In this study, encapsulation of agarwood oil with non-ionic surfactant, Tween 80 was prepared at critical micelle concentration of 0.0167 % v/v to produce the most stable nano-emulsion in aqueous. The encapsulation has minimized the bioactive compounds degradation in various pH conditions thus prolong their shelf life and maintained its initial oil grade. The oil grading of the prepared samples...

Summary Molybdenum supported on zeolite HZSM-5 is the most studied catalyst for methane dehydroaromatization. However, nature of its catalytic sites and their deactivation mechanisms remain unclear controversial. Here, we report further insights into this system: first, crystal size determines form location active MoCx species, thus performance; second, are preferentially deactivated over acid ...

We show that graphene nano-sheets, when appropriately functionalised, can form self-assembling nanocontainers which may be opened or closed using a chemical trigger such as pH or polarity of solvent. Conceptual design rules are presented for different container structures, whose ability to form and encapsulate guest molecules is verified by molecular dynamics simulations. The structural simplic...

Liposomal drug carriers are nano-scale, spherical particles with a phospholipid bilayer surrounding an aqueous core and are commonly used for chemotherapeutic delivery. Chemotherapy efficacy is limited by toxicity and tumor drug resistance; however, with increased circulation and improved tumor deposition due to the enhanced permeability and retention effect, liposomes increase treatment effica...

Plasmid DNA (pDNA) is expected to be a new class of medicine for treating currently incurable diseases. To deliver these nucleic acids, we developed a liposomal delivery system we have called a multifunctional envelope-type nano device (MEND). In this report, we demonstrate that a MEND containing a pH-sensitive cationic lipid, YSK05 (YSK-MEND), efficiently delivered pDNA via systemic injection,...
