We report a transformative epoxy system with a microalgae-derived bio-binder from hydrothermal liquefaction processing (HTL). The obtained bio-binder not only served as a curing agent for conventional epoxy resin (e.g.

Polymeric hybrid nanocomposites, due to improved mechanical, thermal, and electrical properties, are key factors in recent technologies. Because of anisotropic characteristics of polymeric hybrid nanocomposites, mechanical properties and their behavior are very difficult to predict. If they are fabricated with complicated woven fabric patterns, it becomes more difficult to predict.

Article Synopsis
  • - The study focuses on improving the preparation and quantification of boron nitride nanotubes (BNNTs) from commercial sources to facilitate industrial use and experimental research.
  • - A new method utilizing FTIR analysis allows for the quantification of hexagonal boron nitride (h-BN) in BNNT samples by using a pure h-BN internal standard to enhance measurement accuracy.
  • - The research introduces two BNNT enrichment techniques along with an innovative sonication-assisted filtration process, demonstrating that specific FTIR peak ratios can effectively calibrate and quantify h-BN content in mixed samples, potentially improving the purity of BNNTs for further development.

In the present study experimental and numerical investigations were carried out to predict the low velocity impact response of four symmetric configurations: 10 ply E Glass, 10 ply AS4 Carbon, and two Hybrid combinations with 1 and 2 outer plies of E Glass and 8 and 6 inner plies of Carbon. All numerical investigations were performed using commercial finite element software, LS-DYNA. The test coupons were manufactured using the low cost Heated Vacuum Assisted Resin Transfer Molding (H-VARTM©) technique.

Understanding drug transportation and delivery mechanism from a molecular viewpoint is essential to find better treatment pathways. Despite the fact that many significant drugs such as anticancer doxorubicin and mitoxantrone are predominantly hydrophilic, an efficient methodology to deliver hydrophilic drug components is not well established. Here we explore this problem by studying "patchy" polymeric micelle assisted hydrophilic component transportation across a lipid membrane and delivery inside a biological lipid vesicle.
