5. GLASS AND MATERIALS BASED ON MINERAL MELTS
Following the successful edition in , the Symposium is devoted to academic and industrial partners working on the substitution and recyclability of critical raw materials CRM in electronic, magnetic and energy harvesting devices.
Raw materials are the basic, but fundamental, elements for a wealth of current technological applications. New research and development activities are required to improve the fundamental understanding of new material solutions containing reduced or no critical content while maintaining or enhancing the performance of the materials, components and products.
The symposium provides an interdisciplinary platform to discuss about CRM alternatives from the modelling, synthesis, characterization, processing and device integration viewpoints. Bringing together researchers from academia and industry we aim at increasing the interaction among scientists, engineers, and students working on different areas of the CRM field that are too often treated separately. The symposium is organized by members of the EIP RESET commitment, and will therefore be included and publicised within the program of activities of the commitment.
Resume : Two decades after the development of the blue light-emitting diode LED , LEDs have quickly established themselves as the lighting technology of the future. The high efficiency, spectral tunability, lack of toxic compounds and a small footprint makes them far more attractive than other lighting technologies.
White LEDs are commonly based on a blue LED, combined with luminescent materials, or phosphors, which convert part of the blue light to longer wavelengths, the mixture providing white light. Six main requirements for LED phosphors are discussed and used to explain the discrepancy between the high number of compositions described in literature and the handful of actually used compounds, being almost uniquely based on rare earth ions as luminescent center .
Finally, the impact of phosphor geometries on phosphor use, including remote phosphor applications, are discussed. They were chosen because of their efficient emission in the UV and deep blue spectral range with quantum efficiency up to 0. The influence of steric hindrance of the chromophores on the electroluminescence EL properties has been shown. With passing from Bzx to BBzx, a shift of the emission from green to deep blue was observed.
The studies show deep blue emission at nm assigned to BBzx and the appearance of a blue emission band at nm originating from ETL. These optical features specific to BBzx based devices are attributed to the modification of electronic states induced by the non-planar conformation of BBzx molecules in thin solid-films. The color saturation of BBzx based devices was attributed to its twisted molecular structure leading to the reduction of the vibration splitting, and hence narrow EL spectra in the solid state.
The results suggest that bis-benzoxazole molecules may be useful as an efficient color saturation deep-blue emitter in OLED. Resume : Cesium lead halide perovskite light emitting materials have attracted attention by these high color purity and stability. The narrow full width at half maximum FWHM and low cost of raw materials makes halide perovskite materials highly potential advanced materials for applications in light emitting diodes.
Furthermore, low energy synthesis process and possibility of output product to be either solution or powder, adds to widespread applications. Extra-ordinary optical properties make halide perovskite favored materials for next generation lighting materials.
In this study, CsPb Br0. Fabricated cesium lead halide perovskite films showed outstanding characteristics FWHM of 32nm and high luminous efficacy of We propose the CsPb Br0.
Resume : Use of Graphene Gr in many optical and electronic devices is continuously growing due to its large transparency and high charge mobility. These features push for substitution of single layer Gr in transparent conductive layers and in the channel between source and drain of microelectronic devices. To this aim it is mandatory to determine the mechanical and electrical changes of Gr during its use as, for example, due to heating or reaction with atmosphere gases.
Furthermore, the possibility to tune the charge carrier content and the Fermi level by opportune thermal treatments is foreseen for device realization. The investigation is carried out by a time resolved procedure to highlight how the kinetics aspects affect the involved processes. It is found that doping is characterized by double rate kinetics as well as the de-doping effect induced by exposure to ambient atmosphere.
These results are interpreted on the basis of two physical and chemical competing processes: molecular adsorption and red-ox reaction.
A prominent role of gas is evidenced showing the largest effectiveness of doping by O2 and de-doping by H2O in gas phase as contrasted to liquid. Finally, the strain effect is dominant in inert atmosphere and strongly sensitive to the kinetics of treatment. Resume : The transparent and conductive AZO films were successfully prepared with the good electrical and optical properties comparable to commercial ITO substrates.
It was found that the obtained metal oxide film not only contributed to be conductive film but also to the vertically alignment of ZnO nanorods during reducing annealing process, resulting in the high transmittance of the ZnO based photoanodes in DSSC. The good vertical alignment of the ZnO nanorods was significantly dependent on the crystallinity of AZO film. The pure anatase structured TiO2 thin films were successfully coated on ZnO nanorods with very good uniformity.
