Electrochemical corrosion of multiphase stainless steel-based alloy nuclear waste forms

open access: yesnpj Materials Degradation, 2022
The electrochemical corrosion behaviors of two multiphase alloys representing waste forms made with 316 L stainless steel and different amounts of surrogate metallic fuel wastes were measured and related to the microstructures. Potentiodynamic (PD) scans

Fueling Memories [PDF]

open access: yesImmunity, 2012
A hallmark of the adaptive immune response is rapid and robust activation upon rechallenge. In the current issue of Immunity, van der Windt et al. (2012) provide an important link between mitochondrial respiratory capacity and the development of CD8(+) T cell memory.

Prediction of fly-rock during boulder blasting on infrastructure slopes using CART technique

open access: yesGeomatics, Natural Hazards & Risk, 2021
Boulder blasting is a different process from conventional bench blasting. Fly-rock produced in boulder blasting is a major safety concern due to the presence of 360° free-face which may result into excessive throw of the fragments radially up to 900 m ...

Experimental Study on a 1000W Dead-End H2/O2 PEM Fuel Cell Stack with Cascade Type for Improving Fuel Utilization [PDF]

open access: yesHydrogen, Fuel Cell & Energy Storage, 2017
Proton exchange membrane fuel cells (PEMFCs) with a dead-ended anode and cathode can obtain high hydrogen and oxygen utilization by a comparatively simple system. Nevertheless, the accumulation of the water in the anode and cathode channels might cause a
