Tiny bubbles can solve large problems. Microbubbles — around 1-50 micrometers in diameter — have widespread applications. They’re used for drug delivery, membrane cleaning, biofilm control, and water treatment. They’ve been applied as actuators in lab-on-a-chip devices for microfluidic mixing, ink-jet printing, and logic circuitry, and in photonics lithography and optical resonators. And they’ve contributed remarkably to biomedical imaging and applications like DNA trapping and manipulation.
Given the broad range of applications for microbubbles, many methods for generating them have been developed, including air stream compression to dissolve air into liquid, ultrasound to induce bubbles in water, and laser pulses to expose substrates immersed in liquids. However, these bubbles tend to be randomly dispersed in liquid and rather unstable.
According to Baohua Jia, professor and founding director of the Centre for Translational Atomaterials at Swinburne University of Technology, “For applications requiring precise bubble position and size, as well as high
Smule’s AutoRap goes live with Lenses, powered by the Snap Camera, bringing Snap’s AR innovations to Smule’s music-first community
Smule Inc., the global leader in interactive music creation, today announced its integration with Snap to bring imaging and augmented reality (AR) capabilities directly into the Smule app ecosystem, starting with hip-hop music app AutoRap. Smule has integrated Lenses, powered by Snap Camera Kit, showcasing the potential of AR to create even more engaging musical performances through dynamic visual elements.
Smule and Snap are bringing together the best of social music and digital imaging to offer both user bases even more immersive experiences. AutoRap, Smule’s recently revamped app for hip-hop enthusiasts, rappers and beat makers, is a fitting launch pad for the new Lenses, considering the significant role that creativity and individualism play in the genre.
A team of engineers, data scientists and content creators have come together to produce a camera that it says marries the quality of Micro Four Thirds with the artificial intelligence of a smartphone to ‘change and challenge the concept of the digital camera for the next decade’. Alice is a camera that uses a MFT sensor and lens mount, and which is controlled by a smartphone app.
Similar to Sony’s QX10 camera announced back in 2013, Alice has no screen of its own, but uses a clamp on the rear to allow users to attach their phone for adjusting settings, previewing and reviewing images. The camera and phone will communicate using a 5GHz wireless connection while its creators say AI and computational drivers will offer ‘new capabilities and techniques for autofocusing, autoexposure, colour science and more.’
The idea was born out of an experience where a smartphone took a much
