AB  - Freeze drying was compared with spray drying regarding feasibility to process wild thyme drugs in order to obtain dry formulations at laboratory scale starting from liquid extracts produced by different extraction methods: maceration and heat-, ultrasound-, and microwave-assisted extractions. Higher total powder yield (based on the dry weight prior to extraction) was achieved by freeze than spray drying and lower loss of total polyphenol content (TPC) and total flavonoid content (TFC) due to the drying process. Gelatin as a coating agent (5% w/w) provided better TPC recovery by 70% in case of lyophilization and higher total powder yield in case of spray drying by diminishing material deposition on the wall of the drying chamber. The resulting gelatin-free and gelatin-containing powders carried polyphenols in amount ~190 and 53–75 mg gallic acid equivalents GAE/g of powder, respectively. Microwave-assisted extract formulation was distinguished from the others by a higher content of polyphenols, proteins and sugars, higher bulk density and lower solubility. The type of the drying process mainly affected the position of the gelatin-derived -OH and amide bands in FTIR spectra. Spray-dried formulations compared to freeze-dried expressed higher thermal stability as confirmed by differential scanning calorimetry analysis and a higher diffusion coefficient; the last feature can be associated with the lower specific surface area of irregularly shaped freeze-dried particles (151–223 µm) compared to small microspheres (~8 µm) in spray-dried powder.

AB  - The organo-inorganic perovskites are materials that have recently revolutionized the field of
photovoltaics due to their low-cost fabrication and high optical absorption. The hybrid organoinorganic perovskite absorbs the visible part of the spectrum resulting in the creation of electron-hole pair. To decrease the recombination of charge carriers, the construction of solar cells requires the existence of separate layers for holes and for electrons. TiO2 is usually used as an electron transport layer because its conduction band (CB) lies under the CB of perovskite. In that way, electrons diffuse from CB of perovskite to CB of TiO2. For these experiments, TiO2 nanotubular structure was used as an electron transport layer due to its advantages compared to nanoparticular TiO2. TiO2 nanotubes can provide a one-dimensional transmission channel for the charge carriers, so it will reduce the recombination rate of the carriers and provide a channel for fast carrier transport. However, there is a problem with the contact surface between perovskite and TiO2 nanotubes. The aim of this study is to increase the contact surface of perovskite and TiO2 nanotubes by filling the nanotubes with perovskite material in order to improve electron transport. Methylammonium lead bromide perovskite (MAPbBr3) was deposited on anodically synthesized TiO2 nanotubes which were annealed at 450 °C for 1 h. After degassation of the sample under high vacuum for 3 h at 200 °C, the cooled sample was put in a solution of MAPbBr3 in dimethylformamide (DMF) and it was treated with inert gas (N2), which enabled the filling of the nanotubes with perovskite material to some extent. FESEM and XRD analyses were used for morphological and chemical characterization of the sample. The diffuse reflectance spectroscopy measurement of the sample proved that deposition of MAPbBr3 improves the absorption properties of TiO2 nanotubes. By measuring the I-V characteristics of the sample in the dark and under visible light, a hysteresis curve was obtained.

AB  - In this study, development of folic acid-loaded liposomes using a basic amino acid, histidine as a solubilizing agent for folic acid was presented, which tackled the poor solubility of this vitamin. The effect of the liposomal membrane modifiers, cholesterol and SPAN 20 on the characteristics of the final formulations was examined. Liposomes prepared from a commercially available purified soybean lecithin (Phospholipon 90G) by proliposome method were between 503 and 877 nm in average diameter, where cholesterol induced enlargement and SPAN.20 reduction of vesicles. High encapsulation efficiency of 84% and drug loading of 0.123 mg g−1 were achieved, irrespective to the composition. According to AFM images, folic acid-loaded liposomes of a fraction with a nano size were flattened compared to globular empty liposomes. FTIR analysis revealed possible interactions between phospholipids and histidine, while DSC study suggested interactions between folic acid and lipids during heating. Release study done by a Franz diffusion cell showed prolonged release of folic acid from liposomes and the release rate was determined by folic acid solubility.

AB  - In this study, development of folic acid-loaded liposomes using a basic amino acid, histidine as a solubilizing agent for folic acid was presented, which tackled the poor solubility of this vitamin. The effect of the liposomal membrane modifiers, cholesterol and SPAN 20 on the characteristics of the final formulations was examined. Liposomes prepared from a commercially available purified soybean lecithin (Phospholipon 90G) by proliposome method were between 503 and 877 nm in average diameter, where cholesterol induced enlargement and SPAN.20 reduction of vesicles. High encapsulation efficiency of 84% and drug loading of 0.123 mg g−1 were achieved, irrespective to the composition. According to AFM images, folic acid-loaded liposomes of a fraction with a nano size were flattened compared to globular empty liposomes. FTIR analysis revealed possible interactions between phospholipids and histidine, while DSC study suggested interactions between folic acid and lipids during heating.

AB  - We fabricated Sn-doped TiO2 nanotubular film via annealing of anodized TiO2 nanotubes grown on F–SnO2 (FTO) glass. Annealing was carried out at 500 °C in ambient air. Anatase crystal structure was achieved with no change in nanotubular morphology in respect to as-anodized amorphous TiO2 nanotubes. The X-ray photoelectron spectroscopy analysis revealed Sn on the surface of TiO2 film, following the thermal treatment, probably caused by the diffusion from FTO glass. Depth profile examination of the film chemical composition was conducted by elastic recoil detection analysis, which showed that in addition to the diffusion of Sn from FTO, diffusion of Ti to FTO concurrently occurred. Thus, a higher concentration of Sn was found at the bottom of the tubes, while a lower concentration was present on the tubes’ surface top. This explains the improved optical response revealed by a diffuse reflectance spectroscopy. The absorption enhancement demonstrated that Sn-doped TiO2 film was efficient in the degradation of methyl orange dye under visible light.
