Despite the potential to significantly enhance the economic viability of biomass-based platforms through the selective conversion of glycerol to 1,3-dihydroxyacetone (DHA), a formidable challenge persists in simultaneously achieving high catalytic activity and stability along this reaction pathway. Herein, we have devised a strategic approach to manipulate the interfacial integration within composite catalysts to address the performance trade-off. Through the modulation of the composite process involving a bio-templated porous ZSM-5 zeolite platform (bZ) and an Au/CuZnO catalyst, three distinct interfacial bonding modes were achieved: physical milling, encapsulation by zeolite, and growth on zeolite.

Deployment of large numbers of low capital cost sensors to increase the spatial density of air quality measurements enables applications that build on mapping air at neighborhood scales. Effective deployment requires not only low capital costs for observations but also a simultaneous reduction in labor costs. The Berkeley Environmental Air Quality and CO Network (BEACON) is a sensor network measuring O, CO, NO, and NO, particulate matter (PM), and CO at dozens of locations in cities where it is deployed.

The escalating global fecal waste and rising CO levels present dual significant environmental challenges, further intensified by urbanization. Traditional fecal waste management methods are insufficient, particularly in addressing the related health risks and environmental threats. This study explores the synthesis of biochar from pig manure as a carbon substrate to disperse and stabilize Cu nanoparticles, resulting in the formation of an efficient Cu-NB-2000 electrocatalyst for electrocatalytic CO reduction (ECR).

Solid organ transplant (SOT) recipients are at increased risk of infective diarrheas. In such patients, diarrhea can be complicated by dehydration, leading to acute kidney injury or vascular thrombosis. Viral diarrhea in SOT is reported to be commonly due to cytomegalovirus and norovirus.

The mode of energy transfer between photosensitizers and oxygen determines the yield of singlet oxygen (O), crucial for photodynamic therapy (PDT). However, the aggregation of photosensitizers promotes electron transfer while inhibiting pure energy transfer, resulting in the generation of the hypotoxic superoxide anion (O) and consumption of substantial oxygen. Herein, we achieve the reduction of the aggregation of photosensitizers to inhibit electron transfer through classical chemical crosslinking, thereby boosting the production of O.
