TEM provides high-resolution imaging to directly visualize individual nanoparticles' size, internal shape and crystallinity. Statistical analysis quantifies variations in lattice parameters, crystal structure, size distributions, phase compositions, lattice strains, preferred orientation and lattice volume of these three crystalline nanomaterials. The review highlights the complementary roles of TEM and XRD in comprehensive Ag, Cu and Ti nanocrystalline materials characterization. The crystallographic functional parameters of Ag were 2θ= 38.1° (111), 44.3° (200) and 64.4° (220); for Cu crystal 43.3° (111), 50.4° (200), 74.1° (220), 89.9° (311) and 95.1° (222) and 35.1° (100), 38.4° (002), 40.2° (101), 53.0° (102), 63.0° (103), 70.7° (110), 76.2° (112), 82.3° (201) demonstrated for Ti nanocrystals. The crystallographic predominant plane or Miller indices were also revealed by selected area electron diffraction (SAED) on TEM. The FCC structure of Ag and Cu is shown in larger lattice volumes compared to the HCP structure of Ti and prefer oriented. The degree of crystallinity of Ti, Cu and Ag nanocrystalline materials was observed at 90.0%, 98.0% and 100.0% respectively.

This abstract investigates the effectiveness of treating constipation with salt water after getting out of bed in the morning using the process of osmosis. Constipation is a common bowel problem caused by diet, lifestyle, medications, or other factors that make stool hard or impede the ability to pass it comfortably, affecting people of all ages worldwide. By conducting osmosis, where solute molecules move through a semi permeable membrane from low solute concentration to high solute concentration, salt water treatment softens stool and facilitates bowel movements. This paper presents an overview of treatment protocols, including materials, methods and observational results. Preliminary findings indicate promising results, with participants experiencing increased frequency and ease of bowel movements after consuming salt water. This paper explores the benefits of osmosis in treating constipation and how it works. We discuss the osmosis and their mechanisms of action, as well as their safety and efficacy. Overall, we conclude that osmosis is a safe and effective way to treat constipation and has the potential to change the life style of millions of people across the Globe.","PeriodicalId":8480,"journal":{"name":"Asian Journal of Applied Chemistry Research","volume":"111 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140987769","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}

The role of individual parts such as the semiconductor electrode, counter electrode, photosensitizer, electrolyte, and substrate and their contribution to the overall efficiency (η) of DSSCs are discussed. In addition, parameters such as short circuit current, open circuit voltage, and fill factor used to quantify the efficiency of DSSCs are addressed.  The highest solar-to-electric energy conversion efficiency of 13 % has been achieved using titanium dioxide as a semiconductor electrode, a triiodide system as a redox couple, and platinum counter electrodes. Semiconductors are made up of materials such as glass, carbon, conductive polymers and other metal oxides have lower efficiencies (< 8 %). In addition, synthetic photosensitizers especially ruthenium complexes have higher efficiencies (10-11 %) compared to natural dyes among which the highest efficiency (4.6 %) was achieved using chlorophyll. The performance of natural dyes based on efficiency of the DSSC is generally in the order: chlorophyll > anthocyanins > carotenoids that is highly attributed to their structure which not only dictates electron release and recombination but also attachment to other components. The DSSC performance is not fixed but rather tunable by variations in the components to achieve desired structural and electronic properties such as firm anchorage between the photosensitizer and the semiconductors, the reduction of the energy band gap by incorporation of other metal salts to extend the absorption range and use of additives that prevent electron recombination with the photosensitizer or any hindrances in the electrolyte redox reactions.","PeriodicalId":8480,"journal":{"name":"Asian Journal of Applied Chemistry Research","volume":"30 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141005429","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}

The study aim to synthesize Silver (Ag) nanoparticles from Ficus exasperata (Sandpaper leave) leaves and to determine its antimicrobial effect on bacteria isolates. Silver (Ag) nanoparticles were synthesized from the plant extracts using standard extracting techniques and their presence was verified and confirmed using an ultraviolet-visible (UV-Vis) Spectrophotometer.  A prepared series of silver nitrate (AgNO3) solutions were mixed with the plant extracts at a ratio of 1:1 (v/v) to a total volume of 20ml in a text-tube.  The test tubes were rapped with aluminum foil and heated in a water bath at 60OC for 3 hours and allowed to cool and analyzed using UV-Vis Spectrophotometer. The UV-Vis spectra confirmed the different concentrations of silver nitrate (AgNO3) that produced Ag nanoparticles and their average size was more than 50nm and less than 100nm. The mixture of the leave extract was tested for its antimicrobial activity against gram-positive and gram-negative organisms such as Staphylococcus aureus Bacillus cereus and Escherichia coli respectively. The results showed that the growth of the different bacteria was inhibited by the extracts containing silver nitrate on Staphylococcus aureus and Escherichia coli and not on Bacillus cereus using Ficus exaseprata nanoparticles. Statistical evaluation showed that zones of inhibition on the three bacteria produced by the aqueous leave extracts containing different concentration of silver nitrate (AgNO3¬¬) precursor was significantly different from the silver nitrate (AgNO3) precursor. It were observed that the higher the concentration of the silver nitrate (AgNO3) the greater the zone of inhibition. It can be concluded that Ficus exaseprata leave extracts dope with silver nanoparticles, can produce antimicrobial effects on some microorganisms.","PeriodicalId":8480,"journal":{"name":"Asian Journal of Applied Chemistry Research","volume":"21 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140753367","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}

The physicochemical properties were analyzed to determine their pH, solubility, moisture content, and tensile strength. Functional groups were investigated using FTIR, and the antibacterial properties were evaluated. The results showed that both biofilms with PVA were weakly acidic and insoluble in all solvents. Meanwhile, CoF biofilm contained higher moisture content than the CasS biofilm. CoF biofilms also carried more weight and higher force than CasS biofilm. Hydroxyl, alkyl, and alkene functional groups were identified for both biofilms. Meanwhile, both biofilms showed no inhibitory effect against E. coli, and S. aureus. Therefore, the developed biofilms with PVA showed good physicochemical properties and can be used for packaging applications. The slight acidity can prolong their shelf-life. Moreover, both will not easily dissolve. CoF biofilm comprised more water than CasS but both are still suitable for packaging due to their tensile strength attributed to the presence of the functional groups. However, CasS, CoF, and PVA do not have antibacterial properties. More physicochemical tests, further characterization, and incorporation of antibacterial agents were recommended.","PeriodicalId":8480,"journal":{"name":"Asian Journal of Applied Chemistry Research","volume":"44 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140363855","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}

Al-Zn coated sheets measuring 130 mm x 190 mm coated with masses ranging from 60-150 gm2 were exposed for 2 years. The specimens were collected at periodic intervals following ASTM G1-90 standard method and corrosion products analyzed by Raman spectroscopy, while corrosion rate was determined by weight loss method. Corrosion rate ranged from 0.03 to 0.05 mmpy and increased with decreasing masses coating materials from 150 to 60 (gm2). Diani site recorded higher corrosion due to severe marine conditions characterized by high chlorides, RH of 81%, UV of 12mW/cm2 and a temperature of 27 ℃. Dominant rust constituents were goethite (a-FeOOH) and lepidocrocite (g-FeOOH), while  ferrihydrite and maghemite (a-Fe2O3) were measured at low levels suggesting the influence of suphur dioxide and chloride pollution on  corrosion rate at both sites.
