Application of Screen Printing in Flexible Miniature Thermocouple Process Development

International Journal of Electrochemical Science, 2015
Thermocouple is a highly effective means of determining exactly fuel cell temperature. This work presents a method for producing flexible micro thermocouple by using screen printing rather than micro-electro-mechanical systems (MEMS). The proposed method

Enhancement of Catalytic Activity and Durability of Pt Nanoparticle through Strong Chemical Interaction with Electrically Conductive Support of Magnéli Phase Titanium Oxide

Nanomaterials, 2021
In this study, we address the catalytic performance of variously sized Pt nanoparticles (NPs) (from 1.7 to 2.9 nm) supported on magnéli phase titanium oxide (MPTO, Ti4O7) along with commercial solid type carbon (VXC-72R) for oxygen reduction reaction ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Developing Hybrid–Power Fuel Cells with a Low–Pressure Hydrogen–Storage System used in an Electric Forklifts

International Journal of Electrochemical Science, 2017
In this study, we prepared a lab–built water–cooled fuel cell hybrid power system. This system contains 2.7 kW proton exchange membrane fuel cells, ultracapacitors, and lithium batteries that are actually constructed in a commercial electric forklift ...

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Model-based analysis of the current interrupt technique for the characterisation of porous gas diffusion electrodes in PEM fuel cells

, 2005
This paper presents a one-dimensional model of the PEM fuel cell cathode for analysing current interrupt (CI) measurements. The porous gas diffusion electrode is assumed to consist of a network of dispersed catalyst (Pt/C) forming spherically shaped ...

Design and Performance Evaluation of a PEM Fuel Cell – Lithium Battery–Supercapacitor Hybrid Power Source for Electric Forklifts

International Journal of Electrochemical Science, 2016
In this study, we developed a hybrid power source with a direct current (DC) supply system for electric forklifts. Its designs were based on harsh operating conditions, in line with the requirements for the truck. The power source consists of a fuel cell

Translating whole‐genome doubling into precision medicine in cancer

Molecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

Microscopic Monitoring of Local Temperature in the High Temperature Proton Exchange Membrane Fuel Cell Stack

International Journal of Electrochemical Science, 2013
The non-uniform distributions of internal temperature in a membrane electrode assembly (MEA) of proton exchange membrane fuel cell (PEMFC) stack affect not only the reactions that occur in it, but also its performance and lifetime.
