A (001)-oriented NaNbO3–LaCoO3:Mn thin film with enhanced ferroelectric properties was successfully deposited on a SrRuO3-buffered LaAlO3 substrate by radiofrequency magnetron sputtering. This epitaxial thin film modified by element doping shows a tetragonal ferroelectric structure and large remanent polarization (31 μC cm−2) with high Curie temperature (450 °C). The polarization fatigue tests demonstrate an improved fatigue resistance due to the reduced oxygen vacancies by element doping. Furth...

Insulin is naturally released from the β-cells in the pancreas and plays a crucial role in controlling the blood sugar levels in the body. However, it was found that when insulin molecules aggregate to produce insulin fibrils they may yield to serious therapeutic problems, such as glycemic control. Therefore, there is an interest to investigate the mechanisms of the formation and the structures of insulin fibrils. It is also known that Zn2+ ions play a key role in the synthesis and action of ins...

The structurally simple complex {FeII[tren(6F-py)3]}(BF4)2 [tren(6F-py)3 = tris(3-aza-4-(6-fluoro-2-pyridyl)-3-butenyl]amine] undergoes an abrupt spin transition (ST) with the critical temperature T1/2↓ = 243 K on cooling and T1/2↑ = 281 K on heating, with a hysteresis 38 K wide, while the ClO4– congener shows ST spanning the room temperature region at T1/2↓ = 267 K and T1/2↑ = 295 K with a hysteresis 28 K wide. Calorimetric data confirm occurrence of a highly energetic ST process, while multi-t...

Defective UiO-66 with suspended thiol functional groups is constructed and used as a template for palladium nanoparticle synthesis. The anchoring thiol groups not only bind the nanoparticles firmly but also help in their uniform distribution throughout the MOF structure. The Pd nanoparticle incorporated UiO-66 acts as an excellent heterogeneous catalyst for the complete reduction of toxic hexavalent chromium Cr(VI) to Cr(III) within a very short time under visible light in aqueous medium.

It is of great significance for white light-emitting diodes (wLEDs) to explore new, efficient and stable inorganic phosphors excited by wideband near-ultraviolet (n-UV) light. A new type of efficient emission-tunable Ce3+/Mn2+ doped Ca2YHf2Al3O12 (CYHAO) garnet phosphor which can be excited by n-UV light is studied in this work. Due to the effective energy transfer (ET) from Ce3+ to Mn2+ in CYHAO, CYHAO:0.09Ce3+,xMn2+ phosphors have a wide excitation band in the 370–470 nm region with a peak at ...

UiO-66, reported in 2008, inspired the ongoing chemistry of the group 4 metal-organic frameworks and it is still one of the most studied MOFs due to its exceptional stability. The tightness of their building blocks and bond strength make it tough accessing to new topologies, unless building blocks are changed or defect engineering is employed, which in turn lead to different nominal stoichiometry. However, well selected structure directing agents and harsh synthesis conditions allowed to isolate...

Metal–organic framework (MOF) membranes with an ultra-small pore size (<4 A) have shown great prospects in the highly selective separation of small gas molecules such as hydrogen, but their narrow channels may result in a low gas permeance. To improve the gas permeance of ultra-microporous MOF membranes, a stable covalent organic framework (COF) with large and uniform pores is doped to construct a binary COF/MOF all-nanoporous composite (ANC) membrane, equivalent to reducing the effective membra...

A novel Eu(III) metal–organic framework (MOF) featuring 3-fold interpenetration shows multi-responsive behaviors owing to the combination of charge transfer, electron transfer, and energy transfer between different ingredients (the electron-deficient tris(pyridinium)triazine (tpt) chromophore, the electron-rich naphthalene chromophore, the Eu(III) luminophore, and the guest anion). The interframework naphthalene-to-tpt charge transfer dictated by framework interpenetration serves to sensitize th...

Ligand engineering based on a closo-B12-cage has been practiced in this work to design a series of stable gas-phase dianions [B12(ECX)12]2− (E = N, P, and As; X = O, S, and Se) via ab initio calculations. The calculated second electron affinities ranging from 1.2 to 3.4 eV indicate that these dianions are electronically stable against electron auto-detachment. Their electronic structures were analyzed based on molecular orbitals and natural bond orbitals. We found that in these designer dianions...

Transition metal diborides (TMdBs AlB2-type P6/mmm) electrocatalysts have aroused much attention toward the hydrogen evolution reaction (HER), because MoB2 (P6/mmm) exhibits superior catalytic activity. However, the understanding of the activity in the different lattice planes of TMdBs is still limited, which impedes the accurate design of new superior catalyst based on TMdBs. In this work, a borophene subunit was utilized to form AlB2-type CrB2 (P6/mmm) for modulating the d-band center. It was ...
