Geochemical properties of helium and its origin in the Indus Basin, Pakistan

Journal of Natural Gas Geoscience
The Indus Basin, one of Pakistan's most significant hydrocarbon provinces, is an underexplored region for helium resources. This study investigates the geochemical characteristics of helium in natural gas samples from the Middle and Lower Indus Basins ...

Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

Quantitative Partitioning of Photoautotrophic and Photoheterotrophic Contributions During Mixotrophic Growth of Scenedesmus obliquus

Biotechnology and Bioengineering, EarlyView.
Carbon and oxygen fluxes during photoautotrophic, photoheterotrophic and mixotrophic growth of Scenedesmus obliquus. ABSTRACT Mixotrophic growth of microalgae involves the simultaneous assimilation of inorganic and organic carbon sources, but the quantitative contributions of photoautotrophic and photoheterotrophic metabolisms remain poorly resolved ...

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

Carbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

B, N‐Co Doped Porous Carbon Nanotubes Supported Cu Single Atoms and B‐Doped Cu Nanoparticles for High‐Performance Electrocatalytic NO3RR and Zn‐Nitrate Batteries

Carbon Energy, EarlyView.
The ToC image shows a porous B, N‐doped carbon nanotube decorated with B‐doped Cu nanoparticles for nitrate‐to‐ammonia conversion. The unique structure enhances charge transport, promotes the adsorption and activation of key intermediates, alters the rate‐determining step, suppresses hydrogen evolution, and improves NH3 yield and Faradaic efficiency ...

Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Isotopic Dilution Provides No Evidence for Cu2+-Bridged β-Amyloid Homo-Oligomers

The oligomerization of many peptides is known to be influenced by the binding of transition metal ions, with intermolecular metal–ion bridges being one possible mechanism. In the case of copper ions, it is possible to identify Cu 2+

One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

Chemistry – A European Journal, EarlyView.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.
