Engineers develop room temperature, two-dimensional platform for quantum technology

Researchers have demonstrated a new hardware platform based on isolated electron spins in a two-dimensional material. The electrons are trapped by defects in sheets of hexagonal boron nitride, a one-atom-thick semiconductor material, and the researchers were able to optically detect the system's quantum states.

Researchers use X-rays to understand the flaws of battery fast charging

Researchers have imaged a battery as it was quickly charged and discharged, allowing for the observation of lithium plating behavior that can inhibit the battery's long-term function.

Next-generation optics in just two minutes of cooking time

One of the key building blocks of flexible photonic circuits and ultra-thin optics are metasurfaces. Engineers have now discovered a simple way of making these surfaces in just a few minutes -- without needing a clean room -- using a method already employed in manufacturing.

Quantum strangeness gives rise to new electronics

Quantum interference effects can cause substantial variation in the conductance properties of molecule-scale devices. By controlling the quantum interference, researchers showed that electrical conductance of a single molecule can be fine-tuned over two orders of magnitude.

Scientists build the smallest optical frequency comb to-date

Researchers built an integrated soliton microcomb operating at a repetition rate of 88 GHz using a chip-scale indium phosphide laser diode and the silicon nitride microresonator. At only 1 cubic cm in size, the device is the smallest of its kind to-date.

Researchers find way to stabilize color of light in halide perovskites

Physicists has found a way to stabilize the color of light being emitted from a promising class of next-generation materials that researchers believe could be the basis for efficient and more cost-effective optoelectronic technologies that can turn light into electricity or vice versa.

Researchers develop flags that generate energy from wind and sun

The novel wind and solar energy-harvesting flags have been developed using flexible piezoelectric strips and flexible photovoltaic cells.

Highly complex two-dimensional tessellation in the molecular world

Scientists have developed a method to construct highly complex molecular tessellations using a single molecular building block.
