http://onlinelibrary.wiley.com/doi/10.1002/adfm.201704757/full Hydrogels are the focus of extensive research due to their potential use in fields including biomedical, pharmaceutical, biosensors, and cosmetics. However, the general weak mechanical properties of hydrogels limit their utility. Here, pristine silk fibroin (SF) hydrogels with excellent mechanical properties are generated via a binary-solvent-induced conformation transition (BSICT) strategy.

Nobel laureate Randy Schekman: How journals like Nature, Cell and Science are damaging science

An article on the Guardian here. Critics will say Shelkman has founded his own open access journal, here, probably competing with Nature, Cell and Science, which explains a lot.

SHEN Zhiyuan-Regarding to use the effective Kirshhoff plate property to model a microbeam

_{I am studying the vibrational behaviour of a microbeam made of a polymer (Fig. 1). I came across your paper "Equivalent models of corrugated panels" and find the effective material modelling reported in that paper very helpful for solving my modelling problem. I got some problems that I want to seek for your advices.}

I have few questions:

1- why most the experimental fatigue studies on metal or metal-composites in the literature were adopted a frequency less than 35Hz (the majority of these test have conducted using 20Hz).

I ran into some articles mentioned that the frequency (0-100Hz) has a marginal effect on the fatigue life of metal. is that the only answer

A thermo-elasto-plastic theory for special Cosserat rods

Submitted by Ajeet Kumar on Tue, 01/02/2018 - 23:47

A general framework is presented to model coupled thermo-elasto-plastic deformations in the theory of special Cosserat rods. The use of the one-dimensional form of the energy balance in conjunction with the one-dimensional entropy balance allows us to obtain an additional equation for the evolution of a temperature-like one-dimensional field variable together with constitutive relations for this theory. Reduction to the case of thermoelasticity leads us to the well known nonlinear theory of thermoelasticity for special Cosserat rods.
