The phase transition process from VO(2) (B) to VO(2) (A) was first observed through a mild hydrothermal approach, using hybrid density functional theory (DFT) calculations and crystallographic VO(2) topology analysis. All theoretical analyses reveal that VO(2) (A) is a thermodynamically stable phase and has a lower fo…
Expired ranitidine was tested as a corrosion inhibitor for mild steel in 1 M HCl using different techniques: weight loss, potentiodynamic polarization, open circuit potential and electrochemical impedance spectroscopy. The polarization resistance (R p ) value increased with increase in the concentration of the inhibit…
In this study, the reformate operation of anode supported solid oxide fuel cells (SOFC) is characterized by electrochemical impedance spectroscopy. The characterization is performed over a broad measuring range of temperature and H/C/O-ratios of the fuel. The kinetic parameters of the electrochemical oxidation of the…
The paper deals with the modification made to the general electrospinning setup. The emphasis is given to characterize the designs based on their applicability. Four basic categories are identified, namely, patterned fibers, fiber yarns, multicomponent, and deposition area of the fiber mat obtained. The mathematical m…
Silica nanoparticles with a balance of hydrophilic and hydrophobic surface properties exhibit surfactant-like behaviour, and as a consequence can strongly adsorb at oil/water interfaces to stabilize the formation of water micro-droplets. Here we exploit this strategy to construct a model of a primitive bio-inorganic p…
In this feature article, the atomic-scale understanding of the hydrogen spillover mechanism for hydrogen storage in metal-doped carbon materials and metal-organic frameworks is discussed by critically assessing recent computational and experimental studies. It is argued that the spillover mechanism involves: (a) the g…
Copper oxide (CuO) nanoparticles were synthesized by a sonochemical process using copper nitrate and sodium hydroxide in the presence of polyvinyl alcohol (PVA) as a starting precursor. The precipitated product was calcined at various temperature ranging from 400-700 °C.The physical microstructure and morphology of as…
Molecular self-assembly is a natural process occurring in many pathological conditions including Alzheimer's disease. Mechanistic insight into the self-assembly of amyloid fibrils led to the discovery of an aromatic dipeptide (diphenylalanine, FF) which is present in the core structural motif of Alzheimer's beta amylo…
Surfactant-free Pd nanoclusters (Pd NCs) (size: 1-1.5 nm) showed high catalytic activity in the Suzuki-Miyaura cross-coupling and Mizoroki-Heck reactions. The Pd NCs had a high turnover number, up to 6.0 × 10(8), which can be recycled at least five times without loss of catalytic activity.
Multiple-shape memory effects (SME) from dual to quintuple are realized in PMMA/PEG semi-interpenetrating polymer networks containing broadened glass transition and crystalline segments, which provide multi-gradient glass transition temperatures and an additional melting temperature as transition temperatures for mult…
Polyoxomolybdates, an important branch in polyoxometalates chemistry, present complicated solution chemistry and unmatched physicochemical properties, which endows us with both great opportunities and considerable challenges in creating new functional materials. This perspective highlights the recent development on th…
This is a report on photo-irradiated extracellular synthesis of silver nanoparticles using the aqueous extract of edible oyster mushroom (Pleurotus florida) as a reducing agent. The appearance, size, and shape of the silver nanoparticles are understood by UV-visible spectroscopy, field emission scanning electron micro…
Induced formation of metal nanoparticles in living plants is poorly understood. The sites for the reduction of Ag(+) and Au(3+) to Ag(0) and Au(0) metal nanoparticles in vivo in plants were investigated in order to better understand the mechanism of the reduction processes. Brassica juncea was grown hydroponically, fo…
A squaraine rotaxane endoperoxide with a truncated squaraine chromophore undergoes a cycloreversion reaction and emits green light that can be transferred to red acceptor dyes. The results demonstrate that chemiluminescence emission for squaraine rotaxane endoperoxides comes from the excited squaraine inside the rotax…
The creation of composite crystals formed by the epitaxial interaction between differing polymorphs of sulfathiazole (forms II and IV) has been reported through the experimental growth from ethanol. The intermolecular interaction between the crystal phases was calculated by application of the differential evolution gl…
We introduce x-ray microscopy as a method for imaging integrated circuits. Compared to physical de- layering combined with scanning electron microscopy, this method is non-destructive, requiring only sample thinning to approximately 100 um but otherwise leaving the sample intact. Using multiple views and 3D tomography…
The compound lead oxide sulfate PbSO4.PbO was prepared in our laboratory. The Thermal behavior of PbSO4 was studied using techniques of Thermogravimetry under air atmosphere from 25 to 1200°C. The identity of both compounds was confirmed by XRD technique. Results obtained using both techniques support same decompositi…
Abstract. The integration of performances in interactive textile fabric system has so far been rather complicated since they are based on multilayer or three-dimensional principles. These structures are today mainly put together by means of several processes, which is laborious and time consuming. In this interdiscipl…
Lubricant additives play significant role for reducing friction and wear of mechanical elements. The additives presented in 5W30 oil were developed for metal surfaces. However, they have been used in engine pieces covered with DLC coatings because they also offer the potential to reduce friction losses and wear in aut…
The superior piezoelectric properties of all polycrystalline ferroelectrics are based on the extent of non-180° domain wall motion under electrical and mechanical poling loads. To distinguish between 180° and non-180° domain wall motion in a soft-doped and a hard-doped lead zirconate titanate (PZT) ceramic, domain tex…
