Nano Neural Networks

Current neural networks are software constructs that run on computing devices. A new approach suggests the possibility of building neural networks into hardware using the structure of nanomaterials. AI implications: Engineer’s model lays groundwork for machine-learning device – [] In what could be a small step for science potentially leading to a breakthrough, an engineer […]

Ceramic Aerogel Composite

Atomic layer deposition grows thin film layers of materials using sequential exposure of a substrate to gas molecules. Researchers at Purdue University are using a graphene aerogel substrate and depositing thin layers of aluminum oxide ceramic to create a new material that is light, elastic, strong, conductive, and offers thermal insulation. This has excellent potential […]

Chain Mail Metamaterials

Metamaterials have the ability to create new properties because of the way they are structured instead of the properties being simply dependent on the materials that are used. Most metals are good conductors and have well known colors based on the wavelength of light they reflect. But if structures are formed in the metal that […]

Self Assembly of Diamond Nanothreads

Most parts of our universe self assemble in some form, but it often takes place in a random or even chaotic manner. When scientists talk about self assembly, they usually are discussing techniques designed to guide the assembly process into producing a specific result. Crystals are collections of atoms that have self assembled into predetermined […]

Carbon Nanotube Electronics

Carbon NanoTubes (CNT) are structures made from carbon atoms arranged in a lattice that is rolled up into a tube shape. Like silicon, carbon can act as a semiconductor and this allows it to be used in making small electronic components. We are just beginning to learn how to use carbon nanotubes in electronics, but […]

Malleable Morphing Materials

Claytronics is a conceptual cross-section between nanotechnology and programmable robotics. Add in 3D printing and we’re talking about using digital processing to create programmable materials that can change form. Create Anything You Want With Programmable Matter – [] What if you could fax someone a real, three-dimensional object? The solution might come in the form […]

Thin Strong Corrugated Aluminum Oxide

We are most familiar with aluminum oxide as corundum, a crystalline mineral. Corundum, combined with various impurities, form the gemstones ruby and sapphire. Many forms of aluminum oxide are considered to be ceramics, with typical characteristics of being hard, brittle and good insulators. University of Pennsylvania researchers have discovered that by using atomic layer deposition […]

Smart Stuff

We are building intelligence into a constantly expanding list of everyday household items. It started with smart phones, and we now have smart meters, smart light bulbs, smart locks, smart watches, smart clothing and smart appliances and gadgets of all types. Any device that can use sensors to collect data, make decisions about how to […]

Soldier, Heal Thyself

An old proverb, “Cura te ipsum” (Latin), means “Physician, heal thyself”. DARPA is beginning work on a project that will enhance the ability of the human body to heal itself. The project will focus first on mapping the neural pathways involved in disease and injury and then on investigating the potential of modulating nerve activity […]

Taking Pills That Contain Nanotechnology

Carefully targeted and controlled delivery of substances into our bodies can be accomplished using nanotechnology containers. The containers can be routed to specific areas or tissues and can release materials at either a certain place or a certain time or span of time. Drugs, vitamins, oxygen, sensors, and more materials can be delivered in this […]
