A Study on the Propulsion Performance in the Actual Sea by means of Full-scale Experiments [PDF]
TransNav, 2013 The IMO has adopted Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP) and Energy Efficiency Operational Indicator (EEOI) in order to reduce GHG emissions from international shipping.

Activity-controlled clogging and unclogging of microchannels
Physical Review Research, 2020 We propose a mechanism to control the formation of stable obstructions in two-dimensional microchannels of variable sections taking advantage of the peculiar clustering property of active systems.

Numerical Investigation of Self-Propulsion Performance and Noise Level of DARPA Suboff Model
Journal of Marine Science and Engineering, 2023 Propulsion noise is an enduring problem of significant military and environmental importance. Hence, it is crucial to investigate propeller noise characteristics.

Self-Propulsion of Chemically Active Droplets
Annual Review of Fluid Mechanics, 2023 Microscopic active droplets are able to swim autonomously in viscous flows. This puzzling feature stems from solute exchanges with the surrounding fluid via surface reactions or their spontaneous solubilization and from the interfacial flows resulting from these solutes’ gradients.

Spiral Thermal Waves Generated by Self-Propelled Camphor Boats
Condensed Matter, 2020 Spiral thermal surface waves arising from self-propulsion of the camphor-driven objects are reported. Spiral thermal waves were registered for dissolution and evaporation-guided self-propulsion.

Self-propulsive active nematics [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering SciencesIncreasing evidence suggests that active matter exhibits instances of mixed symmetry that cannot be fully described by either polar or nematic formalism. Here, we introduce a minimal model that integrates self-propulsion into the active nematic framework.

Encapsulation of fibrinogen and thrombin with calcium carbonate for hemorrhage control [PDF]
Biofunctional Materials, 2023 Hemorrhage remains the major cause of death in combat and civilian trauma, although significant advances in hemostatic agents and blood products have enhanced damage control resuscitation and reduced mortality. Currently, few hemostats are available for

Globule-like conformation and enhanced diffusion of active polymers [PDF]
, 2018 We study the dynamics and conformation of polymers composed by active monomers. By means of Brownian dynamics simulations we show that when the direction of the self-propulsion of each monomer is aligned with the backbone, the polymer undergoes a coil-to-

A minimal robophysical model of quadriflagellate self-propulsion [PDF]
Bioinspiration & Biomimetics, 2021 AbstractLocomotion at the microscale is remarkably sophisticated. Microorganisms have evolved diverse strategies to move within highly viscous environments, using deformable, propulsion-generating appendages such as cilia and flagella to drive helical or undulatory motion.
