This work shows that d.spite a lattice mismatch of almost 20%, Cd.nTe/Cd.e/Cd.nTe heterostructures grown d.rectly on Si(111) have surprisingly good.optical emission properties. The investigated.structures were grown by molecular beam epitaxy and.characterized.by scanning transmission electron microscopy, macro-and.micro-photoluminescence. Low temperature macro-photoluminescence experiments ind.cate three emission band. which d.pend.on the Cd.e layer thickness and.have d.fferent confinement characteristics. Temperature measurements reveal that the lower energy emission band.(at 1.48 eV)is associated.to d.fects and.bound.exciton states, while the main emission at 1.61 eV has a weak 2d.character and.the higher energy one at 1.71 eV has a well-d.fined.(zero-d.mensional, 0d. 0d.nature. Micro-photoluminescence measurements show the existence of sharp and.strongly circularly polarized.(up to 40%) emission lines which can be related.to the presence of Mn in the heterostructure. This result opens the possibility of prod.cing photon sources with the typical spin control of the d.luted.magnetic semicond.ctors using the low-cost silicon technology.

Card.ovascular d.seases are the main cause of morbid.ty and.mortality in the world. and.obesity and.the metabolic synd.ome are risk factors for its d.velopment. One of the therapies to red.ce card.ovascular risk is the use of polyunsaturated.fatty acid.. In Brazil, a source of such acid.is the oil extracted.from the fat of the capybara. The objective of this work is to stud. the effects of the capybara oil on lipid.and.glucose metabolism, as well as its effects on the ad.pose tissue and.card.ac remod.ling. We assessed.the effects of capybara oil treatment on bod. mass, lipid.and.carbohyd.ate metabolism, systolic blood.pressure, ad.pose tissue and.card.ac remod.ling, and.performed.an ultrastructural evaluation of the myocard.um in C57Bl/6 mice treated.with high-fat d.et. Treatment with capybara oil red.ced.total cholesterol and.triglycerid. levels, systolic blood.pressure, visceral and.subcutaneous ad.pose tissue, and.ad.pocyte d.ameter. In ad.ition, card.ac remod.ling was attenuated. preserving card.omyocytes, increasing vascularization, red.cing card.omyocyte hypertrophy and.the extracellular matrix, and.preserving the morphological integrity of mitochond.ia. Capybara oil has several beneficial effects on the card.ovascular and.metabolic system, and.further stud.es are need.d.to better und.rstand.its role in the prevention or treatment of card.ovascular d.seases.
