Nanomagnets clean blood: Nanoscale article in Chemistry World

25 Jul 2013

Nanoparticles that never have to enter the body can capture harmful components in blood, scientists in Switzerland have shown.

Removing unwanted molecules from the blood is the most direct way to cure or prevent many illnesses. An example of this approach is dialysis where small molecules like urea are filtered out to treat patients with renal failure. As this separation method is size-selective, larger noxious molecules or cells cannot be efficiently eliminated from the blood in this way.

Nanoscale article in Chemistry World: Seawater-driven micromachines

24 Jun 2013

Seawater can be used as fuel to propel micromotors say scientists in the US. This finding eliminates the need for external fuels by enabling the micromotors to harvest energy from their surrounding environment.

Joseph Wang and his colleagues from the University of California, San Diego, have designed micromotors that consist of biodegradable and environmentally friendly magnesium microparticles and a nickel–gold bilayer patch for magnetic guidance and surface modification. Typically, ‘other catalytic microscale motors rely upon hydrogen peroxide as an external fuel source, but this requirement impedes many important applications for such tiny motors,’ explains Wang. Instead, these micromotors are fuelled by seawater and rely on the hydrogen bubble thrust generated from the magnesium–water reaction. ‘They [the micromotors] display efficient and prolonged propulsion in chloride-rich environments, like seawater, owing to the chloride pitting corrosion processes. The presence of the gold bilayer also enhances the magnesium–water reaction and leads to efficient motion in seawater,’ says Wang.

Nanoscale article in Chemistry World: Manipulating liquid metal marbles

22 May 2013

Sequential snaptshots of a liquid metal marble in motion when a voltage is applied

Researchers in Australia and Germany have made highly controllable actuators in the form of liquid metal marbles. The marbles have a nanoparticle coating that can be electrochemically manipulated to control their movement.

Actuation involves converting an input signal into motion to drive a mechanism or system. Micro- and nano-scale actuators are crucial components in consumer electronics, amongst other things.

Now, Shi-Yang Tang, under the supervision of Kourosh Kalantar-Zadeh and Arnan Mitchell, at RMIT University, Melbourne, has demonstrated that liquid metal marbles can act as actuators in aqueous media when an electrical current is applied. The marbles consist of a galinstan (an alloy of gallium, indium and tin) core that has been coated with tungsten oxide nanoparticles. An applied current causes the nanoparticles to migrate along the surface of the galinstan, creating an asymmetry in the surface tension that makes the marbles move.

Nanoscale article in Chemistry World: Origami electronics

08 May 2013

Lighting of an LED via folded paper printed with silver nanowire inks

We normally think of electronic components as being inflexible but researchers in Japan are challenging this concept by reinventing paper. And they’ve used their paper electronics to create origami-style lights.

Antennas transmit and receive information and although they have been put on paper before, none of these antennas have been foldable. This is because the conductive materials struggle to stay on the coarse and porous surface of the paper, resulting in deterioration of their electronic properties. Now, Masaya Nogi and co-workers at Osaka University, have combined smooth paper, made from mechanically nanofibrillated cellulose nanofibres, and silver nanowire inks to make foldable antennas. To demonstrate the effectiveness of the antennas the team folded the printed nanopaper into origami cranes and showed they could be used in the illumination of a light emitting diode.

Nanoscale article in Chemistry World: Inorganic nanosheet to enhance batteries

29 Apr 2013

A graphene inspired electrode material that could help batteries hold more power has been developed by Chinese scientists. The large surface area of these cobalt oxide nanosheets is key to their electrochemical performance.

Batteries are a cornerstone of modern life with most smartphones and laptops using rechargeable lithium ion batteries. As technology advances, the search is on for batteries that can pack more energy into the same space.

Graphitic electrodes are commonly used in lithium ion batteries but suffer from low theoretical capacity. A viable alternative is to use metal oxides which have significantly higher theoretical capacities but in practice are limited by their inability to hold more lithium ions. Recently nanostructures have been developed that can hold more lithium ions but the swelling and shrinking from charge–discharge cycles damages the electrode and greatly reduces its capacity, a problem known as pulverisation.
