Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

open access: yesAdvanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Enhanced Osteoconductivity of Zirconia Implants with One-Step Femtosecond Laser Treatment Through Morphological and Chemical Modifications

open access: yesJournal of Functional Biomaterials
Improving surface bioactivity is crucial to acquiring zirconia implants with ideal osteoconductivity. In this work, we enhanced the surface properties of zirconia implants, specifically roughness, hydrophilicity, and osteoconductivity, using a “one-step”

Modulation of TRP Channel Activity by Hydroxylation and Its Therapeutic Potential

open access: yesPharmaceuticals, 2017
Two transient receptor potential (TRP) channels—TRPA1 and TRPV3—are post-translationally hydroxylated, resulting in oxygen-dependent regulation of channel activity.

17β-Estradiol hydroxylation catalyzed by human cytochrome P450 1B1

open access: yes, 1996
The 4-hydroxy metabolite of 17β-estradiol (E2) has been implicated in the carcinogenicity of this hormone. Previous studies showed that aryl hydrocarbon-receptor agonists induced a cytochrome P450 that catalyzed the 4- hydroxylation of E2.

Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

open access: yesAdvanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

Iron-functionalized Al-SBA-15 for benzene hydroxylation

open access: yes, 2008
For the first time an ordered mesoporous silica (Fe-Al-SBA-15) with catalytically active isolated Fe surface species for the hydroxylation of benzene with nitrous oxide is prepared by introduction of Fe3+ in the synthesis gel of Al-SBA ...

Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

open access: yesAdvanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.
