There is a lack of effective approaches that produce polycaprolactone materials (PCL) with a high molecular weight, narrow polymer dispersity index (PDI), and fewer formation of oligomers. The immigration of the remained oligomers predominantly causes poor PCL quality and induces odor release. This limits the extensiv…
Abstract Background: To evaluate the potential differentiation ability of bone mesenchymal stromal cells(BMSCs) to pancreatic line Cells on rat acellular pancreatic bioscaffold(APB) and the effect of differentiated BMSCs for chronic pancreatitis(CP) in vivo. Methods: After BMSCs were isolated and identified, they were…

Abstract Nickel substituted cobalt ferrite − reduced graphene oxide (NCF-RGO) composite was synthesized using a facile one-pot chemical co-precipitation method. The addition of graphene oxide (GO) leads to the dimensional decrease of NCF nanoparticles (< 10 nm) in the composite, which controls the magnetic and dielect…
Abstract The BiFeO3/g-C3N4 heterostructure, which is fabricated via a simple mixing-calcining method, benefits the significant enhancement of the pyrocatalytic performance. With the growth of the g-C3N4 content in the heterostructure pyrocatalysts from 0 to 25 %, the decomposition ratio of Rhodamine B (RhB) dye after…

Simple perovskite crystals undergo structural phase transitions on cooling to low temperatures, which significantly change the material properties of the crystal. In this work we rigorously characterize the temperature evolution of permittivity of a perovskite crystal as it undergoes phase transitions. In particular,…
Abstract Zinc, magnesium, and copper substituted nickel spinel ferrite were synthesized in the form of Ni1 − x (Zn06Mg0.2Cu0.2) x Fe2O4 (where x = 0.0, 0.3, 0.5 and 0.7) via auto combustion method. The effect of the presence of these dopants on the average of crystallite, average particle size, the lattice constant, m…
Metal organic chemical vapor deposition (MOCVD) is one of the main methodologies used for thin film fabrication in the semiconductor industry today and is considered one of the most promising routes to achieve large-scale and high-quality 2D transition metal dichalcogenides (TMDCs). However, if not taken special measu…
Zhengwei Zhang and Peng Chen contributed equally to ‘Ultrafast growth of large single crystals of monolayer WS2 and WSe2’ (National Science Review, Volume 7, Issue 4, 2020, Pages 737–744, doi: 10.1093/nsr/nwz223). In the original published version of this manuscript, only Zhengwei Zhang was listed as first author. At…
This repository contains XML configuration files, POS and EPOS reconstructed APT datasets and RNG/RRNG range files, raw data, and synthetic dataset to follow our analysis made in the initial version of the paper "On Open and Strong-Scaling Tools for Atom Probe Crystallography: High-Throughput Methods for Indexing Crys…

The preparation of copper-based heterogeneous catalysts dedicated to the hydrogenation of CO2 to methanol typically relies on multi-step procedures carried out in batch. These steps are precisely tailored to introduce the active phase (Cu) and the promoters (e.g. zinc, gallium) onto a preformed support, to maximize ca…
The surface film on pure magnesium and two aluminium-containing magnesium alloys was characterised after 96 h at 95% RH and 22°C. The concentration of CO2 was carefully controlled to be either 0 or 400 ppm. The exposed samples were investigated using X-ray photoelectron spectroscopy, Fourier transform infrared spectro…
Surface Structure Modification and Hardening of Al-SI Alloys explores the hardening of material surfaces using concentrated energy flows resulting in the nanostructuring of surface layers. The authors demonstrate how these methods achieve a reduction in plastic deformation of the surface and a more uniform distributio…
In order to qualify an epoxy-based composition as a structural adhesive which can withstand shock, impact or vibration, it is essential to tailor the cross-linked matrix appropriately. Toughness with adequate strength is desired to qualify an adhesive for structural application. In this chapter, different types of fle…
Microstructural evolution is a key aspect of understanding and exploiting the structure-property-performance relation of materials. Modeling microstructure evolution usually relies on coarse-grained simulations with evolution principles described by partial differential equations (PDEs). Here we demonstrate that convo…

Coexisting phases of magnetic skyrmions and antiskyrmions have proposed to exhibit a variety of fascinating properties, owing to interactions between them. The recent discovery of the coexisting phase in a Heusler material could offer a platform for skyrmion-antiskyrmion-based spintronics. Here we report Lorentz elect…
The Front Cover shows the effect of prolonged electrochemical cycling on the integrity of an ensemble and single secondary particles of Ni-rich cathode active materials without and with modified surfaces. In search of higher capacities, Ni-rich layered lithium metal oxides are in the spotlight for applications in adva…
