Dynamic Compression Modulus of Expanded Polystyrene Foams.

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

Drug delivery properties of macroporous polystyrene solid foams.

PURPOSE Polymeric porous foams have been evaluated as possible new pharmaceutical dosage forms. METHODS These materials were obtained by polymerization in the continuous phase of highly concentrated emulsions prepared by the phase inversion temperature method. Their porosity, specific surface and surface topography were characterized, and the incorporation and release of active principles was...

Nucleation Effects of Nanoparticles on Microcelluar Polystyrene Foams

Introduction Microcellular foams with cell sizes less than 10 μm and cell densities larger than 10cells/cm [1] are gaining commercial importance as lightweight structural materials. The idea of introducing small bubbles in solid polymers was first proposed by Num P. Suh [2] in 1890s and the rationale was that if the bubbles are even smaller than the critical flaws in the polymer matrix and can ...

Implication of expanded polystyrene and shredded waste polystyrene to control Anopheles spp, Bandar Abbas and Chabahar, Iran

Introduction: Due to insecticide resistance, environmental pollution and difficulty in biological control, usage of conventional larval control measures are not applicable in mosquito breeding places. As part of Integrated Vector Management program, we aimed to asses the effectiveness of two polystyrene beads types for Anopheles spp larvae control under laboratory, semi-field and field cond...
