High-permeance, molecular-sieving, nanoporous single-layer graphene (NSLG) membranes are highly promising for gas separation. However, the formation of cracks during transfer NSLG to a low-cost porous support is difficult avoid. These detrimental selectivity, and therefore, make scale-up gas-sieving challenging. To mitigate crack on macroporous supports, herein, we demonstrate mechanical reinfo...

This paper considers permeation through microporous or nanoporous inorganic membranes under the influence of an applied pressure gradient. In general membrane permeation may be considered as a diffusive process, driven by the gradient of chemical potential (which depends on both composition and pressure). The relative importance of these two factors varies greatly for different types of system....

Membrane technology is being researched intensively due to its potential for generating clean water. Surface modifications of nanoporous membranes could be an engineering solution to designing chlorine-tolerant membranes that would last longer in operation and thus reduce the high costs associated with membrane operations. The average pore diameter in a membrane strongly determines its selectiv...

Thin-film evaporation from nanoporous membranes is a promising cooling technology employed for the thermal management of modern electronic devices. We propose an effective one-dimensional analytical approach that can accurately predict temperature and density jump relations, rates, arbitrary membrane configurations. This accomplished through specification coefficient encompasses influence diffe...

Metallic glasses are perfect materials for preparing nanostructures by dealloying, but the obtained commonly of porous structures. Through combination chemical dealloying and ultrasonic vibration, ultrathin Cu&Ag bimetallic nanoporous membranes (NPMs) have been prepared from a Zr48Cu36Ag8Al8 MG ribbon. Furthermore, introducing oxygen into ribbon to change mechanism process, (Cu&Ag)@Ag core-shel...

The performance of nanoporous hydrogel microplugs with varying surface charge density is described in concentrating charged analytes electrokinetically in a microfluidic device. A neutral hydrogel plug with a mean pore size smaller than the size of charged analytes acts as a simple size-exclusion membrane. The presence of fixed charges on the backbone of a nanoporous hydrogel creates ion-permse...

While pore formation has been suggested as an important step in the membrane disruption process induced by antimicrobial peptides, membrane pore formation has never been directly visualized. We report on the dynamics of membrane disruption by antimicrobial peptide protegrin-1 (PG-1) on dimyristoyl-sn-glycero-phosphocholine-supported bilayer patches obtained via atomic force microscopy. The acti...

Contamination tolerances in semiconductor manufacturing processes have changed dramatically in the past two decades, reaching below 20 nm according to the guidelines of the International Technology Roadmap for Semiconductors. The move to narrower line widths drives the need for innovative filtration technologies that can achieve higher particle/contaminant removal performance resulting in clean...
