Auxetic materials are a class of possessing negative Poisson's ratio. Here, we established novel method for preparing auxetic foam from closed-cell polymer based on the steam penetration and condensation (SPC) process. Using polyethylene (PE) as an example, foams treated by SPC process presented ratio during stretching compression testing. The effect steam-treated temperature time conversion efficiency negative-Poisson's was investigated, mechanism forming reentrant structure discussed....
To investigate the potential role of human papillomavirus (HPV) infection in pathogenesis esophageal carcinomas Anyang area China, we have evaluated specimens collected by balloon cytology examination from volunteers two regions with significantly different incidences carcinoma. 138 donors were a village county an carcinoma (EC) age-adjusted mortality rate 132x10(5), remaining 68 resident second another EC 52x10(5). Specimens using both polymerase chain reaction (PCR) amplification and situ...
Abstract BACKGROUND Human papillomavirus (HPV) plays an important role in the development of carcinomas at various body sites. It was found previously that p53 codon 72 polymorphism (C/G) is a high‐risk factor for HPV‐associated cervical carcinoma. However, it still considered controversial several studies and esophageal METHODS In current study, authors used allele specific polymerase chain reaction (PCR) method to analyze correlation between HPV‐associated, noncancerous epithelium as well...
Esophageal carcinoma is characterized by a widely ranged incidence variation among the different geographic regions. Anyang county in Henan Province of North China with highest prevalence esophageal carcinoma. Human papillomavirus (HPV) infection has been linked to etiology cancer this area. In study, we investigated correlations polymorphisms at low molecular weight polypeptide ( LMP ) and transporters antigen processing TAP genes, risk DNA extracted from either tumor specimens or...
A series of polypropylene-g-poly(ethylene-co-1-butene) (PP-g-EBR) graft copolymers with well-defined long chain branched (LCB) molecular structures were synthesized via the combination coordination polymerization and anionic polymerization. The structure–property relationships PP-g-EBR systematically investigated. structural information was clarified by characterization 1H NMR SEC equipped triple detectors. DMA measurements demonstrated that amorphous EBR branches miscible PP backbones. melt...
So far, negative Poisson's ratio foam (auxetic foam) is usually prepared by the transformation of conventional polymer foam, and it a challenge to prepare auxetic directly from resin. In this work, novel method based on synergism between phase transition water permeability rate difference CO2 blowing agent air in foaming process put forward Using method, herein, nylon elastomer (NE) with behavior successfully NE resin one-pot inside an autoclave aided water; obtained has value -1.29...
Abstract Oxidative stress has been considered as a major cause of cellular injuries in variety clinical abnormalities, especially prominent neural diseases. One the effective ways to prevent reactive oxygen species (ROS) mediated injury is dietary or pharmaceutical augmentation some free radical scavenger. Water‐soluble amino‐fullerene derivative novel compound that behaves scavenger with excellent biocompatibility. In present study, we synthesized β‐alanine C 60 derivative. The product was...
Due to the development of printing materials, light-cured 3D is playing an increasingly important role in industrial and consumer markets for prototype manufacturing conceptual design due its advantages high-precision high-surface finish. Despite widespread use, it still difficult achieve requirements large volume, high resolution, speed. Currently, traditional technologies based on stereolithography, such as regular DLP SLA, can no longer meet processing size rate. This paper introduces a...
