We demonstrate the application of a novel smart surface to modulate the orientation of immobilized double stranded DNA (dsDNA) and the conformation of a polymer scaffold through variation in buffer pH and ionic strength. An amphoteric poly(dimethylacrylamide) based coating containing weak acrylamido acids and bases, which are copolymerized together with the neutral monomer, is covalently bound ...

The objective of this research work was to design, develop and optimize the self micro-emulsifying drug delivery system (SMEDDS) of Felodipine (FL) filled in hard gelatine capsule coated with polymer in order to achieve rapid drug release after a desired time lag in the management of hypertension. Microemulsion is composed of a FL, Lauroglycol FCC, Transcutol P and Cremophor EL. The optimum sur...

during storage of eggs, unfavorable changes occur due to exertion of co2 and water vapor from through of crust pinholes. one of the practical methods for preventing or reducing these changes is to use biopolymer-based coatings. in this research, five coating solutions based on carboxymethyl cellulose (cmc) and glycerol as plasticizer, oleic acid (1 and 2% v/v) and antimicrobial agents (potassiu...

This research aims to look into theories about teacher competency, educational background, and training, where the hypothesis claims that background training involvement has a positive link with competence. is an explanatory study seeks explain relationship between characteristics such as participation in competency. With 35 samples, this was conducted on economic teachers at Malang Senior High...

Polymer-modified electrodes were obtained by spin-coating solutions of poly(benzobisimidazobenzophenanthroline) ladder (BBL) and semiladder (BBB) polymers on indium-tin oxide electrodes. An electrochemical study of these films showed reproducible and stable cyclic voltammograms for reduction of the polymer (in the absence of oxygen), the absence of waves for oxidation of the polymer, and brilli...

We designed a study for photodynamic therapy (PDT) using chitosan coated Mg-Al layered double hydroxide (LDH) nanoparticles as the delivery system. A Food and Drug Administration (FDA) approved near-infrared (NIR) fluorescent dye, indocyanine green (ICG) with photoactive properties was intercalated into amine modified LDH interlayers by ion-exchange. The efficient positively charged polymer (ch...

A blue reflective photonic polymer coating which can be patterned in full color, from blue to red, by printing with an aqueous calcium nitrate solution has been fabricated. Color change in the cholesteric liquid-crystalline polymer network over the entire visible spectrum is obtained by the use of nonreactive mesogen. The pattern in the coating is hidden in the blue color dry state and appears ...

The realization of a complete tandem polymer solar cell under ambient conditions using only printing and coating methods on a flexible substrate comprises a fully scalable
