Raman spectroscopy and infrared (IR) are both techniques that allow for the investigation of vibrating chemical particles. These provide information not only about particles through identification functional groups spectral analysis so-called "fingerprints", these methods qualitative quantitative analyses substances in sample. Both frequently being used biology medicine diagnosing illnesses monitoring therapy. The type breast cancer found woman is often a malignant tumor, causing 1.38...
TiO2/CuO and TiO2/Cu2O solar cells are promising devices for photovoltaic applications. The power conversion efficiency of these cells, however, remains low. We used the SCAPS-1D program to perform simulations n-TiO2/p-Cu2O n-TiO2/p-CuO thin-film cells. short circuit current were 13.3 mA cm−2, 28.4 cm−2 13.7% 22.4%, respectively, Furthermore, we evaluated some specific parameters heterostructure, such as influence temperature, interface state density, metal work function, electron hole...
Copper oxide-titanium dioxide (TiO 2) p–n junctions are promising materials for photovoltaic devices and may reduce production costs due to their low cost inexpensive methods compared with silicon solar cells. The present review compares cells made copper oxides combined TiO 2–TiO 2/Cu 2O 2/CuO heterojunctions, “cascade heterojunction systems.” First, we describe the main properties of titanium (iv) 2), cuprous oxide (Cu 2O), cupric (CuO), potential applications. Next, explain concept 2...
In the presented work, Cu2O/TiO2 and CuO/TiO2 heterojunction solar cells have been analyzed by help of Solar Cell Capacitance Simulator (SCAPS). The effects various layer parameters like thickness defect density on cell performance studied in details. Numerical analysis showed how absorber (CuO, Cu2O) buffer (TiO2) layers influence short-circuit current (Jsc) efficiency (η) cells. Optimized structures a potential ∼9 ∼23%, respectively, under AM1.5G spectrum. Additionally, external quantum...
The aim of this study was to optimise the experimental protocol and data analysis for in-vivo breast cancer x-ray imaging. Results are presented experiment at SYRMEP beamline Elettra Synchrotron using propagation-based phase-contrast mammographic tomography method, which incorporates not only absorption, but also phase information. In images tissue samples, a size corresponding full human breast, with radiologically acceptable doses were obtained, degree improvement image quality (from...
Pulmonary hypertension secondary to bronchopulmonary dysplasia (BPD-PH) represents a major complication of BPD in extremely preterm infants for which there are currently no safe and effective interventions. The abundance interleukin-1 (IL-1) is strongly correlated with the severity long-term outcome we have previously shown that IL-1 receptor antagonist (IL-1Ra) protects against murine BPD; therefore, hypothesized IL-1Ra may also be BPD-PH. We employed daily injections model BPD/BPD-PH was...
Abstract Triple-negative breast cancer is the most aggressive subtype with limited treatment options and a poor prognosis. Approximately 70% of triple-negative patients fail to achieve pathologic complete response (pCR) after chemotherapy due lack targeted therapies for this subtype. We report here development focal-plane-array Fourier transform infrared (FPA-FTIR) microspectroscopic technique combined principal component analysis (PCA) monitoring effects in patients. The PCA results...
Fourier transform-infrared (FT-IR) spectroscopy has gained considerable attention among the forensic scientists because it shows high sensitivity and selectivity offers near real time detection of analyzed samples. However, amount obtained information due to complexity measured spectra forces use additional data processing. Application multivariate statistical techniques for analysis FT-IR seems be necessary in order enable feature extraction, proper evaluation, identification spectra. In...
Histopathological analysis is the current gold standard in breast cancer diagnosis and management, however, as imaging technology improves, amount of potential diagnostic information that may be demonstrable radiologically should also increase. We aimed to evaluate clinical usefulness 3-D phase-contrast micro-computed tomography (micro-CT) at high spatial resolutions an adjunct conventional histological microscopy. Ten tissue specimens, 2 mm diameter, were scanned SYRMEP beamline Elettra...

Propagation-based phase-contrast computed tomography (PB-CT) is a method for three-dimensional x-ray imaging that utilizes refraction, as well absorption, of x rays in the tissues to increase signal-to-noise ratio (SNR) resultant images, comparison with equivalent conventional absorption-only (CT). Importantly, higher SNR achieved without sacrificing spatial resolution or increasing radiation dose delivered imaged tissues. The present work has been carried out context current development...
The oxidation state of intracellular chromium has been determined directly in mammalian lung cells exposed to mutagenic and carcinogenic compounds. Microprobe X-ray absorption spectroscopy (XAS) experiments on single V79 Chinese hamster showed that Cr(VI) Cr(V) complexes were reduced completely (>90%) Cr(III) within 4 h exposure the cells. This result provides direct evidence for hypothesis these genotoxic oxidants react rapidly with reductants.
Nanofluids (suspensions of nanoparticles in liquids) have been studied very intensively because they may find many applications fields including science, industry and medicine.
