New Composites Formed Using Magnetic Particles

Composites are made by combining two different materials with different properties: Concrete – concrete by itself is a composite of cement and crushed rock, which has a high strength against compression or crushing (like rock) but can be poured like a liquid into forms to create specific shapes before it hardens. Concrete does not have [...]

Online Course on NanoElectronics

Purdue University is offering a new two part course on NanoElectronics starting in January. Each part will last five weeks and costs a $30 registration fee. You can either simply audit the class and not take the tests, or you can take the tests and by passing, earn a completion certificate. If you pass the [...]

Graphene Walls – Walls of Graphene

Putting 100 trillion Field Effect Transistors (FETs) on a one square centimeter chip may become possible using graphene walls. The term “graphene walls” in this context describes tiny strips or “nano-ribbons” of carbon atoms. Other researchers have developed ideas for creating cheap and flexible lighting and display substrates made of graphene components embedded in plastic. [...]

Super Hard Cubic Aluminum

Aluminum oxide (Al2-O3) in it’s crystalline form is known as corundum and is second to diamond on the hardness scale. When it includes traces of chromium, creating a red color, it is called ruby and with traces of chromium, titanium, iron or other elements creating other colors, it is called sapphire. Creating the Heart of [...]

Harvesting Ambient Energy

The word, “ambient” means, “from the surrounding environment”. It can mean either something that is found in the surrounding environment or something in the environment that surrounds. We have been harvesting energy from the surrounding environment from before the first glimmerings of civilization. Collecting fire from a lightening strike, damming and redirecting water, water wheels, [...]

Micro Robot Dragonfly

Students from Texas Tech University have won the “Novel Design” category in the “MEMS University Alliance Design Competition” sponsored by Sandia National Labs with a design for a dust mite sized dragonfly. “MEMS” stands for Micro Electro Mechanical Systems and deals with the technology of very small electro mechanical devices. MICROBOTIC Dragonfly – [sandia.gov] I. [...]

Electronic Textiles

From a low end of sowing and weaving electronic components into cloth for simple purposes to manufacturing cloth with electronic components embedded in the woven threads, the range of electronic textiles is wide and growing fast. Thread that generates and stores electric power from solar energy may be next. Towards electronic textiles – putting conductive [...]

Photonic Colloidal Crystals

A colloid is a suspension or dispersion of one substance inside another, typically held in place by electromagnetic fields. Examples of common colloids include, blood, milk, ink, gelatin, smoke and fog particles. Destabilizing the electromagnetic field often causes the particles to precipitate out of their suspended state. Colloidal particles can also self-assemble or crystallize into [...]

1918 – Feynman – bio

Richard Feynman was born in 1918 in New York, USA and was a physicist. He was one of the founders of quantum electrodynamics and invented a shorthand to show particle interactions now known as “Feynman diagrams”. In 1965, he won a Nobel prize for his work in quantum electrodynamics, along with Julian Schwinger and Sin-Itiro [...]

Microcarriers Deliver Anti-Cancer Drug

Tiny anti-cancer drug delivery capsules are guided to a target inside a human body using an MRI system. Localized delivery of an anti-cancer drug by remote-controlled microcarriers – [polymtl.ca] Soon, drug delivery that precisely targets cancerous cells without exposing the healthy surrounding tissue to the medication’s toxic effects will no longer be an oncologist’s dream [...]
