Luminescent converters based on semiconductor quantum dots
Dr. Dulat Daurenbekov
Doctor of Philosophy PhD, Assistant Professor of the Department of Technical Physics,
Increasing the efficiency of solar cells. The «working» spectral range for solar cells based on polycrystalline silicon lies in the red and near infrared region. Most (about 70%) of ultraviolet and visible solar radiation goes to heating solar cells, so only 30% of solar radiation is used to generate electricity. To improve the efficiency of solar cells, it is necessary to convert high-energy solar radiation into red radiation. In this regard, we are investigating luminescent converters for down-conversion of the high-energy solar spectrum to the long-wavelength region, where solar cells have the best response. For effective use of the visible and ultraviolet range of solar radiation, it is proposed to use a luminescent coating based on CdSe / ZnS and CdTe quantum dots.
Green synthesis of metal oxide nanomaterials their application photocatalytic activity for the remediation of environmental pollutants
Dr. Narsi Boya
University of Hyderabad, India
The current study is synthesis of environmentally benign metal oxide nano-materials using agro-waste extract in the absence of chemical reducing agent, toxic solvents, and stabilizing agent. The sustainable synthesis of metal oxide nanomaterials provides an eco-friendly and more exciting approach in the domain of a clean environment. Besides, plant extracts to synthesise nanoparticles have been considered a more superior one of the eco-friendly methods. This paper describes the biosynthetic preparation route of three different sizes, shape, structure metal oxide materials from the agro-waste aqueous extract at 200 ℃, 500 ℃ and 800 ℃ for 3h and represents a low-cost and alternative preparation method. The synthesized metal oxide nanomaterials samples were characterised by several advanced analytical techniques such as X-ray diffraction (XRD), Fourier transform infrared (FT-IR) Spectro-photometry, ultraviolet-visible (UV–Vis) absorption spectroscopy, high-resolution electron microscope (HR-TEM) and energy dispersive X-ray (EDX) spectroscopy. Surface area and porosity size distribution were identified by nitrogen adsorption-desorption isotherms BET analysis. The photocatalytic properties of the metal oxide nanomaterials samples were studied against the methylene blue (MB) and methyl Orange (MO), as Rhodamine B (Rh-B) i.e and the degradation was evaluated with three different size nanomaterials. Photocatalytic activities were carried out under a multi-lamp (125 W Hg lamps) photoreactor. The smallest size sample exhibited the highest degradation efficiency within lesser time than the most significant size sample. Therefore, our studies suggested that the developed metal oxide materials nanomaterials could be potential, promising photocatalysts against degradation of industrial effluents.
Hydrogen embrittlement in Beta titanium alloys – A review
Dr. Julio González
Shanghai Jiaotong University, China
Beta titanium alloys are considered good candidates for applications that require moderate strength, toughness, formability, and resistance to corrosion. However, several studies have claimed their susceptibility to hydrogen embrittlement (HE) after annealing and aging heat treatments above a certain threshold. This briefing covers significant findings from the last few decades regarding the impact of hydrogen on the mechanical properties of these alloys, as well as new trends and future perspectives in this field.
Magnetization dynamics and thermoelectric effects on flexible nanostructures
Marcio Assolin Correa
Departamento de Física, Unversidade Federal o Rio Grande do Norte Natal, RN, Brasil
Magnetization dynamics and thermoelectric effects of ferromagnetic materials have been widely studied in the last years due to their potential application in power-saving electronic devices. The dynamics and thermoelectric response of ferromagnetic films are strongly dependent on the electrical and magnetic properties, as well as the deposition procedure and employed substrates. More recently, the interest in flexible electronics development has been revived the scientific community’s attention. Consequently, the investigation of the magnetization dynamics and thermoelectric effects in flexible substrates appears as an attractive field of investigation. In this work, we show our recent results in this field. To this end, films of CoFeB and CoFeAl alloys grown onto flexible substrates produced by magnetron sputtering are explored. The magnetic anisotropy configuration is modified by bending the sample, leading to a controlled stress application. This procedure enables us to manipulate the magnetization dynamics and thermoelectric responses. Moreover, we propose a theoretical approach based on the modified Stoner Wohlfarth model to describe our experimental results.
Superconductivity in Ni-Bi system: one example of applications of high-resolution electron microscopy in physics
Yutao Xing
Institute of Physics, UFF
In this talk I will give a brief introduction to the High-Resolution Electron Microscopy Laboratory (LaMAR) of Federal University of Fluminense and its applications in research of physics. One example is the superconductivity in Ni-Bi system. With detailed microstructural study of the Ni-Bi interface, we conclude that Ni and Bi reacted spontaneously during deposition and formed NiBi3 and NiBi intermetallic compounds. These two compounds are the origin of the superconductivity in Ni-Bi system.
