Novel Fe₃O₄/Ni-Al-Ce LDH/Bi₂WO₆ composites were prepared through a facile method. The composites showed high efficiency and stability in the decolorization of an organic pollutant; the decolorization rate of MO was 87% within 60 min under visible-light irradiation.

Weinmannia tomentosa Don, is a tropical tree of Cunoniaceae family that grows at high Andean and humidity forest zones in Colombia, is known as Encenillo is source of monofloral honey that bears that name. Physicochemical and volatile compounds are evaluated in this research.

A H225M Helicopter from Brazilian Air Force deploys conventional flares during a flight.

Suspended particulate matter was sampled with a sediment trap (45 µm mesh) installed in estuarine drainage channels. The traps collected enough material to perform geochemical analyses (metals, mineralogy, granulometry) during each season.

Schematic diagram of modified electrodes. Theoretical model of catalytic processes at modified electrodes are discussed. Mathematical solution of nonlinear reaction diffusion equations were obtained.

Three fungal strains were tested as possible polyurethane biodegradation agents. Cultures were carried out in liquid state with minimal mineral medium and polyurethane biodegradation was assed by infrarred and thermogravimetric analyses.

VOCs from Albonectria rigidiuscula fungus produced in different culture media were extracted by HS-SPME and analyzed by GC-MS.

Reaction of 2-acetylpyridine with alkyl/aryl halides: An effective approach towards syntheses of 2-acetylpyridine derivatives.

Considering the evolution of environmental processes in the management of agroindustrial residues to reuse them, this application in Deoxynivalenol degradation, develop clean technologies which do not use products that harm the environment.

A number of fungi can degrade lignocellulosic substrates through a rich enzymatic arsenal and demonstrate potential to mycoremediation.

This review highlights recent examples of hydroamination developments, employing unsaturated compounds (alkenes, alkynes and allenes) and amines, selected applications on total synthesis are also presented.

An alternative simple, precise, rapid and low-cost method for determination of hydrochloride tetracycline in pharmaceutical formulations, based on conductometric titration using silver nitrate as titrant.

Using the concepts of constructive learning, student interaction and daily experience on the teaching side and introduction to chemical engineering, mass transfer and unit operations on the engineering side we can reach the activity proposed, named "coffee operation".

Exploring the relationship of the geometric properties of fullerenes and establishing a dialogue between the teaching of mathematical concepts and chemical.
