2. Design and preparation of Janus particles 2.1. Design of Janus particles Janus particles as a class of materials, have a characteristic anisotropic structure, composition and properties and are considered as some of the most complicated colloidal particles in existence. Over the past few decades,...
Narrow molecular weight distribution copolymers of MMA with other alkyl methacrylates have also been obtained and such manipulations enable one to vary polymer physical properties such as glass transition temperature, hardness, heat distortion temperature, and the like. However, for uses such as ...
process. The process uses the bacterium of the genus Clostridium, such as Clostridium acetobutylicum, but others including Saccharomyces cerevisiae, Zymomonas mobilis, Clostridium thermohydrosulfuricum, Escherichia coli, Candida pseudotropicalis, and Clostridium beijerinckii, can be used. Biobutanol can also...
A system for use in bone cement preparation can include a chamber for intermixing a liquid monomer and solid polymer components, a container, a vacuum channel, and a filter. The mixing chamber can be configured to hold a non-liquid, polymer powder component of a bone cement. The container ...
