Fractal Acoustic Metamaterials with Subwavelength and Broadband Sound Insulation
Shock and Vibration, 2019 We construct new fractal acoustic metamaterials by coiling up space, which can allow subwavelength-scale and broadband sound insulation to be achieved.

Effects of Spaceflight on Human Induced Pluripotent Stem Cell-Derived Cardiomyocyte Structure and Function. [PDF]
, 2019 With extended stays aboard the International Space Station (ISS) becoming commonplace, there is a need to better understand the effects of microgravity on cardiac function. We utilized human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs)

Long term time-lapse microgravity and geotechnical monitoring of relict salt-mines, Marston, Cheshire, UK. [PDF]
, 2012 The area around the town of Northwich in Cheshire, U. K., has a long history of catastrophic ground subsidence caused by a combination of natural dissolution and collapsing abandoned mine workings within the underlying Triassic halite bedrock geology. In

Revista Brasileira de Ensino de Física, 2016 Some experimental activities of low cost and easy accomplishment are proposed to reproduce the microgravity environment that exists in space ships, free fall towers and parabolic flights. The objective is to provide didactical material to aid teachers in terms of assembling instructions, besides the implementation of these experiments and explanation ...

Performance and Modeling of a Two-Stage Light Gas Gun Driven by Gaseous Detonation
Applied Sciences, 2020 A two-stage light gas gun driven by gaseous detonation was newly constructed, which can make up for the disadvantages of the insufficient driving capability of high-pressure gas and the constraints of gunpowder.

Granular piston-probing in microgravity: powder compression, from densification to jamming [PDF]
, 2022 The macroscopic response of granular solids is determined by the microscopic fabric of force chains, which, in turn, is intimately linked to the history of the solid. To query the influence of gravity on powder flow-behavior, a granular material is subjected to compression by a piston in a closed container, on-ground and in microgravity.

Simulated microgravity compromises mouse oocyte maturation by disrupting meiotic spindle organization and inducing cytoplasmic blebbing. [PDF]
PLoS ONE, 2011 In the present study, we discovered that mouse oocyte maturation was inhibited by simulated microgravity via disturbing spindle organization. We cultured mouse oocytes under microgravity condition simulated by NASA's rotary cell culture system, examined ...

Cavitation Bubble Dynamics inside Liquid Drops in Microgravity [PDF]
PRL 97, 094502 (2006), 2006 We studied spark-generated cavitation bubbles inside water drops produced in microgravity. High-speed visualizations disclosed unique effects of the spherical and nearly isolated liquid volume. In particular, (1) toroidally collapsing bubbles generate two liquid jets escaping from the drop, and the "splash jet" discloses a remarkable broadening.

Spreading of droplets under various gravitational accelerations [PDF]
, 2022 We describe a setup to perform systematic studies on the spreading of droplets of complex fluids under microgravity conditions. Tweaking the gravitational acceleration under which droplets are deposited provides access to different regimes of the spreading dynamics, quantified through the Bond number.
