BackgroundESCRT-III proteins are involved in many membrane remodeling processes including multivesicular body biogenesis as first discovered in yeast. In humans, ESCRT-III CHMP2 exists as two isoforms, CHMP2A and CHMP2B, but their physical characteristics have not been compared yet.ResultsHere, we use a combination of techniques on biomimetic syste...
Physical and mechanical properties of the drug-incorporated polymer play a significant role in the release behavior from the drug carriers. Understanding the relative extent of variation in the physical and mechanical properties of the polymer makes it possible to improve the design of polymer carriers to obtain better release profile and increase ...
In this work, Graphene NanoPlatelets (GNP)/Aluminum (Al) composites reinforced from 0 wt% to 2.0 wt% GNP were studied. All different composition powders were stirred for 2 h at a speed of 35 rpm in a V-type mixer to obtain a homogeneous dispersion. Then the compositions were synthesized by ultra-high frequency induction heated sintering (UHFIHS) at...

Attempts to modify cement-based mixtures and to improve their properties have always attracted the attention of researchers. Favorable effects of nanoparticles, such as small particle size, high reactivity, and great surface area, have made them be used as one of the best replacements of cement. This paper aims to review the previous researches con...

Equal channel angular pressing (ECAP) was used to process Mg-4Zn-1Mn alloy at 300 °C using route Bc up to 4 pass with a cumulative strain of 3.2. Optical microscope (OM), microstructures results shows homogenized sample grain size was 260 µm, after 4 pass ECAP grain size was decreased to 6 µm. Electron back-scattered diffraction (EBSD) shows the mi...
The work reported here is the first study aimed at providing a full screening of a real unsortable non-recycled post-consumer WEEE stream free of brominated flame retarded plastics, separated using on-line X-ray detection, toward its recycling. In the existing sorting lines, up to 40% of plastics from waste electrical and electronic equipment (WEEE...

This study was carried out using bleached softwood Chemi-Thermo-Mechanical Pulp to evaluate the influence of Molded Pulp Products’ manufacturing process parameters on the finished products’ mechanical and hygroscopic properties. A Taguchi table was done to make 8 tests with specific process parameters such as moulds temperature, pulping time, dryin...

The GMAW process with rotating electrode (GMAW-RE) is a variation of the conventional GMAW process, where the electrode is submitted to a rotating movement, with pre-established rotation diameter and frequency. The method improves the lateral fusion along the sidewalls and contributes to the improvement of narrow gap welding, with significant gains...

Interactions of dislocations with coherent twin boundaries contribute to strength and ductility in metals, but investigating the interaction mechanisms is challenging. Here the authors unravel these mechanisms through quantitative in-situ transmission electron microscopy observations in nickel bi-crystal samples under tensile loading.

The condition of the Picasso’s Science and Charity has always been a matter of concern for the Conservation Department at the Museu Picasso in Barcelona. In the last few years, several historical and technical lines of research (based on vintage photographs and physicochemical studies) have increased the understanding of the painting’s materials an...
