We investigate the application of nanoscale topgates on exfoliated bilayer graphene to define quantum dot devices. At temperatures below 500 mK, the conductance underneath the grounded gates is suppressed, which we attribute to nearest neighbour hopping and strain-induced piezoelectric fields. The gate-layout can thus…
TiO 2 nanoparticles and nitrogen‐doped TiO 2− x N x nanoparticles dispersed in plasma polymer phase are produced by atmospheric pressure DBD in titanium tetraisopropoxide with dry air, mixture of N 2 and O 2 , and 100% N 2 used as carrier gases. Energy supply per monomer molecule (the Yasuda parameter) is found to be…
Stable, highly faceted and dispersed iron nitride particles supported on few layer graphene are obtained by ammonia decomposition on iron-based particles at the temperature commonly used for the synthesis of N-doped CNTs and graphene etching. The TEM/EELS analysis reveals nitrogen diffusion in a bulk of the particles.…
The intent of this paper is to identify the basic physical laws governing particle kinematics in a shotcrete spray. This paper presents a governing equation based on Newton’s second law where nozzle and airflow characteristics, and particle features are used to predict impact velocity of the material exiting the nozzl…
Polyethylene was flame retarded with two intumescent-type additives, 3,5-diaminobenzoic acid phosphate and ethylenediamine phosphate, which differ with respect to their decomposition onset temperatures, along with varying ratios of two grades of expandable graphite, also differing with respect to their onset temperatu…
A Raman study on hydrogen donors in ZnO reveals the properties of bond-centered hydrogen (${H}_{\mathrm{BC}}$) and hydrogen trapped in the oxygen vacancy (${H}_{\mathrm{O}}$). The donors are identified by their electronic $1s\ensuremath{\rightarrow}2s(2p)$ transitions and their characteristic local vibrational modes.…
The tensile, flexural, and impact behaviors of zea fiber-reinforced polyester composites were evaluated. The different proportion of fiber length, fiber content in weight percentage, and molding pressure was used as process parameters in the fabrication of zea–polyester composites. The parameters and their levels were…
The realization of arrays of high-aspect-ratio nitrogen-doped ZnO (NZO) nanorod is critical to the development of high-quality nanostructure-based optoelectronic and electronic devices. In this study, we used a solution-based method to grow arrays of vertically aligned high-aspect-ratio NZO nanorods on ZnO seed layer…
Covalent modification of proteins exerts significant effects on their chemical properties and has important functional and regulatory consequences. We now report the identification and verification of an electrically-active form of modified proteins recognized by a group of small molecules commonly used to interact wi…
Based on first-principles calculations, the coexistence of Ti vacancies (VTi) and O vacancies (VO) is first considered to study the origin of the ferromagnetic ordering in undoped rutile TiO2. The calculations show that VO can induce local magnetic moments in TiO2, however, the ferromagnetic (FM) exchange interaction…
A method for the formation of a low-temperature hybrid gate dielectric for high-performance, top-gate ZnO nanowire transistors is reported. The hybrid gate dielectric consists of a self-assembled monolayer (SAM) and an aluminum oxide layer. The thin aluminum oxide layer forms naturally and spontaneously when the alumi…
The coexistence of Li 2 MoO 4 ( LMO ) and Ni 0.5 Zn 0.5 Fe 2 O 4 ( NZO ) has been proven and their low‐temperature‐sintered magneto‐dielectric composites (1− x ) LMO – x NZO (volume fraction factor x = 0.1, 0.3, 0.5, 0.7) were prepared by the conventional solid‐state reaction method and were sintered below 700°C. It i…
Poly-L-lysine (PLL), which has been employed as a conductive polymer in the construction of some electrochemical sensors, can be prepared using L-lysine by cyclic voltammetry (CV) with a wide potential range. However, the presented explanation and description about its polymerization mechanism seems oversimplified bec…
Multidrug regimens can sometimes treat recalcitrant diseases when single-drug therapies fail. Recapitulating complex multidrug administration from controlled release films for localized delivery remains challenging because their release kinetics are frequently intertwined, and an initial burst release of each drug is…
In this work we present an atomistic simulation study analyzing the effect of ligand molecules on the morphology and crystalline structure of monolayer protected gold nanoparticles (NPs). In particular, we focused on Au NPs covered with alkyl thiolates (-SR), which form a strong covalent bond with the Au surface, and…
A series of tris(pentafluorophenyl)corrole (TPFC) tin(IV) and tin(II) complexes were prepared and studied by various characterization techniques including (1)H, (19)F, and (119)Sn NMR and UV-vis spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. The unusual 4-coordinate, monomeric, divalent tin(II)…
A series of Ni–La–Ox complex oxides with Ni/La integer molar ratios from 1 to 10 supported on pretreated cordierite ceramics were prepared by an impregnation method and tested for direct catalytic decomposition of N2O. The Ni–La–Ox complex oxides showed considerable synergy in N2O decomposition compared with pure nick…
Nanoparticles are attractive for many biomedical applications such as imaging, therapeutics and diagnostics. This new book looks at different soft nanoparticles and their current and potential uses in medicine and health including magnetoliposomes, micro/nanogels, polymeric micelles, DNA particles, dendrimers and bice…
Water‐repelling surfaces inspired by lotus leaves have been developed for their commercial needs in superhydrophobic and self‐cleaning coatings on glasses and windows. The extraordinary properties originate from their multiscale structures with waxy materials. To obtain high transparency as well as superhydrophobicity…
In recent years, silver nanoparticles (AgNPs) have been shown to possess broad antibacterial activity. The present study investigated the cytotoxicity of AgNPs to a common soil bacterium, Pseudomonas sp. The molecular mechanism involved in its stress response to AgNPs was also studied. The minimum inhibitory concentra…
