Using a micropatterning technique, the architecture of actin networks is revealed to be influenced by the spatial organization of actin filament nucleation. Considering the geometric boundaries within live cells, implications in the realm of actin-induced cell functions are vast.
The discovery of a highly resistive ferrite magnet where a low magnetic field induces a ferroelectric polarization at room temperature is a key advance towards applications of magnetoelectric coupling.
The mechanisms by which chemically functionalized carbon nanotubes flow in blood and are excreted through the kidneys illustrate the unconventional behaviour of these fibrillar nanostructures, and the opportunities they offer as components for the design of advanced delivery vehicles.
A magnetically colour-tunable material is used to create colour-coded microparticles that can be manipulated using magnetic fields and are suitable for use in multiplex bioassays.
A new multiscale computational method that is capable of predicting solute strengthening of alloys without adjustable parameters may lead to the development of new engineering materials.
A conventional material used in magnetic tunnel junctions with in-plane magnetization can also be magnetized perpendicularly, offering new possibilities for high-performance memory and logic circuits.
A liquid/air interface provides an effective platform for organizing thin molecular layers that can be transferred to solid surfaces. It is now shown that liquid-interface assembly is effective for generating extensive membranes of binary nanocrystal superlattices.
As the First International Nanotechnology Congress hosted in Quito clearly corroborated, Ecuador is betting on nanotechnology as one of its proposed key investment areas. It is now up to decision-makers to make it happen.
A new material designed from first principles and subsequently synthesized and characterized in the laboratory may shed light on why there is much more matter than antimatter in the Universe.
Aluminium is regarded as a simple system in which to test for phenomena occurring at high pressure. Ab initio calculations now show that this metal undergoes a surprising transition to an incommensurate structure when it is subjected to extremely high pressures.
The functionalization of crystalline porous materials is frequently limited to groups inert to the microscopic structure. Photoconversion of dormant precursors into highly reactive species shines light on the problem.
Friction is rarely studied at high sliding speeds between surfaces. However, simulations now suggest that gold clusters on atomically flat graphite can enter a new regime of ballistic friction, featuring a peculiar anticorrelation between translation and rotation.
The versatility and potential of conjugated organic materials continues to amaze, with their unique — and sometimes unexpected — properties being continuously discovered and harnessed by scientists in an attempt to use them in functional devices.
Imprinting molecular memory on the surface of polymer nanoparticles creates artificial antibodies that can recognize and neutralize a toxic peptide in vivo.
