Changes in the structure of tethered chain molecules as predicted by density functional approach

open access: yesCondensed Matter Physics, 2011
We use a version of the density functional theory to study the changes in the height of the tethered layer of chains built of jointed spherical segments with the change of the length and surface density of chains.

Wage Share, Market Power and Unionism: Some Contrary U.S. Evidence [PDF]

open access: yes, 1984
In a recent article, Cowling and Molho (1982) presented empirical evidence on the relationships among the wage share, market power, and unionism in the U.K.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Molecular Dynamics Simulation of Semiflexible Polyampholyte Brushes - The Effect of Charged Monomers Sequence

open access: yes, 2009
Planar brushes formed by end-grafted semiflexible polyampholyte chains, each chain containing equal number of positively and negatively charged monomers is studied using molecular dynamics simulations.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Lubrication by Polyelectrolyte Brushes [PDF]

open access: yesMacromolecules, 2014
We develop a scaling model relating the friction forces between two polyelectrolyte brushes sliding over each other to the separation between grafted surfaces, number of monomers and charges per chain, grafting density of chains, and solvent quality.

Investigation of the influence of the parameters of a hydropneumatic accumulator on the operation of the device for controlling the position of a cylindrical brush of a communal machine

open access: yesНаучно-технический вестник Брянского государственного университета, 2022
The article is devoted to the actual problem of improving the quality of cleaning roads and sidewalks by communal machines with brush working equipment. One of the main parameters of the working process of a communal machine with brush working equipment,

Anti‐Swelling Textile Power Generator with 1D Nanoscale Channel Alignment in Nanofiber/Graphene Hybrid Yarns

open access: yesAdvanced Functional Materials, EarlyView.
A nanofiber/graphene hybrid yarn with 1D oriented nanoscale channel is constructed via bath electrospinning followed by a functionalization process, yielding exceptional anti‐swelling and weaving abilities. When configured into a waterproof fabric through series‐parallel connection of 62‐cm yarns, an output power of 31.96 µW is achieved, which could ...

Brushed Aside and Silenced [PDF]

open access: yesDevelopmental Cell, 2008
Mammalian genomes are highly organized in the 3D space of cell nuclei, but whether this affects gene function is unclear. Three papers now show that spatial relocation of a gene directly affects expression, and surprisingly, that of its neighbors.

Surface Properties of a Biocompatible Thermoplastic Polyurethane and Its Anti-Adhesive Effect against E. coli and S. aureus

open access: yesJournal of Functional Biomaterials
Thermoplastic polyurethane (TPU) is a polymer used in a variety of fields, including medical applications. Here, we aimed to verify if the brush and bar coater deposition techniques did not alter TPU properties.
