Optimizing TiO2 Nanorods Synthesis for High‐Performance Dye‐Sensitized Solar Cells: An Experimental Study on Time‐Dependent Growth and Characterization

ChemPhotoChem, Volume 10, Issue 2, February 2026.
This study optimizes the hydrothermal synthesis of TiO2 nanorods on FTO substrates, varying the reaction time from 4 to 9 hr. The 8‐h sample (FTO/TiO2 NRs/ hibiscus flower dye/electrolyte/gold/FTO) exhibits optimal alignment and enhanced light absorption, leading to the highest dye‐sensitized solar cells efficiency (η = 0.97%) using hibiscus flower dye.

Integrated multi‐omics analysis reveals metabolic reprogramming as a key driver of angiotensin II‐induced vascular remodeling

VIEW, Volume 7, Issue 1, February 2026.
This study investigates the molecular alterations underlying angiotensin II (Ang II)‐induced vascular remodeling in cardiovascular diseases using a multi‐omics approach. Through data exploration and integrated multi‐omics analysis, our findings reveal that Ang II‐driven vascular injury in vascular smooth muscle cells is mediated by metabolic ...

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

Alterations in Gut Microbiota and Metabolism in Cirrhotic Portal Hypertension: Implications for Disease Progression

Alimentary Pharmacology &Therapeutics, Volume 63, Issue 4, Page 538-556, February 2026.
In‐depth multiomics analyses revealed that the gut microbiota in patients with CPH is dysbiotic. Altered gut microbiota plays an important role in the progression of CPH and affects the host's arginine metabolism to promote arginine biosynthesis. The pro‐inflammatory effects of certain gut bacteria induce iNOS expression, which together act on the ...

Understanding Atrial Fibrillation Complexity Through the Lens of Turbulence Dynamics: Implications for Treatment Strategies

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 2, Page 400-412, February 2026.
ABSTRACT Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. Its incidence increases significantly with age and has become a major global public health issue. Although research into the mechanisms of AF has spanned over a century‐ranging from the reentry theory to the rotor hypothesis‐none of these
