The Haber–Bosch (HB) process has provided most of commercial ammonia at the expense high energy consumption and CO2 emission. Nitrate electroreduction is showing great potential as an alternative route for green scale-up synthesis ambient conditions. However, performance lagged due to lack efficient electrocatalysts. In this work, we present facile uniform Cu nanodisks with exposed (111) facets highly active electrocatalyst electrochemical synthesis, delivering a yield 2.16 mg mg–1cat h–1...
The electrocatalytic nitrate conversion of ammonia at ambient conditions provides not only a solution for restoring the imbalance in global nitrogen cycle but also sustainable alternative Haber-Bosch process. However, large-scale and efficient application denitrification has been limited by lack active catalysts with high selectivity reduction to N2. In this work, we present one-step processed synthetic strategy low temperature prepare carbon-nanobelts-supported uniform Cu Pd nanoclusters....
Abstract An in situ coupling approach is used to fabricate the porous carbon liquid with permanent porosity by directly dispersing hollow nanospheres polymerized ionic liquids. It a kind of homogenous and stable type III at room temperature. Because well‐preserved porosity, this unique capable absorbing largest quantity dioxide than reference PILs solid liquid, thus, can function as promising candidate for application gas storage. More importantly, not only provides an easy method tune...
The stator clamping plate is an important component of hydrogenerators used to fasten the end core. Due complex leakage electromagnetic field in region, eddy-current loss usually very large, which will lead partial overheat. Evaluation losses plates and reasonable structure design are premise ensuring safe stable operation a large hydrogenerator. A 278-MVA hydrogenerator taken as example this paper, calculation model 3-D transient region established validated by temperature test value. Then,...
In order to study the similarities and differences of physical-chemical properties collagens from different parts fish body, acid-soluble pepsin-soluble were isolated skin, scale, bone grass carp (Ctenopharyngodon idellus), with yields ranging 0.7 25.5% on basis dry weight. The content collagen in skin scale was much higher than that according data extraction yield. Collagens have similar amino acid composition, protein patterns, sequences primary structure. Thermal transition temperatures...
Large double-canned induction motor has high power density and usually works in a closed environment. Compared with common motor, there are many contacted metallic parts the stator end region of large which eddy current will exist not only themselves but also between parts. Evaluation eddy-current losses reasonable structure design is premise ensuring safe stable operation motor. A 5-MW-scale taken as an example this paper, 3-D field finite-element calculation model its established solved....
The canned induction motors are widely used in pharmaceutical, chemical, and nuclear fields. It is necessary to calculate the losses, particularly can accurately. Combining steady-state ac magnetic 2-D finite-element solutions with harmonic loss formulas derived this paper, losses under rated voltage various operating conditions obtained. Then, calculation results voltages no-load condition compared experiment data, which provides basis for further performance analysis motor design.

Eu2+,Pb2+-doped core–shell-structured CaS@CaZnOS phosphors were synthesized by a two-step high-temperature solid-phase method. The as-synthesized CaS:Eu2+,Pb2+@CaZnOS:Pb2+ possess excellent dual-excitation and dual-emission (DE2) luminescent properties, which give rise to red emission peaking at 650 nm under green excitation, derived from the core CaS:Eu2+,Pb2+, blue 424 nm, originating shell CaZnOS:Pb2+, ultraviolet (UV) excitation. In addition, tunable red/blue can be achieved changing...
Large-capacity synchronous condenser (SC) is an essential dynamic reactive power compensation device in Ultra-high voltage direct current (UHVDC) transmission system. The particular transient operating state and structural characteristic of SC lead to a severe magnetic saturation effect during operation. To accurately describe the characteristics SC, it urgent establish mathematical model considering effect. Therefore, this paper proposes nonlinear for based on time-varying reactance...
Grape pomace (GP), a by-product in wine production, is nutritious and can be used as feed ingredient for ruminants; however, its role shaping sheep gastrointestinal tract (GIT) microbiota unclear. We conducted controlled trial using randomized block design with 10 Tan lambs fed control diet (CD) pelleted containing 8% GP (dry matter basis) 46 days.
