Thermal responsive Rh1-Pd single-atom catalyst for controlling activity in direct formic acid fuel cells [PDF]

Nature Communications
Single-atom catalysts are highly active for specific reactions; however, their sinter-resistance and clean surfaces make it difficult to impart them with a “smart” property.

A Recent Advance on Partial Evaporating Organic Rankine Cycle: Experimental Results on an Axial Turbine

Energies, 2022
The organic Rankine cycle (ORC) technology is an efficient way to convert low-grade heat from renewable sources or waste heat for power generation. The partial evaporating organic Rankine cycle (PEORC) can be considered as a promising alternative as it ...

Stimuli-Responsive Thiomorpholine Oxide-Derived Polymers with Tailored Hydrophilicity and Hemocompatible Properties

Molecules, 2022
Thermo-responsive hydrophilic polymers, including those showing tuneable lower critical solution temperature (LCST), represent a continuous subject of exploration for a variety of applications, but particularly in nanomedicine.

A Comparison between the Lower Critical Solution Temperature Behavior of Polymers and Biomacromolecules

Physchem, 2022
All-atom molecular dynamics (MD) simulations are employed to compare the lower critical solution temperature (LCST) behaviors of poly(N-isopropylacrylamide) (PNIPAM) and elastin-like polypeptides (ELPs) with the canonical Val-Pro-Gly-Val-Gly ((VPGVG)n ...

Controlling the LCST-Phase Transition in Azobenzene-Functionalized Poly (N-Isopropylacrlyamide) Hydrogels by Light

Gels, 2023
Poly(N-isopropylacrylamide) PNIPAAm hydrogels were modified with a new azobenzene-containing co-monomer. In this work, light responsiveness as an additional functionality, is conceptualized to induce two phase transitions in the same material, which can ...

Machine learning to determine optimal conditions for controlling the size of elastin-based particles

Scientific Reports, 2021
This paper evaluates the aggregation behavior of a potential drug and gene delivery system that combines branched polyethyleneimine (PEI), a positively-charged polyelectrolyte, and elastin-like polypeptide (ELP), a recombinant polymer that exhibits lower

Thermal Conductivity of PNIPAm Hydrogels and Heat Management as Smart Windows

Macromolecular Materials and Engineering, 2023
Though thermoresponsive lower critical solution temperature (LCST) hydrogels have attracted intense attention to be applied in smart windows, less efforts are paid on the LCST effect on the heat transfer process.

Development of a novel micro-bead force spectroscopy approach to measure the ability of a thermo-active polymer to remove bacteria from a corneal model

Scientific Reports, 2021
Microbial keratitis occurs from the infection of the cornea by fungi and or bacteria. It remains one of the most common global causes of irreversible blindness accounting for 3.5% (36 million) of blind people as of 2015.

Design of intrinsically disordered proteins that undergo phase transitions with lower critical solution temperatures

APL Materials, 2021
Many naturally occurring elastomers are intrinsically disordered proteins (IDPs) built up of repeating units, and they can demonstrate two types of thermoresponsive phase behavior.
