CEBPG‐Mediated Palmitic Acid Adaptation of Cancer‐Associated Fibroblasts Drives Metastasis of Oral Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
This study reveals a metabolic signaling axis in the OSCC microenvironment where palmitic acid (PA) drives the activation of CAFs. PA uptake triggers CEBPG‐dependent epigenetic remodeling to upregulate ERN1 and TMBIM6, thereby mitigating ER stress. This adaptive program sustains CAF survival and the pro‐metastatic phenotype, establishing this pathway ...

Formation of Gallium Monofluoride in the Coordination Sphere of Nickel

open access: yesAngewandte Chemie, EarlyView.
The elusive gas‐phase species gallium monofluoride forms selectively in the coordination sphere of a nickel(II) centre as a product of C(sp3)–F bond activation, with a weakly coordinating anion as the fluorine source. The herein reported gallium monofluoride ligand acts as a very strong σ‐donor ligand at nickel and serves as a fluorine donor towards ...

Molybdenite Re-Os Isotopic Dating of Xitian Deposit in Hunan Province and Its Geological Significance

open access: yesYankuang ceshi, 2014
The Xitian large-scale W-Sn polymetallic ore field has been explored in recent years. It is found in jointed adjoining areas of the Nanling and Qinhang metallogenic belts which are located on the boundary between Hunan and Jiangxi provinces, and the junction of the Yangtze and Cathaysia blocks.

From Materials to Medical Images: Translating Perovskite‐Based X‐Ray Detectors Toward Clinical Imaging

open access: yesAdvanced Science, EarlyView.
This review examines perovskite‐based X‐ray detectors from a materials‐to‐medical‐images perspective. Recent progress in perovskite‐based X‐ray detectors is discussed with emphasis on their relevance to clinical imaging. The key barriers to clinical implementation are analyzed.

CO2‐Induced Reverse Lattice Oxygen Spillover on Pt/CeO2 Enables Sulfur‐Resistant Dry Reforming of Methane

open access: yesAngewandte Chemie, EarlyView.
A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

Tracing seawater evaporation and its role in the formation of sediment-hosted stratiform copper deposits

open access: yes, 2014
This study investigates the preserved fluid contents of different generations of mineralised and unmineralised vein minerals from multiple different deposits across the Zambian Copperbelt to define the fluid physicochemical characteristics of the fluids ...

Application of the 190Pt-186Os isotope decay system to dating platinum-group minerals [PDF]

open access: yes, 2010
Constraining the formation age of platinum-group minerals (PGM) in placer deposits has traditionally been very challenging. The 190Pt-186Os decay system, measured by laser ablation multi-collector ICPMS (LA-MC-ICPMS), has been demonstrated as a useful ...
