Most of the advanced materials, Metallurgical materials, Semiconductors, Ceramic materials, and Plastics have been used in a wide area of applications like structural, mechanical, chemical, electrical, electronic, optical, photonic, biological, medical, etc. Most of them, except for bio-polymers & bio-minerals, have never been produced via biological systems. Thus they have generally been fabricated artificially and/or industrially by so-called high-technology, where harsh conditions & high energy species like high temperature, high pressure, vacuum, molecule, atom, ion, plasma, etc. have been used for their fabrications, thus consumed a huge amount of resources and energies then exhausted huge amounts of wastes: materials, heats, and entropy. To save this tragedy, we must consider “Cascade use of Heats” and “Low energy Production of advanced nano-materials via water-based processings.” Bio-inspired process, which means that “Learn from Bio-systems then Exceed them”. We have challenged to fabricate those advanced inorganic materials with the desired shape/size/location, etc. directly in low energetic routes using aqueous solutions since 1989 when we found a method to fabricate BaTiO3 film on Ti substrate in a Ba(OH)2 solution by Hydrothermal Electrochemical[HEC] method at low temperatures of 60-200 C. We proposed in 1995 an innovative concept and technology, “Soft Processing” or “Soft Solution Processing,” which aims low energetic (=environmentally friendly) fabrication of shaped, sized, located, and oriented inorganic materials in/from solutions1,2). It can be regarded as green processing or eco-processing. When we have activated/stimulated interfacial reactions locally and/or moved the reaction point dynamically, we can get patterned ceramic films directly in solution without any firing, masking, nor etching—direct Patterning of CdS, PbS, and CaWO4 on papers by Ink-Jet Reaction method. Furthermore, we have succeeded in fabricating BaTiO3 patterns on Ti by a laser beam scanning3) and carbon patterns on Si by plasma using a needle electrode scanning directly in solutions. Successes in TiO2 and CeO2 patterns by Ink-Jet Deposition, where nano-particles are nucleated and grown successively on the surface of the substrate, thus become dense even below 300 oC will be presented. Nano-structured films will also be talked. .A recent novel subject, Soft Processing for various nano-carbons including graphene and functionalized graphene will be introduced. Where we have succeeded to prepare functionalized Graphene Ink via successive processes under ambient temperature and pressure conditions.","PeriodicalId":90703,"journal":{"name":"Proceedings.

In this context, solid-state devices based on fuel cells have gained significant interest owing to their variable fuel usage, better performance evaluation, and tailored long-term endurance. In such an aspect, the primary role is employed by the materials viz. electrode and electrolyte irrespective of the operating temperature. \u0000An account will be provided by the speaker on the correlation among tailoring the properties of the electrode through functionalization during synthesis and performance evaluation of the solid-state devices. Research work on functional anode materials applicable to high temperature fuel cells will be discussed. Functionalization of Ni-yttria stabilized zirconia composite through particulate deposition technique enables the formation of unique Ni@SZ microstructure, thereby resulting in a high current density of 3.7 A.cm-2 at 800oC for coupon cell(16-23 mm) with high endurance for 2000 hrs. Penetration depth analysis of such cermet has been carried out successfully as a function of Ni content. The effectivity of such anodes will also be discussed with multiple fuels. For low-temperature applications, polymer-based electrolytes are employed. Functional poly (ethylene oxide) based electrolyte with optimized compositions are reported to significantly enhance the performance with even better long term tenability.","PeriodicalId":90703,"journal":{"name":"Proceedings.

These hexavalent fumes are carcinogenic and cause respiratory problems to the welders and personnel in the vicinity of welding. In the present research work, novel Chromium free Nickel-based filler material of % wt composition 41 Ni, 8 Co, 16 Fe, 14Mo, 7 Mn, 8 Cu, 3 Nb, 1 Ti, 1 Si, 1 Al is developed and its weldability with stainless steel is studied. The microstructure and chemical composition of different metallurgical phases in the filler material and weld joints are studied using different microscopy tools and X-Ray Diffraction, respectively. The ultimate tensile strength of the filler material and weld joint welded by developed filler material is found to be 536MPa and 487 MPa, respectively. The average hardness and toughness of the filler material and welded joint are 190VHN &110J and 209VHN & 89 VHN, respectively. Results of Potentio-dynamic polarization and Inter Granular corrosion cracking (IGCC) of the weld joint has shown the corrosion rate of 1.575e-004 mils/year and 354.56 miles/year, respectively. Mechanical properties and corrosion rate of weldments welded by novel filler material are compared with that of conventional filler material. Design of experiments(DOE) using Taguchi L9 array is formulated to understand the influence of Welding current, root gap, and gas flow rate on output parameters such as Tensile Strength, Toughness, and corrosion resistance of weldment. DOE using RSM has shown maximum Tensile strength of 487Mpa, maximum Hardness of 209 VHN, and a minimum corrosion rate of 1.575e-004 mils/year has obtained with an optimum current value of 130A, 11.79 litres/min gas flow rate, and 2.33mm root gap.","PeriodicalId":90703,"journal":{"name":"Proceedings.

