In this study, a single-step microfluidic approach is reported for encapsulation of enzymes within microcapsules with ultrathin polymeric shell for controlled release triggered by an osmotic shock. Using a glass capillary microfluidic device, monodisperse water-in-oil-in-water double emulsion droplets are fabricated with enzymes in the core and an ultrathin middle oil layer that solidifies to p...

Resin Concrete uses polymeric resin to replace cement concrete. Four types of polyester resins were identified with Methyl methacrylate as catalyst, calcium carbonate and fly ash fillers along river sand coarse aggregate size 10mm, 6mm used produce Seventy-two trial batches carried out for preliminary investigation targeting compressive strength more than 80 MPa (11.6 ksi) four shortlisted. The...

Polymeric capsules can have an advantage over glass capsules used up to now as proof-of-concept carriers in self-healing concrete. They allow easier processing and afford the possibility to fine tune their mechanical properties. Out of the multiple requirements for capsules used in this context, the capability of rupturing when crossed by a crack in concrete of a typical size is one of the most...

Over the past decade or so, alternative energy plays a pivotal role in addressing challenges posed by nature. Polymer electrolyte membrane fuel cell is one of the promising alternative energy and there has been significant research and technological investments done in this field. The key information and future prospective of the field is energy conversion and storage, both of which are essenti...

Recently, the polymeric micro-fluidic biochip, often called LOC (lab-on-a-chip), has been focused as a cheap, rapid and simplified method to replace the existing biochemical laboratory works. It becomes possible to form miniaturized lab functionalities on a chip with the development of MEMS technologies. The micro-fluidic chips contain many micro-channels for the flow of sample and reagents, mi...

We measured in absorption mode at the Ruthenium K-edge, Ru-Ru and Ru-N distances, in structurally known systems: the Ruthenium dimeric precursor compound, already structurally characterized, the monomeric species of Ruthenium phthalocyanine (adduct) and the polymeric species of Ruthenium phthalocyanine (with bridging oxygen). The film, a candidate for sensor and electrochromic applications, is ...

The dynamic manipulation of colloidal particle shape offers a novel design mechanism for the creation of advanced responsive materials. To this end, we introduce a versatile new strategy for shape control of anisotropic polymeric colloidal particles. The concept utilizes temperature-sensitive absorption of a suitable solvent from a binary mixture. Specifically, increasing the temperature in the...

Poly(methyl methacrylate), PMMA, exhibits different glass transition temperatures, Tgs, according to the configuration of its chain. Consequently, molecular modeling offers an ideal tool to understand from molecular interactions the reasons that give rise to such a difference, and as a matter of fact, to better understand the tricky problem of glass transition. However, an intimately link has t...

We report a novel modification of silicone elastomer polydimethylsiloxane (PDMS) with a polymer graft that allows interfacial bonding between an elastomer and glass substrate to be performed without exposure of the substrate to harsh treatment conditions, such as oxygen plasma. Organic molecules can thus be patterned within microfluidic channels and still remain functional post-bonding. In addi...

Abstract Variations on the processing conditions of conventional methods for polymeric film preparation may allow tuning certain properties. In this work, different casting surfaces and humidity are presented as variables to consider cellulose acetate (CA) using solution method. Specifically, borosilicate glass, soda-lime glass Teflon (PTFE) dishes have been used their influence various propert...
