We present a theoretical and experimental study of resonant inelastic x-ray scattering on a large group of chlorinated hydrocarbons: CH3Cl, CH2Cl2, CHCl3, CCl4, CH3CH2Cl, ClCH2CH2Cl, CH3CHCl2, CH3CCl3, C2H2Cl2-iso, C2H2Cl2-cis, C2H2Cl2-trans, and C6H5Cl. Differences in structural and dynamical properties of the molecu…
We report on the first ever combination of a thin film of lead zirconate titanate (PZT) with a liquid crystal (LC) layer. Many liquid crystal applications use a transparent conductive oxide to switch the liquid crystal. Our proposed processing does not, instead relying on the extremely high dielectric constant of the…
The combustion synthesis and conventional solidstate reaction method was used to synthesize Gadolinium oxide (Gd2O3) phosphor. Nanoranged Gd2O3was successfully synthesized by ignition of gadolinium nitrate followed by combustion in the presence of urea, and for the solid-state reaction method, boric acid was used as a…
Castellaroite (IMA2015-071), Mn 2+ 3 (AsO 4 ) 2 •4.5H 2 O, is a new secondary arsenate mineral from the Monte Nero mine, Rocchetta Vara, La Spezia, Liguria, Italy and the Valletta mine, near Canosio, Cuneo, Piedmont, Italy.It crystallized from As-and Mn-rich hydrothermal fluids in an oxidizing environment.At Monte Ner…
Clotrimazole (CZ)-loaded N-naphthyl-N,O-succinyl chitosan (NSCS) micelles have been developed as an alternative for oral candidiasis treatment. NSCS was synthesized by reductive N-amination and N,O-succinylation. CZ was incorporated into the micelles using various methods, including the dropping method, the dialysis m…
A suite of 60 mineral samples with compositions intermediate between pseudomalachite, Cu 5 (PO 4 ) 2 (OH) 4 , and its arsenate analogue cornwallite, and between kipushite, (Cu,Zn) 6 (PO 4 ) 2 (OH) 6 ·H 2 O, and its arsenate analogue philipsburgite was investigated by electron-probe microanalysis, scanning electron mic…
The response of human bone marrow-derived mesenchymal stem cells (hMSCs) encapsulated in three-dimensional (3D) charged protein hydrogels was studied. Combining silk fibroin (S) with recombinant human tropoelastin (E) or silk ionomers (I) provided protein composite alloys with tunable physicochemical and biological fe…
Porous organosilicate thin films (SiOCH) deposited by plasma-enhanced chemical vapor deposition (PECVD) are used as dielectric layers in advanced microelectronic interconnections and as chemical layers in chemical sensors and biosensors. One challenge is to increase the porosity in these films, the classical method be…
The behavior of the chemical potential of the species CaCO 3 and MgCO 3 in proximity of the (10.4) crystal face of calcite and magnesite is determined at the quantum–mechanical level by adopting a recent calculation strategy conceived in our research laboratory. A very peculiar trend of this quantity from the (10.4) s…
A novel, efficient, and direct blend of solvents, tetrabutylammonium acetate/dimethyl sulfoxide (TBAA/DMSO), was used for the dissolution and regeneration of bamboo pulp. Regenerated fibers were successfully prepared by a wet spinning process. The bamboo pulp without any pretreatment was readily soluble in the solvent…
Single crystals of the 1:1 layered iron silicate cronstedtite from the new occurrence in Pohled, Czech republic were studied with aid of the single crystal X-ray diffractometer with area detector. Chemical composition of some crystals were determined by the EPMA. Three types of crystals were discerned: 1) mixed crysta…
Blister tests are commonly used to determine the mechanical and interfacial properties of thin film materials with recent applications for graphene. This paper presents a numerical study on snap transitions of pressurized graphene blisters. A continuum model is adopted combining a nonlinear plate theory for monolayer…
This paper presents the mechanical and tribological characteristics of the NiTi shape memory alloy (SMA) fabricated by powder metallurgy. This material has prominent applications in micro-electromechanical systems, medical implants, actuator, space and aerospace industries, etc. In every field, wear characteristics pl…
Two-photon polymerization (TPP) is of increasing interest due to its unique combination of truly three-dimensional (3D) fabrication capability and ultrahigh spatial resolution of ~40 nm. However, the stringent requirements of non-linear resins seriously limit the material functionality of 3D printing via TPP. Precise…
Graphene oxide (GO) was prepared via Hummers' method and reduced by hydrazine monohydrate. GO was modified with (3‐methacryloxypropyl)triethoxysilane (MPS) and the obtained GO‐MPS nanosheets were reduced by hydrazine monohydrate. The different modified nanosheets were utilized to fabricate microballoons based on methy…
The influence of the electron-phonon (e-ph) interactions on the filed-included polaron dynamics in armchair graphene nanoribbons (GNRs) is theoretically investigated in the scope of a two-dimensional tight-binding model. The results show that the localization of the polaronic charge increases when the strength of e-ph…
While comprehensive researches have been conducted on modeling the electromechanical stability of wide-enough beam-plate nano-switches, few researchers have focused on modeling the electromechanical instability of narrow-width nano-switches. For such systems, considering the coupled effects of surface stresses and siz…
Cf/ZrC, Cf/SiC and Cf/ZrC–SiC composites were successfully prepared by polymer infiltration and pyrolysis (PIP) using polycarbosilane and a liquid ZrC precursor. The densification process, mechanical properties and microstructures were studied in a view of comparison. After the same total 20 PIP cycles, the Cf/ZrC, Cf…
