Abstract: The present disclosure relates to The present disclosure relates to a powder of solid material particles comprising at least Li, P and S elements, characterized in that the thiol to carbonate surface groups ratio of the particle surface is less than 2, as measured by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) on a Bruker FTIR (MIR) Vertex 70 spectrometer. The present disclosure also relates to a process for preparing such powder, as well as to the use of such powder for notably manufacturing solid electrolytes or battery articles.

Abstract: The present invention relates to a process for preparing natural raspberry ketone, comprising a step (a) of bioconversion of p-coumaric acid allowing the preparation of p-hydroxybenzaldehyde, a step (b) in which the p-hydroxybenzaldehyde obtained on conclusion of step (a) is condensed with acetone to allow the formation of p-hydroxybenzalacetone, a step (c) in which the p-hydroxybenzalacetone obtained on conclusion of step (b) is converted into raspberry ketone by bioconversion or biocatalysis.

Abstract: Provided are polymers obtained by radical copolymerization of a mixture of (1) acrylic acid; (2) methacrylic acid; and (3) at least one allylcatechol selected from 4-allylbenzene-1,2-diol, 3-allylbenzene-1,2-diol and mixtures thereof. The polymers are especially useful for treating a metallic surface intended to be coated by a paint, a varnish or an adhesive. Also provided are methods of coatings making use of this polymer P, compositions comprising the polymer P and useful for these methods, and the obtained coated materials.

Abstract: The present invention relates to a process for purifying a fermentation must (M), obtained via a biotechnological process, comprising biomass and vanillin or derivatives thereof, said purification process comprising:



(a) a step of separating the biomass of a fermentation must (M) from an aqueous stream (A1) comprising vanillin or derivatives thereof,
(b) at least one step of liquid/liquid extraction of the aqueous stream (A1) comprising vanillin or derivatives thereof, said extraction step allowing the separation of an aqueous stream (A2) and an organic stream (O1) comprising vanillin or derivatives thereof,
(c) at least one step of concentrating the organic stream (O1) to obtain an organic stream (O2) in which compounds with a boiling point lower than that of vanillin or derivatives thereof are separated from said organic stream (O1),
(d) at least one step in which compounds with a boiling point higher than that of vanillin or derivatives thereof are separated from an organic stream (O2) comprising vanillin or derivatives thereof to obtain a stream (O3),
(e) at least one step of crystallizing the vanillin or derivatives thereof contained in the stream (O3).
