Aqueous high molecular weight linear polyethylene nanocrystal/graphene composite dispersions were produced in situ by ethylene insertion polymerization in water or alternatively via a postpolymerization technique. Graphene was used without any prior compatibilizing surface modification. Remarkably, the Ni(II) salicyla…
The aim of this work was to assess a number of coatings developed for Mg for biomedical applications. The Mg substrates were high‐purity (HP) Mg and ME10, an alloy recently developed for improved extrudability. The research utilized the new fishing‐line specimen configuration to allow direct comparison to our recent i…
Formulations of poly(lactic acid) (PLA) reinforced by curaua leaf fibers were prepared and characterized. This biocomposite has material characteristics such as biodegradability and renewability. This work aimed to develop a PLA/curaua leaf fiber composite as a sustainable biodegradable polymer composite. The PLA and…
The spontaneous degradation of asparaginyl and aspartyl residues to isoaspartyl residues is a common type of protein damage in aging organisms. Although the protein-l-isoaspartyl (d-aspartyl) O-methyltransferase (EC 2.1.1.77) can initiate the repair of l-isoaspartyl residues to l-aspartyl residues in most organisms, n…
Hydrotalcite is a layered double hydroxide (LDH) consisting of brucite-like sheets of metal ions (Mg-Al). In this work, hydrotalcites were synthesized, and boron removal from oilfield wastewater was evaluated. LDHs were synthesized using the co-precipitation method. The calcined products (CLDHs) were obtained by heati…
Amorphous GexSixTe1−2x glasses are studied as a function of composition by a combination of experimental and theoretical methods, allowing for a full description of the network structure in relationship with physico-chemical properties. Calorimetric and thermal measurements reveal that such glasses display an anomalou…
BACKGROUND: The genus Fusarium comprises a heterogeneous group of fungi important for agriculture. Fusarium solani f. sp. eumartii (F. eumartii), historically considered to be a fungal pathogen of potato, has also been associated with tomato disease. Currently, chitosan and its derivatives have been receiving more att…
Fast crystal growth can abruptly emerge as molecular liquids are cooled to become glasses, a phenomenon presently unknown for other materials. This glass-to-crystal (GC) mode can cause crystallization rates orders of magnitude faster than those predicted by standard models. While GC growth is known for 12 systems, its…
This study reports on the use of soluble biobased organic substances (SBO) with emulsifying properties in the production of oil-in-water emulsions for industrial consumption. One of the potentially interesting applications is in formulation of metalworking fluids, which typically consist of oil-in-water emulsions used…
To improve blood compatibility of poly(ether ether ketone) (PEEK), surface modification with methacryloyl-functionalized phospholipid polymers was performed through self-initiation graft polymerization. The copolymers (PMA) of 2-methacryloyloxyethyl phosphorylcholine (MPC) and 2-aminoethyl methacrylate hydrochloride w…
We introduce a strategy for the fabrication of silver/polycarbonate (Ag/PC) nanocomposite flexible films of (20 ± 0.01) μm thickness with different filling factor of surface plasmon metal using customized solution cast-thermal evaporation method. Structural characterizations confirmed the good crystallinity with cubic…
Hybrid natural fiber composites made from the combination of natural fiber and synthetic fiber offers the performance solution while in the same time able to provide further balance between cost and sustainability requirements for automotive structural application. Despite such advantages, the task of designing such h…
Abstract We hybridize core–shell‐structured metal‐nitride nanowires with a 3D carbon substrate. Such electrodes demonstrate a high volumetric capacitance and good cycling stability, owing to the synergistic integration of titanium nitride and vanadium nitride, as well as the vast surface area and conductive network pr…
Graphene on Ir(111) is studied using scanning tunneling microscopy (STM) and x-ray standing waves (XSW). The graphene layer has a corrugated shape due to the moir\'e pattern formed as a result of a spatially varying interaction strength between graphene and its substrate. The coherent fraction ${F}^{(111)}$ determined…
The light transmission spectrum has been calculated for a "cholesteric liquid crystal-phase plate-metal" structure. It is shown that the system can have an isolated waveguide surface mode with characteristics efficiently controllable by external fields acting on the cholesteric. The degree of localization of surface m…
Nitrogen-expanded austenite, γ N , with high and low nitrogen contents was produced from AISI 316 grade stainless steel powder by gaseous nitriding in ammonia/hydrogen gas mixtures. In situ synchrotron X-ray diffraction was applied to investigate the thermal expansion and thermal stability of expanded austenite in the…
INTRODUCTION: Malignant gliomas remain one of medicine's most daunting unsolved clinical problems. The development of new technologies is urgently needed to improve the poor prognosis of patients suffering from these brain tumors. Magnetic nanomaterials are appealing due to unique properties that allow for noninvasive…
CO 2 adsorption at elevated pressure was studied in a Mg–Al (Mg/Al = 3) layered double hydroxide (LDH). The double-layered structure was prepared via a coprecipitation method. The sample’s structure and microstructure evolutions were characterized using X-ray diffraction, scanning electron microscopy, N 2 adsorption,…
The continuous-time random walk (CTRW) describes the single-particle dynamics as a series of jumps separated by random waiting times. This description is applied to analyze trajectories from molecular dynamics (MD) simulations of a supercooled polymer melt. Based on the algorithm presented by Helfferich et al. [Phys.…
We investigate the adsorption of submicrometer bulk-synthesized polymer dumbbells to oil-water interfaces using freeze-fracture, shadow-casting (FreSCa) cryo-scanning electron microscopy. We find that the dumbbells are amphiphilic and adsorb to the interface with a preferred orientation. Most particles adsorb in a til…
