Abstract:
... During the landfill gas (LFG) upgrading process of carbon dioxide (CO2) separation by pressure swing adsorption (PSA), if the non-harmful volatile organic compounds (VOCs) are not removed completely, they would cause a rapid failure of the adsorbents due to irreversible adsorption. This point was not given enough concern previously, and no special procedures were generally adopted for VOC removing ...

Abstract:
... Bandgap engineering of photocatalysts is a common approach to achieving high effective utilization of solar resource. However, the difficulty in achieving bandgap narrowing and high activity simultaneously seems to be irreconcilable via the traditional modification pathway. Herein, we have substituted iodine for a fraction of bromine atoms in BiOBr to overcome this restriction and provided some de ...

Abstract:
... Yeast is a widely used recombinant protein expression system. We expanded its utility by engineering the yeast Pichia pastoris to secrete human glycoproteins with fully complex terminally sialylated N-glycans. After the knockout of four genes to eliminate yeast-specific glycosylation, we introduced 14 heterologous genes, allowing us to replicate the sequential steps of human glycosylation. The rep ...
