Modified and Unmodified Zinc Oxide as Coagent in Elastomer Compounds

Modified versus Unmodified Ect

MODIFIED VERSUS UNMODIFIED ECT 4 Sir, Apropos the paper of Andrade et al. (April, 2000), I am surprized that the authors have tried to justify the use of unmodified ECT by showing that musculoskeletal complications are not common or serious Tharyan et al. (1993) too have done the same. The problem is not as to whether orthopaedic complications are more or less frequent with this type of treatme...

Zinc and Zinc Compounds

Zinc is an essential element in people’s diet. Too little zinc can cause health problems, but too much zinc is harmful. The U.S. Recommended Dietary Allowance (U.S. RDA) for zinc is 5 15 milligrams a day for humans. Not enough zinc in one’s diet can result in a loss of appetite, a decreased sense of taste and smell, slow wound healing and skin sores, or a damaged immune system. Young men who do...

Electroanalytical detection of pindolol: comparison of unmodified and reduced graphene oxide modified screen-printed graphite electrodes.

Recent work has reported the first electroanalytical detection of pindolol using reduced graphene oxide (RGO) modified glassy carbon electrodes [S. Smarzewska and W. Ciesielski, Anal. Methods, 2014, 6, 5038] where it was reported that the use of RGO provided significant improvements in the electroanalytical signal in comparison to a bare (unmodified) glassy carbon electrode. We demonstrate, for...

Toughening mechanisms in elastomer-modified epoxies

The role of matrix ductility on the toughenability and toughening mechanism of elastomermodified, diglycidyl ether of bisphenol A (DGEBA)-based epoxies is investigated. Matrix ductility is varied by using epoxide resins of varying epoxide monomer molecular weights. These epoxide resins are cured using 4,4' diaminodiphenyl sulphone (DDS) and, in some cases, modified with 10vol % carboxyl-termina...
