A New Class of Nucleosides. Synthesis, Reactivity and Biological Activity of Keto-Hexose Nucleosides
CHIMIA, 1975 Direct oxydation of sterically hindered hexosyl purines led to keto-hexosylpurines, important synthetic intermediates. The first unsaturated keto-nucleosides have also been obtained by acetylation of the corresponding keto-hexosyl purines.

L’EPURATION TERTIAIRE DES EAUX USEES DE L’INDUSTRIE DE LA CELLULOSE [PDF]
Annals: Series on engineering sciences (Academy of Romanian Scientists), 2010 Les processus de fabrication de la cellulose représentent des sources importantes de pollution tant pour les eaux, que pour l’aire et le sol. La pollution de l’eau est du, essentiellement, aux substances organiques dissous, aux substances en suspension ...

Behandlung photographischer Abwässer. Ein Umweltschutzproblem von wirtschaftlicher Bedeutung
CHIMIA, 1980 The chemical treatment of photographic effluents (eg. oxydation, precipitation) increases the production costs of photographic laboratories and should therefore be considered only as the last step of a series of measures to abate pollution.

International Journal of Cosmetic Science, EarlyView.UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 1093-1102, July 2026.The full‐field X‐ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full‐field and fluorescence modes, hyperspectral XANES mapping.This study ...

CHIMIA, 1969 The oxydation of pyrocatechole-3,5-disulfonic acid by vanadium(V) in acidic solution has been studied spectrophotometrically. Analysis of kinetic data suggests two parallel reaction paths: (a) An initially formed intensely coloured VO2+ substrate ...

Electrokinetic analysis reveals common conditioner ingredient interactions with human hair
International Journal of Cosmetic Science, Volume 48, Issue 2, Page 379-393, April 2026.Novel electrokinetic analysis reveals how cationic surfactant deposition on hair is influenced by chain length and counterion mobility. Longer‐chain surfactants show superior adsorption through enhanced van der Waals interactions, while chloride counterions enable stronger electrostatic interactions.

Oxydation de solutions d’acide iodhydrique par l’air en présence de lumière
CHIMIA, 1972 The reaction 4 HI + O2 →hν 2 H2O + I2 has been studied as a possibility of regeneration of the cathodic fuel in a cell using the cathodic reaction I2 + 2 e- → 2 I-.

Oxydation der mehrwertigen Alkohole [PDF]
Berichte der deutschen chemischen Gesellschaft, 1887 Als Oxydationsprodukte der mehrwertigen Alkohole hat man bisher nur Sauren gefunden; die dabei hochstwahrscheinlich zuerst entstehenden Aldehyde oder Ketone sind aus Mangel an geeigneten Methoden nicht beobachtet, geschweige denn isoliert worden. Eine einzige Ausnahme bildet der Mannit.
