High regio- and site selectivity of [2 + 3] dipolar cycloaddition reaction of 4-trifluoromethylbenzonitrile oxide to C₁₅ sesquiterpene was observed

Distribution of xanthene dyes in 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) vesicles.

The bacterial cellulose (BC)-chloroaluminum phthalocyanine (ClAlPc) membranes were evaluated as a potential drug delivery system for photodynamic therapy of skin cancer.

Production and purification of recombinant protein/immunization of rabbit and antibody purification/immobilization of antibody on sensor chip/interaction of bacteria with immobilized antibody/analyzing of responses.

We optimized radiolabeling cysteine-based peptides with technetium-99m (^99mTc). In this study, the effect of experimental parameters in the labeling procedure such as type of buffer solutions, pH of media, and type of exchange ligands were optimized toward obtaining maximum labeling yield.

The use of a curve of mobility vs. pH to optimize the optimum background electrolyte (BGE) composition that leads to a reduced analysis time.

A new method to normalize power of fuel cells based on the cost of metals. This method allows the forecasting of power density.

Three new unsymmetrical diarylethenes were synthesized, exhibiting a notable photochromism. Diarylethenes with thienyl/thiazyl unit showed higher photocyclization quantum yield than that with phenyl moiety, which was ascribed to the existing weak N^...S heteroatom-contact.

A series of oxadiazolyl-2-oxoindolinylidene propane hydrazides were synthesized based on hybrid approach. Two compounds from this series exhibited good analgesic and anti-inflammatory activity with better protection compared to indomethacin. These compounds also exhibited good dock score of about -4.44 by the K-nearest neighbors (KNN)-genetic algorithm method.

After the co-doping result in the increasing area of oxidation peak around 3.5 V. At the same time, a shift of reduction peak at 2.5 V towards the right means less internal polarization.

Relative contribution of each factor to the total uncertainty in the determination of boron, phosphorus and sulfur in mineral fertilizer by inductively coupled plasma optical emission spectrometry.

The mobilization of several elements of coal fly ash to end products, washing waters and the effluent of the zeolite two-steps synthesis, was evaluated. The presence of highly toxic elements (As, Cd, Cr, Ni and Pb) in the end products indicates the need for pre-treatment of the ash to ensure a safe zeolite application.

The selective synthesis of (Z)-chalcogenoenynes and (Z,Z)-1,4-bis-chalcogenbuta-1,3-dienes is presented here.

The solvent model density (SMD) model is not able to predict the protic to dipolar aprotic solvent rate acceleration effect for ion-molecule nucleophilic substitution reactions.

Distortion of Pd₄ promoted by γ-alumina cluster (top) and preferential site for adsorption of NO on Pd₄/Al₁₄O₂₄H₆ (bottom).

Comparison between computed confidence intervals for ln k = f(x₁, x₂, x₃) regression coefficients.

Inductively coupled plasma-tandem mass spectrometry (ICP-MS/MS) as an effective tool to overcome double charged interferences from rare earth elements (REEs) on As determination in agricultural inputs.

A new post-metallocene-Ti catalyst with ethylmaltol ligand was synthesized and characterized. This complex was immobilized on different mesoporous supports and investigated in ethylene polymerization reaction giving high density polyethylene.

Iron nanoparticles were prepared from yerba mate tea extract by a green synthetic approach and successfully applied in the degradation of the dye methyl orange.

A mixed-hemimicelles (MHSPE) method coupled with dispersive liquid-liquid microextraction (DLLME) for the isolation and determination of amphetamines from biological samples is developed based on the use of sodium dodecyl sulfate (SDS)-coated Fe₃O₄ nanoparticles prior to the high performance liquid chromatography (HPLC-UV) analysis.

Coacervates made up of reverse micelles of decanoic acid were proposed for the extraction of silver from natural water samples prior to its determination by flame atomic absorption spectrometry (FAAS).

Five anthraquinones in Radix et Rhizoma Rhei could be quantified accurately using featured signals from ¹H nuclear magnetic resonance (NMR), implying that quantitative ¹H NMR represents a feasible alternative to high-performance liquid chromatography (HPLC)-based methods for quantitation of anthraquinones in Radix et Rhizoma Rhei.

In this work, thirteen Mannich bases derived from lawsone were synthesized. Docking studies and evaluation of the antifungal activity were performed.

¹H nuclear magnetic resonance (NMR) high-resolution magic angle spinning (HR-MAS) technique represents an important time saver for identification of new synthetic illicit substances seized by police department.

This study is the first report on the analysis of bio-oil from baru and acuri. The samples produced bio-oils with different compositions.
