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

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

Electrochemical Impedance Spectroscopy for Investigation of Different Losses in 4-cells Short Stack with Integrated Humidifier and Water Separator [PDF]
Hydrogen, Fuel Cell & Energy Storage, 2016 Electrochemical impedance spectroscopy (EIS) is a suitable and powerful diagnostic testing method for fuel cells (FCs) since it is non-destructive and provides useful information about FC performance and its components. In this study, for the first time,

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
