A New Method for the Estimation of Trigonelline in Urine and Foodstuffs
THE recognition of trigonelline as a product of the metabolism of nicotinic acid is due to Ackermann1, who in 1912 dosed dogs with nicotinic acid and found it to be partly excreted as trigonelline. Linneweh and R...

In-Situ Patiterning and Regrowth of InP Based Heterostructures Using a Native Oxide Mask
We have successfully used an ultrathin (20–50 Å ) native oxide layer on the surface of InP as an etch mask for transferring patterns onto the substrate. The oxide mask is grown in situ in O2 atmosphere, and the m...
