Fabrication of ion imprinted chitosan-polyethylene glycol-polyvinyl alcohol hybrid membrane for selective recovery of Nd(III).

Reclamation of rare earths from secondary sources is in line with both environmental remediation and sustainable utilization of rare earth resources. Herein, neodymium Nd(III) imprinted polyethylene glycol-polyvinyl alcohol hybrid membrane (IIP-CS-PEG-PVA) with high selectivity, increased specific surface area, acid stability and easy recyclability was constructed using chitosan (CS) as functional monomer, polyethylene glycol (PEG) as porogenic agent, polyvinyl alcohol (PVA) as filmogen, and Nd(III) as template ion. Batch adsorption indicates, adsorption of IIP-CS-PEG-PVA for Nd(III) is induced by electrostatic interaction, reaching rapid equilibration in 35 min at pH = 5.

Effect of Microalloying Rare-Earth Nd on Microstructure Evolution and Mechanical Property of Cu Alloy.

Cu alloys have been widely used in the manufacture of liners because of their high density, good plasticity, and excellent thermal conductivity. In order to achieve excellent jet stability and penetration performance, it is necessary to further improve the mechanical properties of Cu-based liners. Nevertheless, the simultaneous enhancement of strength and ductility of the Cu alloys remains a huge challenge due to the strength-ductility trade-off phenomenon of metals/alloys.

Structures, simulated photoelectron spectroscopy, and electronic properties of CuASi(A = Sc, Cu, x ≤ 13) clusters: Relatively stable neutral pentagonal bipyramid structures of CuASi.

Structural design and optimization, simulated photoelectron spectroscopy, electronic properties and chemical bond analysis of CuASi(A = Sc, Cu, x ≤ 13) clusters were systematically studied using the PBE scheme to integrate with global search program of ABCluster. Firstly, neutral MS (the most stable structures) of CuASi of the basic 1 + 5 + 1 structures (1 metal + 5 silicons + 1 metal atoms) can be found as the basic units for assembling more lager clusters under the condition of neglecting distortions and minor changes. If the Cu atoms in CuSi(x ≤ 13) systems was replaced by one Sc atom, the geometries of MS will be reconstructed.

Effect of Adding Benzyl Alcohol on Hydrogen Production from Lignite.

Combustion power generation is still the main way of lignite utilization, but lignite combustion will produce a lot of toxic gases, so how to make lignite clean utilization has become an urgent problem to be solved. Hydrogen is an environmentally friendly, zero-carbon emission clean energy because microorganisms can degrade brown coal to produce hydrogen. Therefore, in this experiment, the anaerobic hydrogen production experiment of lignite was carried out, and the influence of different concentrations of benzyl alcohol on hydrogen production of lignite was studied.

Supercurrent and Superconducting Diode Effect in Parallel Double Quantum Dots with Rashba Spin-Orbit Interaction.

We study theoretically the supercurrent and the superconducting diode effect (SDE) in a structure comprising parallel-coupled double quantum dots (DQDs) sandwiched between two superconductor leads in the presence of a magnetic flux. The influence of the Rashba spin-orbit interaction (RSOI), which induces a spin-dependent phase factor in the dot-superconductor coupling strength, is taken into account by adopting the nonequilibrium Green's function technique. This RSOI-induced phase factor serves as a driving force for the supercurrent in addition to the usual superconducting phase difference, and it leads to the system's left/right asymmetry.

Analysis of forming mechanism and influencing factors of thermoacoustic plate end temperature difference.

In order to explore the formation mechanism and influencing factors of the temperature difference between two ends of the plate stack, an expression of the temperature change of the stack with time was established based on the two-dimensional heat conduction equation. Based on this, the finite element model of heat transfer between a single thermoacoustic plate stack and the gas above it is established in Ansys, and the temperature of the plate stack is solved. When the sound field is constant, the variation law of the temperature of the stack with the working time and space is obtained, and the formation mechanism of the temperature difference between the two ends of the plate stack is revealed.
