Albert Einstein was much more than a scientific genius. From his political beliefs to his hatred of socks, here are 32 facts about Einstein you might not have heard before.

A new compact, lightweight, gel-free and waterproof electrocardiogram (ECG) sensor offers more comfort and less skin irritation, compared to similar heart monitoring devices on the market. ECGs help manage cardiovascular disease – which affects around 4 million Australians and kills more than 100 people every day – by alerting users to seek medical care.

AI Adoption Slow For Design Tools Kapoor, A., Lin, R., & Green, W. M. . Power, complexity, and scaling of photonic integrated circuits. Applied Physics Reviews, 6, 031307. ...

Holograms are often displayed in science fiction as colorful, life-sized projections. But what seems like the technology of the future is actually the technology of the present. In Applied Physics Reviews, by AIP Publishing, researchers developed an acoustic metasurface-based holography technique that uses a deep learning algorithm to generate and iteratively improve a hologram of the Mona Lisa.

Tracing volatile organic compounds is important for public safety and all “smell” related issues. To this end, in Applied Physics Reviews, Liu et al. introduce a fluid mechanics-based chamber design for an electronic nose that consistently detects VOCs at low concentrations. The strategy, which includes using a shuntlike device to control the behavior of fluid flow, is a step forward in e-nose technology development.

Studying ferroelectric materials can be done with the help of piezoresponse force microscopy (PFM), due to the sensitivity and nanometer-level resolution it inherits from AFM. Bruker discusses the best modes and practices in regards to PFM measurements in a new application note.

Electron microscopes have played a pivotal role in developing nanotechnologies as their high spatial resolutions make it possible to visualize the smallest of structures.

This article looks at how laser-based ultrasounds can be used to enhance 3D printing processes.

Researchers have confirmed the chemical inertness of PtSe2 surfaces to ambient gases (oxygen and water) and, as a result, the long-term durability of PtSe2-based devices using synchrotron-based surface-science methods.

Researchers have built a thermoelectric generator that generates electricity from the difference in temperature between the PV cell and the surrounding environment. This research has been published in Applied Physics Letters.
