Selected magnesium and zirconium-based alloys reinforced by nano precipitation hardening and nano dispersion strengthening mechanisms were examined in the power-law regime using long-term testing, strain-rate change measurements and constant structure steady-state creep tests to analyze the deformation and kinetic behavior of hcp Mg-Al-Ca-nm Al3Zr and hcp Zr-Sn-Nb-nm ZrO2 alloys at 423K and 673K, respectively.

A new first-order physical theory of long-term strength based on a dislocation model and analytical rateequations has been advanced for describing dynamic (time-dependent) microyield/creep resistance responsible for a potentially useful measure of the uniform strain preventing a premature fracturing of rapid-hardening crystals.

Micro structured zinc oxide (ZnO) is of potential use in solar cells, solid state gas sensors, and other optoelectronic devices. For the advancement of these technologies, a comprehensive understanding of these materials’ optical characteristics is considered essential. Using the spray pyrolysis (SP) method, thin films of ZnO micro rods are deposited from aqueous zinc chloride solution on silicon substrates held at 350±5 °C. The films have been studied using the data acquired from the X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS), reflectance and photoluminescence (PL) spectroscopy.

There are frequent grumbles of HIV investigations that appears to be getting whisker close to a minor but influential word cure. Toxicity, viral reservoirs, societal discrimination and drug resistance increases the challenges faced with HIV detection and treatment. Nanotechnological applications in drug development and delivery promises to combat and correct issues associated with HIV treatment through generation of drugs with pharmacological advantages that are pioneered by unique materials properties at nanoscale compared to bulk, atomic scale or molecular dimensions.

Materials based on CeO2-Sm2O3 system are promising candidates for a wide range of applications, but the phase relationship has not been studied systematically previously. To address this challenge, the subsection of the phase diagram for 600, 1100 and 1500 °C has been elucidated. Samples of different compositions have been prepared from nitrate acid solutions using conventional ceramic techniques; evaporation, drying, and calcinations. The phase relations in the binary CeO2-Sm2O3 system at 600- 1500 °C in air were studied from the heat treated samples using X-ray diffraction analysis and in the overall concentration range. It was established that in the binary CeO2-Sm2O3 system there exist fields of solid solutions based on monoclinic (B) modification of Sm2O3, cubic (C) modification of Sm2O3 and cubic modification of CeO2 with fluorite-type structure (F). The systematic study that covered whole composition range excluded formation of new phases. The refined lattice parameters of the unit cells and the boundaries of the homogeneity fields for solid solutions were determined.

A novel heat treatment process has been conceived for creation of Austempered Ductile Iron (ADI) with combination of high strength and high ductility. The process involves a step up austenitization of ductile cast iron after initial austenitization in the lower intercritical temperature range, then raising the temperature to the fully austenitic region followed by austempering at low bainitic temperatures.

Metal oxide nanoparticles are becoming essential in various biomedical applications, from diagnostics and imaging to anticancer therapy, bacterial infections, wound healing, and others. The application these nanostructures for immunotherapy is also emerging, particularly because they undergo phagocytosis and transmission by macrophages, and exhibit pro- or anti-inflammatory features depending on the nanoparticle’ content and pathological context.

Anisoprint, manufacturer of continuous carbon fiber 3D printers and materials, launches new material - Composite Basalt Fiber (CBF). Parts reinforced with this material by anisoprinting technology have better properties than their counterparts from metal or plastic: 15 times stronger than plastic, 5 times lighter than steel, 1.5 times stronger and lighter than aluminium. Anisoprintint technology is based on Composite Fiber Co-extrusion process .

Polyurea is a reaction product of an isocyanate with an amine and protective coatings based on polyurea are finding extensive application in diverse fields, especially towards protection of underlying structures for any particular isocyanate, the properties of the final product can be tailored by tweaking the constituents of the amine resin blend, especially chain extenders, chain length and crosslinker. In this review, we explicate the effect of various factors viz. soft segment length, type and concentration of chain extender and crosslinker on the material properties of polyurea.
