Research ArticleOpen accessIn the keywordsNON-INVASIVE OPTICAL METHOD FOR EPIDERMAL THICKNESS ESTIMATIONAdrian Pena, Miguel Arronte, Eduardo De Posada et al.A non-invasive method to determine epidermal thickness from the intensity of transmitted visible light is proposed. A simple model for passing light through the epidermis layers, then measuring what is transmitted back out of the surface, is implemented by using the Montecarlo method. Simulations revealed that the transmittance is linearly dependent on the thickness of the epidermis and so demonstrated … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 7,478 accessesView PDFCite
Technical ReportOpen accessIn the abstractCritical Evaluation of Thermal Efficiency in Aerogel Glazing Systems for Energy-Saving ApplicationsErdem CuceAerogels as a thermal superinsulation material possess a unique combination of properties, most notably low densities, and exceptionally low thermal conductivities, stemming from the high-volume fraction of air incorporated within their structure. Aerogel glazing systems have emerged as a promising solution to enhance the thermal performance of building envelopes while maintaining daylighting. With the notable reductions in production cost in … …Energy Research Journal, Vol. 15, Issue 1 · 22 Jan 2026 · 2,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of a Bioflocculant-Producing Strain and Application in Rice Vinegar ClarificationWeilian Hu, Dehui DaiA bioflocculant-producing bacterium S-3# was isolated from fresh sand bones 40-50 cm underground in the desert region of China’s Ningxia Province. It was identified as Paenibacillus sp. based on 16S rDNA sequence along with its biochemical and morphological characteristics. Chemical analysis found that the bioflocculant from S-3# is mainly composed of extracellular polysaccharide. Researchers observed no noticeable change (above 91%) … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 30 Dec 2020 · 5,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical and Structure Analysis of ZnO:Al FilmNeilo Marcos Trindade, Michel Chaves, José Roberto Ribeiro Bortoleto et al.ZnO and ZnO:Al are wide-bandgap semiconductors which have many applications, mainly as transparent conducting films. Thin films of these compounds were deposited onto glass and silicon substrates by RF magnetron sputtering for the investigation of structural and optical characteristics. The XRD results show that the films present wurtzite structure. The formation of a polycrystalline film having a preferential crystallographic orientation … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Oct 2017 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of ZnO:Ga Thin Films Deposited by dc Magnetron Sputtering: Influence of Ga-Doped Concentrations on Structural and Optical PropertiesPutut Marwoto, Edy Wibowo, Dwi Suprayogi et al.ZnO:Ga thin films were deposited on corning glass by dc magnetron sputtering. Influence of Ga-doped concentrations on the structural and optical properties of ZnO:Ga thin films were investigated. The XRD patterns show that the crystallinity of deposited films improved with the increase of Ga concentrations from 1 to 2%, then decrease at 3% Ga concentrations. The optical transmittance of films … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 14 Dec 2016 · 7,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeposition and Characterization of CdS Nano Thin Film with Complexing Agent TriethanolamineK. Manikandan, C. Surendra Dilip, P. Mani, J. Joseph PrinceThe equimolar concentration thin films of Cadmium Sulfide (CdxSx) with the complexing agent TEA were deposited on a glass substrate by the SILAR technique. The crystalline nature with face centered cubic crystal system of the CdS films is determined from X-ray diffraction analysis. The broadened diffraction peaks indicated nano sized particles of the film materials. The surface morphology of the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 8,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Optimization of Plant Extract Loaded Nanoemulsion Mixtures for the Treatment of Inflammatory DisorderMukesh Gohel, Tejal Soni, Lal Hingorani et al.In current study, a nanoemulsion as drug delivery system (NE) of spray dried Boswellia Serrata Extract (BSE) was developed and characterized to compare it in vitro/Ex vivo diffusion with reference formulation. Pseudo-ternary phase diagrams were constructed by phase diagram by aqueous titration method, of which the evaluation method was improved for solubility, Droplet size and transmittance. The formulation of BSE-loaded … …Current Research in Drug Discovery, Vol. 1, Issue 2 · 26 Jan 2015 · 14,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining Optical Constants of Selenium Thin Films using the Envelope MethodNehad M. Tashtoush, Osamah ALkasassbehTwo Selenium thin films were deposited on glass substrates using thermal evaporation technique. The optical constants (refractive index, absorption coefficient and extinction coefficient and energy gap) were calculated using the Transmittance (T) spectrums of the films in the spectral range of 500-900 nm. The envelope method was used to determine optical constants. The calculated refractive index was found to be … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 15 Feb 2013 · 6,337 accessesView PDFCite

Research ArticleOpen accessIn the abstractLand Surface Temperature Retrieval by Using ATCOR3_T and Normalized Difference Vegetation Index Methods in Penang IslandK. C. Tan, H. S. Lim, M. Z. MatJafri, K. AbdullahProblem statement: Many studies have been devoted to establish the methodology for retrieval of LST from single channel algorithm by utilizing Landsat satellite images. However, this method required many atmospheric parameters to retrieve LST. Thus, it is very difficult to acquire the complete information for atmospheric parameters.
