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 – [sciencedaily.com] 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 […]

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 […]

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 […]

Smart Nano-colloidal Metamaterials

Metamaterials have been getting recent press for their potential to create invisibility cloaks. Colloids are particle suspensions that have always been part of our lives (blood, milk, fog…) and operate at the nano level. Smart materials offer the ability to change their characteristics under control. Incorporating metamaterials into colloids will allow them to be deployed […]

Photonic Crystal Fibers

Photonic crystal fibers (PCFs) are microstructured optical fibers that use tiny air hole capillaries arranged in a pattern around the center of the fiber. This makes the light propagation far superior to conventional fibers, requiring fewer repeaters and less amplification over long distances. PCFs are also capable of handling high energy lasers efficiently. What is […]

Plasmons Used in Optical Communications

When ripples in the fluid-like free electrons in conducting metals form oscillations, they can act like virtual particles and are called “plasmons”, a category of quasiparticles. Controlling plasmons which interact with light allows fast and efficient modulation of light based communications. What is a plasmon? – [nanoscale.blogspot.com] A plasmon is a collective excitation of the […]
