The quest for new photoinitiators (PIs) capable of efficiently absorbing multiphoton, particularly three-photon, has intensified due to the multiphoton polymerization (MPP) technique. MPP enables fabrication next-generation photonic micro-...
Determining the role of defects in materials can be an important task both for fundamental understanding their influence on material properties and future applications. In this work, we studied second harmonic generation (SHG) hexagonal boron nitride (h-BN). We characterized sample by photoluminescence imaging spectroscopy, showing strong sharp emission at visible range from h-BN flakes due to single defect states. By doing imaging, found that correlates spatially with imaging....
Given the long subclinical stage of Alzheimer's disease (AD), study biomarkers is relevant both for early diagnosis and fundamental understanding pathophysiology AD. Biomarkers provided by amyloid-${\unicode[Times]{x3B2}}$ (A${\unicode[Times]{x3B2}}$) plaques have led to an increasing interest in characterizing this hallmark AD due its promising potential. In work, we characterize A${\unicode[Times]{x3B2}}$ label-free multimodal imaging: combine two-photon excitation autofluorescence (TPEA),...
We have found different Raman signatures of AB fibrils and in brain tissues from unmixed analysis, providing a detailed image amyloid plaques the brain, with potential to be used as biomarkers.
Accelerators Driven Systems (ADS) are an innovative type of nuclear system, which is useful for long-lived fission product transmutation and fuel regeneration. The ADS consist a coupling sub-critical core reactor proton beam produced by particle accelerator. These particles injected into target neutrons production spallation reactions. then used to maintain the chain in subcritical core.The aim this study investigate evolution lead cooled accelerator driven system energy high-level waste...
Among the projects of IV generation reactors available nowadays, (High Temperature Reactors) HTR, are highlighted due to their desirable characteristics and they have been studied by Instituto Nacional de Ciências e Tecnologia Reatores Inovadores/CNPq(Brazil). For this work, it evaluated neutronic behavior fuel composition during burnup using codes (Winfrith Improved Multi-Group Scheme) WIMSD5 MCNPX2.6, inserting different percentages reprocessed in core. The type "C" coming from Angra-I...
Hyperspectral Raman imaging of amyloid plaques and lipid halo in the brains mice were able to differentiate control, young aged Alzheimer's disease transgenic mouse models.
Direct laser writing (DLW) has been recognized as a unique technique for three-dimensional (3D) prototyping with resolution beyond the diffraction limit. One trend in DLW technologies is use of polymers, given their favorable mechanical properties and optical quality, rendering them promising next generation nonlinear photonic devices. However, absorptive that facilitate processes may also hinder performance polymers all-optical Furthermore, increasing ultrashort pulse lasers makes...
GB is a linking code developed at the Departamento de Engenharia Nuclear/UFMG to couple MCNP with depletion and burnup capability of ORIGEN2.1. In first version GB, described behavior during burn up only 25 isotopes. The amount isotopes be considered in simulation was increased used this paper (named GB5). It simulated 75 time steps 800kw Heat Pipe Power System model. Results showed that GB5 able generate very similar results compared MCNPX2.6.0. small difference encountered neutron flux...
