Diffusion based separation methods : Dry distillation of zinc, cadmium and mercury isotopes from irradiated targets

open access: yes, 1997
Diffusion-based separation methods allow the extraction of produced radionuclides with a low loss of target material, which is of special importance when enriched target material is used.

Seasonally resolved growth of freshwater bivalves determined by oxygen and carbon isotope shell chemistry [PDF]

open access: yes, 2010
By means of a monitoring experiment in two rivers in the Netherlands, we establish a relationship between seasonally resolved growth rates in unionid freshwater bivalves and their environment.

Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

open access: yesAdvanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.

YTHDC1 Orchestrates Glucose and Glutamate Rewiring to Overcome Lethal Metabolic Stress in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
Lai et al. find that m6A reader YTHDC1 is specifically overexpressed in triple‐negative breast cancer (TNBC) and orchestrates glucose and glutamine metabolism in an m6A‐dependent manner to confer robust adaptability to lethal metabolic stress. Leveraging YTHDC1 knockdown‐induced metabolic vulnerability, an ATF4 mRNA‐targeted nanotherapy is developed to

Ultrahigh Interfacial Thermal Conductance across GaN/BAs Interfaces via Atomic‐Level Engineering

open access: yesAdvanced Science, EarlyView.
The integration of gallium nitride (GaN) with ultrahigh‐thermal‐conductivity boron arsenide (BAs) substrates represents a promising pathway for developing next‐generation high‐power devices. The heat dissipation capability of such integrated systems is fundamentally governed by thermal transport across GaN/BAs interfaces, and buffer layers such as ...

Precisely Control Relationship between Sulfur Vacancy and H Absorption for Boosting Hydrogen Evolution Reaction

open access: yesNano-Micro Letters
Highlights The Ar plasma etching strategy was introduced to homogeneously distributed S-vacancies (VS) into the NiS2 nanosheets (NiS2-VS). Build the relationship between sulfur vacancy and H absorption and find that NiS2-VS 5.9% performs outstanding ...

Kinetic and thermodynamic parameters of

open access: yesNuclear Engineering and Technology
Mesoporous γ-Al 2 O 3 nanoparticles were synthesized via isoamyl alcohol-assisted controlled precipitation and characterized using XRD, FTIR, N 2 physisorption, SEM, TEM, and DLS. The nanoparticles exhibited a BET specific surface area of 107.6 m 2  g −1

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

Targeting the KAT7/H3K14ac/RAC2 Axis Mediates OXPHOS to Promote Stemness Maintenance and Malignancy in Glioblastoma

open access: yesAdvanced Science, EarlyView.
SOX2 upregulates KAT7 in glioma stem cells, where KAT7 deposits H3K14 acetylation at the RAC2 promoter to activate RAC2 transcription. RAC2‐GTP subsequently promotes PAK1/2/3 phosphorylation, increasing tricarboxylic acid cycle flux and mitochondrial respiration to support glioblastoma malignancy.
