The sample was systematically characterized by Powder X-ray Diffractometer (XRD), Attenuated Total Reflectance (ATR), Field Emission Scanning electron Microscope (FE-SEM), Transmission Electron Microscope (TEM) and Ultraviolet- Diffuse Reflectance Spectroscopic techniques. From the investigations, it is observed that this composite possess the combination of both individual and binary phases. The elongated nanostructures obtained due to the binary phases and spherical shaped nanostructures obtained due to the individual phase were observed from the FE-SEM image. The formation of the nanocomposite has further been confirmed from TEM and HRTEM images. ZTVO nanocomposite possess large surface area of 167.3 m2/g and pore size value around 11 nm. Also, the band gap of the material has been found to be 1.97 eV. Dye-sensitized solar cell (DSSC) has been fabricated using this ZTVO nanocomposite as the photoanode and betalain dye extracted from beetroot (Beta vulgaris) as the natural dye. This simple protocol was formulated at a low cost for the first time for DSSC fabrication and it has attained the efficiency of 3.41%. This better efficiency of ZTVO might be due to larger surface area, presence of pores in addition to smaller band gap.","PeriodicalId":21779,"journal":{"name":"Solid State Technology","volume":"64 1","pages":"1800-1807"},"PeriodicalIF":0.0,"publicationDate":"2021-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47111503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is done by calculating the resistance changes as gas is spread over the sensing layer. This instant response in gas detection helps in various applications such as vehicle breath analyser, breath analyzer, food quality control, etc. The gas sensor uses a micro-hotplate structure made of poly silicone mesh. The sensor holds a very thin conductive titanium film which detects the existence of vapors of ethyl alcohol on it. The temperature produced by the hot-plate influences different factors, such as the film's conductance and the amount of a particular gas adsorbed thereon. When the sensor film is brought to the right boiling point temperature, the residual vapor particles evaporate. We configure the supply voltage (around 3 volts) and evaluate the microheater's uniform temperature profile (619.29 K) along with sensitivity and selectivity for efficient sensing of alcohol gas. For the analysis of gas sensing, we have to equate the sensitivity of ZnO, TiO2 and SnO thin film coating. The concept was implemented using heating joules, thermal expansion and FEM simulation with electric current.","PeriodicalId":21779,"journal":{"name":"Solid State Technology","volume":"63 1","pages":"2915-2923"},"PeriodicalIF":0.0,"publicationDate":"2020-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46412428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data collection was carried out employing interviews and observation methods. Relative themes that emerged from this study were commitment, milestones, physical development, self-discipline, realization, pride and passion, training, competition, camaraderie, support, and aspiration. Curiosity and peer influence were the main factors that led participants to join the arnis team, and the rigors of the training changed their perspective towards the fulfillment of curricular and co-curricular objectives. Significant benefits from joining Arnis have been highlighted, such as sound health, asthma healing, physical and character development, and other positive attributes have been enhanced. Their aspiration as senior practitioners would be to share the kind of discipline, advancement, and expertise they have achieved with the beginners to express gratitude to the team. Furthermore, it was revealed that the ideal peer influence would lead to something beneficial, such as an affiliation to a sport like Arnis. At the same time, the loco parentis is essential for the role modeling to student-athletes who have been successful in managing difficulties due to genuine friendship and love.

The study highlights the growth of Okra, one of the most common, easy-to-grow, and nutritious vegetables for home-grown container gardening. Chicken manure, vermicompost, and liquid bio-inoculants (FAA, FFJ, and CalPhos) were the organic fertilizers used to distinguish the growth effect on containerized Okra labeled as Groups A, B, and C and observed for eight (8) weeks. The result has confirmed that the growing effect of chicken manure as a basal fertilizer on Group A was satisfactory. Interestingly, the effect of vermicompost as basal fertilizer in Group B was unsatisfactory, whereas the effect of liquid bio-inoculant as basal and foliar fertilizer was very satisfactory. Containerized plants rely mainly on growers for irrigation and fertilization due to the restricted movement of the root system. Home container gardening has been strongly encouraged in urban areas, as harvesting is within reach of family use. The report addresses much of growing containerized Okra in home gardening. The scope of the study is limited only to the observation of growth rates of Okra plants during the vegetative phase. Future research efforts may be undertaken to identify a different outcome of such organic fertilizers in the form of foliar fertilizer. Due to its superior effect on containerized Okra plants, the use of liquid bio-inoculants as basal and foliar fertilizers for home gardening is recommended.","PeriodicalId":21779,"journal":{"name":"Solid State Technology","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43898161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
