Beiträge zur kalorimetrischen Humusbestimmung im Boden
Agricultural and Food Science, 1954 In der vorliegenden Untersuchung wurden einige wichtige bisherige Verfahrensweisen, den Humus durch die Oxydation in Chromschwefelsäurelösungen zu bestimmen, verglichen und kritisiert. Auch der Mechanismus der Oxydation des Humus wurde u.a.

, 2017 Ga$_{0.51}$In$_{0.49}$P is a promising candidate for thermally tunable nanophotonic devices due to its low thermal conductivity. In this work we study its thermo-optical response. We obtain the linear thermo-optical coefficient $dn/dT=2.0\pm0.3\cdot 10^{-

Frontiers in Chemistry, 2018 The major challenge for the pyrolytic conversion of lignocellulosic materials into crude bio-oil is the poor quality of the final product. Several strategies (addition of solvents, production of emulsions, and extraction with biodiesel) have been studied

ChemElectroChem, Volume 11, Issue 5, March 1, 2024.In this article, the electrochemical behaviour of some substituted quinones (dichloro‐; dimethyl‐; phenyl) is revisited in aqueous media using chronoamperometry, cyclic and steady‐state voltammetry. In particular, the calculation of the number of electrons involved in the hydroquinone/quinone couple may be distorted due to kinetic limitations. A simple

Measurement of the Casimir force between parallel metallic surfaces [PDF]
, 2002 We report on the measurement of the Casimir force between conducting surfaces in a parallel configuration. The force is exerted between a silicon cantilever coated with chromium and a similar rigid surface and is detected looking at the shifts induced in
