A new soil extractant (H3A-1) with the ability to extract ammonium (NH4) nitrogen (N), nitrate (NO3) N, and phosphorus (P) from soil was originally developed and tested against 32 soils (CitationHaney et al. 2006). H3A-1 is composed of organic acid root exudates, which are naturally occurring, and lithium citrate. In…
A novel, highly flexible, conductive polymer-based fiber with high electric capacitance is reported. In its crossection the fiber features a periodic sequence of hundreds of conductive and isolating plastic layers positioned around metallic electrodes. The fiber is fabricated using fiber drawing method, where a multi-…
A two dimensional system of discs upon which a triangle of spins are mounted is shown to undergo a sequence of interesting phase transitions as the temperature is lowered. We are mainly concerned with the `solid' phase in which bond orientational order but not positional order is long ranged. As the temperature is low…
A direct observation of nucleation of Ge hut clusters formed by ultrahigh vacuum molecular beam epitaxy is reported for the first time. The nuclei of the pyramidal and wedge-like clusters have been observed on the wetting layer blocks and found to have different structures. The growth of the clusters of both species g…
Purpose – The purpose of this paper is to describe a very low‐cost way to prepare Ge nano/microstructures by means of filling the material inside porous silicon (PS) using a conventional and cost effective technique in which thermal evaporator with PS acts as patterned substrate. Also, the potential metal‐semiconducto…
A novel type of amino functionalized core-shell Ru(bpy)3-doped silica nanoparticles was synthesized using a simple and effective approach of reverse microemulsion. The nanoparticles were characterized by transmission electron microscope, fluorescence spectra, UV-Vis spectroscopy and tests of photostability and dye mol…
Purpose Zinc oxide (ZnO) is an emerging optoelectronic material due to its various functional behaviors. The purpose of this paper is to report on the fabrication and characterizations of ZnO microrods. Design/methodology/approach ZnO microrods were synthesized using sol‐gel immerse technique on oxidized silicon (Si)…
Abstract An asymmetric hybrid compound, in which one tetrathiafulvalene (TTF) unit is attached to a zinc phthalocyanine (ZnPc) ring, has been studied by spectroscopy and electrochemistry. Its Langmuir–Blodgett film-forming properties have also been examined.
Paclitaxel is routinely used in cancer chemotherapy to treat patients with ovarian, breast, lung, head and neck cancers. However, because of its low aqueous solubility, it's been administered as a Cremophor EL and ethanol solution, which is associated with increased toxicity and high therapeutic dose requirements. The…
Abstract Mechanical blends formed of 50 wt% of high-density polyethylene (HDPE) and 50 wt% of ethylene–propylene–diene-monomer (EPDM) elastomer have been loaded with 50 wt% of three different particle size of CaCO 3 , namely CaCO 3 300, CaCO 3 700, and CaCO 3 2000 whereby the latter has the smallest particle size of ∼…
Abstract The first semisolid phase synthesis of organic nanotubes was achieved by mixing an aqueous solution of metal salt with an alcoholic dispersion of glycylglycine lipid. The dry 80–240 g of nanotubes are easily obtained within a few hours using 1 L of solvent.
Abstract We systematically evaluated water contact and sliding angles on the lotus leaf from −10 to 80 °C under either extremely low or high relative humidity. SEM images revealed changes of the hierarchical structures after thermal treatment at different temperatures. The wettability recovery test showed consistent r…
We aimed to evaluate the role of a synthetic somatostatin analogue in delay procedure of experimental skin flaps. Thirty-six rats were randomly divided into 2 groups of 18 each to compare the possible local ischemic effect of octreotide with that of surgical delay in the dorsal random pattern skin flap model. The indu…
The inhibition effect of 2-carboxymethylthio-4-(p-methoxyphenyl)-6-oxo-1,6-dihy-dropyrimidine-5-carbonitrile (CPD) towards the corrosion of copper was studied in aerated stagnant 3.5% NaCl at 25 °C using ac techniques include electrochemical frequency modulation and electrochemical impedance spectroscopy as well as po…
Naturally occurring foam constituent and surfactant proteins with intriguing structures and functions are now being identified from a variety of biological sources. The ranaspumins from tropical frog foam nests comprise a range of proteins with a mixture of surfactant, carbohydrate binding and antimicrobial activities…
The high reset current IR in unipolar resistance switching now poses major obstacles to practical applications in memory devices. In particular, the first IR-value after the forming process is so high that the capacitors sometimes do not exhibit reliable unipolar resistance switching. We found that the compliance curr…
We report on early stages of submonolayer Ag island coarsening on Ag(111) surface at room temperature ($300$ K) carried out using realistic kinetic Monte Carlo (KMC) simulations. We find that during early stages, coarsening proceeds as a sequence of selected island sizes creating peaks and valleys in the island size d…
There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy and medicine. Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. In t…
The purpose of this study is to investigate the morphology of solidification microstructures 80% Cu-20%Sn on different solidification rate. The commercial pure copper and tin were melted in crucible furnace at temperature 1000oC. The molten metal was casted in permanent moulds which have variation temperature, i.e. 35…
A series of Fréchet-type dendrimers with 9-benzyloxymethylanthracene cores were synthesized and characterized. The chiral source for the dendrimers was an (S)-2-methyl-1-butoxy group in the 3-position of the benzene ring. Irradiation at 366 nm of a dilute benzene solution led to the formation of two diastereomers (1:1…
