Free Phenolic Hydroxyl Groups Govern the Anticancer Activity of α‐Mangostin: A Structure–Activity Relationship Insight

ChemFoodChem, EarlyView.
Free phenolic hydroxyl groups in the chemical structure of the natural xanthone α‐mangostin (MGT) contribute positively to achieving the anticancer profile against murine colon cancer, murine triple negative breast cancer, and human osteosarcoma cancer. ABSTRACT The α‐mangostin (MGT) is a natural xanthone obtained from the pericarp of mangosteen fruit (

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.

A Selectfluor‐based Polonovski Rearrangement Leading to Novel Entities for Synthetic and Medicinal Applications

Chemistry – A European Journal, EarlyView.
Starting from carboxylic acids and Selectfluor‐derivatives, functionalized diazabicyclooctanes can be obtained via a novel Polonovski‐type rearrangement proceeding under mild reaction conditions. Besides their use in organic synthesis the unique structure and reactivity of the rearrangement products enables applications in medicinal chemistry ...

Embedding a Dinuclear Ru─Pt Photocatalyst Into Polyampholytic Graft Copolymer Matrix Enables Prolonged Hydrogen Evolution While Allowing Catalyst Repair

Chemistry – A European Journal, EarlyView.
A unimolecular polyampholytic graft copolymer matrix provides a protective confinement for an electrostatically embedded tetrapyridophenazine‐bridged heterodinuclear Ru‐Pt hydrogen evolving photocatalyst. The matrix slows the degradation kinetics of the catalyst and at the same time does not hinder its repair by ammonium persulfate.

Understanding Consumption of Illicit Drugs and New Psychoactive Substances in Australia by Triangulating Drug Checking and Wastewater‐Based Epidemiology

Drug Testing and Analysis, EarlyView.
First Australian study combining wastewater‐based epidemiology and drug checking, demonstrating how complementary data sources enhance monitoring of illicit drugs and emerging psychoactive substances during high‐use periods. ABSTRACT Consumption of psychotropic drugs is a major economic and public health challenge in Australia.

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).
