Experimental Study on Nano-Parameters of Styrene-Butadiene-Styrene Block Copolymer Modified Bitumen Based on Atomic Force Microscopy

Three-dimensional study of cylindrical morphology in a styrene-butadiene-styrene block copolymer

When a block copolymer undergoes microphase separation, well ordered microstructures result which give the copolymer unique thermal and mechanical properties. In relating these properties quantitatively to the microstructure, and in devising models for the phase separation, theoreticians have always invoked highly idealized structural elements. However, variations in the actual microstructure m...

Styrene-butadiene-styrene Tri-block Copolymers Modified with Polyhedral Oligomeric Silsesquioxanes

Effective Parameters in Contact Mechanic for Micro/nano Particle Manipulation Based on Atomic Force Microscopy

The effect of geometry and material of the Micro/Nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. Hertz contact model simulation for EpH biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. Then, to val...

Experimental data on compressive strength and durability of sulfur concrete modified by styrene and bitumen

In this data article experimental data on the compressive strength, and the durability of styrene and bitumen modified sulfur concrete against acidic water and ignition are presented. The percent of the sulfur cement and the gradation of the aggregates used are according to the ACI 548.2R-93 and ASTM 3515 respectively. For the styrene modified sulfur concrete different percentages of styrene ar...

Butadiene and Styrene Risks

The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...
