Abstract Hard carbons are promising anode materials for sodium‐ion batteries. To meet practical requirements, searching durable and conductive carbon with a stable interface is of great importance. Here, we prepare series vanadium‐modified hard submicrospheres by using hydrothermal carbonization followed high‐temperature pyrolysis. Significantly, the introduction vanadium can facilitate nucleation uniform growth spheres generate abundant V–O–C bonds, thus optimizing reaction kinetic....
With the fast economic development and accelerating urbanization, more skyscrapers made entirely of concrete glass are being constructed. To keep a comfortable indoor environment, massive energy for air conditioning or heating appliances is consumed. A huge amount heat (>30%) gained released through windows. Using smart windows with capability to modulate light an effective way reduce building consumption. Thermochromic hydrogel one potential window materials due its excellent thermal...
The transformation mechanism of PHPA-based temperature-sensitive hydrogels showed the water molecules agglomerated into larger clusters, then light was incident at which resulted in changing to an opaque state.
Abstract The mortality of coronavirus disease 2019 (COVID-19) differs between countries and regions. This study aimed to clarify the clinical characteristics imported second-generation cases in Shaanxi. included 134 COVID-19 Shaanxi outside Wuhan. Clinical data were compared severe non-severe cases. We further profiled dynamic laboratory findings some patients. In total, 34.3% patients cases, 11.2% had complications. As 7 March 2020, 91.8% discharged one patient (0.7%) died. Age, lymphocyte...
Abstract Background The mortality of COVID-19 differs between countries and regions. By now, reports on are largely focused first-generation cases. This study aimed to clarify the clinical characteristics imported second-generation Methods retrospective, multicenter cohort included 134 confirmed cases from 9 cities outside Wuhan. Epidemiological, outcome data were extracted medical records compared severe non-severe We further profiled dynamic laboratory findings some patients. Results 34.3%...
Abstract Photosensitive resins with ultralow viscosity suitable for the silicone‐based elastomers by 3D printing were reported. Based on facile one‐pot strategy which involved photo‐polymerization of hydroxyethyl acrylate (HEA) and sol–gel transition process methyltrimethoxysilane (MTMS), tunable mechanical properties could be obtained adjusting ratio HEA MTMS as needed. Due to physically cross‐linked network formed hydrogen bonds between hydroxyl group polyhydroxypropyl (PHEA) chemically...

High aspect ratios trench are commonly used in shallow isolation (STI) or Gate Poly-silicon structures by dry etching of a silicon substrate. During the process, polymerization residues produced inside trench. These must be removed before next deposition process.
