Hydrogen Bonding in Graphene

Small, EarlyView.
The hydrogen concentration and binding energies in large area graphene are determined from effusion measurements. The samples are grown using chemical vapor deposition using deuterated methane and deuterium as readily identifiable isotopes. Total hydrogen concentrations of 1.2 ‐ 6.9 × 1013 cm−2 are obtained.

Ligand‐Controlled Tunable Distal C(sp2)–H Functionalization of Aryl and Benzyl Phosphonates

Transformative Chemistry, EarlyView.
The switchable borylation of aryl and benzyl phosphonates with good to excellent regioselectivity was demonstrated. Through orthogonal transformation of Horner–Wadsworth–Emmons olefination and Suzuki–Miyaura cross coupling, a variety of styrene derivatives were obtained with precise site control.

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

More π, less Gap: Band Gap Tuning in Hybrid Antimony Halide Charge Transfer Semiconductors

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Extending the π‐conjugation of the organic cation from bipyridinium to phenanthrolinium in hybrid antimony chloride charge transfer semiconductors reduces the band gap from 2.6 to 2.1 eV. This demonstrates that modifying the organic cation's π‐system enables band gap tuning in hybrid charge transfer semiconductors.

Design and commissioning of a new synchrotron beamline dedicated to X‐ray footprinting mass spectrometry

Journal of Synchrotron Radiation, EarlyView.
A dedicated beamline at the Advanced Light Source synchrotron has been opened and commissioned for X‐ray footprinting mass spectrometry.The structural biology method of X‐ray footprinting mass spectrometry (XFMS) is available at two national synchrotron beamlines in the USA: one at the Advanced Light Source (ALS) on the West Coast and the other at the ...

Mapping Allergen B‐ and T‐Cell Epitopes: Technological Advances and Their Role in Precision Allergy Therapy

Allergy, EarlyView.
ABSTRACT Allergic diseases arise from aberrant immune recognition of otherwise harmless environmental proteins and are driven by epitope‐specific interactions between allergens and the adaptive immune system. Although component‐resolved diagnostics have improved molecular characterisation of sensitization, they remain limited to whole‐allergen ...

Energetic stress in combination with impaired fatty acid oxidation induces sequestration of CoA and adaptation of CoA metabolism

The FEBS Journal, EarlyView.
Computational modelling and in vitro liver cell experiments indicate that medium‐chain acyl‐CoA dehydrogenase (MCAD) deficiency causes an accumulation of (especially medium‐chain) acyl‐CoAs at the cost of free CoA (CoASH). A substantial decrease in CoASH impairs flux through many pathways essential for energy homeostasis.

Tyrosine residues at the substrate binding site in human NQO1 homodimer: Protein conformational dynamics and optimization of substrate binding geometry

The FEBS Journal, EarlyView.
Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...
