Efficient synthesis of Vitamin D3 in a 3D ultraviolet photochemical microreactor fabricated using an ultrafast laser [PDF]

arXiv, 2023
Large-scale, high-precision, and high-transparency microchannels hold great potential for developing high-performance continuous-flow photochemical reactions. We demonstrate ultrafast laser-enabled fabrication of 3D microchannel reactors in ultraviolet (UV) grade fused silica which exhibit high transparency under the illumination of UV light sources of

Preventing Benzoquinone‐Based Catalyst Aggregation Enables the One‐Step Synthesis of Highly Conductive Poly(benzodifurandione) without Post‐Reaction Purification

Advanced Materials, EarlyView.
α‐Tocopherylquinone (α‐TQ), the oxidation product of α‐tocopherol (α‐TOH), catalyzes the oxidative polymerization of 3,7‐dihydrobenzo[1,2‐b:4,5‐b′]difuran‐2,6‐dione (HBFDO). The saturated aliphatic chiral side chain of α‐TQ suppresses its crystallization, enabling high‐conductivity polymer ink without needing post‐polymerization dialysis. This scalable

Structure and dynamics of dynorphin peptide and its receptor [PDF]

arXiv, 2019
Dynorphin is a neuropeptide involved in pain, addiction and mood regulation. It exerts its activity by binding to the kappa opioid receptor (KOP) which belongs to the large family of G-protein coupled receptors. The dynorphin peptide was discovered in 1975, while its receptor was cloned in 1993.

Utilising feed effectors and automated feeders for semi‐intensive pacific white shrimp (Litopenaeus vannamei) production

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 540-551, December 2022., 2022
Abstract Feed effectors have been suggested to improve the efficiency of plant‐based shrimp diets by increasing attractability and palatability. This research trial aimed to expand upon previous Pacific white shrimp (Litopenaeus vannamei) research involving plant‐based diets, feed effectors and passive acoustic monitoring (PAM) in a laboratory setting ...

Fully Passive Electrochemical Oxygen Sensor Enabled With Organic Electrochemical Transistor

Advanced Materials Technologies, EarlyView.
A wireless oxygen sensor that operates with low power without batteries, using organic electrochemical transistors (OECTs) powered by near‐field communication (NFC) is presented. The sensor combines an oxygen‐permeable membrane and a gel electrolyte to detect oxygen in air and complex liquids, making way for sustainable sensor technologies.

Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

Advanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...
