Pollen analysis is a commonly used method to interpret vegetation and environmental change. The standard pollen preparation technique in minerogenic sediments involves the use of hydrofluoric acid (HF) which highly toxic. Currently European legislation requires that hazardous chemicals should be substituted with less or non-toxic if possible. In present paper authors introduce safer method, bas...

Catalyst is the key for hydrodeoxygenation (HDO) of lignin derivatives to produce alkyl aromatics and cycloalkanes, components 100% sustainable aviation fuels (SAF). Mono bi-functional catalysts nickel (Ni) heterophosphotungstic acid (HPW) supported on SBA-15 carbons were prepared, characterized evaluated HDO derived trans-anethole. The structure was intact but its surface area pore volume decr...

Equations that can be used for partition coefficients of both neutral molecules and ions have been revised, and the term that is specific to ions has been re-evaluated. A new method has been devised for the determination of partition coefficients from water to organic solvents for carboxylate anions that is based on the variation of pK(a) for carboxylic acids with solvent. Using these partition...

A new efficient and practical method for the room-temperature reduction of aromatic nitro compounds employing FeSO4. 7H2O, NaBH4, H3PW12O40 system in H2O under mild conditions is reported. The method is simple, inexpensive, easily scaled-up and applicable for the large scale preparation of different substituted anilines.
