Resource Optimization & Advanced Technologies

Resource Optimization & Sustainable Practices

Features:

• Use of materials with decreased manufacturing waste.
• Use of materials that can be recycled.
• Decreased consumption of strategic materials.

Benefits of Resource Optimization

This approach, in turn, leads to:

• Replacement of metals and their alloys with polymers.
• Metal alloys offer superior mechanical resistance and better corrosion response.
• Increased use of new metals and light alloys.

Understanding Natural Resources

A natural resource is anything that humanity derives from nature to meet its needs.

Types of Natural Resources

Non-Renewable Resources

Resources that exist in limited quantities and can be exhausted, such as oil.

Renewable Resources

Resources that are not exhausted, such as wind and sunlight.

Potentially Renewable Resources

Resources that, even if consumed, are regenerated by nature.

Societal Impact on Resources

• While the economic and technological development of today's society provides social welfare, it also causes resource depletion. The compulsive consumption of goods is a primary cause of environmental degradation.

Advanced Technologies: Prosthetics & Cyborgs

Prosthetics Defined

A prosthesis is an artificial extension that replaces or provides a missing body part.

Cyborgs Defined

A cyborg is an organism that consists of organic matter and electronic or mechanical devices.

Nanotechnology: Scale & Applications

What is Nanotechnology?

Nanotechnology involves the design, production, and application of structures, devices, and systems by controlling shape and size at the nanoscale.

Architectural Innovations

• Coatings that protect glass walls or paint from graffiti.
• Liquid-repellent ceramic sanitary ware.
• Photochromic glasses that change color according to incident light.

Solar Energy Enhancements

• Photovoltaic solar energy is popular and attractive, but its high price remains a major drawback.

The Nanoscale Explained

The term 'nanotechnology' originates from the atomic scale, which is on the order of nanometers. A nanometer (nm) is a length of 10^-9 meters. At this scale, manipulating objects is challenging, primarily because the laws of physics and chemistry describing their behavior can vary significantly.
