Single crystals of Cd(1-x)Mn(x)Te for x = 0.1, 0.2, 0.3, 0.4 and 0.5 were grown by a modified vapour phase growth technique. ac magnetic susceptibility studies were carried out in the temperature range 14-300 K. Both the real and the imaginary parts of susceptibility indicated the formation of spin-glass phase at low temperatures. ESR spectra were recorded at room temperature (300 K) at 9.4 GHz for samples of all compositions. The line width (DeltaH) increased with Mn content.

Polymeric membranes with great processability are attractive for the H/CO separation required for hydrogen production from renewable biomass with carbon capture for utilization and sequestration. However, it remains elusive to engineer polymer architectures to obtain desired sub-3.3 Å ultramicropores to efficiently sieve H from CO.

We report enhanced proton conductivity promoted by a structural phase transition of MFM-504(Cu)-DMF to MFM-504(Cu)-MeOH and to MFM-504(Cu)-OH via ligand substitution upon exposure to MeOH and HO vapors, respectively. MFM-504(Cu)-DMF can be synthesized by the solvothermal reaction of Cu(NO)·3HO and the flexible zwitterionic ligand, imidazolium-1,3-bis(methylenedicarboxylate) (imidc), to afford a unique layered interwoven network structure. MFM-504(Cu)-OH shows a proton conductivity of 5.

Perovskite smart windows (PSWs) are widely investigated owing to excellent thermochromic properties, while restricted by poor transition performance and cycle stability. Herein, dimethyl sulfoxide vapor is utilized as an induction reagent for rapid reversible switching at room temperature between the colored and bleached phases. To obtain PSWs with different optical properties and transition performance, red CsPbIBr, yellow RbCsPbIBr and brown CsSnPbIBr are prepared through alloying.

This research evaluated how addition of biochar and zeolite affected nitrogen transformation and retention during the composting of kitchen waste. Four treatments, control (CK), 10 % biochar (B), 10 % zeolite (Z), and 5 % biochar +5 % zeolite (BZ) were used to study nitrogen transformation and retention. The results showed that biochar and zeolite can significantly reduce the loss of NH-N during the thermophilic phase (CK: 42.

The objective of this study was to prepare a microcapsule system composed of the inner microenvironment (probiotics), middle oil layer (soybean oil and polyglycerol polyricinoleate) and outer coacervate (whey protein and gum arabic) using double emulsification technique coupled with complex coacervation to encapsulate probiotics, and to evaluate the effect of adding krill oil (KO) to the middle oil layer on microcapsule structure and probiotic stability. The results of Fourier transform infrared spectroscopy and Scanning electron microscopy confirmed that whey protein may capture phospholipids in KO through hydrogen bonds, resulting in the formation of a more compact coacervate. Due to the compact coacervate enhanced the vapor transport barrier and reduced water evaporation during low-temperature dehydration, probiotics encapsulated in KO-supplemented microcapsules revealed less cell damage and a higher survival rate after freeze-drying.
