Deltamethrin, a member of the pyrethroids, one of the safest classes of pesticides, is among some of the most popular and widely used insecticides in the World. Our objective was to synthesize an oxabicyclolactone 6 and five novel pyrethroids 8–12 from readily available furfural and D-mannitol, respectively, and evaluate their biological activity against four insect species of economic im...

Correction for ‘A bifunctional hierarchical core–shell Mo 2 C@ZnIn S 4 Schottky junction efficient photocatalytic H -evolution integrated with valuable furfural production’ by Jian Yang et al. , Inorg. Chem. Front. 2023, https://doi.org/10.1039/d3qi01422c.

SiO 2 @Au@TiO core–shell catalysts present excellent activity, selectivity and stability in the base-free oxidation of furfural, showing a hundredfold catalytic activity increase with respect to conventional @TiO @Au supported catalysts.

Abiu (Pouteria caimito) merupakan tanaman tropis eksotis yang mempunyai banyak manfaat untuk kesehatan. menarik karena kandungan senyawa bioaktifnya beragam sehingga perlu dilakukan penelitian terhadap berbagai bioaktif terkandung pada masing-masing bagian abiu. Tujuan dari ini adalah mengidentifikasi dan mengevaluasi ekstrak beberapa abiu serta manfaatnya. Penelitian menggunakan lima (5) yaitu...

Twenty-five Saccharomyces cerevisiae strains were screened for the highest sugar tolerance, ethanol-tolerance, ethanol production, and inhibitor resistance, and S. cerevisiae KL5 was selected as the best strain. Inhibitor cocktail (100%) was composed of 75 mM formic acid, 75 mM acetic acid, 30 mM furfural, 30 mM hydroxymethyl furfural (HMF), and 2.7 mM vanillin. The cells of strain KL5 were tre...

The increasing interest in the composition of nucleoproteins has emphasized the need for more specific methods of assay of constituent nucleic acids. In a previous paper (1) a method was reported for the assay of deoxyribonucleic acid (DNA) in tissues and microorganisms based on the reaction of p-nitrophenylhydrazine with deoxyribose following hydrolysis of the biological material with 5 per ce...

the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

the aim of this study was to degrade furfural by a new nanotube system. to degrade some organic pollutants as well as to reduce the amount of furfural which is a well-known pollutant in oil industry, the photocatalytic process along with ultraviolet (uv) irradiation may be employed. in this study, the uv/tio2/pd system in which the nanoparticles of palladium doped into the titanium dioxide was ...

Cyclodextrins act as growth controllers in the synthesis of PVP-stabilized Ru(0) nanoparticles, leading to enhancement of the catalytic activity in the hydrogenation of furfural.
