Catalyst‐Controlled Divergent Strain‐Release Amination and Skeletal Remodeling of Bicyclo[1.1.0]Butanes

open access: yesAngewandte Chemie, EarlyView.
Catalyst‐controlled nitrene transfer unlocks divergent reactivity of bicyclo[1.1.0]butanes. Rhodium catalysis promotes selective strain‐release amination to access cyclobutene and cyclobutane amino‐acid scaffolds, whereas visible‐light photocatalysis redirects nitrene reactivity toward double amination and skeletal remodeling, providing a complementary

Alcohol and Other Drug Vocational Education and Training in Australia: Changes in the Landscape From 2011 to 2024

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT People impacted by alcohol and other drugs (AOD) are supported across a range of health and social service settings, often by workers in generalist roles who may not have specialist training. Vocational education and training (VET) plays a key role in equipping AOD workers with the knowledge and skills required for practice, yet there is no ...

Engineering Atomically Precise Cu4I4 Nanoclusters With Integrated Adsorption and Hydrogenation Functions for Efficient Photocatalytic Nitrate‐to‐Ammonia Conversion

open access: yesAngewandte Chemie, EarlyView.
Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

open access: yesAngewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

open access: yesAngewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
