UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...
A bstract It was shown in [1] that the effective stationary membrane equations from large D paradigm at first order admit black ring solutions flat and AdS cases, but de Sitter solution obtained [2] lies outside domain of their applicability. In this short note static is second paradigm, it satisfies equilibrium condition for thin [2]. This provides a segue into rings order.
Contact resistance among the components of a polymer exchange membrane fuel cell (PEMFC) has a crucial effect on cell performance. The geometry of the endplate plays an essential role in the contact pressure distribution over the membrane electrode assembly (MEA) and the amount of contact resistance between plates. In this work, the effects of endplate geometry on the contact pressure distribut...
A bstract Membrane nucleation, a higher dimensional analog of the Schwinger effect, is useful toy model for vacuum decay. While non-perturbative computation nucleation rates has only been accomplished at weak coupling in field theory. Here we compute spherical membranes using AdS/CFT duality, thus naturally including effects strong coupling. More precisely, consider coupled to an antisymmetric ...
Abstract This study investigates the potential of surface-patterned membranes in replacing conventional feed spacer-assisted filtration process. Two types surface patterns, namely diamond (D) and honeycomb (HC), were utilized fabrication membranes. These showed larger effective membrane area higher average porosity when compared to flat PES membrane. The D-Patterned HC-Patterned achieved pure w...
Colorectal flat-type tumors include laterally spreading tumors (LSTs) and flat depressed-type tumors. The former of which shows a predominant lateral spreading growth rather than an invasive growth. The present study examined the morphological characteristics of LSTs, in comparison with polypoid- or flat depressed-type tumors, along with the expression of atypical protein kinase C (aPKC) λ/ι, a...
Due to a growing world population and increasing welfare, energy demand worldwide is increasing. To meet the increasing energy demand in a sustainable way, new technologies are needed. The Plant-Microbial Fuel Cell (P-MFC) is a technology that could produce sustainable bio-electricity and help meeting the increasing energy demand. Power output of the P-MFC, however, needs to be increased to mak...
