Covalent Organic Framework Colloids With Core‐Shell Donor/Acceptor Architecture and Ultralong‐Lived Charge‐Separated States

open access: yesAngewandte Chemie, EarlyView.
Uniform core‐shell colloidal particles of Covalent Organic Frameworks (COFs) are synthesized by a seeded growth of electron‐acceptor COF shells on electron‐donor COF cores. The resulting p‐n heterojunction enables efficient separation of photogenerated charges, which persist for minutes. These core‐shell COFs show efficient CO2 photoreduction to CO and

Cancer‐Associated BCL‐2 Mutants Reveal Mechanisms Towards Venetoclax Resistance

open access: yesAdvanced Science, EarlyView.
Venetoclax (VEN) resistance in chronic lymphocytic leukemia arises from diverse BCL2 mutations. We map mechanisms contributing to VEN resistance across common BCL‐2 variants. G101V and D103Y reduce drug binding and increase sequestration of pro‐apoptotic proteins. V156D blocks VEN allosterically.

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

open access: yesAngewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Japan's security policy, the US-Japan alliance, and the 'war on terror': incrementalism confirmed or radical leap? [PDF]

open access: yes, 2004
Japan's response to the 'war on terror', in the form of the despatch of the JSDF to the Indian Ocean and Iraq, has given policy-makers and academic analysts grounds for believing that Japan is becoming a more assertive military power in support of its US

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

open access: yesAdvanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Conformation‐Selective Binding Domains of Intramolecular Chemically Induced Protein Dimerisation Systems

open access: yesAngewandte Chemie, EarlyView.
Intramolecular chemically induced dimerisation transforms FK506‐ and cyclosporine A‐responsive protein pairs into high‐affinity pseudo‐allosteric switches. Holo‐selective binders isolated by mRNA display convert these switches into gain‐of‐signal biosensors and ultrasensitive ELISAs, enabling direct quantification of both immunosuppressants in ...

The Image of Germany on the Pages of the Newspaper “Russian Invalid” in the First Years of the World War I (1914-1915)

open access: yesЖурнал Фронтирных Исследований
The article analyzes the image of Germany, which was formed by the journalists of the domestic daily newspaper “Russian invalid” in 1914–1915, when the Russian Empire was in active military confrontation with the states of the Triple (later Quadruple ...
