This paper presents the joint effect of strain- and doping-induced band gap change in Sn1−xMnxO (0 ≤ x 0.05) nanoparticles. In addition, an effort was made to understand Mn doping on structural optical properties SnO2. X-ray diffraction analysis showed a tetragonal structure unit cell volume decreased slightly with Mn4+ content. The Mn:SnO2 are spherical shaped particles size ranging from 7.7 13.8 nm as calculated by transmission electron microscopy, Scherrer's formula Willamson–Hall plot....

The paper reports the structural and optical studies of Mn doped SnO2 nanoparticles. samples were prepared by chemical co-precipitation technique with three compositions (1, 3 5 mol%). Studies x-ray diffraction transmission electron microscopy revealed tetragonal structure average particle size in range 7-12 nm. UV-Vis-DRS spectroscopy blue shift band gap energy. has increased concentration which can either be due to quantum confinement or charge transfer transitions between conduction...

Osteochondromas are benign osteocartilaginous tumours, which developmental abnormalities rather than actual neoplasms. The lesser trochanter is an extremely rare location for a solitary osteochondroma, and depending on the tumour’s size, patient can exhibit various symptoms, including limited range of motion. This case study describes instance osteochondroma identified managed using excisional biopsy following Ludloff’s approach. With intraoperative fluoroscopy, we could accurately outline...

Mycobacterial infection of the upper extremities is rare with elbow joint being most frequently affected accounting for 2- to 5 % all skeletal localizations. Diagnosis paramount importance in tuberculosis because delay analysis could prime serious difficulties.We describe a presentation 38- year- old male joint. Massive swelling forearm subcutaneous collection without any significant involvement muscles has rarely been reported. This case will be addition literature respect clinical...

Two sets of Ni0.5Co0.5Fe2O4 ferrites were synthesized using sol-gel method. Both the samples heat treated at different temperatures. The effect sintering treatment analyzed on structural and magnetic properties. X-ray diffraction (XRD) scanning electron microscope (SEM) used for analysis. Alternating gradient magnetometer (AGM) is measurements. In analysis, grains size calculated Debye - Scherrer's formula Williamson-Hall (W-H) plot. From both techniques, grain found nearly same increased in...

Pure and Pd doped (1, 3 5 mol%) SnO2 nanoparticles were synthesized by chemical co-precipitation method. Structural analysis with HRTEM XRD confirm the tetragonal structure a grain size ranging from 7 to 13 nm. The decreased increase in concentrations. DRS showed blue shift absorption edge band gap concentration of highest doping 5mol% was found be 4.17 eV. presence confirmed EDX analysis. relationship between dopant structural optical properties Pd: are discussed.

Bilateral proximal fibular head prominence is a rare case of chronic knee pain and can befound in isolation or as part multiple ligamentous bony injuries. There fibula on clinical examination with tenderness palpation. Radiological investigation confirm the diagnosis;in our patient, both plain radiograph MRI magnetic resonance imaging (MRI) were performed. helps assessment intrinsic ligament, well course common peroneal nerve. The prominent excision was performed successfully under general...

Although trauma involving distal radioulnar joint due to fall on the outstretched arm is a common injury pattern, Articular isolated fractures of ulna without coexistent radius fracture are extremely rare.We report 19-year-old male who presented at center after from two-wheeler with pain and swelling his right forearm wrist. After an inconspicuous X-ray in two planes, computed tomography (CT) scan was performed detected intact joint. The patient treated closed reduction K-wire fixation full...

Resumo Objetivo A curetagem estendida com adjuvantes de tumores células gigantes do osso está associada a uma menor taxa recidiva da neoplasia e à preservação articulação adjacente. Este estudo foi feito para estimar o resultado funcional após uso plasma argônio como adjuvante estendida. Métodos Cinquenta pacientes que atendiam todos os critérios inclusão foram selecionados submetidos broca alta velocidade fotocoagulação entre julho 2016 janeiro 2019. À consulta acompanhamento, avaliados...

Background: Segmental bone loss in the femur and tibia is most often due to traumatic loss, resection of septic aseptic nonunion, tumors. Reconstruction these segmental defects incurs significant economic social costs. The defect has been treated with Masquelet’s induced membrane technique transport using Ilizarov circular external fixator six-axis correction systems. Similarly, rail fixators for are an excellent viable alternative such cases. Materials Methods: This ambispective...
