Structural basis of haptoglobin-haemoglobin scavenging by CD163 by Zhou, X

“…Indeed, biophysical assays show that calcium ions are critical for ligand binding. Mutational studies demonstrate that while monomeric CD163 can scavenge the multimeric Hp(2-2)Hb, uptake of the dimeric Hp(1-1)Hb and Hb is impaired compared to the wild-type receptor, suggesting that receptor multimerisation evolved to facilitate uptake of lower affinity ligands. …”

Core – shell CuPd@Pd tetrahedra with concave structures and Pd-enriched surface boost formic acid oxidation by Chen, Yifan, Yang, Yifan, Fu, Gengtao, Xu, Lin, Sun, Dongmei, Lee, Jong-Min, Tang, Yawen

“…It is demonstrated that L-proline plays a vital role as a structure-directing agent in tuning the nucleation and growth of concave CuPd@Pd tetrahedra because of the strong coordination abilities of C[double bond, length as m-dash]O, O–H and N–H groups with metal ions. This bimetallic concave structure can endow the nanocrystals with abundant catalytically active sites and fascinating electronic effects, which are suggested to be favorable for electrocatalysis. …”

Efficient nitrate synthesis via ambient nitrogen oxidation with Ru-doped TiO₂/RuO₂ electrocatalysts by Kuang, Min, Wang, Yu, Fang, Wei, Tan, Huiteng, Chen, Mengxin, Yao, Jiandong, Liu, Chuntai, Xu, Jianwei, Zhou, Kun, Yan, Qingyu

“…Remarkably doping Ru into the TiO2 lattice can induce an upshift of the d-band center of the Ru site, resulting in enhanced activity for accelerating electrochemical conversion of inert N2 to active NO*. Overdoping of Ru ions will lead to the formation of additional RuO2 on the TiO2 surface, which provides oxygen evolution reaction (OER) active sites for promoting the redox transformation of the NO* intermediate to nitrate. …”

Mussel-inspired approach to cross-linked functional 3D nanofibrous aerogels for energy-efficient filtration of ultrafine airborne particles by Zhang, Youfang, Zeng, Zhihui, Ma, Daphne Xiu Yun, Zhao, Chenyang, Ang, Jia Ming, Ng, Bing Feng, Wan, Man Pun, Wong, Shing-Chung, Wang, Zhe, Lu, Xuehong

“…Herein, inspired by mussel glue, cross-linked threedimensional (3D) polyacrylonitrile (PAN) nanofibrous aerogels (NFAs) with ultrahigh porosity, hierarchical porous structures, and good compression resistance are successfully fabricated via electrospinning, facile polydopamine (PDA) coating and crosslinking by ferric ions (Fe3+) followed by freeze-drying. Morphology characterization andcompression tests showthatboth multiplehydrogen bondingfacilitated bythePDA coating and Fe3+-PDA coordination bonding could effectively induce the formation of inter-fiber junctions, enhancing compression resistanceofthe3DNFAsandleadingtohierarchical porousstructureswithaverywidePSD.When a thin layer of the optimized 3D NFA with a large specific surface area (85.7m2g−1) is combined with a commercial air filter, the composite filter obtained exhibits high filtration efficiencies of 99.72% and 99.85% for airborne particles with sizes of<100nm and<500nm, respectively, at a low pressure drop of only 54.1Pa. …”
