Photocatalytic reduction of CO2 over Ti3+ self-doped TiO2-based nanomaterials

Journal of CO2 Utilization
In this study, we explored the photocatalytic efficacy of Ti3+-doped TiO2-based photocatalysts for CO2 reduction. The Ti3+ self-doped photocatalysts were synthesized using a straightforward chemical reduction with sodium borohydride (NaBH4).

Linearly polarized, Q-switched Er-doped fiber laser based on reduced graphene oxide saturable absorber

, 2012
We demonstrate generation of linearly polarized pulses from a passively Q-switched Erbium-doped fiber laser. The cavity was designed using only polarization maintaining (PM) fibers and components, resulting in linearly polarized output beam with degree ...

Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

Journal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.

Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

Journal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids

Lipids, EarlyView.
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

Macromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

Bio‐Based Microfluidics With Snail Slime: A By‐Product of Agriculture Plays an Exciting Role in the Chemistry of Microfluidic Reaction Chambers

Macromolecular Rapid Communications, EarlyView.
Due to a broad spectrum of active ingredients, snail slime presents a variety of exciting physical properties and chemical reactivities. Especially in the role of the reduction‐ and stabilizing agent for the manufacturing of gold nanoparticles, its great potential is revealed. Utilising the proteins found in slime, Nanoparticle‐comprising hydrogels are
