Accelerating Wound Healing with Combinatorial Therapy Using Natural Melanin Nanoparticle‐Polyvinyl Alcohol Blend and Core‐Sheath Hybrid Nanofibers under UV‐A Irradiation

  •  15 February 2024

Graphical Abstract

Description unavailable

Nanoparticle-nanofiber hybrid systems comprised of melanin nanoparticles (MNPs) and polyvinyl alcohol (PVA), are fabricated through co-electrospinning, and demonstrate potent antibacterial effects using photodynamic therapy. Upon exposure to UV-A radiation, MNP-PVA blend and core-sheath nanofibers exhibits antibacterial activity against E. coli. These nanofibers accelerate wound healing in L929 scratch assays, with UV-A irradiation enhancing wound closure in MNP-PVA core-sheath nanofibers.

Polypyrrole Modified Granular Activated Carbon Nanocomposite for Treatment of Wastewater Containing Highly Toxic Hexavalent Chromium

  •  15 February 2024

Graphical Abstract

Description unavailable

The polypyrrole (PPy) based granular activated carbon (GAC) nanocomposite adsorbent (P-mePPy GAC) is synthesized via an electro-spraying assisted coating technique of the microemulsion polymerized nanoparticles (mePPy NPs) onto one opposite polarity pre-charged GAC particles surface side. The prepared nanocomposites are investigated for Cr(VI) adsorption, and the results indicate excellent improvement in Cr(VI) adsorption by combining mePPy and GAC.

One‐Step Solvent‐Free Synthesis of Dimer Diamine‐Based Autocatalytic Polyol for the Preparation of Polyurethane Foams

  •  15 February 2024

Graphical Abstract

Description unavailable

A dimer diamine-based autocatalytic polyol (TETRAOL) is synthesized with 100% atom economy. TETRAOL is synthesized in a one-pot and one-step reaction. Bio-based foams are prepared by using TETRAOL and vegetable oil-based polyols. Polyurethane foams display good thermal and mechanical properties.

3D Printable Self‐Sensing Magnetorheological Elastomer

  •  15 February 2024

Graphical Abstract

Description unavailable

Front cover: Self-sensing magnetorheological elastomers showcase resistive changes induced both by magnetic fields and mechanical loads, on top of magnetic-dependent stiffening. In article 2300294, Leone Costi and co-workers report the first case of 3D printable self-sensing magnetorheological elastomers. The proposed materials are characterized both as a function of a varying magnetic field and mechanical cyclic load, both in compression and tension.

Super-Elastic and Dimensionally Stable Polyether Block Amide Foams Fabricated by Microcellular Foaming with CO2&N2 as Co-Blowing Agents

  •  14 February 2024

Graphical Abstract

Description unavailable

Microcellular foaming with CO2 and N2 as co-blowing agents is developed to achieve mechanically robust PEBA foams by reducing the dimensional shrinkage. Compared with pure CO2 as blowing agents, the co-blowing agents leads to significantly reduced shrinkage of PEBA foams after foaming and hence improved mechanical performance. The promising outcome paves way for developing high-performance thermoplastic elastomer foams.

Stereolithography as a 3D printing technique for fabricating polymer nanocomposites is reviewed. Focus is given on variations of the technique, material preparation prior to printing, chemistry during printing, and current and potential applications of the technology.

Advances in Piezoelectric Polymer Composites for Energy Harvesting Applications: A Systematic Review

  •  27 November 2018

Graphical Abstract

Description unavailable

The versatility of different piezoelectric materials for energy harvesting applications is explored throughout this review while giving special attention to piezoelectric polymers and composites. It has been revealed that these materials could be a better alternative to piezo-ceramics, in terms of mechanical flexibility, suitable voltage with sufficient power output, lower manufacturing cost, and rapid processing.

A Review: Natural Fiber Composites Selection in View of Mechanical, Light Weight, and Economic Properties

  •  10-24
  •  2 September 2014

Graphical Abstract

Description unavailable

Due to light weight, low cost, and reasonable strength, natural fiber are replacing synthetic fibers and because of these properties their applications in automobile industries were increased. Comparisons of material indices are made to investigate the possibility to use natural fiber composites instead of some conventional and non-conventional materials for beam and panel structures.
