Exploring Class I polyhydroxyalkanoate synthases with broad substrate specificity for polymerization of structurally diverse monomer units

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Polyhydroxyalkanoate (PHA) synthases (PhaCs) are key enzymes in PHA polymerization. PhaCs with broad substrate specificity are attractive for synthesizing structurally diverse PHAs.

What Do Large Language Models Know About Materials?

open access: yesAdvanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Copolymer-Templated Synthesis of Nitrogen-Doped Mesoporous Carbons for Enhanced Adsorption of Hexavalent Chromium and Uranium

open access: yes, 2018
Polyacrylonitrile (PAN) homopolymer and polyacrylonitrile-block-poly­(n-butyl acrylate) (PAN-b-PBA) block copolymer were synthesized via supplemental activator reducing agent atom transfer radical polymerization and used as precursors to nitrogen-doped ...

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Highly selective and recyclable vanadium‑promoted Mg–Sr–Al oxide catalyst for n‑butanol ethoxylation

open access: yesScientific Reports
2-Butoxyethanol is an important glycol ether widely used as a solvent, wetting agent, emulsifier, and chemical intermediate, and is commonly produced via the ethoxylation of n-butanol with ethylene oxide.

Dacarbazine-Loaded Targeted Polymeric Nanoparticles for Enhancing Malignant Melanoma Therapy

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Dacarbazine (DTIC) dominates chemotherapy for malignant melanoma (MM). However, the hydrophobicity, photosensitivity, instability, and toxicity to normal cells of DTIC limit its efficacy in treating MM.
