A history of pest control measures in the anthropology collections, national museum of natural history, smithsonian institution
TL;DR: Since the mid-19th century, various pest eradication techniques have been employed on the anthropology collections at the National Museum of Natural History, Smithsonian Institution as mentioned in this paper, and these techniques are reviewed, and pesticide and fumigant use by early collectors and later collections management staff is documented.
Journal ArticleDOI
The characterization of pigments based on carbon
TL;DR: In this paper, the main features, molecular structures and physical and chemical properties of these carbon types, so far as they are relevant to pigment studies, are reviewed in outline and some better-known pigments based on carbon are summarized, with an indication of which form or forms of carbon each contains.

‘Lead white’ in Japanese paintings
TL;DR: In this paper, the Freer collection of Japanese paintings of the twelfth to the sixteenth centuries has been determined, and basic lead carbonate (lead white) was found in 12 out of 13 Chinese paintings and in all three Korean paintings.
Journal ArticleDOI
Narration and Legacy of Important Chemical Spot Tests in Forensic Investigation.
TL;DR: The outlook and likely impact of these tests on the expansion of scientific investigation and legacy and technical details of selected spot tests used in solving crime are described.

New Specific Test for Calcium
TL;DR: It was found that glyoxal bis[2-hydroxy-anil] is a sensitive reagent for calcium, and the test described is specially suited to detect calcium oxide in a mixture of other colouries oxides, as well as to detectcium in pharmaceutical preparations.

A.D. Matthews,J P. Kiley +1 more
TL;DR: In this article, an anion exchange scheme has been developed for the preconcentration and almost specific separation of microgram and sub-microgram amounts of thallium in natural waters.
Journal ArticleDOI
Neue Wege zur Bestimmung und Trennung der Metalle mit Hilfe von o-Oxychinolin
TL;DR: In this article, a study of Hydrocarbonaten in Carbonate durch Erhitzen wurde bei verschiedenen Temperaturen zwischen 100° and 700° untersucht.
Journal ArticleDOI
Modification of the curcumin method for low level boron determination
TL;DR: A simple modification of the curcumin spectrophotometric determination of boron has been developed in which the acid required to develop the colour is destroyed with ammonium acetate, thus eliminating the need for dilution to large volumes.
