Switchable DNA mini-machines store information

They look like security gates, but change shape in a cascade.

New design improves performance of flexible wearable electronics

In a proof-of-concept study, engineers have designed a flexible thermoelectric energy harvester that has the potential to rival the effectiveness of existing power wearable electronic devices using body heat as the only source of energy.

Quantum thermometer or optical refrigerator?

Versatile optomechanical beams have potential applications in biology, chemistry, electronics.

Exosomes - biological nanoparticles offer significant potential in detecting and treating disease

Exosomes - biological nanoparticles which transfer information between cells - offer significant potential in detecting and treating disease, the most comprehensive overview so far of research in the field has concluded.

Holey pattern boosts coherence of nanomechanical membrane vibrations

Researchers have introduced a new type of nanomechanical resonator, in which a pattern of holes localizes vibrations to a small region in a 30 nm thick membrane. The pattern dramatically suppresses coupling to random fluctuations in the environment, boosting the vibrations' coherence.

Smooth propagation of spin waves using gold

The generation mechanism of spin wave noise and the suppression method.

Highly sensitive nanofiber-embedded touchscreens

Researchers have demonstrated the fabrication of transparent and flexible cellulose nanofiber films with high k values by incorporating ultralong metal nanofibers.

Spin liquids - back to the roots

Scientists report on a neutron experiment exposing experimental signatures of a low-temperature state predicted 44 years ago.

Nanosheets may produce more durable and longer lasting lithium-ion batteries

The team invented a generalized method of producing anode materials for lithium-ion batteries. The anodes are made from ultrathin metal oxide nanosheets, which are ultrathin, two-dimensional materials with excellent electrochemical and mechanical properties.

Gold nanocone array for regulating neuronal behavior

Researchers report the enhanced neurite outgrowth of rat primary cortical neurons on the periodic gold nanocone arrays created on the soft and flexible Teflon films.

New femto-camera with quadrillion fractions of a second resolution

Researchers have built a setup for recording holograms of tiny objects like living cells with a femtosecond speed. The new method allows one to reconstruct phase topography of a studied sample according to deformations that emerge in a laser pulse when it passes through the specimen.
