The elaborately designed π-electron-rich fluorescent ligand 1,4-bis(1-carboxymethylene-4-imidazolyl)benzene (H2L), possessing bifunctional groups including the carboxylate (building units) and 4-imidazoyl (N-donor potential active sites) has been employed to construct coordination polymers. A luminescent sensor, namely [Cd(L)(phen)2]·5H2O (1), was obtained, which a one-dimensional structure. material shows blue emission maximum at 457 nm with luminescence lifetime of 488 ns quantum yield...
Abstract Introducing nanostructures into bulk thermoelectric materials is an effective strategy for reducing lattice thermal conductivity ( κ lat ). However, large numbers of hanging bonds emerge on account mismatch usually at the interfaces between and matrix, thereby significantly deteriorating carrier mobility µ H ) seriously limiting performance. Here, utilizing cointroduction Gd‐Cu 2 Te n‐type PbSe as a paradigm, zT could be greatly improved. The conduction band flattening caused by Gd...
Abstract To meet the needs of energy storage under high temperature and pressure, a high‐entropy relaxor ferroelectric ceramic, La‐modified (Bi 0.2 Na Ba Sr Ca )TiO 3 is prepared, which has excellent thermal mechanical stability. At wide range 327–689 K (tan δ < 0.01) below ≈7 GPa, material shows extraordinary functional performance.

A frozen-temperature (below -28 °C) laser tuning way is developed to optimize metal halide perovskite (MHP)'s stability and opto-electronic properties, for emitter, photovoltaic detector applications. Here freezing can adjust the competitive irradiation effects between damaging annealing/repairing. And ligand shells on MHP surface, which are widely present many materials, be frozen act as transparent solid templates MHP's re-crystallization/re-growth during tuning. With model samples of...

Forests ecosystem plays a significant role in supplying multiple services given the unique properties of forest soils, which elements C, N, and P are essential to support soil fertility site productivity. However, at different depths between plantation forests (PF) natural (NF) have not been well quantified. Therefore, current study was carried out Qilian Mountains northwest China determine difference PF NF properties, both physical (e.g., bulk density, BD) chemical pH value, contents,...
Efficient non-noble metal catalysts for oxygen reduction reaction (ORR) have been highly attractive the fabrication of cost-effective fuel cells. Metal–organic frameworks (MOFs) derived heteroatom-doped carbon-based (NC) electrocatalysts exhibited comparable electrocatalytic activity ORR as commercial Pt/C catalyst, which were dependent on their MOF precursor/template structures. In this particular work, two NC composites, NC-1100 and MnO@NC-1100 (NC, nitrogen-doped carbon), successfully...
Self-assembly of functionalized nano building blocks (NBBs) is a promising avenue for 'bottom-up' nanomaterials design. Experimental studies on polyhedral oligomeric silsesquioxane (POSS) nanocubes have revealed wide variety nanostructures from their assemblies. Our previous simulation reproduced some these and predicted unusual phase behaviours imparted by the unique geometry close packing patterns. Recent experiments further inspire us to explore effects tether topologies nanocube...
Methyl orange (MO) is a main organic water pollutants that has been attracted lot of attention; it can be degraded under photoirradiation in the presence H2O2. Herein, we developed two Cu(I)-based coordination complexes (named H2(Cu4Br6)[(Cu4Br3)(TTTMB)2(H2O)]2 (ZZY-2) and (Cu5Br6)(Cu6Br9)[Cu3Br(TTTMB)2] (ZZY-3)), which could degrade MO dye H2O2 with or without (TTTMB = 1,3,5-tris(1,2,4-triazol-1-ylmethyl)-2,4,6-trimethylbenzene). Three-dimensional (3D) frameworks ZZY-2 ZZY-3 were based on...
