Abstract: An example hybrid power system includes a mobile platform comprising: a generator set comprising: a reciprocating engine configured to convert natural gas into rotational mechanical energy; and a generator configured to convert rotational mechanical energy sourced from the reciprocating engine into electrical energy; an electrical energy storage system (ESS) configured to store electrical energy; an electrical motor configured to convert electrical energy sourced from a combination of the generator set and the ESS into rotational mechanical energy; and a pump configured to operate using rotational mechanical energy sourced from the electrical motor.

Abstract: Non-crosslinked derivatives of oligo/polysaccharides of formula wherein: X is OH, O?M, NH—R1, O—R1; M is an alkaline or alkaline-earth metal, transition metal, or cation containing a quaternary nitrogen atom; Y is H or R2; R1: the residue of an oligo/polysaccharide; R2: the residue of a C1-C4 linear chain aliphatic carboxylic acid or citric acid; provided that at least one X is NH—R1 or O—R1, while the other two X are present in acid (OH) or salified form (OM).

Abstract: Disclosed are acid polysaccharides characterized by the concomitant presence of alcohol groups esterified with butyric and formic acids.

Abstract: Disclosed are polysaccharides containing residues of glucosamine or galactosamine in the repetitive unit, characterized by the presence of esters on the hydroxyls or amides on the amine functions, with lipoic acid or with mixtures of lipoic acid and formic acid.

Abstract: Acid polysaccharides characterized by the concomitant presence of partial esters with non-polysaccharide carboxylic acids and esters between the acid groups of the initial polysaccharide and the alcohol groups of the repetitive units, with the formation of crosslinking among the polysaccharide chains.

Abstract: Non-crosslinked derivatives of oligo/polysaccharides of formula I, wherein: X is OH, OM, NH—R1, O—R1; M is an alkaline or alkaline-earth metal, transition metal, or cation containing a quaternary nitrogen atom; Y is H or R2; R1: the residue of an oligo/polysaccharide; R2: the residue of a C1-C4 linear chain aliphatic carboxylic acid or citric acid; provided that at least one X is NH—R1 or O—R1, while the other two X are present in acid (OH) or salified form (OM).

Abstract: Acid polysaccharides characterised by the concomitant presence of partial esters with non-polysaccharide carboxylic acids and esters between the acid groups of the initial polysaccharide and the alcohol groups of the repetitive units, with the formation of crosslinking among the polysaccharide chains. Process for the preparation of these derivatives comprising the reaction, in homogenous phase in the protic, polar solvent formamide, of the salt of a monovalent inorganic cation of the selected carboxylated polysaccharide with an anhydride of an alkylcarboxylic acid in the presence of a basic catalyst containing an atom of trisubstituted nitrogen. The formamide hydrolysis leads to the formation of a formate ester.

Abstract: A new class of polysaccharides containing carboxylic groups selectively substituted with halogens on the carbon atom on position 6 of the glicopyranosidic residue and the procedure to obtain these derivatives is therein described. The procedure entails the halogenation of carboxylated polysaccharides with alkyl aryl sulfonyl-halides in organic solvent. The products of this invention can be used as substrates in synthesis where the reactive site is the carbon that binds the halogen. Moreover, they can be used in the medical-diagnostic field.
