Smart materials
Smart materials are materials that can change one or more properties in response to external stimuli like temperature, electric charge, or magnetic fields. Some examples of smart materials include piezoelectric materials, shape memory alloys, and pH-sensitive polymers. Smart materials have existed for around 50 years but are now being widely exploited for their useful properties. Common applications of smart materials include use in aerospace, civil engineering, and mechatronics.
Introduction to smart materials
Hello guys! This slide gives a quick guidance about what 'smart materials' are and also about it's types, application and many more. I hope my presentation was helpful for you all.

Smart materials presentation
The document discusses smart materials, which are materials that respond to environmental stimuli like temperature, pressure, or light. Smart materials are classified into several types including piezoelectric, shape memory alloys, and thermoresponsive materials. Shape memory alloys can remember their original shape and return to it after being deformed, due to a change in crystalline structure between martensite and austenite phases in response to temperature changes. The document outlines various applications of smart materials in areas like aircraft, orthopedics, dentistry, robotics, and smart glass.
Smart material
This document discusses shape memory alloys (SMAs), specifically focusing on nickel-titanium (Ni-Ti) alloys. It defines SMAs as materials that can return to a predetermined shape after deformation through heating or cooling. SMAs exist in two phases, austenite and martensite, and transition between the phases through temperature changes, allowing the material to change shape. Common applications of Ni-Ti SMAs include uses in biomedical devices, robotics, and sensors due to properties like biocompatibility and high strain recovery. The document compares Ni-Ti SMAs to other materials like copper-based SMAs and stainless steel.

Huge savings on the surface
Fouling on heat exchangers involves the buildup of unwanted materials like bacteria, organic matter, and minerals on surfaces in contact with liquid. This fouling layer inhibits heat transfer and requires frequent cleaning, increasing costs. Conventional antifouling coatings are too thick and reduce heat transfer efficiency. The new research project aims to develop a novel antifouling coating that maintains heat transfer efficiency while preventing fouling through anti-adhesive, anti-scaling, and anti-microbial properties. This coating could decrease maintenance time by three to four times, providing large financial savings for companies through lower maintenance and energy costs while also benefiting the environment.

Composites
This document provides information on composite materials and nanomaterials. It defines composites as materials formed by combining two or more materials with different properties. Most composites contain a matrix that binds together a reinforcement material. Composites provide strength and stiffness while being lightweight. They also allow for design flexibility. Nanomaterials exhibit novel properties at the nanoscale, such as optical and catalytic properties, due to increased surface area to volume ratio. Fullerenes and carbon nanotubes are examples of nanomaterials that are of interest for their mechanical and electrical properties.

Strength to Weight Ratio is an important factor in this design.
Aluminum has a higher Strength to Weight Ratio than steel, making it lighter. However, polymers like polyethylene are even lighter than aluminum and can be easily molded.
While both aluminum and polyethylene meet the design requirements, polyethylene is lower in cost and lighter. Therefore, polyethylene would be the best choice of material for the soda drink container design. Its light weight, high strength, corrosion resistance and low manufacturing cost make it suitable to produce large volumes of containers economically.

Composite materials are formed by combining two or more materials with different properties. The materials do not dissolve into each other but work together to produce unique properties in the composite. Most composites contain a matrix that binds and surrounds a reinforcement material. This combination of materials produces strength, stiffness, and lightness. Modern aviation relies heavily on composite materials for their aircraft due to these advantages over traditional metals.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
