Title: Proposition of new cold fusion reactor based on the mechanism with the flat wafer with nano structure and with the electrode to control the surface potential of metals
Biography:
Noriyuki Kodama has her expertise in nuclear physics at Tokyo Institute of Technology, has the vast experience of semiconductor process development.
Abstract:
propose the new cold fusion reactor and heat element in fig.2 based on the cold fusion mechanism shown in fig.1.
I summarize this theory in fig1. D is absorbed in metal in D2O and D enters in the surface T site after the sufficiently high D/Pd ratio, and the T site is expanded by the larger D- and adjacent T site size is smaller due to the compress by the expanded T site, so it has D+. Under this condition, the coulomb attractive force moves D+ to D-. Here we must note that surface free electron can shield the coulomb attractive force and so, to control the fusion, it must be depleted from surface of metal otherwise higher temperature is needed to trigger fusion. Fig.2 shows the flat electrode above metal to control the surface potential of metal

Abstract:
Advanced zirconium compounds show superior properties such as high refractory characteristics, abrasion resistance, corrosion resistance, fracture toughness and hardness. These products are useful candidates specifically for high temperature applications. The production is a challenge because of high temperature and/or pressure requirements to give enough densification for applications while most of them depends on different compositions. For example, ZrB2 known for its high refractory properties like good thermal shock resistance, chemical stability to liquid metals, high oxidation resistance and high melting point but requires sintering aid to lower porosity. ZrC has high abrasion resistance and similar thermal properties like ZrB2, but its low resistance to oxidation prevents some features
Wilfried Wunderlicha
Department of Material Science, Faculty of Engineering, Tokai University, JapanTitle: Active role of C₃N₄, and CQD for photocatalytic water purification, an overview
Biography:
Wilfried Wunderlich has completed his PhD in 1987 from Max-Planck Institute for Metal Research, Stuttgart and University of Stuttgart (Germany). He is full professor for material science at Tokai University since 2006. He has published more than 140 papers in reputed journals and is serving as an experienced referee for several journals
Abstract:
Photocatalytic materials used for water purification have improved over the last decades, as their important parameters for performance, such as nanometer size, high absorption factor, slow recombination rate, high carrier concentration, p/n- junction and high carrier mobility were optimized. Carbon Quantum dots (GQD) and graphitic Carbon nitrites (g-C₃N₄) [1] are used in combination with metallic or semi- conducting nanoparticles such as Ag, Pd, TiO₂ [2], ZnO.

Department of Pharmaceutics, RBVRR Women’s College of Pharmacy, Barkatpura, Hyderabad, Telangana, IndiaTitle: Novel Approaches for Transdermal Drug Delivery of Curcumin
Biography:
Dr. A. Krishna Sailaja is currently working as Associate Professor and Head of the Department in RBVRR Women’s college of pharmacy, Osmania University, Hyderabad. She has published 130 research papers in various National and International journals. She delivered more than 25 talks on novel drug delivery systems. Published 5 books and filed 4 patents.
Abstract:
Aim:-Transdermal drug delivery system has become a proven technology that offer significant clinical benefit over the dosage forms. Drugs with very short half-life, narrow therapeutic window, and poor bioavailability-transdermal drug system are convenient. Skin serves as site of drug application for local as well as systemic effects. This works provides the valuable information regarding the transdermal drug delivery system and highlights the detailed role of physical penetration and recent advance techniques such as iontophoresis, sonophoresis, microneedles, electroporation, ethosomes and transferosomes. Formulation of curcumin loaded ethosomal formulation by hot method was discussed in detail.
Materials and Methodology: For the preparation of curcumin loaded ethosomes hot method was adopted. Nine different formulations were prepared by varying the drug to lipid ratio (E1, E2, E3, E4, E5, E6), ethanol concentration (E7, E8, E9). DMSO was used as solubilising agent and soya lecithin as lipid, ethanol, as solvent, propylene glycol as permeation enhancer.The prepared formulations are evaluated for their particle size, entrapment efficiency, drug content, product yield, zeta potential drug release studies,permeability studies, SEM and mean vesicle size.
Results and discussion: Nine formulations of ethosomes were prepared by varying the drug :soyalecithin concentration and ethanol concentration. Out of the nine formulations the E5 formulation of drug : soyalecithin 1:5 ratio was found to be the best formulation with drug content of 98.1%, entrapment efficiency of 87.6%, mean particle diameter of 189.6nm, zeta potential value of -26.8mV. In vitro drug release data showed 89.3% of drug release sustained up to 10hrs and followed zero order kinetics with non fickian diffusion mechanism.Invivo anti inflammatory studies has shown percentage inhibition in paw volume of 47% with respect to control.
Conclusion:. Ethosomes has lesser particle size and good stability. Ethosomal formulation was developed for curcumin.

Abstract:
In the Recent Building Environment Thousands of Structures are Formed from Concrete Materials that is Considered to be A Hypothesis Standard Type in Which the Current Provided Aspect of Concrete Technology is Providing or Using what it’s Called Freeze Thaw Environment, Concrete in Cold Weather for Increasing or Decreasing the W/C Ratio which are Provided for Increasing or Decreasing of the Grade of Concrete, that is Observed to be as An Elastic Pattern, However the Current Concrete Material is Weak in Tension & Strong in Compression & to Equalize the Current we Provide Steel Rebar of Different Types in order to Enhance the strength of the Structural Component, However the Concrete is Affected by the Surrounding Environment to be As A Component for Different Bodies & Environments that are Found, However the Cold Environment Casting of Concrete is Governed by the W/C Ratio that the Air Entrained Bubbles should be Increased in order to Let the Freezing Thaw of Concrete Expands Within it Exactly Similar to the Expansion Joint Concept Idea, While it is the Opposite for Hot Weather Concreting, In Which Material Such as Flyash,Plastisizers & Retarders/Condensers can be Found within the Aspect of Reducing the Current Setting Time for Concrete to take Place within the Cold formed Environment, In other Hot & Cold Weather Climate Polymers are Used for Reducing the Cracking of A Structural Components & Increasing the Strength of the Concrete that is Found to be As An Imperial Material that is Used, Materials Like Fairface Sadamco,Fosroc & Henkel, Mortar Putty & Other Types of Materials Are Used for Either Increasing the Strength of Concrete or Reducing the Shrinkage Cracks that Occurs in A Structural Component.
