Solid Oxide Fuel Cells (SOFCs) can convert chemical energy into electrical energy, with high conversion rate, safe operation, no pollutant emissions, and is one of the most potential new power generation devices in future. However, at low medium temperature (below 800℃), cathode impedance SOFCs will increase sharply, resulting adverse effects on cell performance. Finding materials that work key...

Rapid densification of ceramics has been realized and its merits were demonstrated through multiple approaches out which UHS flash sintering attract recent attention. So far, however, scalability remains difficult. A rise in throughput is enabled by the introduction blacklight powered novel light source technology. Intense illumination with photon energy above bandgap (blacklight) allows high a...

Abstract The crystal structures and formation reactions of lanthanum hydride selenides were studied by neutron diffraction on the deuterides. reaction La 2 D 2− x Se with deuterium gas (298 K≤ T ≤567 K, 0.1 MPa≤ p (D )≤9.0 MPa) was followed in situ a sapphire single‐crystal gas‐pressure cell time resolution two minutes. phase fractions Se, 3 4 determined Rietveld refinement. With stepwise incre...

We report the facile and efficient synthesis of common electrophilic haloboranes via a protonolysis reaction between Piers’ borane, HB(C6F5)2, H−X (X=Cl, Br). This route benefits from fast times, easy setup, minimal workup to yield analytically pure etherates, (C6F5)2BCl(OEt2) (1) (C6F5)2BBr(OEt2) (2), as well ether-free tri-coordinate species, (C6F5)2BBr (3).

high molecular weight (hmw) glutenin sub-units and baking quality related traits were studied in 49 iranian wheat landraces. the protein content ranged from 11.2% to 13.55%, and sds sedimentation volume varied between 40 and 60 milliliters. high molecular weight glutenin electrophoresis profiles revealed that at the glu-a1 locus, the frequency of null allele was higher than sub-units 1 and 2*. ...
