In this study, two different types of liquid cooling garments are designed and their cooling effects are comparatively investigated. The tubing lengths and the inner layers of these garments are taken as the same, and the other parameters of the garments differed. In the outer layer of the garments, 10 × 3 rib and sin…
Gelation in colloidal suspensions is mostly induced by attractive interparticle potentials. Beside these interactions, the mechanical properties of the gel are influenced by morphological aspects like fractality. In suspensions of liquid crystal (LC) and polymeric colloids, solvent-particle interactions dominate and c…
Liquid droplets on chemically patterned surfaces consisting of alternating hydrophilic and hydrophobic stripes exhibit an elongated shape. To assess the dynamics during droplet formation, we present experimental results on the spreading of glycerol droplets on such surfaces using a high-speed camera. Two spreading reg…
BACKGROUND: Mitochondria are a valuable resource for studying the evolutionary process and deducing phylogeny. A few mitochondria genomes have been sequenced, but a comprehensive picture of the domestication event for silkworm mitochondria remains to be established. In this study, we integrate the extant data, and per…
Cooperative electrostatic adsorption (CELA) is used to deposit monolayer coatings of silver nanoparticles on relatively chemically inert polymers, polypropylene, and Tygon. Medically relevant components (tubing, vials, syringes) coated by this method exhibit antibacterial properties over weeks to months with the coati…
The synthesis of spiropyrans was improved significantly with use of ultrasonic radiation. To show the broad applicability of this methodology a range of spiropyrans were prepared which are equipped with iodo, hydroxyl, ethinyl, or azido groups as potential building blocks for conjugation to functional pi-systems or bi…
Reticulated porous Ti 3 AlC 2 ceramic, a member of the MAX‐phase family (M n +1 AX n phases, where M is an early transition metal, A is an A‐group element, and X is carbon and/or nitrogen), was prepared from the highly dispersed aqueous suspension by a replica template method. Through a cathodic electrogeneration meth…
Using the first principles method, we study the growth behavior and electronic and magnetic properties of TiNi(n) (n = 1-12) clusters to clarify the effect of Ti modulation on the nickel nanostructures. Furthermore, chemisorption of H(2) was studied to understand the chemical reactivity of H(2) on the small Ni- and Ti…
Foods and pharmaceuticals materials are exposed to various environmental conditions during processing and while in storage; therefore, stability and quality are key attributes of concern. The properties of foods and pharmaceutical materials that define their quality are affected by conditions such as temperature, humi…
We report the use of a small concentration of ethanol in addition to ethylene as the carbon source for growth of dense vertically aligned “forests” of few-walled carbon nanotubes (CNTs). Through a detailed comparison of CNTs grown with and without ethanol added to the C 2 H 4 /H 2 feedstock, we quantify several import…
Octahedral monodisperse α-MnS and MnO nanoparticles have been synthesized by decomposing manganese oleate and elemental sulfur in octadecene at high (250−320 °C) temperature. The chemical composition of the obtained NPs depends on the Mn:S ratio in an unexpected way. Pure α-MnS NP samples are obtained when S:Mn ≥ 2:1,…
Dielectric spectroscopy measurements have been performed on a bent-core nematic liquid crystal and on its binary mixtures with a calamitic nematic. We have detected more dispersions in the bent-core compound than in the calamitic one, including one at an unusually low frequency of a few kilohertz. The dispersions dete…
The surface and interface enthalpies of cubic stabilized zirconia solid solutions containing 8, 10, and 12 mol % Y 2 O 3 were determined by a combination of calorimetric, morphological, and structural analyses techniques. Nanocrystalline samples with several surface areas and degrees of agglomeration were synthesized…
We formulate a concise deformation theory for periodic bar-and-joint frameworks in R d and illustrate our algebraic–geometric approach on frameworks related to various crystalline structures. Particular attention is given to periodic frameworks modelled on silica, zeolites and perovskites. For frameworks akin to tecto…
Zinc oxide (ZnO) is a potential candidate material for optoelectronic applications, especially for blue to ultraviolet light emitting devices, due to its fundamental advantages, such as direct wide band gap of 3.37 eV, large exciton binding energy of 60 meV, and high optical gain of 320 cm−1 at room temperature. Its l…
Collagen is the most abundant protein in the human body, providing mechanical stability, elasticity, and strength to connective tissues such as tendons, ligaments, and bone. Here, we report an extension of the MARTINI coarse-grained force field, originally developed for lipids, proteins, and carbohydrates, used to des…
A series of experimental precipitated calcium carbonates (PCCs) coated with commercial stearic acid (stearin), with the coating amount of stearin added to the PCC particles ranging from 3 to 13.5 wt %, were prepared in aqueous medium and characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetri…
Nanocluster impact on a free-standing graphene is performed by the molecular dynamics simulation, and the dynamical motion of the free-standing graphene is investigated. The graphene is bended by the incident nanocluster, and a transverse deflection wave isotropically propagated in the graphene is observed. We find th…
The carrier concentration of chemically synthesized Bi(2)Te(3)-based nanocrystals (NCs) is for the first time reported to be adjusted by forming ternary Bi(2-x)Sb(x)Te(3) NCs (x = 0.02, 0.05, 0.10, 0.20, 0.50, and 1.50) through partial substitution of Bi with Sb. Carrier concentrations of ternary Bi(2-x)Sb(x)Te(3) NCs…
We report results of micro-Raman spectroscopy investigation of the "graphene-like" mechanically exfoliated single-crystal bismuth telluride films with the thickness ranging from a few-nm-range to bulk limit. It is found that the optical phonon mode A1u, which is not-Raman active in bulk bismuth telluride crystals, app…
