AI Article Synopsis

  • - Halide perovskite nanocrystals (PNCs) are promising for visible-light photocatalysis due to their high absorption, ability to handle defects, and adjustable band structure, but they struggle with sensitivity to environmental factors like humidity and heat.
  • - The study explores embedding PNCs into polymeric ionic liquids to create composites that improve stability for photocatalytic applications like degrading organic dyes.
  • - The results showed that these embedded PNCs had enhanced resistance to light, moisture, water, and heat for about 200 days, improving their viability in solar-driven processes.

Article Abstract

Halide perovskite nanocrystals (PNCs) have emerged as potential visible-light photocatalysts because of their outstanding intrinsic properties, including high absorption coefficient and tolerance to defects, which reduces non-radiative recombination, and high oxidizing/reducing power coming from their tuneable band structure. Nevertheless, their sensitivity to humidity, light, heat and water represents a great challenge that limits their applications in solar driven photocatalytic applications. Herein, we demonstrate the synergistic potential of embedding PNCs into polymeric ionic liquids () to fabricate suitable composites for photodegradation of organic dyes. In this context, the stability of the PNCs after polymeric encapsulation was enhanced, showing better light, moisture, water and thermal stability compared to pristine PNCs for around 200 days.

Int J Nanomedicine

December 2024

Division of Medical Physics and Biophysics, Gottfried Schatz Research Center for Cell Signaling, Metabolism and Aging, Medical University of Graz, Graz, 8010, Austria.

Background: Selenium (Se) is a vital micronutrient for maintaining homeostasis in the human body. Selenium nanoparticles (SeNPs) have demonstrated improved bioavailability compared to both inorganic and organic forms of Se. Therefore, supplementing with elemental Se in its nano-form is highly promising for biomedical applications related to Se deficiency.

Among the various studies on CO2 utilization, the sustainable and cost-effective fixation of CO2 into cyclic carbonates remains one of the most intriguing subjects. To this end, a novel type of  composite dicationic ionic liquid material, DIL@PDIL, was developed. This composite consists of a dicationic ionic liquid (DIL), DMAP[TMGH]Br, supported on a polymeric dicationic ionic liquid (PDIL), P-DVB/Im[TMGH]Br.

Low field electrocaloric effect at isotropic-ferroelectric nematic phase transition.

Soft Matter

December 2024

Advanced Materials and Liquid Crystal Institute, Kent State University, Kent, OH, 44242, USA.

Electrocaloric effects (ECE) in solid state materials, such as ferroelectric ceramics and ferroelectric polymers, have a great impact in developing cooling systems. Herein, we describe the ECE of a newly synthesized ferroelectric nematic liquid crystal compound at the isotropic-ferroelectric nematic (I-N) phase transition. While the Joule heat completely suppressed the ECE in a DC field, in an AC field with < 1.

Poly(2-Hydroxymethyl-2-oxazoline) as Super-hydrophilic Antifouling Polymer.

Angew Chem Int Ed Engl

December 2024

Ghent University, Department of Organic CHemistry, Krijgslaan 281 S4, 9000, Ghent, BELGIUM.

Non-ionic "super-hydrophilic" polymers generally possess non-fouling characteristics and can suppress non-specific interactions with blood proteins. Here, we revitalized a protected alcohol functionalized 2-oxazoline monomer, 2-acetoxymethyl-2-oxazoline and explored the possibility of making "super-hydrophilic" poly(2-oxazoline)s for biomedical applications. The synthesis of the 2-acetoxymethyl-2-oxazoline monomer and its cationic ring-opening homopolymerization and copolymerization kinetics are reported.

Conjugated polymers (CPs) with polar side chains can conduct electronic and ionic charges simultaneously, making them promising for bioelectronics, electrocatalysis and energy storage. Recent work showed that adding alkyl spacers between CP backbones and polar side chains improved electronic charge carrier mobility, reduced swelling and enhanced stability, without compromising ion transport. However, how alkyl spacers impact polymer backbone conformation and, subsequently, electronic properties remain unclear.
