A pH‐Responsive Biomimetic Antioxidant Nanoplatform with Dual Renal Targeting for Synergistic Therapy of Acute Kidney Injury

Advanced Science, EarlyView.
A biomimetic nanoplatform (CeAst@MK) is engineered for precise therapy of acute kidney injury by integrating cerium‐based antioxidation, natural flavonoid astragalin, and macrophage membrane camouflage. Featuring kidney‐targeted and pH‐responsive release, CeAst@MK scavenges ROS, suppresses inflammation, and restores renal function via modulation of ...

Hybridization of Homogeneous and Heterogeneous Catalysis to Develop a Novel Biocatalyst via Immobilization of Lipase on Surface Modified Mesoporous Silica Towards Biodiesel Synthesis Application

Advanced Energy and Sustainability Research, EarlyView.
The 3‐(methacryloyloxy)propyltrimethoxysilane surface functionalized SBA‐15 (MP‐SBA‐15) is used for the first time as a lipase carrier. The immobilized CAL‐B exhibits high thermal stability and superior catalytic activity. CAL‐B/SBA‐15 suggests that optimum hydrophobicity gives better catalytic activity.

SSZ‐13‐Zeolith mit Isolierten Co2+‐Zentren als ein Effizientes und Beständiges Katalysatorsystem für die Nichtoxidative Ethandehydrierung

Angewandte Chemie, EarlyView.
Für die nichtoxidative Ethandehydrierung zu Ethen wurden Katalysatoren mit isolierten Co2+‐Spezies in den 6MR‐ (Co2+‐Z2) und 8MR‐Fenstern ([Co(OH)]+‐Z) eines SSZ‐13‐Zeolithen hergestellt. Die Co2+‐Z2‐Spezies zeigten im Vergleich zu den [Co(OH)]+‐Spezies eine unerwartet hohe Ethenbildungsgeschwindikeit.

SSZ‐13 Zeolite with Isolated Co2+ Sites as an Efficient and Durable Catalyst System for Non‐Oxidative Ethane Dehydrogenation

Angewandte Chemie International Edition, EarlyView.
Catalysts with the isolated Co2+ species in the 6MR (Co2+─Z2) and 8MR ([Co(OH)]+─Z) windows of the SSZ‐13 zeolite were synthesized for non‐oxidative ethane dehydrogenation to ethene. The Co2+─Z2 species demonstrate an unexpectedly high rate of ethene formation in comparison with the ([Co(OH)]+─Z species.

Conversion of Cr(VI) to Cr(III) in Water Using Amino-Modified Ordered Mesoporous Silicas: Influence of the Functional Group Architecture

Applied Sciences
Two nitrogen-modified mesoporous MCM-41-type silicas were synthesized by the sol–gel route and post-grafting surface modification procedure, obtaining an aminopropyl-modified MCM-41 (denoted MCM-41-N) and an aminoethyl-aminopropyl-modified MCM-41 ...

CO2 Adsorption on Mesoporous Silica Using Response Surface Methodology (RSM)

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The aim of the current study is to investigate the CO2 adsorption on the mesoporous silica. The adsorbent was characterized by XRD, TEM, SEM, and N2 adsorption desorption. The adsorption isotherms of carbon dioxide (CO2) on the silica were investigated using a static volumetric method at various temperatures.
