We initiated a self-adjusted oxygen-partial-pressure approach to prepare high-performance Li2MnO3–LiMO2 cathode material. Four different lithium resources, lithium acetate, lithium hydrate, lithium carbonate, and lithium nitrate were used to create the local oxygen partial pressure over the samples. Since the melting…
A series of unsymmetrical α-diimine compounds L1–L5 bearing the dibenzhydryl substituent (−CH(Ph)2) has been prepared and characterized by IR and NMR (1H/13C) spectroscopy as well as by elemental analysis. Their corresponding nickel dibromide complexes (Ni1–Ni5) were synthesized and characterized, and single crystal X…
Solid supported platinum(0) (SS-Pt) nanoparticles were developed as a heterogeneous catalyst following a reduction/deposition method and characterized by SEM, TEM, EDX and XRD analysis. The SS-Pt catalyst was applied in the chemo-selective reduction of nitroarenes to N-arylhydroxylamines using hydrazine hydrate as a h…
Thin elastic spherical shells are known to exhibit a buckling instability at a finite external pressure. We study how this buckling is influenced by a weak region in an otherwise uniform shell, focusing on the case of a single small circular soft spot that is thinner than the rest of the shell. Using numerical simulat…
The piezoelectric potential screening by large excess electrons in nominally undoped ZnO has limited the energy conversion efficiency of the ZnO nanogenerators (NGs). In this study, we report a simple and effective approach to enhance the piezoelectric output performance of the ZnO NGs by forming a CuO–ZnO heterostruc…
We report a highly active and stable nanocomposite photocatalyst for H2 generation under sunlight which consists of a rational assembly of CdS nanoparticles, Ni clusters, and ultrathin titanate nanodisks, highly dispersed in water.
The novel homochiral metal-organic framework CFA-1 (Coordination Framework Augsburg-1), [Zn5(OAc)4(bibta)3], containing the achiral linker {H2-bibta = 1H,1'H-5,5'-bibenzo[d][1,2,3]triazole}, has been synthesised. The reaction of H2-bibta and Zn(OAc)2·2H2O in N-methylformamide (NMF) (90 °C, 3 d) yields CFA-1 as trigona…
Hierarchical flower-like TiO₂ with an anatase-rutile heterojunction was prepared by a hydrothermal process in the presence of titanium trichloride and poly(sodium-p-styrenesulfonate) (PSS). The morphology evolution process and formation mechanism of the as-obtained products were investigated in detail. It was found th…
N-Vinylcaprolactam (NVCL) was copolymerized statistically for the first time in a controlled manner with hydrophilic N-vinylamide or hydrophobic vinylester monomers in order to precisely tune up and down the lower critical solution temperature (LCST) of the resulting copolymers. The incorporation of these segments in…
An enantioselective catalyst, consisting of a chiral Mn(III)salen complex entrapped in the MIL-101 metal organic framework, is reported. For the first time, we assemble a robust MOF-cage around a chiral complex. The heterogeneous catalyst shows the same selectivity as the homogeneous complex and is fully recyclable. T…
The salt effect of NaxA (A = SO42−, Cl−, NO3−, etc.) on the hydrothermal carbonization of biomass is reported. It is a new catalyst and recyclable template to more simply and effectively prepare carbon-based materials, such as porous carbon-coated anode materials (e.g., Fe3O4@porous-C) in lithium-ion battery applicati…
Modeling the Steady-State and Transient Response of Polarized and Non-Polarized Proton-Conducting Doped-Perovskite Membranes, Kee, Robert J., Zhu, Huayang, Hildenbrand, Brett W., Vøllestad, Einar, Sanders, Michael D., O’Hayre, Ryan P.
A novel class of redox-responsive cationic supramolecular polymer with effective DNA condensation ability and H2O2-induced DNA release behavior has been successfully constructed from small molecules. This supramolecular polymer can be used in vitro as a promising nonviral vector for gene therapy.
A low-cost and easily-synthesized organic hole transport material (HTM) X3 bearing triphenylamine units and an organic dye was utilized for solid state dye sensitized solar cells (ssDSCs), which have achieved the power conversion efficiencies of 5.8% and 7.1% under 1 sun and 0.46 sun, respectively, outperforming the s…
Hydroxyapatite (HA), as the main inorganic constituent in vertebrate hard tissues, is an important biomaterial for the application in drug delivery and protein adsorption. Herein, we report a simple and green hydrothermal synthesis of HA nanorods and nanowires by using the biocompatible biomolecule riboflavin-5′-phosp…
The sorbitol conversion in a molten salt hydrate medium (ZnCl2; 70 wt% in water) was studied. Dehydration is the main reaction, initially 1,4- and 3,6-anhydrosorbitol are the main products that are subsequently converted into isosorbide; two other anhydrohexitols, (1,5- and 2,5-), formed are in less amounts and do not…
A copper(I) halide-based compound with a formula of [Cu4I3(DABCO)2]I3 (DABCO = N,N'-dimethyl-1,4-diazabicyclo[2.2.2]octane) has been prepared by solvothermal reactions. This compound has been characterized by single-crystal X-ray diffraction, elemental analysis, IR, TG, XPS and powder X-ray diffractions. Structure ana…
This paper describes the exploration of a synergic effect within n-type inorganic–p-type organic nano-hybrids in gas sensors. One-dimensional (1D) n-type SnO2–p-type PPy composite nanofibers were prepared by combining the electrospinning and polymerization techniques, and taken as models to explore the synergic effect…
A highly active catalyst based on PdCo alloy nanoparticles supported on polypropylenimine dendrimers, grown on graphene nanosheets, was synthesized and used for carbon–carbon cross-coupling Sonogashira reactions. The prepared catalyst facilitated a facile, efficient and environmentally friendly procedure for the Sonog…
The realisation of technologically high potential molecular materials as an innovative replacement for currently used materials requires sensible molecular design and subtle implementation. One such research concept "liquid chemistry" has recently been introduced as a third-generation of liquid materials after the fir…