Resume : Developing transparent conductors that can utilize a portion of the UV range of the sunlight to increase solar cell efficiency requires bandgap engineering by varying the process parameters as well as type and concentration of dopants in the host materials. To this end, ZnO is a desired material because of its wide direct band gap Eg of 3.
Whereas Mg is found to increase the overall transmittance of these films, Al addition is found to increase both the carrier concentration and carrier mobility, with the best values of the electrical properties being obtained when only Al is added to ZnO. Resume : In order to know the threshold quantity of the zinc interstitials that contributes in an increase in carrier concentration in the Al-doped ZnO AZO films and their effect on the overall microstructure and optoelectronic properties of these films, in this work, Zn-rich- AZO films are fabricated by adding excess zinc from a zinc metallic target during their deposition in RF magnetron sputtering and are then investigated using a wide range of experimental techniques.
To understand fundamentally the role of zinc atoms in creating the electronic defect states and thereby tuning the overall microstructure and optoelectronic properties of these films, we conducted similar sets of experiments also with the ZnO films.
Additionally, aluminum is seen to enhance the creation of these electronic defect states in these films, thereby contributing more to the overall carrier concentration of these films. Whereas, optical band gap for the ZnO films is found to increase with increasing carrier concentration because of the B-M shift, these decrease for the AZO films due to the band gap narrowing effect caused by excess carrier concentration.
Resume : A detailed understanding of the individual layers i. Often a slight variation in the process condition varies the microstructure and thereby induced optoelectronic properties of these layers, hence significantly affecting the device performance.
A detailed microstructural and optoelectronic characterization of all these films are then carried out by using a wide range of experimental tools. However, electrical resistivity decreased for the bilayers deposited in process II as compared to process I, due to an increase in carrier concentration because of enhancement in the shallow donor level defects like, Zn interstitial, extended Zn interstitials and single charged oxygen vacancies and carrier mobility due to improvement in the crystallite sizes, suggesting its enhanced suitability in CIGS thin film solar cells.
Resume : Lithium-sulfur Li-S batteries are regarded as potential high-energy storage devices due to their outstanding energy density. However, the low electrical conductivity of sulfur, dissolution of the active material, and sluggish reaction kinetics cause poor cycle stability and rate performance. A variety of approaches have been attempted to resolve the above issues and achieve enhanced electrochemical performance.
However, inexpensive multifunctional host materials which can accommodate large quantities of sulfur and exhibit high electrode density are not widely available, which hinders the commercialization of Li-S batteries.
Herein, mesoporous carbon microspheres with ultrahigh pore volume are synthesized, followed by the incorporation of Fe-N-C molecular catalysts into the mesopores, which can act as sulfur hosts. Furthermore, the uniform distribution of Fe-N-C only 0. The resulting electrode with 5.
Resume : There is need to develop high-performance large-scale batteries for the intermittent energy sources. However, high-performance electrode materials are required for the realization of SIBs. Herein, a nanocomposite based on SnF2 and acetylene black is proposed as a high-performance anode material for SIBs. The SnF2 C electrode delivers a high reversible capacity of mAh g-1 which is higher than the specific capacity of mAh g-1 of the micron-sized bare SnF2 electrode.
The in-situ XRD results show the existence of a solid solution of two or more compositions during cycling. Resume : Electrocaloric EC cooling is a promising future technology of large area refrigeration. The relative efficiency of a refrigerant is defined as the ratio of the coefficient of performance COP - the useful heating or cooling provided divided by the work required to the COP of an ideal Carnot cycle.
An extrapolation of available experimental data to higher electric fields predicts for BZT EC temperature changes of up to K suitable for commercial application. Resume : There are numerous high temperature stainless steels, which usually exhibit high creep strength, good resistance to isothermal, good resistance to cyclic oxidation, good resistance to combustion gases, good structural stability at high temperatures.
Among the material properties, relatively low strength is the major issue of high temperature stainless steel, especially austenite phase stainless steel. However, the mechanical response of present high temperature stainless steel, MA as example, should be further increased to meet the environmental requirement for the applications of waste heat recycling or high efficiency engine. In this study, the idea of precipitation hardening similar to duplex stainless steel is introduced to strengthen MA.
