Piezoelectric Nanoparticles Loaded with Curcumin for Cancer Treatment
Abstract: Conventional cancer chemotherapy treatments are often compromised by systemic toxicity which starts from the lack of tumor specificity of administered anticancer drugs. The side effects limit the dose of the drug that can be administrated, making effective cancer treatment difficult. Nanoparticle-based drug delivery has the potential to overcome this challenge by targeted delivery to tumor and taking the advantage of tumor’s natural leaky vasculature to increase the accumulation of drug-loaded …

Study of Nanoindentation Characteristics of Al/B4C/CNT Composites
Abstract: Nanoindentation characterization is one of the essentialities that are used in current work to measure hardness and elastic moduli properties of Al reinforced with B4C particulates and carbon nano-tube (CNT). The nanoindentation characterization enables measurements of mechanical characteristics on nano scale. The method is very effective to understand the localized variations in mechanical behavior of the composites that are influenced by precipitation of reinforcements.

Wear Characterization of Al/B4C/CNT Composites for Different Alloying Composition
Abstract: Wear is a surface phenomenon that occurs predominantly at the surface of the material. It is majorly due to the rubbing action between two surfaces that is attributed to solid state contact. As wear is a material removal phenomena occurring at the outer surfaces, it is indeed very apt to develop materials that have wear resistant characteristics. Henceforth in the current work, it is therefore judicially justified to develop a …
