The defects in the host lattice play a major role in tuning the surface roughness, optical band gap and the room temperature ferromagnetism (RTFM) of ZnO thin films. Herein, we report a novel approach to tailor the band gap and RTFM of a ZnO nanostructure by varying the angle of implantation of 60 keV N ions keeping the ion fluence of 1 × 1016 ions per cm2 and the beam size of 3 mm constant. The implantation was performed by changing the thin films'' orientations at 30°, 60° and 90° with respect to the incident beams. Remarkably, an enhancement of ∼6 times in RTFM, tuning in band gap from 3.27 to 3.21 eV and ∼60% reduction in surface roughness were noticed when the ion implantation was done at 60° to the normal. This novel technique may be suitable for tuning the physical properties of nanostructures for their application in the spintronics, semiconductor and solar cell industries.The defects in the host lattice play a major role in tuning the surface roughness, optical band gap and the room temperature ferromagnetism of ZnO thin films. 相似文献

BackgroundRCTs that have shown improvement in coefficient of fat absorption with pancreatic enzyme replacement therapy (PERT) have seldom evaluated the impact on overall nutritional status.ObjectiveIn this study we evaluated factors responsible for persistence of malnutrition after PERT.MethodsIn this cross-sectional observational study, patients were enrolled based on predefined enrolment criteria. Patients were divided into those taking PERT regularly (Group A), irregularly (Group B) and not taking (Group C) for at least 3 months. Comprehensive evaluation of anthropometric measurements, nutritional assessment and dietary intake was performed. Malnutrition was measured using the Subjective Global Assessment (SGA) tool. Relationship between PERT status, dietary intake and nutritional status were evaluated using standard statistical methods. Logistic regression was performed to identify factors associated with persistence of malnutrition after PERT.Results377 patients with CP and 50 controls were included. 95 (25.2%) patients with CP were in Group A, 106 (28.1%) in Group B and 176 (46.7%) in Group C. 130 (34.5%) patients were malnourished, of which 76 (58.5%) were continuing PERT. There were no differences in clinical and biochemical nutritional markers between Groups A, B, and C. Calorie deficit and daily intake of calorie, protein, carbohydrates and fats were not different between those with and without PERT, but was significantly less in those with malnutrition. Logistic regression demonstrated inadequate dietary intake as independent risk factor for persistence of malnutrition.ConclusionEven though PERT is effective in PEI, comprehensive nutritional assessment, personalized nutritional counselling and therapy along with PERT is mandatory. 相似文献