The Cr content is designed to raise in order to precipitate second phase at the grain boundary as the obstacle of dislocation propagation during the deformation at high temperature. The samples of the as-casted MA and MA with more Cr content are conducted tensile test both at room temperature and oC. In the preliminary research results, both the yield stress and tensile strength at high temperature are increased significantly. And the relationship between the mechanical response and microstructure would be examined carefully and discussed in detail.
Resume : In recent years Ni-based nanostructures have attracted great attention for electrochemical energy storage applications.
In this work, we present a novel Ni nanostructure with a very high surface over volume ratio and with promising features in terms of specific capacitance and stability, if compared with the amount of critical raw material used Ni. Scanning electron microscopy SEM reveals that the Ni nanostructure, grown by chemical bath deposition CBD followed by a reducing annealing, consists of an ensemble of interconnected Ni nanoparticles nm in size. This work offers a new strategy to enhance the energy storage performances of conventional Ni OH 2-based electrodes, by reducing the amount of used Ni.
Resume : For the electronics, optical and solar cell applications, a transparent conductive thin film is very important material. So for, polycrystalline ITO material is commonly used for their applications because of low resistivity at low processing temperature by using the physical vapor process. Tin oxide is a promising material for next electronic devices because it offers good properties, such as high conductivity, transparency, and chemical stability.
In addition, it is also an abundantly available natural resource. However, in most cases, the processes for Tin oxide growth require both vacuum and high temperature, making device production expensive. The effects of wavelength, shot number and Sb-doping content on the electrical properties such as resistivity, carrier concentration and mobility were investigated. By using the photo process, SnO2 film was formed at room temperature.
In addition, Sb content can be reduced compared with thermal process. The difference in the optimum Sb doping concentration and resistivity between excimer laser assisted MOD process and thermal MOD process were discussed. Resume : Considering the recent global interest in reducing energy consumption, SiC power electronics technology is now ready to enable the step to the next plateau for efficiency standards.
In most case, SiC power modules are designed to work at operating temperatures around oC. Therefore, comical available electronic components such as resistor cannot use for the SiC modules because the electrode and resistor materials are deterioration in the temperature. In addition, we found that the trimming part is not good for the heat cycling properties oC.
Moreover, present resistor is made of the mixture of RuO2 and glass. So, development of the high heat resistant resistor without using the rare metal and glass composite would be desired for preventing the Resource depletion.
In order to protect the environment and critical resources of the next generation society, it is necessary to construct an innovative alternative and circulation cycle of the main materials and components of green devices.
Therefore, a development high heat resistant new electronic component such as resistor is necessary. Bi2Sr2CaCu2Oy is candidate materials for new high heat resistant resistor. Detailed results will be presented in the conference. Not at all, we use the Cl-containing agents more environmentally friendly than F-containing agents.
These synthesis are not reported in the literature. In the synthesis process, we control the temperature and concentration of TiCl4 to find the best condition TiO2. Finally, the best condition product VT length and thickness about nm and nm.

The invention relates to a flexible article suitable for producing substrates of flexible devices and the production process thereof. Flexibility is the trend of development of electronic devices. The substrate of a flexible device can be glass, metal foil and polymer. Polymer has flexibility and high surface smooth, but its temperature stability is low, not meeting the processing requirements of flexible devices, such as displays, lighting equipment, solar cells and so on. Glass also has high surface smooth, but it is difficult to render glass flexible. Normally, the thinner the glass is, the more flexible it is.

The risk of the increased levels of radioactive radiations determines a special attitude to the atomic energy and radwastes RW and demands the acceptance of cardinal and operative measures on their isolation from people. As regards the glass matrixes, they allow to reduce the volume of the conditioned waste products and to improve sharply physical and chemical properties of the matrix, but at the same time due to an amorphous structure have a number of disadvantages such as: high fragility, presence of numerous structural defects, low homogeneity and density and also rather low radiation resistance. During the last stage the optimal regimes of the extraction of radioactive nuclides by zeolites have been specified on the pilot machine. Thus, in the static and dynamic conditions the significant reduction of LRW volumes up to times with their transformation into a hard phase has been achieved. At the same time, the reduction of LRW volumes was considered by the participants of the above mentioned project as a temporary measure till the development of the technology of sitallization of sorbents with high concentration of radioactive nuclides and slurries got from the Deep Evaporation Machine. This direction of works, on which the prediscovery had been carried out, demands much more time and new financial support. In the suggested project the high-competent personnel will participate. Particularly the participants of the project made the following steps:.
