A visualization of the damage in Lead Tungstate calorimeter crystals after exposure to high-energy hadrons

open access: yes, 2012
The anticipated performance of calorimeter crystals in the environment expected after the planned High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN has to be well understood, before informed decisions can be made on the need for ...

Proteostasis collapse is a driver of cell aging and death. [PDF]

open access: yes, 2019
What molecular processes drive cell aging and death? Here, we model how proteostasis-i.e., the folding, chaperoning, and maintenance of protein function-collapses with age from slowed translation and cumulative oxidative damage.

Effect of hygrothermal environment on mechanical properties and damage mechanism of CFRP

open access: yesCailiao gongcheng, 2019
The moisture absorption properties of carbon fiber reinforced plastics (CFRP) laminates treated with three kinds of hygrothermal environments (relative humidity 85% RH, temperature 25, 70, 85℃ respectively) were investigated by accelerated moisture ...

The influence of toughening-particles in CFRPs on low velocity impact damage resistance performance

open access: yes, 2014
The role of particle-toughening for increasing impact damage resistance in carbon fibre reinforced polymer (CFRP) composites was investigated. Five carbon fibre reinforced systems consisting of four particle-toughened matrices and one system containing ...
