The Systhesis Of Camphor From Pinene, Edwin W. Newbury
The Systhesis Of Camphor From Pinene, Edwin W. Newbury
Bachelors’ Theses
The increasing demand for camphor for use in the manufacture of cellulose plastics has led to a great amount of investigation of the nature of this valuable substance and as to its synthesis from materials which are readily obtainable without the necessity for sending overseas for them. At present most of the camphor used in the manufacture of celluloid and allied compounds is imported from Japan or Borneo, where it is obtained, in a rather crude and wasteful fashion, from a species of laurel. Some scientifically operated camphor plantations have been started in the United States.. In one such plantation …

Assay Of Copper Matte For Gold And Silver, Walter E. Soest
Assay Of Copper Matte For Gold And Silver, Walter E. Soest
Bachelors Theses
"Ores containing copper, and especially copper matte, have always been very annoying in assaying for the precious metals. In assaying copper matte, and ores containing much copper, by the usual method of scorification, the losses of silver an gold are considerable, owing to the fact that in order to obtain lead buttons, which are soft and free from copper, repeated scorifications are necessary, and moreover it is impossible to obtain lead buttons which are entirely free from copper"--page 1.

White Lead, Evans Walker Buskett
Producer Gas, Edward P. Dwyer
Producer Gas, Edward P. Dwyer
Bachelors Theses
"Producer gas, so named owing to being produced in special forms of apparatus known as Producers. The fuel is decomposed into combustible gases, whereby most of the C is burnt to CO, whilst the H either remains free, or is converted into carburretted Hydrogen. Directly above the grate carbonic anhydride is formed but thus is rapidly converted into carbonic oxide; reaction as follows: CO₂ + C = 2CO.
Amongst these heavy carburetted hydrogen (C₂H₄) is that which principally increases the value of the gas as fuel and the drier the fuel used the more of the gas is produced. A …

Conference Papers
Nowadays, wearable sensors such as heart rate monitors and pedometers are in common use. The use of wearable systems such as these for personalized exercise regimes for health and rehabilitation is particularly interesting. In particular, the true potential of wearable chemical sensors, which for the real-time ambulatory monitoring of bodily fluids such as tears, sweat, urine and blood has not been realized. Here we present a brief introduction into the fields of ionogels and organic electrochemical transistors, and in particular, the concept of an OECT transistor incorporated into a sticking-plaster, along with a printable “ionogel” to provide a wearable biosensor …
