In addition to the traditional uses of plywood, such as furniture and construction, it is also widely used in areas that benefit from its special combination of strength and lightness, particularly as a construction material for the production of finishing elements of campervans and yachts. In light of the current need to reduce emissions of climate-damaging gases such as CO, the use of lightweight construction materials is very important. In recent years, hybrid structures made of carbon fibre-reinforced plastics (CFRPs) and metals have attracted much attention in many industries.

Polymers are often insulators, but this not a universal intrinsic characteristic of all polymers. For this work, the adhesives used, epoxy and polyurethane, do demonstrate this insulating characteristic. However, there has been significant interest in the development of conductive polymers, specifically adhesives, because of the potential properties and ease of processing of these polymers.

Rational design of carbon material structures is essential for enhancing the performance of persulfate-based advanced oxidation processes (PS-AOPs) in water purification. In this study, a self-doping and self-templating strategy was devised to produce N, S co-doped biochar catalysts through pre-cryocrushing and carbonization procedures employing chitosan (N-source) and lignosulfonate (S-source) derived from biomass waste. The as-synthesized materials exhibited excellent performance in removing tetracycline (TC) through a synergistic process of adsorption and catalytic activation.

Article Synopsis
- The catalytic reduction of p-nitrophenol (4-NP) to p-aminophenol (4-AP) is essential in the pharmaceutical and agrochemical sectors, with sustainable methods being a priority.
- Using manganese dioxide (MnO) supported silver (Ag) nanoparticles (NPs) as a catalyst for the catalytic transfer hydrogenation (CTH) of 4-NP with formaldehyde (HCHO) provides a safer and more efficient alternative due to lower toxicity and easy handling.
- The study shows that electron transfer from Ag to MnO enhances HCHO activation, resulting in a more effective CTH process, with the optimized 15% Ag/MnO catalyst achieving a significant turnover frequency of 3.83
Reconstructing the environmental impact of mining on mountain lakes.

Mountain lakes are particularly fragile ecosystems undergoing important ecological and depositional transformations associated with ongoing global change. However, the history of anthropogenic impacts on mountain lakes and their catchments is much longer, in many cases featuring millennia of summer pastoral farming. More recently, the growing demand for raw materials and energy linked to industrialization, particularly accelerated since the 19th century CE, meant a further increase in human impact on mountain areas.
