Silicon Sensors for Trackers at High-Luminosity Environment
, 2014 The planned upgrade of the LHC accelerator at CERN, namely the high luminosity (HL) phase of the LHC (HL-LHC foreseen for 2023), will result in a more intense radiation environment than the present tracking system was designed for.

Radiation Tolerance of 65nm CMOS Transistors
, 2015 We report on the effects of ionizing radiation on 65nm CMOS transistors held at approximately -20C during irradiation. The pattern of damage observed after a total dose of 1 Grad is similar to damage reported in room temperature exposures, but we observe

Evolution and impact of defects in a p-channel CCD after cryogenic proton-irradiation [PDF]
, 2017 P-channel CCDs have been shown to display improved tolerance to radiation-induced charge transfer inefficiency (CTI) when compared to n-channel CCDs. However, the defect distribution formed during irradiation is expected to be temperature dependent due ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Improving radiation tolerance with room temperature annealing of pre-existing defects
Applied Physics ExpressPre-existing defects in semiconductor devices can act as nucleation sites for radiation damage. Defects generated from mismatches in lattice constant, stiffness and thermal expansion are difficult to eliminate with thermal annealing.
