Controlled synthesis of single crystal gold nanorods (Au NRs) with desired dimensions, narrow polydispersity, and minimal byproducts depends critically on the state of the seed solution. Herein, we clarify the growth of cetyltrimethylammonium bromide stabilized Au seeds and their impact on conventional seed-mediated g…
The PDMS sealed aligned Ag nanowire/PANI composite film as a multi-dimensional pressure sensor.
In this study, we have shown that substitution of chloride ligand for imidazole (Im) ring in the cyclometalated platinum complex Pt(phpy)(PPh 3 )Cl ( 1; phpy, 2-phenylpyridine; PPh 3, triphenylphosphine), which is nonemissive in solution, switches on phosphorescence of the resulting compound. Crystallographic and nucl…
Pt II complexes have attracted much attention due to their readily derivatizable molecular structures and efficient production of triplet excited states and have been extensively used in many areas. Conventional Pt II complexes usually exhibit small molar absorption coefficients in the visible spectral region, and the…
Understanding the key factor controlling phase transitions of correlated oxides by chemical doping is becoming of fundamental and technological interest. Here, we report vanadium chain symmetry as an effective means of mediating the structural phase transition (SPT) temperature in hydrothermal Cr-doped VO 2 . In-situ…
A novel technique called interdendritic-melt solidified control (IMSC) was developed to manufacture equiaxed superalloy in the efforts of reducing porosity. The effect of process parameter, such as withdrawal rate, of the IMSC on the porosities and mechanical properties of IN792 alloy was investigated, compared with c…
The adsorption and inhibition effects of three benzimidazole derivatives (BDD), namely: 2-(2-pyridyl)benzimidazole (PBD), 2-bromo-1H-benzimidazole (BrBD), and 2-chlorobenzimidazole (ClBD) on mild steel corrosion in 1 M HCl have been studied by electrochemical and weight loss methods.Results showed that inhibition effi…
Telechelic PEG‐polymers end‐capped by diphenylalanine (FF) motives and containing a DOTA‐Gd complex, bound on a lysine side chain at the centre of peptide moiety, are studied for their assembling properties and for the relaxometric behavior. The observed variations in terms of relaxivity are correlated to the assembli…
Summary Shape‐memory polymers (SMPs) belong to a class of smart materials that have shown promise for a wide range of applications. They are characterized by their ability to maintain a temporary deformed shape and return to an original parent permanent shape. In this paper, we consider the coupled photomechanical beh…
We performed high-resolution polarized optical transmission spectroscopy and theoretical studies of multiferroic $\mathrm{EuF}{\mathrm{e}}_{3}{(\mathrm{B}{\mathrm{O}}_{3})}_{4}$ single crystals in the three phases: paramagnetic $R32\phantom{\rule{0.28em}{0ex}}(T>{T}_{\mathrm{s}}=84\phantom{\rule{0.28em}{0ex}}\mathr…
Folate-conjugated nanomaterials have been widely investigated for drug and imaging-agent delivery. In this work, two folic acid (FA) conjugated iron oxide particles (IOP), a ∼40 nm diameter FA-IOP and a ∼450 nm diameter FA-IOP(FA-SeraMag), were synthesized. Both particles aggregated in the presence of serum folate-bin…
Eight new members of a family of mixed-metal (Mo,W) polyoxometalates (POMs) with amino acid ligands have been synthesized and investigated in the solid state and solution using multiple physical techniques. While the peripheral POM structural framework is conserved, the different analogues vary in nuclearity of the ce…
The surface properties of CeO 2, Pr-CeO 2, and 5% and 15% Cu-doped Pr-CeO 2 were investigated using methanol as a probe molecule through adsorption and desorption studies carried out using in situ DRIFTS. It was revealed that the surfaces of the 5% and 15% Cu materials were dominated by reduced cations/vacancies and t…
Zinc sulfide thin films were deposited by plasma enhanced atomic layer deposition (PE-ALD) using diethylzinc and H2S/Ar plasma. The growth characteristics were studied in situ with spectroscopic ellipsometry and ex situ with x-ray reflectometry. The growth was linear and self-limited. Furthermore, it was demonstrated…
To shed light on intramolecular charge-transfer phenomena in 1,2,3-triazole-linked materials, a series of 1,2,3-triazole-linked push-pull chromophores were prepared and studied experimentally and computationally. Investigated modifications include variation of donor and/or acceptor strength and linker moiety as well a…
In this study, antimicrobial packaging films were prepared by coating silver (Ag) nanoparticles onto the surface of low density polyethylene ( LDPE ) films modified by corona air plasma. The possibility of these films for use in the packaging of milk was studied. The influence of input power of the corona discharge tr…
The effect of hydrogenation on the structure of Ru 19 – has been studied using a combination of trapped ion electron diffraction and density functional computations. While the bare Ru 19 – cluster has a closed-shell octahedral geometry, hydrogenation of the cluster changes the structure type of the ruthenium core towa…
By combining electrochemical experiments with mass spectrometric analysis, it is found that using short chain oligomers to improve the cycling stability of conducting polymers in supercapacitors is still problematic. Cycling tests via cyclic voltammetry over a potential window of 0 to 1.0 V or 0 to 1.2 V in a two-elec…
Dielectric spectroscopy measurements are carried out in the temperature range from about 100 to 145 K on nominally pure ice V as well as on crystals doped with KOH and with HCl in order to investigate their reorientation dynamics at ambient pressure. The orientational glass transition temperature of pure ice V is dete…
The present study introduces the first polycarbonate system that can reversibly be transformed into small molecules.
