What are asphalt emulsions and why are they important? They are liquid asphalt cement emulsified in water. They compose of bitumen, water, and an emulsifying agent or surfactant. Asphalt emulsions are integral to the optimum mechanical properties. Modified asphalt emulsions…READ MORE >

Messenger RNA (mRNA) based systems have recently attracted considerable attention for their use in the delivery of functional antibodies and therapeutic proteins. Both viral and non-viral vectors, including liposomes, polymeric nanoparticles, and mRNA-protein complexes, have been studied in clinic. Significant…READ MORE >

Liposomes have been attractive delivery systems for decades due to their composition of natural biological lipids and structural resemblance to cell membranes suggesting metabolic compatibility, low toxicity, biocompatibility and lack of a strong immune response1.  They are comprised of spherical…READ MORE >
