Abstract Surface strain engineering is a promising strategy to design various electrocatalysts for sustainable energy storage and conversion. However, achieving the multifunctional activity of catalyst via adjustment remains major challenge. Herein, an excellent trifunctional electrocatalyst (Ru/RuO 2 @NCS) prepared by anchoring lattice mismatch strained core/shell Ru/RuO nanocrystals on nitrogen‐doped carbon nanosheets. Core/shell with ~5 atomic layers RuO shells eliminate ligand effect...
Double hydrophilic block copolymers PEG-b-PEI-linear with different PEI lengths have been examined for CaCO3 mineralization at the air/water interface. The results demonstrated that either length or solution acidity had a significant influence on morphogenesis of vaterite crystals A possible mechanism stratification has proposed. Increasing initial pH value will decrease density PEG anchored binding interface and result in exposing more space as to favoring subnucleation growth polymer−CaCO3...
Mineralization and crystallization of barium carbonate mesocrystals with various shapes complex form using double hydrophilic block copolymers (DHBCs) as crystal growth modifiers in a mixed solvent composed N,N-dimethylformamide (DMF) deionized water (DIW) have been systematically investigated. The effects polymer concentration, solvent, the volume ratio on controlled BaCO3 examined. Shuttle-like rods different sizes ratios average length (L) to maximum diameter (D) can be obtained by simply...
High-quality cobalt-doped ceria nanostructures with triangular column, slab, and disklike shapes are synthesized by tuning the doping amount of cobalt nitrate in a facile hydrothermal reaction. The nanodisks display significantly enhanced catalytic activity CO oxidation due to exposed highly active crystal planes presence numerous surface defects. Detailed facts importance specialist readers published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset....
Alles unter Kontrolle: In Gegenwart des künstlichen doppelt-hydrophilen Blockcopolymers Polyethylenglycol-b-poly(L-glutaminsäure) kristallisieren aus einer Mischung von N,N-Dimethylformamid und Wasser hoch monodisperse Vaterit-Mikrokügelchen (siehe Bild). Änderungen Lösungsmittelverhältnisses beeinflussen die Morphologie der CaCO3-Kristalle.
In this report, a class of homogeneous core/shell Bi2WO6 spheres was successfully synthesized via mild solvothermal reaction processes in the presence Polyvinylpyrrolidone (PVP). Moreover, as-prepared structure can combine with noble metals such as Au and/or Pt light-reduction process to form their composite spheres. The obtained Bi2WO6-based samples were characterized by X-ray powder diffraction (XRD), scan electron microscopy (SEM), transmission (TEM), photoelectron spectroscopy (XPS),...
Superconducting transition edge sensors (TES) based on a Ti microbridge Si substrate have demonstrated very low noise equivalent power. Their effective response time, however, is in the order of microseconds due to relatively high temperature (i.e., 300-400 mK) microbridge, making it difficult read out signal large TES array with SQUID-based multiplexer. We propose twin-slot antenna coupled superconducting separated from feed and supported by free-standing membrane. Its resistive (R-T)...
Terahertz band, which is roughly defined as 0.1 THz to 10 THz, an interesting frequency region of the electromagnetic spectrum be fully explored in astronomy. observations play key roles astrophysics and cosmology. High sensitive heterodyne direct detectors are main tools for detection molecular spectral lines fine atomic structure lines, very important tracers probing physical chemical properties dynamic processes objects such star planetary systems.

In this paper we study the effect of NbN-Au contact pads on performance a superconducting NbN hot electron bolometer (HEB) mixer. The receiver noise temperature (Trec) and IF bandwidth (BN) at LO frequency 1.3 THz are measured different bath temperatures between 3.3 K 8.5 K. Trec BN HEB mixer nearly constant for Tbath/Tc less than 0.7, increase quickly with further Tbath. Measurement results demonstrate that in state have no influence Bn, but resistive make Tbath, indicated by slope change...
