Graphene-Based Wearables for Health Monitoring

ICFO's fitness band is being developed to measure heart rate, hydration, oxygen saturation, breathing rate and temperature.

The first of ICFO's devices on display will allow customers to monitor their level of exposure to sunlight through a UV sensor. Designed as a flexible, transparent and disposable patch, it connects to a mobile device and alerts the user once he or she has reached a defined threshold of sun exposure. Using

Bigger Teams Aren't Always Better in Science and Tech

A forest of trees where each tree is a project and a person supports the kind of deep searching (roots) and highly disruptive (branches) work produced by small teams.

In today's science and business worlds, it's increasingly common to hear that solving big problems requires a big team. But a new analysis of more than 65 million papers, patents and software projects found that smaller teams produce much more disruptive and innovative research. In a new paper published

Laser-Induced Graphene Gets Tough, With Help

Rice University scientists have combined laser-induced graphene with a variety of materials to make robust composites for a variety of applications.

HOUSTON - Laser-induced graphene (LIG), a flaky foam of the atom-thick carbon, has many interesting properties on its own but gains new powers as part of a composite. The labs of Rice University chemist James Tour and Christopher Arnusch, a professor at Ben-Gurion University of the Negev in Israel,

Scientists Discover New Type of Magnet

In a normal magnetic material, dense magnetic moments try to align with their neighbors (left). By contrast, in a singlet-based material, unstable magnetic moments pop in and out of existence, and stick to one another in aligned clumps (right).

A team of scientists has discovered the first robust example of a new type of magnet--one that holds promise for enhancing the performance of data storage technologies. This "singlet-based" magnet differs from conventional magnets, in which small magnetic constituents align with one another

Electrocatalyst Outperforms Platinum in Hydrogen Production

The novel catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix. Electron microscopy of carbon nanowires co-doped with ruthenium and nitrogen showed ruthenium nanoparticles decorating the surface of the nanowires.

A novel ruthenium-based catalyst developed at UC Santa Cruz has shown markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen

Ferroelectric Polymers Made More Versatile

A block copolymer of PVDF (black) and an insulating polymer chain (blue) form a block copolymer. Through phase separation, the blocks assemble in films. The dielectric properties can be tuned by varying composition and length of the blocks.

The ferroelectric polymer PVDF (polyvinylidene fluoride) has interesting properties and could be used to store information or energy. One of the main drawbacks of PVDF is that if you add extra functional groups to improve certain properties, this also interferes with its ferroelectricity. To solve this, scientists

Observing Hydrogen's Effects in Metal
Hydrogen, the second-tiniest of all atoms, can penetrate right into the crystal structure of a solid metal. That's good news for efforts to store hydrogen fuel safely within the metal itself, but it's bad news for structures such as the pressure vessels in nuclear plants, where hydrogen uptake eventually
