Electrolytic Chlorogen

appeared a report on Electrolytic Chlorogen by Captain W. Hodgkinson, r.e., and Mr. C. M. Hutchinson, c.i.ii., Imperial Agricultural Bacteriologist of the Agricultural Research Institute, Pusa. The principal objects of this enquiry, which were carried out under the auspices of the Army Department (Simla), were to determine the possibility of preparing in India from indigenous materials and by s...

Electrolytic Chlorogen

Sik.?I have received the enclosed letter from Mr. Hutchinson of Pusa in regard to the remarks on Electrolytic Chlorogen contained in the report of my paper on "The Selection of a Disinfectant" in the May issue of the Gazette. Whilst I am not entirely in agreement with Mr. Hutchinson in his estimation of costs based only 011 a phenol coefficient,? (Lysol, for instance, is extensively used by gyn...

THE MATHEMATICS COLLOQUIUM presents

Phase transitions are one of the most common phenomena, e.g., water and vapor in our daily life, or liquid crystal for a laptop. In the last few decades, extensive explorations have been made on stationary phase transitions, e.g. theory of renormalization group. In contrast, much less understanding is yet available for the dynamics, namely, the evolution of a system undergoing phase transitions...

Electrolytic Tungsten Needle Sharpening

F sharpened tungsten needles are essential tools required for the manipulation of small particles (1, 2, 3). They can be purchased commercially from Fine Science Tools at a cost of roughly $100 for a set of ten needles. Tungsten needles can easily become damaged during routine use, and accidentally bumping the sharpened end of a tungsten needle immediately renders it useless. For laboratories t...
