New microscope technique reveals details of droplet nucleation

Nucleation is a ubiquitous phenomenon that governs the formation of both droplets and bubbles in systems used for condensation, desalination, water splitting, crystal growth, and many other important industrial processes. Now, for the first time, a new microscopy technique developed at MIT and elsewhere allows the process to be observed directly in detail, which could facilitate the design of improved, more efficient surfaces for a variety of such processes.

Supernova surprise creates elemental mystery

Michigan State University (MSU) researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding stars known as supernovae.

Researchers improve the measurement of a fundamental physical constant

The validation and application of theories in physics require the measurement of universal values known as fundamental constants.

Biomedical engineers find active particles swim against the current

Researchers are beginning to understand the behavior of so-called "active" particles, which, if it can be controlled, has potential implications for engineered drug delivery systems and smart 3-D printing, according to an interdisciplinary Penn State research team.

Creating a next-generation photonic-electronic integration circuit

Global internet is growing at a compound rate of 24% per year, reaching 3.3 zettabytes per year by 2021. High-speed optical communication is urgently needed in this ever-connected world, and to keep up with this growth, developments in the fabrication of optical transceivers are sorely needed. Ph.D. candidate Xiao Liu, of the TU/e Department of Electrical Engineering, researched new ways to integrate the electronic circuits and photonic devices that make up optical transceivers. He will defend his Ph.D. thesis on 1 December 2020.

Scientists invent a new type of microscope that can see through an intact skull

Non-invasive microscopic techniques such as optical coherence microscopy and two-photon microscopy are commonly used for in vivo imaging of living tissues. When light passes through turbid materials such as biological tissues, two types of light are generated: ballistic photons and multiply scattered photons. The ballistic photons travel straight through the object without experiencing any deflection and hence are used to reconstruct the object image. On the other hand, the multiply scattered photons are generated via random deflections as the light passes through the material and show up as speckle noise in the reconstructed image. As the light propagates through increasing distances, the ratio between multiply scattered and ballistic photons increases drastically, thereby obscuring the image information. In addition to the noise generated by the multiply scattered light, optical aberration of ballistic light also causes contrast reduction and image blur during the image reconstruction process.

Photonics meets surface science in a cheap and accurate sensor for biological liquids

Skoltech researchers and their colleagues from Russia and Israel have come up with a new, simple and inexpensive method of testing liquid biological samples that can be further developed to work in clinical settings, including real-time testing during surgery. The paper was published in the journal Light: Science & Applications.

Natural three-dimensional nonlinear photonic crystal

Nonlinear photonic crystals (NPCs) are transparent materials that have a spatially uniform linear susceptibility, yet a periodically modulated quadratic nonlinear susceptibility. These engineered materials are used extensively for studying nonlinear wave dynamics and in many scientific and industrial applications. Over the past two decades, there has been a continuous effort to find a technique that will enable the construction of three-dimensional (3-D) NPCs. Such capability will enable many new schemes of manipulation and control of nonlinear optical interactions.

Best region for life on Mars was far below surface

The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes.

Chaotic early solar system collisions resembled 'asteroids' arcade game

One Friday evening in 1992, a meteorite ended a more than 150 million-mile journey by smashing into the trunk of a red Chevrolet Malibu in Peekskill, New York. The car's owner reported that the 30-pound remnant of the earliest days of our solar system was still warm and smelled of sulfur.

Scientists discover new way to measure turbulence of large planets and exoplanets

The swirls, eddies, and wavy bands of Jupiter and Saturn may remind us of a soothing, starry, starry night—but they reveal these two gas giants to be stormy, turbulent places. The turbulence produces energy cascades, a non-linear transfer of energy between different scales of motion. These are as fundamental to understanding planetary dynamics as the cardiovascular system is to understanding the human body.
