Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

open access: yesRiver, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Nanoscale Ripples at the Surface of SrTiO3 Irradiated by a Broad Low‐Energy Ar+ (7 keV) Ion Beam

open access: yesSmall, EarlyView.
Broad Ar ion beam irradiation creates self‐organized ripple nanostructures on oxide surfaces. A schematic illustrates the process, while cross‐sectional STEM imaging captures the ripple morphology. Complementary elemental mapping by EELS highlights nanoscale chemical variations, linking ion‐beam nanostructuring with structural and compositional ...

Mesoporous Silica Nanoparticles‐Based Formulations for Enhanced Oral Delivery of Peptide Drugs: A Case Study on Insulin

open access: yesSmall, EarlyView.
This work explores the tailored functionalization of mesoporous silica nanoparticles (MSN) to improve the oral delivery of insulin, as a case study. Insulin confinement within silica mesopores increased drug solubility, and co‐formulation with succinylated β‐lactoglobulin yielded pH‐responsive tablets that limited gastric release and proteolysis, while
