soap bubble : a hollow iridescent globe formed by blowing a film of soapsuds (as from a pipe) — Webster
Soap bubble is an extremely thin film of soapy water enclosing air that forms a hollow sphere with an iridescent surface. Soap bubbles usually last for only a few seconds before bursting, either on their own or on contact with another object. They are often used for children’s enjoyment, but they are also used in artistic performances. Assembling several bubbles results in foam. When light shines onto a bubble it appears to change color. Unlike those seen in a rainbow, which arise from differential refraction, the colors seen in a soap bubble arise from interference of light reflecting off the front and back surfaces of the thin soap film. Depending on the thickness of the film, different colors interfere constructively and destructively. — Wikipedia

- Dry ice, the unsung hero of the COVID-19 vaccine...on March 22, 2021 at 8:27 pm
Robert Levis dumped chunks of a whitish substance into a beaker of water, and immediately the liquid began frothing and churning like a sorcerer's potion, spewing plumes of fog across the table of his office at Temple University.
- Why slow-pouring coffee makes a tower of liquid...on March 8, 2021 at 1:38 pm
When a droplet of coffee hits the liquid surface in the cup, a characteristic tower of coffee forms for a very short time, sometimes even with a new droplet on top. In a paper that appeared in Physical Review Fluids today, a team of researchers from Amsterdam, Delft and Paris shed new light on this intricate effect.

Using nanoscale quantum sensors, an international research team has succeeded in exploring certain previously uncharted physical properties of an antiferromagnetic material. Based on their results, the researchers developed a concept for a new storage medium published in the journal Nature Physics. The project was coordinated by researchers from the Department of Physics and the Swiss Nanoscience Institute at the University of Basel.
- Shuffling bubbles reveal how liquid foams evolveon February 8, 2021 at 5:33 pm
Foams are found everywhere, in soaps and detergents, meringues, beer foam, cosmetics and insulation for clothing and building. The application of foams tends to take advantage of their unique structure, which is why understanding how their structure can change over time is so important.
- Chemists synthesize 'flat' silicon compoundson December 22, 2020 at 7:37 pm
Chemists at the University of Bonn (Germany) have synthesized extremely unusual compounds. Their central building block is a silicon atom. Different from usual, however, is the arrangement of the four bonding partners of the atom, which are not in the form of a tetrahedron around it, but flat like a trapezoid. This arrangement is usually energetically extremely unfavorable, yet the molecules are very stable. Their properties are completely unknown so far; researchers now want to explore them. […]

Mechanical engineer Roberto Zenit spent the summer of 2019 trying to solve a problem that now plagues science departments around the world: How can hands-on fluid dynamics experiments, usually carried out in well-stocked lab rooms, be moved off campus? Since the pandemic hit, leading researchers like Zenit have found creative ways for students to explore flow at home.

Physics theory suggests that exotic excitations can exist in the form of bound states confined in the proximity of topological defects, for instance, in the case of Majorana zero modes that are trapped in vortices within topological superconducting materials. Better understanding these states could aid the development of new computational tools, including quantum technologies.

Physicists have created a broadband detector of terahertz radiation based on graphene. The device has potential for applications in communication and next-generation information transmission systems, security and medical equipment. The study came out in ACS Nano Letters.
- Thin-skinned solar panels printed with inkjeton August 27, 2020 at 12:20 pm
Solar cells can now be made so thin, light and flexible that they can rest on a soap bubble. The new cells, which efficiently capture energy from light, could offer an alternative way to power novel electronic devices, such as medical skin patches, where conventional energy sources are unsuitable.
- Ripple effects after slow-motion bubble collapseon August 17, 2020 at 3:20 pm
A recent feature cover photo on Science portrayed a bubble in mid-collapse, based on a study conducted by Alexandros T. Oratis et al. The research team in mechanical engineering, mathematics and aerospace engineering at Boston University, MIT and Princeton University demonstrated the formation of intriguing wave-like patterns when bubbles underwent collapse. Using a complex lighting setup and fast shutter speed in the lab, perfectly aligned to capture a fleeting moment, within one second, they […]
