The document describes a new industrial unit for laser treatment of nano and micro materials. The unit consists of a circular metal base with a motor, rectangular holder with adjustable cavities for samples, and barriers to control the laser beam. Samples of fiberglass were irradiated using Nd-YAG and argon lasers, and measurements showed the hardness increased after treatment. The unit provides a scalable method for homogeneous laser irradiation of powders and allows controlling parameters like laser type, particle size, and number of pulses to optimize the process.New tend in m ining & industrial waste recycling

This document discusses recycling and environmental protection. It summarizes the use of various waste materials like marble, granite, metal slag, and black sand waste. It then provides details on basalt, describing it as a hard, black volcanic rock composed of minerals like olivine and pyroxene. New paints have been developed using natural and melted basalt as pigments by incorporating their micro and nano-particles. The chemical compositions of natural and melted basalt are also examined. Finally, it briefly mentions mining waste and thermoplastic recycling.Zero 2013-building

The document describes a laser indirect exposure method for treating nanomaterials. The method involves dipping powder materials in a transparent plastic to allow laser beams to pass through without being absorbed. This indirectly exposes the powder to laser irradiation, improving its mechanical properties. After exposure, an organic solvent is used to remove the treated nanomaterials from the transparent plastic. The method physically improves properties without pollution and does not waste treated materials. It was found to improve hardness and modify Raman spectra of treated materials.Hebatalrahman zeolite

The document discusses a method for improving the mechanical properties of nano and micro materials using laser irradiation. The method involves embedding powder materials in a transparent plastic to allow laser beams to pass through without being absorbed by the plastic. After irradiation, an organic solvent is used to separate the treated materials from the plastic. Raman spectroscopy and hardness tests showed that the laser treatment improved the mechanical properties by storing photon energy in the material's structure in a similar way to cold working. The method provides a physical, non-polluting way to enhance materials that does not cause economic losses.

Black sand is sand that is black in color. It forms from a number of different dark sand grains, often containing iron which gives it a black color and heavy weight. Black sand in Egypt is found along coastal areas and contains economic minerals such as ilmenite, magnetite, garnet, zircon, rutile, and monazite. Black sand has a variety of applications including in the iron and steel, painting, titanium, aluminum, concrete, composite materials, insulation, and nanotechnology industries. However, some compounds in black sand have radioactive characteristics, so precautions must be taken when using it in building materials. Overall, black sand represents a valuable resource in Egypt that can be further utilized through new industries and.Nano road

Wear testing machine by laser ablation has been considered as a new method of wear testing which overcome the problems of old machines and systems . In this case, wear rate has occurred due to ablation by laser beam and test sample transformed from solid state to gas state directly (sublimation) and avoid relative movement and loss of material between sample and disk or plate. The different operation conditions such as temperature, chemicals, environmental conditions and different types of stresses has been considered. The new machine consists of two main parts optical and mechanical parts. The optical parts which include ultraviolet laser source, optical filter, lenses to concentrate the beam and manhole of laser beam to the sample tested in the control room. The mechanical parts includes The insulated chamber , dead weight , variable speed motor, sample holder, temperature and pressure sensor and ph meter. Mechanism of operation depend mainly on Ablation process which is removal of material from the surface of an tested object by vaporization .Ultraviolet laser beam is used as source of energy required for ablation process to avoid thermal effects. The new technique is suitable for all kinds of materials such as metals, alloys polymers, ceramics and composites in any shapes and sizes. The main factors affecting the new techniques are divided into factors related to the laser beam characteristics and factors related to material properties, the material properties include the surface roughness, thermal conductivity, specific heat ,density and mainly latent heat of sublimation.Zeolite
