LR characterization of chirotopes of finite planar families of pairwise disjoint convex bodies
, 2014 We extend the classical LR characterization of chirotopes of finite planar families of points to chirotopes of finite planar families of pairwise disjoint convex bodies: a map \c{hi} on the set of 3-subsets of a finite set I is a chirotope of finite ...

Advanced Materials, EarlyView.In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

油酸直接马来酸化制备C22 -三元羧酸Preparation of C22-tricarboxylic acid by Maleinisation of oleic acid
Zhongguo youzhi, 2023 为解决C22-三元羧酸合成过程中均相催化剂残留、原料价格较高等问题，以油酸为原料，在路易斯酸催化下与马来酸酐进行Alder-ene加成反应，水解后得到C22-三元羧酸。对C22-三元羧酸的合成条件进行优化并对产物进行了鉴定；制备C22-三元酸钠表面活性剂并研究其表面性能。结果表明：C22-三元羧酸合成的最佳条件为以FePO4为催化剂、催化剂用量3%（以油酸物质的量计）、马来酸酐与油酸物质的量比3∶ 1、反应温度180 ℃、反应时间10 h，在此条件下C22-三元羧酸产率达到78%，油酸转化率为77.4%；

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Hydrodynamics of Sakai-Sugimoto model in the quenched approximation
, 2006 We study transport properties of the finite temperature Sakai-Sugimoto model. The model represents a holographic dual to 4+1 dimensional supersymmetric SU(N_c) gauge theory compactified on a circle with anti-periodic boundary conditions for fermions ...

Bond length of perchlorate at different temperatures: X-ray and neutron comparison. [PDF]
, 2020 The averages (average deviations from the mean are given in square brackets) of uncorrected Cl-O bond distances in a perchlorate anion from an X-ray diffraction analysis of (N-{2-[bis(pyridin-2-ylmethyl)amino]ethyl}pyridine-2-carboxamidato)(nitric oxide ...

Advanced Materials Interfaces, EarlyView.Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...
