Nonthermal Plasma Technology as a Versatile Strategy for Polymeric Biomaterials Surface Modification: A Review [PDF]

, 2009
In modern technology, there is a constant need to solve very complex problems and to fine-tune existing solutions. This is definitely the case in modern medicine with emerging fields such as regenerative medicine and tissue engineering.

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Engineering of Hybrid SiO₂@{N-P-Fe} Catalysts with Double-Ligand for Efficient H₂ Production from HCOOH

Energies
Two Fe-based hybrids, [SiO2@NP(Ph)2/FeII/PP3] and [SiO2@NP(t-Bu)2/FeII/PP3], were synthesized using the double-ligand approach by covalently grafting NP ligands onto the surface of SiO2.

Need for mechanically and ergonomically enhanced tremor-suppression orthoses for the upper limb: a systematic review

Journal of NeuroEngineering and Rehabilitation, 2019
Introduction Tremor is the most common movement disorder, affecting 5.6% of the population with Parkinson’s disease or essential tremor over the age of 65. Conventionally, tremor diseases like Parkinson’s are treated with medication.

Bioinspired Bromination Enables Extensible, Strain‐Stiffening Resilin Peptide Scaffolds with Tunable Degradation

Advanced Functional Materials, EarlyView.
Bioinspired bromination of a resilin‐derived peptide enables the fabrication of electrospun nanofibrous scaffolds that uniquely combine strain‐stiffening elasticity, proteolytic stability, and antioxidant functionality. These brominated peptide–gelatin hybrids mimic the extensibility of natural elastomers, demonstrating tunable mechanical resilience ...

Tuning the viscoelastic properties of peptide coacervates by single amino acid mutations and salt kosmotropicity

Communications Chemistry
Coacervation, or liquid-liquid phase separation (LLPS) of biomacromolecules, is increasingly recognized to play an important role both intracellularly and in the extracellular space. Central questions that remain to be addressed are the links between the

Double-Ligand [Fe/PNP/PP₃] and Their Hybrids [Fe/SiO₂@PNP/PP₃] as Catalysts for H₂-Production from HCOOH

Energies
Two types of iron-based catalysts, [Fe/SiO2@iProPNP/PP3] and [Fe/SiO2@tBuPNP/PP3], for the dehydrogenation of formic acid (FADH), were synthesized. These catalysts were developed using a double-ligand approach combining a PNP ligand and a PP3 ligand ...

Role of Lipopolysaccharide in Protecting OmpT from Autoproteolysis during In Vitro Refolding

Biomolecules, 2020
Outer membrane protease (OmpT) is a 33.5 kDa aspartyl protease that cleaves at dibasic sites and is thought to function as a defense mechanism for E. coli against cationic antimicrobial peptides secreted by the host immune system.
