In this paper, we report a simple and fast method to produce uniform nano-sized Ag particles that can be dispersed in the oil phase by using oleic acid as solvent and capping agent. Oleylamine, a longchain amine that can act as an electron donor at elevated temperatures and is miscible with oleic acid, was selected as a reductant.

In the present work, we report on the dye removal efficiency of Cobalt chromite, CoCr2O4 nanoparticles synthesized via the solvothermal method. The obtained CoCr2O4 nanoparticles demonstrated that the dye removal efficiency of CoCr2O4 nanoparticles could be enhanced by a reduction of size or improved water dispersibility.

Nanoparticles have been extensively in recent years. The effective applications of nanoparticles depend on their sizes. Copper nanoparticles (CuNPs) are among metal nanoparticles which have been reported by many researchers. In this work, CNPs have been synthesized from copper sulfate via chemical reduction method in the presence of trisodium citrate dispersant and polyvinylpyrrolidone (PVP) as protecting agents.

Percentages of the grate (retained) and passed of the ground mineral are found for each sieve size by means of weight. The approximations of the retained and passed were calculated and found to intersect at 225 um. At the intersection, the percentage by weight passed through the sieve is 50 percent and the percentage by weight retained sieve is 50 percent, respectively.

With the advancement of diagnostic modalities, there is an increase in the number of individuals detected with thyroid nodules. There are multiple treatment options for the management of nontoxic benign nodular goiter. Radioactive iodine results in effective goiter size reduction which can be administered as out-patient basis and is an appropriate alternative for patients with higher risk for surgery.

This study investigated a modified chemical soil washing technique whereby Pb extraction in citrate solution and recovery of dissolved Pb by reductive precipitation (cementation) were simultaneously carried out in a single reactor by the addition of micro-sized zerovalent iron (mZVI) to decontaminate Pb-contaminated soil from a shooting range.

In this method, the internal DOFs are separated from the boundary DOFs, and decomposed onto a basis of static modes, and a basis of fixed interface modes [Craig et Bampton, 1968]. The use of a reduced basis for the fixed interface modes makes it possible to reduce the size of the system to be solved, and therefore to save the computational time compared to a classical finite element computation involving the complete system.

Perioperative temperature management is fundamental to ensure normothermia in patients. Fluid warmers, which have become smaller in size over the past few years, can help to maintain a stable body temperature. Potentially, the reduction of the size may influence the heating performance.

Our studies on the selective catalytic reduction of NO (SCR-deNO) properties of M/γ-Al2O3 (M = Mn, Co, Cu) nanocatalysts are presented. All catalysts were prepared by homogeneous deposition precipitation using urea as the precursor for the precipitating agent. The SCR activity followed the order Mn/γ-Al2O3 > Cu/γ-Al2O3 > Co/γ-Al2O3. The nanocatalysts were characterized with respect to their texture (N2-BET), particle size (TEM), reducibility (H2-TPR), and acidity (NH3-TPD).

Puerarin-coated gold nanoparticles (PUE-AuNPs) synthesized via green synthetic route, a new colorimetric sensor, efficiently detected the ciprofloxacin (CP) in tap water and cow milk samples. The PUE-AuNPs were characterized by UV-visible, FTIR, AFM, and DLS techniques and were found to be spherical with an average size of approximately 19–20 nm. FTIR spectrum confirms that functional groups such as –OH, -C=O, -CO and –C=C were responsible for the reduction of gold (III) chloride trihydrate. These functional groups acted as capping agents to form AuNPs.

The neutron tomography, although lower in spatial resolution compared with the X-ray synchrotron tomography and requiring higher acquisition time, is sensitive to the phase chemistry, and has the potential to study engineering size components. Bragg edge neutron transmission imaging allows for the mapping of two-dimensional elastic strains and was used to identify the fatigue crack from the reduction in the strain in the region where the crack propagated.

The reduction in flexural strength and compressive strength at 28 days is 14% and 25%, respectively at 7% SRA dosage. In addition, SRA significantly reduces the drying shrinkage and water absorption of mortar. At 7% SRA dosage, the drying shrinkage at 53 days is reduced by 60% while the water absorption rate at 24 hours is reduced by 54%. However, SRA has a minor effect on the pore size distribution, effective porosity, and cumulative intrusion volume of mortar.

A robust synthesis of iridium oxide (IrO2) nanoclusters using methanol as a reducing agent via the chemical reduction method is reported in this article. Polyvinylpyrrolidone (PVP) and polyoxyethylene(23) lauryl ether (POLE) were used as stabilizers. The formation of IrO2 nanoclusters was confirmed by the appearance of new absorption peak at 230 nm in UV-vis spectra. XRD and TEM were used to determine the degree of crystallinity and size of nanoclusters, respectively.
