Photochemical Patterning and Characterization of Mechanical Properties on Soft Materials
Advanced Functional Materials, Volume 35, Issue 13, March 25, 2025.In this work, the syntheses of two photo‐sensitive and thermoresponsive hydrogel systems, a photo‐stiffening and a photo‐softening hydrogel, are reported. Their potential for fabricating soft materials with patterned mechanical properties is then demonstrated by fabricating an actuator whose higher‐order bending properties can be switched on with light,

Catalytic enantioselective addition of organometallics to unprotected carboxylic acids
Nature Communications, 2019 Unprotected carboxylic acids are classically deemed to be unsusceptible to conjugated additions due to acid-base neutralization. Here, the authors show that the use of an appropriate Lewis acid allows the catalytic addition of organometallics to ...

The effects of carboxylic acids in aluminum anodizing [PDF]
, 2017 Hard-anodized alumina coatings were formed in sulfuric acid at low temperature and high current density in the presence of carboxylic acid additives. Citric acid, trimesic acid, mellitic acid and ethylenediaminetetraacetic acid (EDTA) were utilized in ...

Advanced Functional Materials, EarlyView.A series of ultraviolet‐ and near‐infrared radiation sensitive photoactivatable hydrogels are developed that can be controlled spatiotemporally down to µm precisions using one‐ and two‐photon uncaging. The latent hydroxylamine‐, hydrazine‐, and amine uncaged moieties are used to photopattern a series of diverse proteins displaying complimentary ...
