OER Activity Promoted by Organic Ligand‐Free Cs2Pt(Cl, Br)6 Perovskite Photocatalyst for Solar‐Driven Water Splitting

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study explores Cs2PtX6 (X = Cl, Br) lead‐free perovskites as sustainable photocatalysts for solar‐driven water splitting. Cs2PtBr6 outperforms Cs2PtCl6 in oxygen evolution due to its narrower bandgap and efficient charge carrier dynamics, enabling enhanced light absorption and charge separation.

Comparison of a GC-Orbitrap-MS with Parallel GC-FID Capabilities for Metabolomics of Human Serum

open access: yesbioRxiv, 2019
Gas chromatography mass spectrometry (GC-MS) platforms for use in high throughput and discovery metabolomics have heavily relied on time of flight (ToF), and low resolution quadrupole and ion trap mass spectrometers and are typically run in electron ...

Development of on-line and Field Dual TD-GC-FID/MS for Automatic and Continuous Volatile Organic Compounds (VOCs) Ambient Air and Odour Monitoring

open access: yesChemical Engineering Transactions, 2018
Ambient air is polluted by many Volatile Organic Compounds (VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from ng/m3 up to mg/m3 depending on the location of the measurements.

Essential oils of Mentha pulegium and Mentha rotundifolia from Uruguay

open access: yesBrazilian Archives of Biology and Technology, 2002
Essential oils obtained by hydrodistillation from leaves of Mentha pulegium L. and Mentha rotundifolia (L.) Huds. from Uruguay were analysed by GC-FID and GC-MS. Oxygen-containing monoterpenes were the main group of constituents in both oils.
