Shallow Trap States Induced by Zinc Vacancies in Wurtzite ZnO for Enhanced Charge Separation and Photocatalytic Hydrogen and Oxygen Evolution Reactions

Advanced Energy & Sustainability Research
Hydrothermally synthesized ZnO photocatalysts with controlled cation deficiency were prepared to evaluate the role of Zn‐vacancy engineering in solar water splitting. Pristine ZnO (Zn) and Zn‐deficient ZnO were systematically characterized by structural,

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Impedance Study of Spinel Type Fe-Co3O4 Oxide Thin Film Electrodes in Alkaline Medium

International Journal of Electrochemical Science, 2009
Spinel type Fe-Co3O4 (0, 5 and 10 % of Fe) oxide thin films have been investigated as electrocatalysts for the oxygen evolution reaction (OER) in 1M KOH using electrochemical impedance spectroscopy (EIS) technique.

Evolution of oxygen isotopic composition in the inner solar nebula

, 2005
Changes in the chemical and isotopic composition of the solar nebula with time are reflected in the properties of different constituents that are preserved in chondritic meteorites. CR carbonaceous chondrites are among the most primitive of all chondrite

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Highly Efficient Water Electrolysis Using NaOH–KOH Hydrate Melt

Electrochemistry
To enhance the efficiency of water electrolysis, this study focuses on the NaOH–KOH hydrate melt (NaOH : KOH : H2O = 9 : 61 : 30 mol%) at temperatures ranging from 100 to 200 °C.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.
