Low-Temperature Processed TiOx/Zn1−xCdxS Nanocomposite for Efficient MAPbIxCl1−x Perovskite and PCDTBT:PC70BM Polymer Solar Cells
(MDPI, 2019-06-03)The majority of high-performance perovskite and polymer solar cells consist of a TiO2 electron transport layer (ETL) processed at a high temperature (>450 °C). Here, we demonstrate that low-temperature (80 °C) ETL thin ... -
A Review of the Classification of Opal with Reference to Recent New Localities
(MDPI, 2019-05-15)Our examination of over 230 worldwide opal samples shows that X-ray diffraction (XRD) remains the best primary method for delineation and classification of opal-A, opal-CT and opal-C, though we found that mid-range infra-red ... -
Synthesis and evaluation of aminobenzothiazoles as blockers of N- and T-type calcium channels
(Elsevier, 2018-03-19)Both N- and T-type calcium ion channels have been implicated in pain transmission and the N-type channel is a well-validated target for the treatment of neuropathic pain. An SAR investigation of a series of substituted ... -
Calculated meteoroid production of hydroxyl in the atmosphere of Jupiter
(Elsevier, 2019-03-12)The atmosphere of Jupiter is mainly hydrogen and methane, with a large number of hydrocarbons calculated to be produced by photodissociation and subsequent reactions. It is assumed that oxygen is added by meteoroids. Recent ... -
Origins of N-formylmethamphetamine and N-acetylmethamphetamine in methamphetamine produced by the hydriodic acid and red phosphorus reduction of pseudoephedrine
(Elsevier, 2019-03-20)N-Formylmethamphetamine (FMA) and N-acetylmethamphetamine (AMA) are suspected to be trace by-products in methamphetamine (MA) produced from pseudoephedrine using the Nagai reaction. However, these amides are not rational ... -
On the Dynamics of Canyon–Flow Interactions
(MDPI, 2018-11-06)This paper explores the dynamical origin and physical characteristics of flow disturbances induced by ocean currents in interaction with shelf-incised submarine canyons. To this end, a process-oriented hydrodynamic model ... -
Characterizing the shape patterns of dimorphic yeast pseudohyphae
(The Royal Society Publishing, 2018-10-17)Pseudohyphal growth of the dimorphic yeast Saccharomyces cerevisiae is analysed using two-dimensional top-down binary images. The colony morphology is characterized using clustered shape primitives (CSPs), which are learned ... -
Polyelectrolyte-Coated Gold Nanoparticles: The Effect of Salt and Polyelectrolyte Concentration on Colloidal Stability
(MDPI, 2018-12-03)Gold nanoparticles are widely used in biomedical applications. Their ease of surface modification, biocompatibility and the presence of surface plasmons makes them ideal tools for a variety of investigations. Polyelectro ... -
Conducting Copper(I/II)-Metallopolymer for the Electrocatalytic Oxygen Reduction Reaction (ORR) with High Kinetic Current Density
(MDPI, 2018-09-07)The oxygen reduction reaction (ORR) is still the most research-intensive aspect of a fuel cell. The sluggish kinetics of the electrocatalysts toward the ORR requires large amounts of platinum to be used as cathode material, ... -
Effect of surface density silver nanoplate films toward surface-enhanced Raman scattering enhancement for bisphenol A detection
(IOP Publishing, 2018)This paper reports a study on surface-enhanced Raman scattering (SERS) phenomenon of triangular silver nanoplate (NP) films towards bisphenol A (BPA) detection. The NP films were prepared using self-assembly technique with ... -
Evaluation of the sub-surface morphology and composition of gunshot residue using focussed ion beam analysis
(Elsevier, 2019-02-11)Recent work in the forensic analysis of Gunshot residues (GSR) has suggested that the sub-surface or internal composition and morphology of these residues be explored. A particular area of interest is in heavy metal free, ... -
Detailed investigations into the Akabori–Momotani reaction for the synthesis of amphetamine type stimulants: Part 2
(Elsevier, 2018-02-06)The Akabori–Momotani reaction can be used to synthesise pseudoephedrine in 50% yield from N-methylalanine and benzaldehyde. This paper investigates electronic effects of substituted benzaldehydes on the reaction to synthesise ... -
Toxicogenetic study of omeprazole and the modulatory effects of retinol palmitate and ascorbic acid on Allium cepa
(Elsevier, 2018-04-05)Omeprazole (OME) is a proton pump inhibitor used for the treatment of various gastric and intestinal disease; however, studies on its effects on the genetic materials are still restricted. The present study aimed to evaluate ... -
Mechanism and kinetics of hydrothermal replacement of magnetite by hematite
(Elsevier, 2018-06-28)The replacement of magnetite by hematite was studied through a series of experiments under mild hydrothermal conditions (140–220 °C, vapour saturated pressures) to quantify the kinetics of the transformation and the relative ... -
Continuous flow synthesis of phosphate binding h-BN@magnetite hybrid material
(The Royal Society of Chemistry, 2018-12-05)Hexagonal boron nitride (h-BN) is rendered magnetically responsive in aqueous media by binding superparamagnetic magnetite nanoparticles 8.5–18.5 nm in diameter on the surface. The composite material was generated under ... -
Spatio-temporal geomorphological and ecological evolution of a transgressive dunefield system, Northern California, USA
(Elsevier, 2018-09-25)A series of historic aerial photographs in addition to the U.S. Coast Survey 1870 map were used to document evolution of the coastal barrier and transgressive dunefield system at the Lanphere-Ma-le'l Dunes on Humboldt Bay, ... -
Morphological evolution of the sandspit at Tortugueros Beach, Mexico
(Elsevier, 2018-10-14)Sand spits occur around the world with different shapes, dimensions and dynamics. While usually considered non-developable coastal features, development has taken place in several locations around the world, and because ... -
A forensic investigation on the persistence of organic gunshot residues
(Elsevier, 2018-09-01)Gunshot residues (GSR) are a potential form of forensic traces in firearm-related events. In most forensic laboratories, GSR analyses focus on the detection and characterisation of the inorganic components (IGSR), which ... -
