Additive Manufacturing of Alumina‐Reinforced Elastomers
Advanced Engineering Materials, EarlyView.Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Resonant Pulsing Frequency Effect for Much Smaller Bubble Formation with Fluidic Oscillation
Energies, 2018 Microbubbles have several applications in gas-liquid contacting operations. Conventional production of microbubbles is energetically unfavourable since surface energy required to generate the bubbles is inversely proportional to the size of the bubble ...

Bubble size distribution and inner surface in a bubble flow [PDF]
AIP Conference Proceedings, 2017 This paper follows the reports [4] and gives instructions on how to theoretically determine the bubble size and its distribution using the distribution function of Nukiyama-Tanasawa with friction factors.

Advanced Engineering Materials, EarlyView.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Comparison of cavitation bubbles evolution in viscous media
EPJ Web of Conferences, 2018 There have been tried many types of liquids with different ranges of viscosity values that have been tested to form a single cavitation bubble. The purpose of these experiments was to observe the behaviour of cavitation bubbles in media with different ...

Fragmentation in turbulence by small eddies
Nature Communications, 2022 The classical framework of bubble fragmentation in turbulence usually only considers eddies of the bubble size. The authors present an experimental evidence that bubbles can be broken by the eddies of various sizes, supported by analytical model that ...

Experimental Investigation of Bubble Generation via Gas Injection Through Submerged Needles [PDF]
Journal of Applied Fluid MechanicsThe size of bubbles is a crucial parameter in gas-liquid bubbly systems, making the investigation of bubble formation essential for effective bubble size control. The authors experimentally examined bubble generation using a high-speed video camera. They
