Atomically thin light-emitting device opens the possibility for 'invisible' displays

A bright-light emitting device that is millimetres wide and fully transparent when turned off has been built by a team of engineers at the University of California (UC), Berkeley. The light emitting material is a monolayer semiconductor, which is just three atoms thick.  According to the team, this discovery could pave the way in creating invisible displays – that would be bright when on, but see-through when off – on walls and windows or in applications such as light-emit...

Physicists reveal material for high-speed quantum internet
Physicists reveal material for high-speed quantum internet

As the race for quantum computing continues, so does the development into quantum technologies targeted to neturalise the threat of hacking. Classical cryptographic algorithms are complexity-based and can remain secure only for a certain period of time. Unlike its classical counterpart, quantum cryptography relies on the fundamental laws of physics and is thought to be capable of guaranteeing security of data transmission forever. The operation principle is based on the fact an unknown ...

Next-gen optical disk to solve data storage challenge
Next-gen optical disk to solve data storage challenge

Using gold nanomaterials combined with a hybrid glass material, scientists from from RMIT University and the Wuhan Institute of Technology say they have demonstrated a new type of high-capacity optical disk that can hold data securely for more than 600 years.  This gold-generated next-generation optical disk is said to have up to 10TB capacity - a storage leap of 400% and a six-century lifespan. According to the team, it has the potential to offer a more cost-efficient and sust...

Xilinx looks beyond FPGAs and unveils new product category - ACAP
Xilinx looks beyond FPGAs and unveils new product category - ACAP

Xilinx has announced, what it describes as, a new breakthrough product category called Adaptive Compute Acceleration Platform (ACAP) that provides capabilities significantly beyond that of an FPGA. An ACAP is a highly integrated multi-core heterogeneous compute platform that can be changed at the hardware level to adapt to the needs of a wide range of applications and workloads and can be done dynamically during operation. The ACAP is intended to accelerate a broad set of applications i...

Sensors make Sense. For Arduino and more

Sensors are either analog or digital. Analog values are read in via an A-D input, whereas for digital signals a simple Port connection frequently adequate. In some cases, however, sensors have dual outputs, one analog and one digital. A glance ...
