A new way to check nanomaterial quality enters the ‘wild frontier’ industry

Posted on by Haptic

A new way to check the quality of nanomaterials like graphene has emerged from a team at the University of Sussex. Graphene and nanomaterials have been touted as wonder materials, and they are proving invaluable in all sorts of applications, such as in the automotive and aerospace industries, where heavy metals are replaced with lighter Read more about A new way to check nanomaterial quality enters the ‘wild frontier’ industry[…]

Self-cleaning wearable/washable electronics that are resistant to stains

Posted on by Haptic

New graphene printing technology can produce electronic circuits that are low-cost, flexible, highly conductive and water repellent. The nanotechnology “would lend enormous value to self-cleaning wearable/washable electronics that are resistant to stains, or ice and biofilm formation,” according to a recent paper describing the discovery. “We’re taking low-cost, inkjet-printed graphene and tuning it with a laser Read more about Self-cleaning wearable/washable electronics that are resistant to stains[…]

A team at FAU has Read more about Carbon nanostructures offer a lot of potential[…]

A new material can filter nanometer-sized molecules at 10 to 100 times the rate of commercial membranes

Posted on by Haptic

Dialysis, in the most general sense, is the process by which molecules filter out of one solution, by diffusing through a membrane, into a more dilute solution. Outside of hemodialysis, which removes waste from blood, scientists use dialysis to purify drugs, remove residue from chemical solutions, and isolate molecules for medical diagnosis, typically by allowing Read more about A new material can filter nanometer-sized molecules at 10 to 100 times the rate of commercial membranes[…]

3-D printed graphene foam

Posted on by Haptic

Nanotechnologists from Rice University and China’s Tianjin University have used 3-D laser printing to fabricate centimeter-sized objects of atomically thin graphene. The research could yield industrially useful quantities of bulk graphene and is described online in a new study in the American Chemical Society journal ACS Nano. “This study is a first of its kind,” Read more about 3-D printed graphene foam[…]

Graphene and Quantum Dots put in motion a CMOS-integrated camera that can see the invisible

Posted on by Haptic

Over the past 40 years, microelectronics has advanced by leaps and bounds thanks to silicon and CMOS (Complementary metal-oxide semiconductors) technology, making possible computing, smartphones, compact and low-cost digital cameras, as well as most of the electronic gadgets we rely on today. However, the diversification of this platform into applications other than microcircuits and visible Read more about Graphene and Quantum Dots put in motion a CMOS-integrated camera that can see the invisible[…]

A new 3D tactile sensor that could detect wide pressure ranges

Posted on by Haptic

A recent study, affiliated with UNIST has created a three-dimensional, tactile sensor that could detect wide pressure ranges from human body weight to a finger touch. This new sensor with transparent features is capable of generating an electrical signal based on the sensed touch actions, also, consumes far less electricity than conventional pressure sensors. The Read more about A new 3D tactile sensor that could detect wide pressure ranges[…]

Ultra-fast electronics with graphene

Posted on by Haptic

New experiments have shown that it is possible for extremely high currents to pass through graphene, a form of carbon. This allows imbalances in electric charge to be rapidly rectified. Once again, graphene has proven itself to be a rather special material: an international research team led by Professor Fritz Aumayr from the Institute of Read more about Ultra-fast electronics with graphene[…]

An easy way to make graphene for flexible and printable electronics

Posted on by Haptic

Rutgers University engineers have found a simple method for producing high-quality graphene that can be used in next-generation electronic and energy devices: bake the compound in a microwave oven. “This is a major advance in the graphene field,” said Manish Chhowalla, professor and associate chair in the Department of Materials Science and Engineering in Rutgers’ Read more about An easy way to make graphene for flexible and printable electronics[…]
