Fractionation of sulfur isotopes by Desulfovibrio vulgaris mutants lacking hydrogenases or type I tetraheme cytochrome c3

Frontiers in Microbiology, 2013
The sulfur isotope effect produced by sulfate reducing microbes is commonly used to trace biogeochemical cycles of sulfur and carbon in aquatic and sedimentary environments.

Fundamentals and applications of isotope effect in modern technology [PDF]

Journal of Nuclear Science and Technology Vol 43 No 4 (2006) 375-381, 2008
In this short review I discuss the effect of isotopic mass and isotopic disorder on the properties (vibrational, elastic, thermal and optical) of different crystals.

Dissecting the Mechanisms of a Class of Chemical Glycosylation Using Primary 13C Kinetic Isotope Effects

Nature Chemistry, 2012
Although arguably the most important reaction in glycoscience, chemical glycosylations are among the least well understood of organic chemical reactions, resulting in an unnecessarily high degree of empiricism and a brake on rational development in this ...

Achieving Stable Paired Electrolysis of Captured CO2 and 5‐Hydroxymethylfurfural (HMF) via Tuning Anolyte Composition and Anode Surface

Advanced Functional Materials, EarlyView.
Highly stable paired electrolysis of CO2 and biomass‐derived alcohol (HMF) is achieved by replacing conventional alkaline electrolytes with a tailored triethylamine‐carbonate buffer and anion‐conducting ionomer coatings. This configuration effectively mitigates electrolyte degradation and pH instability typically encountered in alkaline CO2 ...

Influence of multiorbitals and anisotropic Coulomb interactions on isotope effect coefficient in doped Fe-based superconductors [PDF]

, 2016
The present work describes the theoretical analysis of isotope effect coefficient as a function of transition temperature in two orbital per site model Hamiltonian in iron based superconducting system. The expression of isotope effect coefficient has been computed numerically and self-consistently by employing Green's function technique within the BCS ...

Delivery of Islatravir via High Drug‐Load, Long‐acting Microarray Patches for the Prevention or Treatment of Human Immunodeficiency Virus

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Islatravir‐loaded dissolving microarray patches (MAPs) provide a minimally invasive, long‐acting solution for HIV‐1 prevention and treatment. In rats, sustained islatravir delivery lasts up to three months, while in minipigs, efficacious plasma levels are detected for six days.

Functional Biomaterials Derived from Protein Liquid–Liquid Phase Separation and Liquid‐to‐Solid Transition

Advanced Materials, EarlyView.
Protein can undergo liquid–liquid phase separation and liquid‐to‐solid transition to form liquid condensates and solid aggregates. These phase transitions can be influenced by post‐translational modifications, mutations, and various environmental factors.

Adsorption and Separation by Flexible MOFs

Advanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,
