Using MIS Thermally Stimulated Currents for Degradation Dependent Energetic Landscape Evaluation in Triple Cation Mixed Halide Perovskites

open access: yesAdvanced Energy Materials, EarlyView.
A state‐of‐the‐art triple cation mixed halide perovskite is characterized using thermally stimulated currents in a MIS device architecture. This enables the separate detection of densities of electron and hole states and their activation energies on the same device, unveiling defect state evolution under the degrading influence of ambient conditions ...

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

open access: yesAngewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Current Status and Challenges of Imaging‐Based Diagnosis of Lymph Node Metastasis in Colon Cancer: The Lymph Node Committee of the Japanese Society for Cancer of the Colon and Rectum

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This review of the status and challenges of diagnosis of lymph node metastasis in colon cancer suggests that it is currently difficult to establish strict criteria for lymph node metastasis, indicating only moderate diagnostic performance. ABSTRACT Background Accurate pre‐treatment evaluation of lymph node metastasis (LNM) in colon cancer is important ...

Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

open access: yesAngewandte Chemie, EarlyView.
Four heavy Hg(II) coordination networks with paramagnetic Fe(II) sites reveal strong and halogen‐tunable low‐frequency (LF) sub‐terahertz phonons and field‐dependent magnetic transitions. LF phonon spectroscopy and Raman magnetospectroscopy are powerful probes of structure, low‐energy vibration, zero‐field splitting, and spin–phonon coupling supported ...
