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.

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.

LiVGe2O6, an anomalous quasi 1D, $S = 1$ system, as revealed by NMR
, 2000 We report the results of $^{7}$Li nuclear magnetic resonance (NMR) studies of LiVGe$_{2}$O$_{6}$, a quasi one--dimensional spin $S = 1$ model system, at low temperatures.

Electrokinetic analysis reveals common conditioner ingredient interactions with human hair
International Journal of Cosmetic Science, EarlyView.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.

A compact design for the Josephson mixer: the lumped element circuit
, 2015 We present a compact and efficient design in terms of gain, bandwidth and dynamical range for the Josephson mixer, the superconducting circuit performing three-wave mixing at microwave frequencies. In an all lumped-element based circuit with galvanically

Nouveaux procédés d'oxydation chimique pour l'élimination des rejets aqueux phénolés [PDF]
, 1992 Pour faire face au problème posé par les rejets aqueux chargés en phénol, deux procédés d'épuration par voie chimique sont proposés. Les deux méthodes font appel au peroxyde d'hydrogène.

Utilisation des lipides : oxydation ou stockage ?
Oléagineux, Corps gras, Lipides, 2008 The stability of body weight and composition requires an equilibrium between the intakes and outputs of energy and macronutrients. Fat mass depends on the equilibrium between the input and output of lipid but also on the metabolic fate of lipids ...

Irrigation and Drainage, Volume 74, Issue 4, Page 1751-1765, October 2025.ABSTRACT Agricultural drainage plays a crucial role in land management and crop productivity but significantly impacts greenhouse gas (GHG) emissions. This study examines the effects of drained and undrained soil conditions on GHG emissions in croplands via a case study in Lincolnshire, United Kingdom.
