The slip behavior of high-density polyethylenes (HDPEs) is studied over surfaces of different topology and surface energy. Laser ablation has been used to micro/nano-pattern the surface of dies in order to examine the effect of surface roughness on slip. In addition, fluoroalkyl silane-based coatings on smooth and pat…
The PLA (50% wt.)/PP (50% wt.), PLA (47.5% wt.)/PP (47.5% wt.)/paraffin (5% wt.), and PLA (47.25% wt.)/PP (47.25% wt.)/paraffin (5% wt.)/CuO·SiO 2 (0.5% wt.) composite nonwovens were obtained in one-step process by using the melt-blown technique. Thermal properties (by the DSC method), physicomechanical parameters, sp…
Metal oxide interlayers are promising for optoelectronic applications due to solution processability, optical transparency, and excellent charge blocking properties.
Abstract We conducted a taxonomical study of epiphytic diatoms on the macrophytes Polygonum hydropiperoides, Ludwigia peruviana and Alternanthera philoxeroides collected in the mesotrophic reservoir Piraquara II flooded in 2009, located in the state of Paraná. A total of 135 infrageneric taxa were identified, among th…
The catalytic property for O <sub>2</sub> dissociation of the pure Pt <sub>5</sub> cluster can be further improved by introducing the Pd atoms based on the morphology and composition.
-graphite flake consumed solid-state cathode. For further practical applications, miniature origami BFCs can directly generate energy from soft drinks.
The synthesis and post-polymerisation functionalisation of an epoxide-functional polycarbonate <italic>via</italic> the selective carbonate ring-opening polymerisation (ROP) of trimethylenepropane oxirane ether carbonate (TMOC) monomer was investigated using a range of organocatalysts.
The performance of fusion-bonded epoxy coatings can be improved through advanced composite coatings reinforced with nanomaterials. Hence, in this study a novel organic-inorganic nanocomposite finish was designed, synthesized, and characterized, achieved by adding <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML…
Synthetic amorphous silica nanoparticles (SAS NPs) have been used in various industries, such as plastics, glass, paints, electronics, synthetic rubber, in pharmaceutical drug tablets, and a as food additive in many processed foods. There are few studies in the literature on NPs using gene mutation approaches in mamma…
Multiple exciton generation (MEG) is a promising process to improve the power conversion efficiency of solar cells. PbSe quantum dots (QDs) have shown reasonably high MEG quantum yield (QY), although the photon energy threshold for this process is still under debate. One of the reasons for this inconsistency is the co…
Diagnosis by MRI is frequently non-trivial due to the low sensitivity of the technique. Signal enhancing contrast agents (CAs) are used to aid in the analysis of MR images. We present here a simple protocol for the preparation of responsive CAs based on Mn nanosheets. Mn nanostructures presented here undergo a chemica…
A humidity sensor made from a transferable PANI thin film exhibits relatively high sensitivity and short response/recovery times. The sensitive properties are tailorable by acid doping.
We performed comprehensive studies on the photoluminescence properties of the carbon dots prepared from citric acid (C-dotsCA) and citric acid + ethylenediamine (C-dotsCA+EDA). The cryogenic experiment confirmed that the excitation dependent fluorescence and the spectral relaxation dynamics of the C-dots are associate…
A dual-luminescent Ir( <sc>iii</sc> )–Eu( <sc>iii</sc> ) sensor is reported which changes luminescence colour from red to blue in the presence of a chemical warfare agent simulant.
Various unique physical, chemical, mechanical and electronic properties of carbon nanotubes (CNTs) make them very useful materials for diverse potential application in many fields. Experimentally synthesized CNTs are generally found in bundle geometry with a mixture of different chiralities and present a unique challe…
Modeling the corrosion inhibition of mild steel in HCl medium with inhibitor of pawpaw leaves extract is presented. The extract was analyzed using gas chromatography-mass spectrometry. Thermometric and gravimetric methods were employed in the corrosion inhibition study. The inhibition efficiency was modeled and optimi…

Li <sub>2</sub> TiO <sub>3</sub> dramatically improves the kinetics of LiAlH <sub>4</sub> decomposition and the onset temperature of LiAlH <sub>4</sub> is decreased to 75 °C.
Carbons from cane molasses with 8 m <sup>2</sup> g <sup>−1</sup> BET area yielded capacitances up to 153 F g <sup>−1</sup> at 0.5 mV s <sup>−1</sup> in 1 M H <sub>2</sub> SO <sub>4</sub> , with 35.2% pseudocapacitance contribution, due to the high surface concentration of quinone and carbonyl groups.
