The influence of helium-induced defects on the migration of strontium implanted into SiC above critical amorphization te...

Published in Frontiers in Materials

The presence of radiation-induced defects and the high temperature of implantation are breeding grounds for helium (He) to accumulate and form He-induced defects (bubbles, blisters, craters, and cavities) in silicon carbide (SiC). In this work, the influence of He-induced defects on the migration of strontium (Sr) implanted into SiC was investigate...

Hot-injection synthesis of lead-free pseudo-alkali metal-based perovskite (TlSnX3) nanoparticles with tunable optical pr...

Published in Frontiers in Materials

The commercialization of organo-inorganic hybrid perovskite materials for optoelectronic applications is limited owing to the restriction of lead (Pb) usage in consumer electronics and the instability of organic cations in the perovskite structure. To address these challenges, we synthesize TlSnX3 (X = Cl, Br, and I) perovskite nanoparticles (NPs) ...

A study on the preparation of superhydrophobic Silane-MXene modified melamine foam and its oil-water separation performa...

Published in Frontiers in Materials

In recent years, oil spills and organic pollution have caused severe damage to the ecological environment. Therefore, the treatment of oily wastewater has become a serious challenge. Here, with the help of melamine foams as a substrate, MXene nano-rough structures were built, and cetyltrimethoxysilane was grafted onto their surfaces to create an oi...

Polyimide aerogel/aramid fiber composite with high mechanical strength and thermal insulation for thermal protective clo...

Published in Frontiers in Materials

Polyimide (PI) aerogel, as a new organic aerogel material, has the excellent thermal properties of polyimide and the characteristic of high thermal insulation of aerogels, and has gained increasing attention. In this work, using PI aerogel as the matrix material and aramid fiber as the reinforcement material, controllable flexible PI aerogel/aramid...

Experimental study into the propagation and attenuation of blasting vibration waves in porous rock-like materials

Published in Frontiers in Materials

Rock blasting vibration can cause harm to the surrounding environment. This article aims to investigate the propagation and attenuation of vibration waves in the blasting excavation of porous rock. Similar materials were used to simulate porous rock media and indoor blasting experiments were conducted on 12 porous rock-like models poured to estimat...

Optimization study of finite element simulation based on multi-layer structure and anisotropic CFRP

Published in Frontiers in Materials

Introduction: Current research has mostly simplified CFRP components as isotropic media or homogenized them as anisotropic media, which fails to present the actual acoustic propagation behavior inside the CFRP components and restricts the accuracy of decoupling sound line tracking results and defect feature information. Method: Based on clarifying ...

Achieving high-quality silver sintered joint for highly-reliable schottky barrier diodes via pressureless method

Published in Frontiers in Materials

The fabrication of silver joints was done using the pressureless sintering technology to suit the demand of high-reliability schottky barrier diodes (SBD). Porosity of 10.6% and shear strength of 39.6 MPa were reached under the optimized parameters of 290°C sintering temperature and 40 min residence time. The sintered joint demonstrated good mechan...

Porous and highly responsive polymeric fabricated nanometrices for solubility enhancement of acyclovir; characterization...

Published in Frontiers in Materials

Solubility is one of the major factors which affects several therapeutic mioeties in terms of their therapeutic efficacy. In the current study, we presented a porous and amorphous nanometrices system for the enhancement of the solubility of acyclovir. The polymeric network was fabricated by crosslinking polyethylene glycol-6000, polycaprolactone, a...
