Silicon Nanocrystals
In article number 2303464, Dongzhi Chen and co‐workers report a hydrophilic, liquid‐phase dispersed, undoped silicon nanocrystals (UA‐SiNCs) simultaneously exhibiting stable photoluminescence and long‐lived phosphorescence at room temperature. Silicon core and surface groups of the UA‐SiNCs play a crucial role in the multiple‐modal emissions, which are advantageous to future advanced...
Silicon nanocrystals (SiNCs) have attracted extensive attention in many advanced applications due to silicon's high natural abundance, low toxicity, and impressive optical properties. However, these applications are mainly focused on fluorescent SiNCs, little attention is paid to SiNCs with room‐temperature phosphorescence (RTP) and their relative applications, especially water‐dispersed ones. Herein,...
Ligand‐Free PtAg Nanoalloys
In article number 2206772, Indranath Chakraborty and co‐workers use the atomic pair‐distribution function combined with powder X‐ray diffraction and transmission electron microscopy for structural analysis of ligand‐free PtAg nanoclusters (NCs). They further investigate the intrinsic enzyme‐mimicking properties of these ligand‐free NCs and explored the mechanistic details...
Nanozymes are nanomaterials with biocatalytic properties under physiological conditions and are one class of artificial enzymes to overcome the high cost and low stability of natural enzymes. However, surface ligands on nanomaterials will decrease the catalytic activity of the nanozymes by blocking the active sites. To address this limitation, ligand‐free PtAg nanoclusters (NCs) are synthesized and...
Structural design of the solar‐absorbing layer has been considered as one of the most direct and effective approaches for improving the solar steam generation performance by maximizing the absorption of sunlight, but great challenges in manipulation simplification and structure controllability still remain. Herein, a polyester (PET) fabric covered with a vertically aligned 3D tower‐like ferrosoferric...
Herein, a type of Fe, N‐codoped carbon electrocatalyst (FeNx/C, Fe‐N‐BCNT#BP) containing bamboo carbon nanotubes and displaying bifunctional high catalytic efficiency for both oxygen reduction reaction (ORR) and carbon dioxide reduction reaction (CO2RR) is reported. It shows high electrocatalytic activity and stability for both the ORR process with onset potential of 1.03 VRHE in alkaline and the...
