There are two contents of this article. The first is briefly to review the experiment research on the catalysis mechanism of Carbon Gasification Reaction-CGR(C+CO2=2CO) from 60s -90s. The results show that the catalytic phenomenon is physical phenomenon rather than chemical, and the catalyst does not participate in the chemical reaction. The catalytic activity and selectivity of catalyst are related to the electronegativity or energy level of the catalyst. The second is to clarify the applications of CGR for save mankind. The lime is first proposed to capture CO2 in flue gas of power plant. The lime can be recycled. The coal is used to convert CO2 from cement steel produce into CO, producing both energy and lime and iron. The capture CO2 is used to treat waste such as firewood and plastic, eliminate white pollution. The author considers that using the CGR which has been used for a long time can solve the three problems which people worry about: energy exhaustion, environmental pollution and climate crisis.

A new type of foam fractionation column with spiral internal had been designed for enhancing the foam drainage and thus for the removal of minute hazardous materials. Chromium was separated from wastewater using the continuous foam separation method. According to the similar physical behavior of foam separation and chemical reaction processes, the equivalent chemical reaction constant was introduced, Establishment concentrate distributed mathematical model of the whole tower under the condition of continuous foam separation with SDS as active agent. The model has been tested by experiments. The result indicated that foam separation process could be regarded as a first order reaction, and diffusion coefficient was 4.86cm2/s.

The Impact

A novel mathematical model is envisioned discussing the magnetohydrodynamics (MHD) steady incompressible nanofluid flow with uniform free stream velocity over a thin needle in a permeable media. The flow analysis is performed in attendance of melting heat transfer with nonlinear chemical reaction. The novel model is examined at the surface with the slip boundary condition. The compatible transformations are affianced to attain the dimensionless equations system. Illustrations depicting the impact of distinct parameters versus all involved profiles are supported by requisite deliberations. It is perceived that the melting heat parameter has a declining effect on temperature profile while radial velocity enhances due to melting.

AbstractTwo major challenges that exist in order to utilize nanoparticles as building blocks for microelectronic and photonic applications are presented. The first challenge is how to make uniform nanoparticles in industrial-scale. The second challenge is how to convert these nano-building blocks to application forms such as device structures or coatings. In this paper, materials and processing guidelines to provide the solutions for these challenges are described on the basis of (a) laser-driven chemical reaction processes to generate a versatile range of nanoparticles having extremely narrow size distributions, and (b) unique organic-inorganic nanocomposites using surface engineering over nanoparticles. As promising applications, direct deposition of nanoparticles and nanocomposites are discussed in conjunction with planar lightwave devices, photonic nanocomposites for the refractive index engineering, and planarization processes for electronic chips.
