Structural colors are optical phenomena of physical origin, where microscale and nanoscale structures determine the reflected spectrum of light. Artificial structural colors have been realized within recent years. However, multilayer structures require substantial fabrication. Instead we considered one-layer surface t…
A new Cu(II) complex with the antihypertensive drug telmisartan, [Cu8Tlm16]·24H2O (CuTlm), was synthesized and characterized by elemental analysis and electronic, FTIR, Raman and electron paramagnetic resonance spectroscopy. The crystal structure (at 120 K) was solved by X-ray diffraction methods. The octanuclear comp…
Coordination of bidentate 5-pentafluorophenyldipyrrinate (pfpdp) or 5-(2-thienyl)dipyrrinate (2-tdp) to a Ru(II) center bearing 2,2':6',2″-terpyridine-4,4',4″-tricarboxylate (tctpy) and a NCS(-) ligand results in strongly light-absorbing complexes [Ru(tctpy)(L)(NCS)] (L = pfpdp or 2-tdp). Anchored to a mesoporous TiO2…
Molecular dynamics (MD) simulations were carried out to study the hydrate structure and diffusion of water and cations in the clay interlayer region. The goal of this work was to examine the mechanisms by which the clay counterions influence the swelling and dispersion of shale. Three series of MD simulations were per…
The liquid-phase deposition (LPD) reaction and the deposition mechanisms for the preparation of hazy TiO 2, transparent TiO 2, and NH 4 TiOF 3 films were investigated by quantitative 19 F NMR analysis. Contrary to the conventional understanding, the 19 F NMR spectra indicated that BF 3 (OH) − formed within a short rea…
Abstract A series of CuZnAl catalysts modified with different promoters (Fe, Co, Ru, Zr, Mo, Mg, Mn, and Cr) have been prepared through co‐precipitation, characterised by applying a combination of techniques, and tested for carbon monoxide hydrogenation. Cu reducibility in CuZnAl catalysts was affected by the addition…
A rarely reported L1D (left-handed helical 1D chain) + R1D (right-handed helical 1D chain) → 3D polycatenated network, [Cd(H 2 ttac)bpp] n ( 1 ), constructed from the vertical interpenetration of triple-stranded homochiral helices, has been synthesized under hydrothermal condition by H 4 ttac (1,1′,2′,1″-terphenyl-4,4…
This study analyzes the synthesis of carbon-supported core–shell structured Cu@Pd catalysts (Cu@Pd/C) through a galvanic replacement reaction to be utilized in the electrocatalytic oxidation of formic acid. The strategy used in this study explores the relationship among lattice strain, electronic structure, and cataly…
A combined classical molecular dynamics (MD) and ab initio MD (AIMD) method was developed for the calculation of electrochemical windows (ECWs) of ionic liquids. In the method, the liquid phase of ionic liquid is explicitly sampled using classical MD. The electrochemical window, estimated by the energy difference betw…
A series of Ni–Co alloy nanocones arrays were fabricated by means of electrodeposition method without using any template. The alloy nanocones crystallized in the face-centered cubic lattice structure and grew preferentially along <110> directions. The aspect ratio of the alloy cones was found to increase with increasi…
Ti-6Al-4V alloy is the most commonly used alloy for dental and orthopedic implants. In order to improve osseointegration, different surface modification methods are usually employed, including self-assembled monolayers (SAMs). This study presents an investigation of both active (electroassisted) and passive (adsorptio…
Abstract The effectiveness of soy‐based edible films ( EF ) incorporated with essential oils ( EO ) from oregano ( OR , O reganum heracleoticum L .) or thyme ( TH , T hymus vulgaris L .) applied on oxidative stability of ground beef patties ( GBP ) was investigated at 4 C for 12 days. Higher antioxidant activity by OR…
Zeolitic imidazole frameworks-8 (ZIF-8) is a subclass of metal-organic frameworks (MOFs) with the transition metal cations (Zn2+) linked by imidazolate anions forming tetrahedral frameworks in zeolite-like topologies. This article reports on the synthesis of ZIF-8 nanoparticles by varying the synthesis parameters at r…
Hydrolysis of germanosilicate zeolites with the IWW structure shows two different outcomes depending on the composition of the starting materials. Ge-rich IWW (Si/Ge=3.1) is disassembled into a layered material (IPC-5P), which can be reassembled into an almost pure silica IWW on treatment with diethoxydimethylsilane.…
Carbon-based nanomaterials are being investigated for biomedical applications.Graphene oxide (GO), a monolayer of carbon, holds promise as a tissue engineering substrate due to its unique physicochemical properties.The aim of this study was to evaluate the effect of a GO coating on cell proliferation and differentiati…
In this study, durian seeds were chemically modified using KOH as an impregnating agent to prepare durian seed activated carbon (DSAC). DSAC was characterized using FTIR, BET, SEM, and proximate analysis techniques and used for the adsorption of Remazol brilliant blue reactive (RBBR) dye. The effects of pH, contact ti…
Based on analysis of a progressive collapse mechanism, this paper presents a simplified model for static analysis of progressive collapse response of RC beam-column substructures under midspan point loading. The proposed model expresses the load-deflection response directly, and it consists of three stages—beam mechan…
OBJECTIVES: This study evaluates high-resolution tomographic x-ray phase-contrast imaging in whole human knee joints for the depiction of soft tissue with emphasis on hyaline cartilage. The method is compared with conventional computed tomography (CT), synchrotron radiation absorption-based CT, and magnetic resonance…
We demonstrate a multiband background-free terahertz (THz) switch in photoactive chiral metamaterial using polarization conversion. Orthogonal arrangement of two asymmetrical split-ring apertures allows a high polarization conversion efficiency and low copolarization transmission. The chiral metamaterial embedded with…
Friction stir processing (FSP) is a solid state route with a capacity of preparing fine grained nanocomposites from metal sheets. In this work, we employed this process to finely distribute TiO2 nanoparticles throughout an Al–Mg alloy, aiming to enhance mechanical properties. Titanium dioxide particles (30 nm) were pr…
