In this study, we investigated the functionality- and size-dependent differentiation capability of bulk nanoporous polystyrene (PS) materials in aqueous environments. A three-arm star block copolymer (consisting of dibranched PS and linear polylactide (PLA) blocks) was employed to prepare PS nanochannels with the aver…
The article discusses the results of efficiency improvement of wide-range nickel-zinc ferrites by increasing the role of the dielectric subsystem in the formation of radio-wave absorbing properties of material due to the action of technological factors. The influence of doping additives and gas conditions of furnace a…
For a very long time, debris particles have been blamed to causing serious problems in machine-element contacts such as those of bearings and gears. This involves a huge number of mechanisms and machines worldwide. The financial cost associated with machinery failure under such circumstances is enormous. Past research…

We confine a monodisperse bubble monolayer between the two parallel plates of a rheometer. One plate is fixed and the other undergoes an oscillatory tangential motion, so that the bubbles are sheared. We measure the shear stress as a function of the imposed strain amplitude and frequency. The interfacial shear and dil…
Inspired by the mining tradition of the Copper Country area in Michigan (USA) and the original objectives of Michigan Tech’s founders, a research program with the mission to explore and promote new materials and products containing copper has been developed. Both ionic and elemental copper have been proven to effectiv…
This chapter focuses on the applications for nanobiotechnology. Electrospinning is advantageous in this field specifically for tissue engineering, drug delivery, and enzyme engineering purposes. Hexafluoropropanol is the most used solvent for electrospinning of natural polymers. polyethylene oxideis frequently used to…
Invisibility cloaks designed by transformation optics include a perfect shield, which exclude electromagnetic fields from the cloaked region. Due to the shield, observers inside the cloak cannot see the outside. We propose a cloak that permits communication with the outside, based on a layered photonic crystal (PC) st…
Abstract We propose an active multilayer mirror structure for extreme ultraviolet (EUV) wavelengths, which can be adjusted to compensate for reflectance changes. The multilayer structure tunes the reflectance via an integrated piezoelectric layer that can change its dimension due to an externally applied voltage. Here…
Adsorption of decapeptide neuromedin B (NMB) on copper electrode has been investigated by in situ surface-enhanced Raman scattering (SERS) spectroelectrochemistry in the temperature interval from 12 to 72 °C at -0.600 and -1.000 V potentials. It was found that intensities of peptide bands decrease at temperatures abov…
Abstract Functional brushes have recently emerged as an extremely versatile way to modify surface properties in a robust and controlled way. In this study, well‐defined, high density oligo‐ N ‐isopropylacrylamide (oligoNIPAM) brushes with OH and COOH end‐groups were fabricated through a reliable strategy by the comb…
The lack of a centre of inversion in a cholesteric liquid crystal allows linear cross couplings between thermodynamic forces and fluxes that are polar vectors and pseudovectors, respectively. This makes it possible for a temperature gradient parallel to the cholesteric axis to induce a torque that rotates the director…
Abstract Piezoelectric films were prepared by incorporation of lithium niobate (LiNbO 3 ) nanoparticles into copolymer of vinylidene difluoride and trifluoroethylene. Nanoparticles of LiNbO 3 with ferroelectric phase were successfully synthesized and dispersed homogenously by ultrasonication in the copolymer matrix wi…
A novel series of linear supramolecular hydrogen bonded liquid crystals (SMHBLC) have been investigated. Complimentary hydrogen bonds are formed between p-n nonyloxy benzoic acid and various p-n alkyloxy benzoic acids whose carbon chain length varied from 5 to 12. The formed mesogens are characterized by Fourier Trans…
Responsive or smart contrast agents (SCAs) provide new opportunities in magnetic resonance imaging (MRI) to examine a number of physiological and pathological events. However, their application in vivo remains challenging. Therefore, much research is focused on the optimization of their properties, to enable their use…
This study describes the synthesis and characterization of a new supported bentonite catalyst prepared by the two-step modification of Na-bentonite. In the first step, Na-bentonite is modified with cetyl pyridinium bromide (CPB) to give a monolayer bentonite (CP-bentonite) in which surfactant ions are adsorbed by cati…
This chapter discusses the studies on the elucidation of potential and impact of nanotoxicity associated with nanomaterials in nanobiotechnology. The reason for this may be that the translocation ability of nanoparticles is partially dependent on the particle size and solubility. The nature and intensity of biological…

Eleven members of a novel azoester homologous series entitled 2-[4′-n-alkoxy benzoyloxy]-naphthylazo-2″-methoxybenzenes are reported. The methyl to n-butyl homologues are nonmesomorphic, but the other homologues are mesomorphic. The pentyl, hexyl, and hexadecyl homologues exhibit only the nematic phase. The octyl, dec…