While there is a wide choice of commercial 3D printers, few reach nanometer resolution and feature size. The difficulties arise from special high precision required for materials delivery and registry among layers in the printing process. Scanning probe microscopy (SPM) has been widely used by the research and development community to visualize specimens with unprecedented resolution: reaching nanometer levels routinely and atomic and molecular levels on occasion. , The localization of SPM at atomic and molecular scale, has been harnessed to control interactions of molecules toward 2D and 3D nanolithography.

Among the different approaches adopted to overcome this problem, mechanically and electrically rechargeable as well as refuelable systems have been deeply studied for automotive and stationary applications. In a refuelable Zn-air battery, the alkaline aqueous electrolyte is pumped into the cell, either carrying Zn electroactive fuel or flowing through a packed bed of Zn particles. In a previous paper, we adopted a mechanically refuelable tapered-end flow Zn-air fuel cell with Zn micro-spheres, and we studied the effect of electrolyte aging on the behavior of the Zn anode during battery discharge. The results have shown that the cell potential decrease in the battery discharge curve is mainly due to the anodic overpotential increase, as evidenced by means of EIS (Electrochemical Impedance Spectroscopy) measurements. Given that this effect can be attributed to the physicochemical modifications induced by the Zn passivation occurring at higher zincates concentration, the performance of the battery system can be notably improved by a relevant regeneration of spent alkaline zincate bath.\u0000Here, we propose a novel method to recover zinc from alkaline zincate baths by using aluminum electrodes. Aluminum metal and zincate ions give place to a single-displacement reaction producing a layer of zinc on the Al surface. The deposits of zinc metal on aluminum foils have been studied by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and the electrochemical process has been followed by open circuit measurements in order to put the basis of future developments.","PeriodicalId":90703,"journal":{"name":"Proceedings.

These compounds have been recently investigated with renewed interest, appearing as a novel class of materials for hydrogen storage, thanks to their proven capability to uptake reversibly high amounts of hydrogen via a complex chemisorption mechanism. In this presentation, after a short summary on the hydrogen storage topic, the synthesis, the structural investigation, and the hydrogen storage properties of Li, Na, and mixed Li-Na clusters intercalated fullerides belonging to the families NaxLi12-xC60 (0 ≤ x ≤ 12) and NaxLi6-xC60 (0 ≤ x ≤ 6) will be presented. By manometric and thermal analyses, it has been proved that C60 covalently binds up to 5.5 wt% H2 at moderate temperature and pressure, thanks to the catalytic effect of the intercalated alkali clusters. Moreover, the destabilizing effect of Na in the co-intercalated NaxLi6-xC60 compounds leads to an improvement of the hydrogen-sorption kinetics by about 70%, linked to a decrease in the desorption enthalpy from 62 to 44 kJ/mol H2. The addition of Pt and Pd nanoparticles to Li fullerides increases up to 5.9 wt% H2 the absorption performances and of about 35 % the absorption rate. The ammonia storage properties of Li6C60 have also been investigated, resulting in quite appealing. Being the price of C60 quite high, cheaper C based materials are under examination. Porous biochar from agricultural waste is giving interesting results as electrode materials for high-performance supercapacitors.","PeriodicalId":90703,"journal":{"name":"Proceedings.

The aim of this study is to analyze the thermo-mechanical properties of the developed fibers in addition to cell adhesion and proliferation analysis. The HA is synthesized from sundried raw fish scales of carpa family. The fish scales are calcinated at 800°C in a box furnace and are bead milled for one hour in a nano agitator bead mill for particle size reduction. Thus obtained nanoparticles are characterized using XRD, SEM, and TEM for particle size reduction, crystallinity, and structure. The PCL solution formed by dissolving 16 wt% of PCL in chloroform is magnetically stirred for 3 hrs at 170 rpm. The HA nanoparticles were infused in this solution by 1, 2, and 3 wt% and is stirred in a think mixer under vacuum for 7 mins for uniform dispersion of nanoparticles in the solution. The solution mixture is injected into the spinneret of force spinning apparatus. The PCL/HA fibers were collected at rotational aped 7000 rpm with a spin time of 10mins. The thermo-mechanical properties of the fibers were analyzed using tensile test, DSC, and DMA analyses. The biological assessment of the fibers is done using in vitro cell studies of the scaffolds that were cut from the fibers. These scaffolds can be further used for various biomedical applications such as sutures and controlled wound healing.","PeriodicalId":90703,"journal":{"name":"Proceedings.
