ANALYSIS THE FORMULA OF STRESS INTENSITY FACTORS FOR THE COMPACT TENSION SHEAR TEST

open access: yesJixie qiangdu, 2021
The Compact Tension Shear( CTS) specimen proposed by Richard is a commonly test type used in mixed ModeI/II loading. The formula of stress intensity factors( SIFs) for the CTS test has already given by relevant literature.

Direct dendronization of polystyrenes using dendritic diarylcarbenium ion pools

open access: yes, 2011
Dendritic diarylcarbenium ions reacted with unfunctionalized polystyrenes to give dendronized polymers, which were characterized by MALDI-TOF MS and AFM.

Enhanced Electrochemiluminescence from 3D Nanocavity Electrode Arrays

open access: yesSensors and Actuators Reports, 2022
3D arrays comprising interconnected voids have been created using nanosphere lithography (2000≤diameter≤240 nm) followed by electrodeposition of gold. The top surface was blocked with 11-mercaptoundecanoic acid and then the templating polystyrenes were ...

Radical Chain End Chemical Transformation of SG1-Based Polystyrenes

open access: yes, 2010
International audienceRadical chain end functionalization of polystyrene previously prepared by NMP using the SG1 nitroxide was investigated. Hydroxy-functional polystyrenes were easily prepared by two different pathways: via an exchange with TEMPO ...

One-Step Synthesis of Dendritic Highly Branched Polystyrenes by Organotellurium-Mediated Copolymerization of Styrene and a Dienyl Telluride Monomer [PDF]

open access: yes, 2019
Dendritic highly branched polystyrenes (HB‐PSts) were prepared by a one‐step copolymerization of dienyl telluride 6 and St in the presence of organotellurium chain transfer agent 2.

Thermodynamic differences between deuterated and protonated polystyrenes using reversed phase liquid chromatography

open access: yes, 2005
Deuterated compounds are generally considered to possess very similar properties to their protonated analogues. Reversed phase liquid chromatography (RPLC) was used to measure thermodynamic interactions between deuterated and protonated n-butyl ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Synthesis of branched polystyrenes via cationic polymerisation

open access: yes, 2006
Branched polystyrenes have been prepared rapidly (within 15 min) and in good yields (40–99%) in dichloromethane solution at 0 °C via cationic copolymerisation of styrene (St) with divinylbenzene (DVB) using SnCl4 as the initiator. All reaction components

Synchrotron X-ray Scattering Characterization of the Molecular Structures of Star Polystyrenes with Varying Numbers of Arms

open access: yes, 2018
We have synthesized well-defined multiarmed star polystyrenes, with 6, 9, 17, 33, and 57 arms, and studied their molecular shapes and structural characteristics in a good solvent (tetrahydrofuran at 25 degrees C) and in a theta (Theta) solvent ...
