Laser scribed proton exchange membranes for enhanced fuel cell performance and stability.
Nat Commun

Department of Chemical Engineering, Electrochemical Innovation Lab, University College London, London, UK.
High-temperature proton exchange membrane fuel cells (HT-PEMFCs) offer solutions to challenges intrinsic to low-temperature PEMFCs, such as complex water management, fuel inflexibility, and thermal integration. However, they are hindered by phosphoric acid (PA) leaching and catalyst migration, which destabilize the critical three-phase interface within the membrane electrode assembly (MEA). This study presents an innovative approach to enhance HT-PEMFC performance through membrane modification using picosecond laser scribing, which optimises the three-phase interface by forming a graphene-like structure that mitigates PA leaching.

Background: Ceramic endosseous implant coatings have gained esteem due to their favorable osteoinductive and osteoconductive properties. However, such a layer may be prone to failure under in vivo conditions, which necessitates its modification.
Objectives: The aim of the present study was to modify an electrodeposited hydroxyapatite (HA) coating on titanium (Ti) with ultrashort-pulsed lasers for the incorporation of the ceramic into the sample surface and the texturing of the metal surface.
Analysis of Cell Dielectrophoretic Properties Using Isomotive Creek-Gap Electrode Device.

Various types of dielectrophoresis (DEP) cell separation devices using AC electric fields have been proposed and developed. However, its capability is still limited by a lack of quantitative characterization of the relationship between frequency and force. In the present study, this limitation was addressed by developing a method capable of fast and accurate quantification of the dielectric properties of biological cells.

Article Synopsis
- - Raman-activated cell sorting (RACS) is a technique that allows for the isolation of single cells without damaging them and without using labels, but its speed is limited due to a low level of spontaneous Raman scattering.
- - The new method, Stimulated Raman-activated cell ejection (S-RACE), combines stimulated Raman imaging with microfluidics to enable high-throughput sorting of single cells based on their unique Raman signatures, achieving a sorting speed of approximately 13 cells per second.
- - S-RACE is effective for sorting various cell types, including live bacteria and lipid-rich cells, and it is also compatible with tissue samples, with real-time feedback control that enhances the sorting process.
Introduction: Cyanobacterium Arthrospira platensis (AP) (Nordstedt) Gomont contains high content of phycobiliproteins (PBP), which are an important source for food industry. Methods effectively extracting proteins contained in AP cells are demanded to provide a supply of the material. Water-based extraction methods are advisable due to the high solubility of the PBP.
