Ultrasensitive Ion‐Imprinted Detection System with Pore‐Depended Electrochemiluminescence Mechanism for Accurate and Rapid Monitoring of Cesium in the Environment

open access: yesAdvanced Science, EarlyView.
This study focuses on the rapid and accurate determination of cesium, a key radioactive contaminant attracting global attention, by creating an ultrasensitive pore‐dependent electrochemiluminescence detection system. It has been successfully applied in the determination of various kinds of environmental samples, exhibiting its significance in the ...

Radioactivity in returned lunar materials [PDF]

open access: yes
The H-3, Ar-37, and Ar-39 radioactivities were measured at several depths in the large documented lunar rocks 14321 and 15555. The comparison of the Ar-37 activities from similar locations in rocks 12002, 14321, and 15555 gives direct measures of the ...

Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

open access: yesAdvanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

The conversion of L-histidine to glutamic acid by liver enzymes [PDF]

open access: yes, 1952
Edlbacher and Neber (1) showed in 1934 that the liver enzyme named histidase degrades histidine to NH3, formic acid, and an unknown product which on further treatment with strong alkali yields glutamic acid.

Supramolecular Macrocyclic Iodine Adsorbents Enable Photothermally Stable Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Two novel diazapentacene‐based macrocycles are synthesized with expanded cavities that enable dual‐mode iodine adsorption through both physical and chemical interactions. When applied as iodine adsorbents in solar cells, PSCs incorporating M4 achieve 26.13% efficiency with 95.85% retention after 1000 h at 85 °C.

High-affinity binding sites involved in the import of porin into mitochondria [PDF]

open access: yes, 1987
The specific recognition by mitochondria of the precursor of porin and the insertion into the outer membrane were studied with a radiolabeled water-soluble form of porin derived from the mature protein.

Metal–Organic Framework Featuring Monodispersed Silver Cation Sites for Highly Efficient and Selective Extraction of Aqueous Iodide Anions

open access: yesAdvanced Science, EarlyView.
A novel cationic metal–organic framework (MOF‐monoAg) featuring monodispersed silver (Ag+) sites is developed for the highly selective extraction of aqueous iodide ions (I−). MOF‐monoAg exhibits high accessibility, selectivity, and binding affinity toward I− ions, enabling superior iodine extraction from seawater and efficient iodide removal from ...

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Rethinking Sustainable Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This perspective examines sustainability across the entire battery lifecycle, from mining and manufacturing to use and end of life. Twelve principles for ‘green’ batteries are outlined, and it is argued that joint industrial, academic, and policy efforts are essential to building a truly sustainable energy future. Abstract Batteries will play a pivotal
