Fundamental insights in PLGA degradation from thin film studies

Studies Based on Preparation, Physical Characteristics, and Cellular Pharmacological Activities of Thin PLGA Film Loaded with Geniposide

In this primary study, thin polylactic-co-glycolic acid (PLGA) film loaded with geniposide was first prepared and demonstrated on both physical and pharmacological aspects for its potential application on drug-eluting vascular stents. Physical parameters of geniposide-loaded thin film, such as crystal structure, molecular spectral characteristics, and release behavior in the whole process were ...

Light-induced Degradation of Thin-film Microcrystalline Silicon Solar Cells

This paper evaluates the stability of a pin and a nip dilution series of microcrystalline silicon solar cells when exposed to white light (AM 1.5-like spectrum). Variation of electrical parameters and defect-related absorption is investigated as a function of light soaking and annealing steps. Cells of medium crystallinity show less than 10% reversible relative efficiency loss after 1000 hours ...

Modelling and Degradation Characteristics of Thin-film CIGS Solar Cells

Proton-induced Degradation of Thin-film Microcrystalline Silicon Solar Cells

This paper investigates the stability of dilution series of pin and nip microcrystalline silicon solar cells under low-energy proton irradiation (E = 405 keV). Variation of electrical parameters, defect-related absorption and Urbach parameter are investigated as a function of irradiation and annealing steps. Highly microcrystalline cells show a relative efficiency loss of up to 80 % after proto...

TiO2 Thin Film: Preparation, Characterization, and its Photocatalytic Degradation of Basic Yellow 28 Dye

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...
