Synthesis and characterization of ZnO-graphite nanocomposite

Publication date: Available online 16 November 2019Source: Materials Today: ProceedingsAuthor(s): K. Sowri Babu, V. Himamaheswara Rao, D. Demudu BabuAbstractThe preparation of ZnO-graphite nanocomposite in a novel route by two step process is reported in this paper. In the first step, ZnO nanoparticle solution is prepared by sol-gel method. In the next step, certain quantity of as prepared ZnO nanoparticle gel is added to the graphite powder and grinded for sufficient time to drive the ZnO nanoparticles into the pores of graphite. The powder prepared by the above process was annealed at different temperatures from 500 °C to 800 °C to obtain ZnO-graphite nanocomposite. Scanning Electron Microscope (SEM) pictures showed ZnO nanoparticles of uniform size (≈20 nm) distributed in the graphite matrix. This nanocomposite is further characterized by using X-Ray diffraction and Raman spectroscopy and the results were discussed in detail.

Abstract The main constituents of the Euterpe oleracea Mart., Arecaceae, fruits (a çaí) are anthocyanins. This paper aimed to standardize the extraction process and characterize an anthocyanin-rich dry extract obtained from this fruit. A 23 full factorial design was used. The volumes of ethanol 92% and acetic acid and the extraction time were used as factors. Total solids and an thocyanins content were used as feedback. The dry extract was obtained by freeze-drying. The content of anthocyanins was determined spectrophotometrically. Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimeter, Th...

Primary leiomyosarcoma of the bronchus is an extremely rare malignant neoplasm. A 29-year-old man presented with persisting cough and sputum over 1 month. Unenhanced and contrast-enhanced chest CT showed a nodular lesion in the main bronchus of the left lower lobe and multiple enlarged lymph nodes in the mediastinum. Preoperative staging 18F-FDG PET/CT scan displayed a hypermetabolic lesion of the known nodule and mild FDG uptake of mediastinal lymph nodes. The histological examination confirmed bronchial leiomyosarcoma and reactive hyperplasia in lymph nodes.

Microstructures of the joint were analyzed by optical microscopy, scanning electron microscopy, transmission electron microscope and X-ray diffraction. The tensile strengths of the joint were also measured. The laser was focused on the SS side of the joint, which joined the SS and Cu by fusion ...

Authors: Ahuja K, Sotoudeh H, Galgano SJ, Singh R, Gupta N, Gaddamanugu S, Choudhary G Abstract The skeleton is overall the third most common metastatic site after the lungs and liver. Accurate diagnosis of osseous metastasis is critical for initial staging, treatment planning, restaging, treatment monitoring and survival prediction. Currently, 99mTc-methylene diphosphonate (99mTc-MDP) whole-body scan is the cornerstone of imaging to detect osseous metastasis. Though 18F-sodium fluoride (18F-NaF) was one of the oldest medical tracers but was replaced by other tracers until recently, owing to its physical properties...

Authors: Brindhaban A Abstract Rationale: Radiation dose to patients from imaging modalities are measured or calculated to assess the risk of the procedure and compared it to the benefits. Periodic review of image acquisition methods and radiation dose used are essential part of procedure optimization in medical imaging. The aim of this study was to estimate patient radiation dose from single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) using computed tomography (CT) images for attenuation correction. Methods: SPECT and CT image acquisition parameters such as, administered activity...

Authors: Sarikaya I, Sarikaya A Abstract Positron emission tomography (PET) imaging, particularly oncologic applications of fluorine-18 fluorodeoxyglucose (18F-FDG), has become a routine diagnostic study. To better describe the malignancies, various PET parameters are used. In 18F-FDG PET studies, maximum standardized uptake value (SUVmax) is the most commonly used parameter to provide a measurement of the metabolic activity of the tumor. In obese patients, SUV corrected by lean body mass (LBM) (SUL or SUVSUL) and in pediatric cases, SUV corrected by body surface area are recommended. Metabolically active tumor vol...
