Abstract Because of their good performance in diffusion‐limited processes, ordered macro‐microporous single‐crystalline metal‐organic frameworks (MOFs) have potential for use various fields. However, there are still very few reports the synthesis such MOFs. A general methodology MOFs is highly desired. Here, a novel strategy reported synthesizing by monodentate‐ligand‐induced situ crystallization within 3D hard template double‐solvent system. space‐confined growth model proposed to clarify...
The development of highly efficient and cheap catalysts for the release hydrogen from chemical hydrogen-storage materials is indispensable coming clean energy economy.
<title>Abstract</title> This study investigates the effects of biochar, phosphogypsum, and calcium superphosphate on composting tomato straw to improve compost quality reduce time. Four treatments were tested: T1 (tomato + 0.5% EM bacterial agent), T2 10% biochar EM), T3 T4 phosphogypsum EM). Results showed that these additives extended high-temperature phase improved maturity, with being most effective. exhibited highest increase in humic acid (127.01%) greatest degradation organic matter...
Exploitation of high-efficiency and low-cost catalysts for dehydrogenation the ideal hydrogen storage material (ammonia borane) can effectively promote development economy. Here, we report an efficient economical non-noble-metal magnetic catalyst (Ni0.23Co0.19P0.58@NHPC900) with nanoparticles uniformly distributed on MOF-derived (metal-organic framework) nitrogen-doped hierarchical porous carbon (NHPC900) by a one-step in situ synthesis method. The has achieved superior initial total...
(Na1-xKx)0.5Bi0.5TiO3 (NBT-KBT-100 x) thin films were deposited on Pt/Ti/SiO2/Si(100) by metal organic decomposition, and the effects of potassium content (x = 0.15, 0.18, 0.20, 0.25) ferroelectric, piezoelectric, dielectric properties films, temperature dependence permittivity NBT-KBT-18 film investigated in detail. is largest effective piezoelectric coefficient d33eff, remnant polarization 2Pr, spontaneous 2 Ps, constant ɛr, lowest loss among films. The constants decrease steeply with...
The imprint of a ferroelectric thin film capacitor is studied using an improved model consisting two nonswitching interface layers near the top and bottom electrodes. difference in electrical conductivity between induces voltage offset deformation behaviors hysteresis loops. Size dependence shift effect Bi4−xNdxTi3O12 explained qualitatively by taking into account thickness ratio layer bulk film. Various shifts anamorphic shapes with different electrodes processes have been effectively...
Thin films of Nd and Mn cosubstituted bismuth titanate, i.e., Bi3.15Nd0.85(Ti3−xMnx)O12 (BNTM) (x=0, 0.005, 0.01, 0.03, 0.05, 0.1), were fabricated on Pt∕Ti∕SiO2∕Si(100) substrates at 700°C by a chemical solution deposition technique.

Thin films of Nd3+-∕V5+-cosubstituted bismuth titanate, (Bi3.15Nd0.85)(Ti3−xVx)O12 (BNTV), were fabricated by chemical solution deposition technique. For different vanadium contents (x=0.03, 0.06, and 0.09), the crystallized phase electrical properties investigated using x-ray diffraction, polarization hysteresis loops, leakage current-voltage, capacitance butterfly loops. The authors found that increasing content leads to decrease coercive field increase capacitance. film x=0.09 exhibits...
