A new class of biodegradable anionic surfactants with structures based on 5-alkoxymethylfuroate was prepared starting from 5-hydroxymethylfurfural (HMF), through a one-pot-two-steps process which involves the selective ...

A novel procedure for the preparation of fewlayers boron nitride (BN), either as films or as suspended BN platelets, is presented, based on the pyrolysis of chitosan, which serves both as a matrix to embed ammonium borate ...

A two-dimensional zeolite with the topol. of MWW sheets has been obtained by direct synthesis with a combination of two org. structure-directing agents. The resultant material consists of approx. 70 % single and double ...

[ES] En la actualidad, existe una legislación ambiental muy estricta con respecto al contenido de azufre que pueden contener los combustibles de automoción. La presencia de compuestos de azufre en los combustibles da lugar ...

Graphene oxide promotes the oxidative degradation of -guaiacylglycerol--guaiacyl ether, a lignin model compound, in different solvents including acetonitrile, toluene and water mainly to guaiacol, 2-methoxyquinone, vanillic ...

[EN] In the last few years, important efforts have been made to synthesize so-called "multipore" zeolites, which contain channels of different dimensions within the same crystalline structure. This is a very attractive ...

Pyrolysis of chitosan films containing Au3+ renders 1.1.1 oriented Au nanoplatelets (20 nm lateral size, 3-4 nm height) on a few layers of N-doped graphene ((Lambda) over baru/fl-G), while the lateral sides were 0.0.1 ...

1,5-Benzothiazepines derivatives were obtained first by starting from 1,3-diphenylpropenone derivatives (chalcones) and 2-aminothiophenol by using aluminosilicate solid catalysts. However, diffusional limitations and ...

Recent photocatalytic data for CO2 reduction by H2O using simulated sunlight have shown that, while TiO2 Evonik P25 containing Au nanoparticles (NPs; Au/P25) generates considerably higher amounts of hydrogen than methane, ...
