Myostracum, which is connected from the umbo to the edge of a scar, is not a single layer composed of prismatic layers, but a hierarchically complex multilayered shape composed of minerals and an organic matrix. Through the analysis of the secondary structure, the results revealed that a β-antiparallel structure was p…
The effect of strontium content on Cr deposition and poisoning in barium strontium cobalt ferrite electrodes, Ba 1− x Sr x Co 0.8 Fe 0.2 O 3−δ (BSCF, 0.3 ≤ x ≤ 0.7), was investigated at 900°C for 20 h with a cathodic polarization of 200 mA cm −2 . In contrast to the superb and stable electrochemical performance of the…
We present several methods for tuning the localized surface plasmon resonance (LSPR) wavelength of conductive nanoparticles (NPs) over the ultraviolet to near-IR (UV-NIR) region. The methods presented in this article include changing the size of the icosahedral Pd NPs (LSPR in the UV region), using in-phase and antiph…
Microparticles with homogeneous properties are crucial for pharmaceutical applications where the prior knowledge of exact drug loading and release behaviour is essential to achieve targeted therapeutic goals. Various methods such as membrane microemulsion or templating to assemble uniform particles often involve multi…
We have prepared thin films of PbSe quantum dots (QDs) featuring three different ligands, oleic acid (OA), butylamine (BA), and 1,2-ethanedithiol (EDT), which have pronounced affects on the arrangement and photovoltaic performance of the PbSe QDs in the thin films. Transmission electron microscopy revealed that ligand…
In this work, we demonstrate a simple gas-phase process to synthesize ZnO with exposed reactive {0001} facets without the use of any capping agent.
In the present study, for the first time, without the help of any amphiphilic polymers or polymerizable surfactants, 3-mercaptopropionic acid (MPA) capped CdTe quantum dots (QDs) could be one-pot copolymerized into poly(N-isopropylacrylamide) (PNIPAM) microspheres during the monomer polymerization process just by cont…
Aluminium complexes bearing sterically bulky benzotriazole-phenoxide ligands are synthesized and characterized structurally. The reaction of 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol ((CMe2Ph)BTP-H) or 2-(2H-benzotriazol-2-yl)-4,6-di-tert-butylphenol ((t-Bu)BTP-H) with AlMe(3) (1.2 molar equiv.) i…
Mesoporous nanocomposite materials have been fabricated through integration of evaporation-induced self-assembly and deep X-ray lithography. Micropatterned films made using a mesoporous ordered silica matrix which contains silver nanoparticles have been obtained. The exposure of the mesoporous films to high energy X-r…
Both Keggin-type phosphotungstic acid (HPW) and Pd are not prominent catalysts towards the oxygen reduction (ORR), but their composite Pd-HPW catalyst produces a significantly higher electrochemical activity for the ORR in acidic media. The novel composite catalyst was synthesized by self-assembly of HPW on multi-wall…
We report rapid, sensitive, and direct detection of 2,4-dinitrotoluene (DNT) vapor using tailored gold nanoparticles (Au-NPs) as the SERS substrate. The Au-NPs were synthesized using the UV-assisted photo-chemical reduction method and subsequently formed a monolayer on the glass slide through polymer-mediated self-ass…
The choice of proper joining technology is an essential aspect of designing and manufacturing activity. New product designs enforce joining different materials in a new joining method. Clinching is a relatively new joining technology in which sheet metal parts are deformed locally without use of any additional element…
New biocompatible temperature-responsive hydrogels have been obtained by using unprecedented low concentration of amyloid fibril-PNiPAM hybrids. The viscoelasticity of the hydrogels can be finely controlled by tuning the PNiPAM layers without changing the structure or concentration of the amyloid fibrils.
A simple and rapid method to determine gadolinium (Gd) concentrations in urine and blood plasma samples by means of total reflection X-ray fluorescence (TXRF) was developed. With a limit of detection (LOD) of 100 μg L(-1) in urine and 80 μg L(-1) in blood plasma and a limit of quantification (LOQ) of 330 μg L(-1) in u…
A series of linear fluorosilicone pentablock copolymers consisting of poly(dimethylsiloxane) (PDMS), poly(methyl methacrylate) (PMMA) and poly(dodecafluoroheptyl methacrylate) (PDFHM), named as PDMS-b-(PMMA-b-PDFHM)2, have been synthesized by ATRP and their thermal properties, self-assembly behavior in different solut…
Ripples naturally occur in graphene sheets. First-principles calculations reveal that, by altering the pyramidalization angles of the carbon atoms, these ripples can be used to direct the chemical reactivity of graphene towards hydrogenation. A fraction of the carbon atoms of a rippled graphene, located around the cre…
Y 2−x−y O 3 :xBi 3+ ,yEu 3+ phosphors were prepared by co-precipitation method and characterized by X-ray diffraction and photoluminescence spectra. Under the excitation of 320–350 nm ultraviolet light, these phosphors show three emission bands; the one observed at 612 nm is attributed to Eu 3+ and the other two bands…
Fe-ZSM-5 zeolites with uniform crystal size and shape were synthesized by a hydrothermal method, and these parent zeolites were desilicated by an alkaline-treatment method to obtain mesoporous Fe-ZSM-5 (meso-Fe-ZSM-5) zeolites. Both Fe-ZSM-5 and meso-Fe-ZSM-5 zeolites were characterized by XRD, N2 adsorption–desorptio…
In the present work, we report on the self-organized growth of TiO(2) layers consisting of a highly aligned nanochannel morphology. We show that an electrochemical anodization process of Ti in a hot glycerol/K(2)HPO(4) electrolyte can be adjusted to yield these self-organized TiO(2) structures. The channel diameter an…
Carbon microspheres(CMSs) in a diameter of 10colonm were prepared by the hydrothermal carbonization of starch under different solution pH value. The structures and surface chemical properties of obtained CMSs before and after carbonization were characterized and compared by SEM images, nitrogen adsorption isotherms an…
