Determination of Hydrogen Concentration in Coated and Uncoated Steel Determination of Hydrogen Concentration in Coated and Uncoated Steel Новинка

Determination of Hydrogen Concentration in Coated and Uncoated Steel

This work was performed to quantify the total and diffusible hydrogen in metallic materials for providing information based on the susceptibility towards embrittlement. The total hydrogen determined did not exhibit enough information based on embrittlement. Hence diffusible hydrogen was measured to identify hydrogen desorption rates, desorption temperatures and activation energies in traps of differently prepared samples.This work showed the promising way to evaluate the total and diffusible hydrogen contents in metallic materials by setting up proper sample preparation methods, investigating better ways of sample storage, determining conditions that lead to absorption and desorption of hydrogen. The influence of the microstructure alloys and trapping tendencies of hydrogen were also characterised.

Water in the future can be produced by bacterial enzymes

Hydrogen peroxide is very difficult to produce in the industries, due to instability characteristics thus why we can not use the hydrogen peroxide produced in the nature. WBCs is simplest example for that,I used these characteristics with the help of bacteria S. aureus to produce water and free oxygen particles after degraded of hydrogen peroxide, which means we found a simple creature that produces the oxide without any cost which can be used in the future.

Cu-based oxide photocathodes for photoelectrochemical water splitting

The actualization of a hydrogen economy requires cost-effective and environmentally benign solutions to hydrogen production. Chemical energy in the form of hydrogen can be stored and converted into electricity at whatever time is needed. Photoelectrochemical (PEC) water splitting is a carbon-neutral process which converts solar energy into chemical energy (hydrogen) using a light-absorbing semiconducting material to generate the necessary photovoltage to split water into hydrogen and oxygen. So far, record efficiencies in solar-to-hydrogen conversion have been achieved using p-type semiconductors, but only with very expensive materials. However, the spread of this technology relies on the development of semiconductor electrodes made of cheap and abundant elements that are stable in water for a reasonable long time. The semiconductors investigated in this dissertation are cost-effective cuprous oxide electrodes having p-type conductivity, which is ideal for photocathode application. A record efficiency could be achieved by atomically depositing layers of water-stable oxides atop of cuprous oxide, which is otherwise intrinsically unstable in water under irradiation.
Passive and Active Sample Selection and Variance Discriminant Analysis Passive and Active Sample Selection and Variance Discriminant Analysis Новинка

Passive and Active Sample Selection and Variance Discriminant Analysis

Among the many existing categories of face de- tection algorithms, the sample-based method is one of the most widely-used approaches. The essence of the sample-based method is to solve a two-class classification problem of face versus non-face. Many classification algorithms such as the Naive Bayesian, Neural Network and Support Vector Machines (SVM) have been used for this purpose. This thesis showcases a research study into face detection technologies. It has two main parts. Firstly, in the sample preparation section, new passive sample selection and active sample generation algorithms are proposed to assist existing sample-based algorithms in solving the problem of face detection. Secondly, in the classification section, a new Bayesian-based classification method is proposed for face detection.

Transition Metal Nanocluster Catalysts and Chemical Hydrogen Storage Transition Metal Nanocluster Catalysts and Chemical Hydrogen Storage Новинка

Transition Metal Nanocluster Catalysts and Chemical Hydrogen Storage

The storage of hydrogen is still a major hurdle in front of the hydrogen economy. One conceptual solution is the generation of hydrogen from chemical compounds having high gravimetric and volumetric hydrogen storage capacity such as boron-nitrogen compounds. Recently, sodium borohydride and ammonia borane are considered to be the most promising ones among all other chemical hydrogen storage materials owing to their remarkable gravimetric hydrogen contents and stability in the solid state. The hydrogen stored in NaBH4 and H3NBH3 can be release via hydrolysis route. However, a suitable catalyst is required to generate hydrogen from their hydrolysis at desired rate. An efficient way of increasing catalytic activity of a heterogeneous catalyst is the use of transition metal nanoclusters (NCs) which are more active catalysts than the respective bulk metal owing to their high surface-to-volume ratio. Via this research work, we present our detailed study on the synthesis and characterization of water soluble polymer stabilized nickel(0), cobalt(0) and ruthenium(0) NCs as catalyst in hydrogen generation from the hydrolysis of NaBH4 and H3NBH3.

Towards efficient hydrogen production via water splitting

The necessity to reduce green house gas emission and growing difficulties in fossil fuel recovery raise great challenges for the scientific community to develop efficient, low cost alternative energy sources. Hydrogen is sought by many as a way to store and transport energy produced from renewable sources. As a fuel hydrogen produces only water on burning and is not toxic in any way. Photolytic processes are very attractive for hydrogen production due to the zero greenhouse gas emissions, however, they can be commercially used only if limitations related to low efficiency and poor stability can be resolved. In this work we describe a novel cell structure for stable photo electrochemical water splitting that can be prepared by electrodeposition from ionic liquids at high temperature. The deposition methods developed here provide low cost and efficient way to synthesise high quality semiconductors and their alloys. The concept presented in this work can potentially be applied to a variety of efficient, yet unstable systems to achieve efficient and long lasting water splitting.
