Demulsifier-Inspired Superhydrophilic/Underwater Superoleophobic Membrane Modified with Polyoxypropylene Polyoxyethylene Block Polymer for Enhanced Oil/Water Separation Properties

open access: yesMolecules, 2023
Demulsifiers are considered the key materials for oil/water separation. Various works in recent years have shown that demulsifiers with polyoxypropylen epolyoxyethylene branched structures possess better demulsification effects. In this work, inspired by

On the separability of graphs [PDF]

open access: yesDiscrete Mathematics, 2013
Abstract Recently, Cicalese and Milanic introduced a graph-theoretic concept called separability. A graph is said to be k -separable if any two non-adjacent vertices can be separated by the removal of at most k vertices. The separability of a graph G is the least k for which G is k -separable.

The Effect of C/Si Ratio and Fluorine Doping on the Gas Permeation Properties of Pendant-Type and Bridged-Type Organosilica Membranes

open access: yesMembranes, 2022
A series of pendant–type alkoxysilane structures with various carbon numbers (C1–C8) were used to fabricate sol–gel derived organosilica membranes to evaluate the effects of the C/Si ratio and fluorine doping. Initially, this investigation was focused on

Permission-based separation logic for message-passing concurrency [PDF]

open access: yes, 2010
We develop local reasoning techniques for message passing concurrent programs based on ideas from separation logics and resource usage analysis. We extend processes with permission-resources and define a reduction semantics for this extended language ...

Experimental investigation of anion exchange membrane water electrolysis for a tubular microbial electrosynthesis cell design

open access: yesCatalysis Communications, 2022
Tubular water splitting electrolyzer was adapted to neutral pH conditions for the in-situ H2 supplying microbial electrosynthesis design. The electrolyzer was optimized to reduce ohmic losses and provide adequate gas separation.
