Regenerative antibacterial hydrogels from medicinal molecule for diabetic wound repair.

Hydrogel products for chronic diabetic wounds, a serious and prevalent complication of diabetes, show limited effects on disability and remain nonspecific. Thus, improvements in the usage of pharmaceutical molecule in the hydrogels are highly desirable to increase the therapeutic effect of hydrogels. In this study, thioctic acid (a common medicine molecule in diabetes treatment) is used for preparing regenerative antibacterial hydrogels (RAH) which contains synthesized silver nanoparticles (AgNPs).

Wide-Temperature Flexible Supercapacitor from an Organohydrogel Electrolyte and Its Combined Electrode.

Hydrogel-based flexible supercapacitors possess the merits of highly ionic conductivity and superior power density, but the existence of water limits their application in extreme temperature scenarios. Noticeably, it is a challenge for people to design more extremely temperature adaptable systems for flexible supercapacitors based on hydrogels with a wide temperature region. In this work, a wide-temperature flexible supercapacitor that can operate at -20-80 °C was fabricated by an organohydrogel electrolyte and its combined electrode (also known as an electrode/electrolyte composite).

"Water-in-Deep Eutectic Solvent" Gel Electrolytes Synergistically Controlled by Solvation Regulation and Gelation Strategies for Flexible Electronic Devices.

Recent developments in flexible electronics have heightened the need for electrolytes with high safety, ionic conductivity, and electrochemical stability. However, neither conventional organic electrolytes nor aqueous electrolytes can meet the above requirements simultaneously. Herein, a novel "water-in-deep eutectic solvent" gel (WIDG) electrolyte synergistically controlled by the solvation regulation and gelation strategies is reported.

Extreme-environment-adapted eutectogel mediated by heterostructure for epidermic sensor and underwater communication.

In recent years, gel-based ion conductor has been widely considered in wearable electronics because of the favorable flexibility and conductivity. However, it is of vital importance, yet rather challenging to adapt the gel for underwater and dry conditions. Herein, an anti-swelling and anti-drying, intrinsic conductor eutectogel is designed via a one-step radical polymerization of acrylic acid and 2, 2, 2‑trifluoroethyl methacrylate in binary deep eutectic solvents (DESs) medium.

Hydrogels as the plant culture substrates: A review.

A class of hydrophilic polymers known as "hydrogels" have extensive water content and three-dimensional crosslinked networks. Since the old period, they have been utilized as plant culture substrates to get around the drawbacks of hydroponics and soil. Numerous hydrogels, particularly polysaccharides with exceptional stability, high clarity, and low cost can be employed as plant substrates.

Oxidation stability enhanced MXene-based porous materials derived from water-in-ionic liquid Pickering emulsions for wearable piezoresistive sensor and oil/water separation applications.

Hypothesis: Stemming from their unique superiorities, TiC-MXenes have emerged as versatile 2D materials for a myriad of appealing applications. However, two crucial issues are detrimental to maximize the inherent properties of MXenes for further specific developments, i.e.

Ultra-Sensitive and Ultra-Stretchable Strain Sensors Based on Emulsion Gels with Broad Operating Temperature.

Hydrogels with mechanical elasticity and conductivity are ideal materials in wearable devices. However, traditional hydrogels are fragile upon mechanical loading and lose functions in climate change because the internal water undergoes freeze and dehydration. Herein, we synthesize stable emulsions at high and low temperatures by introducing glycerol into the W/W emulsions.

Antiswelling and Durable Adhesion Biodegradable Hydrogels for Tissue Repairs and Strain Sensors.

Adhesive hydrogels have gained great interest for biomedical applications, because of their great adhesion, tunable structure, high water content, and biocompatibility. However, it is still challenging to engineer hydrogel materials combining tissue repairs and strain sensors. In this work, poly(thioctic acid) (PTA) is used as a skeleton structure and mixed with polydopamine (PDA), resulting in hydrogels with excellent stretchability, resilience, and adhesion, which can adhere to various organic (porcine skin) and inorganic materials (ceramic, wood, glass, etc.

Ionic-surfactants-based thermotropic liquid crystals.

Thermotropic liquid crystals (TLCs) are a series of soft materials with ordered arrangements of repeating structural units in a certain range of temperature. Specifically, the TLCs constructed by the electrostatic combination between ionic surfactants and other oppositely charged groups have received great attention in the field of optoelectronic devices, material transportation and separation, smart materials as well as biosensing. As typical amphiphilic molecules, ionic surfactants with charged head-groups and long alkyl tails exhibit unique self-assembly behaviors, being preferable as flexible building blocks of TLCs.

Functional polyaspartic acid derivatives as eco-friendly corrosion inhibitors for mild steel in 0.5 M HSO solution.

To improve the corrosion inhibition efficiency of eco-friendly polyaspartic acid (PASP) for mild steel in acidic solutions, PASP/-(3-aminopropyl)imidazole (PD-1) and PASP/-(3-aminopropyl)-imidazole--dodecylamine (PD-2) were chemically synthesized by the facile ring-opening reaction of polysuccinimide. Inhibition efficiencies of PD-1 and PD-2 for mild steel in a 0.5 M HSO solution were investigated by electrochemical measurements (electrochemical impedance and polarization) and the weight loss method.
