Dipping solutions

A major challenge for outdoor uses of methylammonium lead halide (MAPbX3) solar cells is the poor durability of the perovskite film under humidity. This instability is due to limitations of the dipping or spin coating process in producing MAPbX3 films through a direct reaction between PbI2 and methylammonium iodide (MAI) in an organic solvent. In this study, we devised an eco-friendly and cost-effective method to fabricate MAPbX3 films using an aqueous solution of Pb(NO3)2 and MAI vapour. I

A Mw 6.8 earthquake struck Western Turkey and Eastern Greece that occurred on October 30, 2020 in Kuşadası Gulf. The earthquake epicentre is located north of Samos Island and the focal mechanism solution shows that a normal fault was reactivated. The main shock and aftershock analysis imply that the large earthquake occurred on a north dipping normal fault which might be the western continuation of the Efes Fault in Western Turkey.

The present paper describes the voltammetric analysis of dipyridamole (DIP) at a cheap, disposable pencil graphite electrode (PGE). The working conditions were optimized with regard to the electrode material and the supporting electrolyte. Cyclic voltammetric investigations emphasized that DIP is irreversibly oxidized at the PGE. The electrode process is pH-dependent and controlled by both diffusion and adsorption. For DIP quantitative determination a differential pulse voltammetric (DPV) method in phosphate buffer solution pH 7.00 was developed.

Oranges were sanitized, dried, peeled, segmented and then dipped in citric acid solution (food grade) at 2% (w/v). Citric acid treated and untreated orange segments were packed with different packaging materials i.e., LDPE, PP and PVC pouches under three different gas compositions i.e., Gas composition 1 (G1: 8% O2 + 15% CO2 + 77% N2); Gas composition 2 (G2: 5% O2 + 10% CO2 + 85% N2); Gas composition 3 (G3: 3% O2 + 5% CO2 + 92% N2) using advanced vacuum packaging machine. After packaging, the sealed covers and control samples of orange segments were immediately stored at 50C.

Water loss is the major problem in rambutan which induces the browning of spinterns and ultimately reduces the consumer acceptance. Techniques which slow down respiration and dehydration rate were found to be more effective in increasing overall acceptability of rambutans. The efficacy of several pre-treatments in up regulating consumer acceptance of rambutan (Nephelium lappaceum L.) fruit was examined. Dipping fruits for 5 min in 2 ppm ozonized water comparably reduced the browning of the fruit stored under room temperature (30±2oC; 80-85% RH).

Highly perishable postharvest life of ber fruit is major hindrance towards long storage. Exogenous treatments are essential for delayed or inhibited physiological degrading process which curbs the fruit quality. Hence, a study was designed to evaluate the oxalic acid (OA) treatments effectivity on ber fruit cv. „Gola‟ during storage. Prior to storage fruits were subjected to 10 min dipping in aqueous solution of oxalic acid at different concentrations (2 mM, 4 mM, 6 mM, 8 mM and 10 mM).

In this study, raisin was produced from pre-treated grapes by tray drying method. Grapes were cleaned and soaked in a different type of solutions such as potassium carbonate, olive oil, soy lecithin, and sugar concentration for different immersion time. The pre-treated grapes were then dried in a hot air tray drier at 50°C and airflow 1.0 m/s. Results showed that drying time was varied for pre-treated grapes. The shortest drying time of 61 h) was obtained for those grapes which were dipped in 6.7 % potassium carbonate solution for immersion time of 5 min.

After sorting and pitting, apricots were cut into two halves and dipped in 0.1% citric acid solution to avoid browning. The pulp of apricots was extracted by using plumper. Apricot pulp was heated to get the desired consistency. Low heating was continued and brix were noted after every 20 minutes. Pectin with small amount of nonnutritive sweeteners were dissolved separately and added to the mixture.

Pumpkin belongs to cucurbitaceae family grown widely in tropical and sub-tropical countries. Pumpkins are the sources of various functional compounds such as carotenoids, vitamins, minerals, dietary fibres, etc. Therefore, an attempt was made by drying of pumpkin for production of flour and its quality evaluation during storage. Different pre-treatments were applied to pumpkin shreds to standardize the method for preparation of pumpkin flour on the basis of chemical quality.
