Angewandte Chemie, EarlyView.A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

How Media Represent Australian Indigenous Business: Comparing Australian and International Coverage
Australian Journal of Social Issues, EarlyView.ABSTRACT Media representations of Indigenous business shape public perceptions, investor confidence and consumer demand, influencing how Indigenous enterprises are valued and understood. This Indigenous‐led study systematically reviews grey literature on Australian Aboriginal and Torres Strait Islander businesses published between 2006 and 2024 ...

A Mesoionic Platform for Persistent Anionic Nitrogen‐Centered Radicals
Angewandte Chemie, EarlyView.Charge did not meet spin: Mesoionic 1,2,3‐triazines undergo reversible one‐electron reduction to persistent anionic nitrogen‐centered radicals. Electron paramagnetic resonance, single‐crystal x‐ray diffraction, and calculations reveal nitrogen‐localized spin and structural reorganization, while crystalline salts show clean redox cycling.

Chirality‐Driven Piezocatalysis in MOFs: Achieving Efficient Cocatalyst‐Free Hydrogen Evolution
Angewandte Chemie, EarlyView.We report a chirality‐driven post‐synthetic modification strategy that grafts chiral L‐histidine (L‐His) onto the Hf6 clusters of MOF‐808(Hf), which significantly boosts the piezoelectricity and charge transfer efficiency, thus significantly enhancing the piezocatalytic performance of MOF‐808(Hf).

Angewandte Chemie, EarlyView.This review highlights an emerging anticancer approach integrating platinum agents into photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) systems, further augmented by cancer cell membrane‐ and organelle‐targeting. By directing photoactivated platinum complexes from nontargeted distribution to cancer cells or defined subcellular sites ...

The Problem of Patent Underdevelopment [PDF]
, 2005 Commentators have long recognized that much of the work of commercializing an invention occurs after a patent is received. They have not recognized, however, that by the time market conditions make commercialization potentially attractive, the remaining ...

Angewandte Chemie, EarlyView.Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.
