Advanced Materials, EarlyView.Defect engineering of ultrathin RuCu alloy nanostructures has been successfully achieved to enhance ammonia electrosynthesis under indutrial‐level current density. Simultaneously, the stable ampere‐level operation of nitrate electroreduction on defective RuCu nanostructures can drive seawater desalination at an ultrafast salt removal rate, offering an ...

Recent Trends in Metabolomics by NMR Spectroscopy
Angewandte Chemie, EarlyView.AI tools were applied to analyze more than 5 000 publications indexed in Scopus (2018–2025), identifying key trends and research directions in NMR‐based metabolomics. The artificial intelligence‐assisted workflow classified papers into six main fields of application, human health, food and nutrition, veterinary science, plants, environment, and ...

BMC Cancer, 2021 Background Cancerous cells can recycle metabolic ammonium for their growth. As this ammonium has a low nitrogen isotope ratio (15N/14N), its recycling may cause cancer tissue to have lower 15N/14N than surrounding healthy tissue. We investigated whether,

, 2013 The 15N isotopologue abundance ratio measured today in different bodies of the solar system is thought to be connected to 15N-fractionation effects that would have occured in the protosolar nebula.

First measurements of 15N fractionation in N2H+ toward high-mass star forming cores [PDF]
, 2015 We report on the first measurements of the isotopic ratio 14N/15N in N2H+ toward a statistically significant sample of high-mass star forming cores. The sources belong to the three main evolutionary categories of the high-mass star formation process ...

Impact of two-bond 15N–15N scalar couplings on 15N transverse relaxation measurements for arginine side chains of proteins [PDF]
Journal of Biomolecular NMR, 2018 NMR relaxation of arginine (Arg) 15Nε nuclei is useful for studying side-chain dynamics of proteins. In this work, we studied the impact of two geminal 15N-15N scalar couplings on measurements of transverse relaxation rates (R 2 ) for Arg side-chain 15Nε nuclei.

QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study
Advanced Science, EarlyView.The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...

Total N difference method and 15N isotope dilution methode - A comparative study on N-fixation [PDF]
, 2002 In the study, the 15N fixation of a number of green manure crops were studied using either the 15N dilution technique, or the simple total N difference method.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Angewandte Chemie, EarlyView.Radiofrequency amplification by stimulated emission of radiation (RASER) of solutes was achieved via parahydrogen‐induced polarization (PHIP) and polarization transfer from the produced hyperpolarization donors to solutes via the intermolecular nuclear Overhauser effect (NOE).
