use of expanded polystyrene (eps) and shredded waste polystyrene (swap) beads for control of mosquitoes

background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a po­ten­tial alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the im­ma­ture stages by forming a tick layer on the w...

06 Field efficacy of expanded polystyrene fc.indd

Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2 villages in an indigenous malaria area ...

Recycling of Expanded Polystyrene Using Natural Solvents

Introductory lecture: Mechanochemistry, a versatile synthesis strategy for new materials.

Mechanochemistry deals with reactions induced by the input of mechanical energy - for example by impacts within a vibratory ball mill. The technique has a long history with significant contributions from Ostwald, Carey Lea and, notably, Faraday. Mechanochemistry has subsequently seen application in a variety of areas of materials science including mechanical alloying in metallurgy, the synthesi...
