce cellulose fibers: the extraction and purification of natural cellulose fibers and the extraction and purification of cellulose pulp that is further processed into manmade cellulosic fibers. Scalability of experimental results at the laboratory or pilot level is a major barrier, so it is critical to develop closed-loop processes, apply standardization protocols, and conduct life cycle assessments and techno-economic analyses to facilitate large-scale implementation.

Green-synthesis of silver nanoparticles AgNPs from Podocarpus macrophyllus for targeting GBM and LGG brain cancers via NOTCH2 gene interactions Brain tumors, particularly Glioblastoma Multiforme (GBM) and Low-Grade Gliomas (LGG), present significant clinical challenges due to their aggressive nature and resistance to conventional treatments. Traditional therapies such as surgery, chemotherapy, and radiation are often limited in efficacy, necessitating novel therapeutic strategies. Nanotechnology, particularly the use of silver nanoparticles (Ag NPs), offers a targeted and potentially more effective approach. This study focuses on the green synthesis of Ag NPs using Podocarpus macrophyllus leaf extract as a reducing agent. The synthesized Ag NPs were characterized for their physicochemical properties, demonstrating a controlled particle size of 13 nm as determined by scanning electron microscopy (SEM). Fourier-transform infrared (FTIR) spectroscopy confirmed the presence of functional groups, and energy-dispersive X-ray (EDX) spectroscopy revealed that silver constituted approximately 90% of the nanoparticle composition. The Ag NPs exhibited promising biological activity, including 90% free radical scavenging (antioxidant) activity, 99.15% inhibition of protein denaturation (anti-inflammatory activity), and 90.56% inhibition of alpha-amylase (anti-diabetic activity). Additionally, the nanoparticles displayed significant anti-hemolytic (89.9% inhibition) and antimicrobial activities, with a 20 mm inhibition zone against Staphylococcus species. Computational analyses further indicated that the NOTCH2 gene, which is upregulated in LGG and GBM, may interact with Ag NPs, suggesting their potential in brain cancer therapy. The green synthesis approach offers a sustainable and bioactive method for producing Ag NPs, underscoring their therapeutic promise for treating GBM and LGG.

Energy saving potential of advanced dual-band electrochromic smart windows for office integration • New spectrally selective glazing offers optimized comfort and show superior performance in various European climate zones. • Dual-band electrochromic smart windows enhance office energy efficiency by up to 27%. • Electrochromic smart windows cut visual discomfort levels by 32% compared to static glazing. • Intelligent control strategies reduce annual energy use for heating, cooling and lighting. Integrating dynamic transparent technologies into building envelopes is becoming crucial for tackling the challenges posed by climate change, improving energy efficiency, and enhancing occupant comfort. Nowadays, a range of dynamic glazing technologies exists, among which electrochromic glazing is notably effective in contributing to sustainability objectives in building design. This paper presents a comprehensive simulation analysis of the energy efficiency and interior comfort impacts of a novel class of spectrally selective dual-band electrochromic windows, also referred to as “Plasmochromic”. A simplified office model, oriented both south and west, was used to compare the performance of dual-band electrochromic glazing, using experimental data collected from a window-scale prototype, with that of commercially available advanced glazing systems. The comparison was conducted under two different control strategies: a rule-based and a model-based control algorithm. Five European climate zones have been considered to cover most of the continent’s climatic conditions and provide a comprehensive evaluation of the glazing performances. The simulations demonstrate the superior capability of dual-band electrochromic windows, when coupled with an intelligent control strategy, in reducing total annual energy consumption for heating, cooling, and lighting by up to 27% compared to the best-performing static solar control glazing systems. Additionally, they achieve a reduction of up to 32% in visual discomfort, measured by the cumulative value of useful daylight illuminance.

Sustainable composites with self‐healing capability: Epoxidized natural rubber and cellulose propionate reinforced with cellulose fibers Abstract Aligned with the UN's Sustainable Development Goals (SDGs), self‐healing elastomers stand out as a cutting‐edge field in Rubber Science and Technology. These materials have the potential to reduce resource consumption, prolong the lifespan of infrastructure and products, and contribute to the Circular Economy. This study presents the development of bio‐based self‐healing elastomeric composites prepared from blends of epoxidized natural rubber (ENR) and cellulose propionate (CP) reinforced with cellulose fibers (CFs). The ENR/CP ratio was optimized, with a 70/30 ratio enhancing the tensile strength (TS) of the base rubber and slightly reducing the elongation at break. This blend demonstrated a TS healing efficiency of 75% after a temperature‐driven healing protocol (200 bar at 150°C during 12 h). Then, the CF content was varied to enhance both mechanical performance and self‐healing capabilities. Remarkably, from medium‐high (5 phr to 15 phr) CF content, healing efficiencies higher than 85% were observed with important improvements in the mechanical performance. The self‐healing process was attributed to the synergistic interplay between the polymeric chain mobility and the formation of hydrogen bonds. This innovative approach promises materials with extended lifespans, mechanical robustness, and repairability, underscoring the commitment to SDGs 9, 11, 12, 13, 14, and 15. Highlights Matrix of epoxidized natural rubber (ENR) and cellulose propionate (CP) blends. Cellulose fibers (CFs) reinforced the ENR/CP 70/30 optimized blend. CF addition increases tensile strength (TS) by up to 60%. Healing efficiency over 85% achieved with 5 phr to 15 phr CFs content.
