Organic Ice Resists

Nano Letters, 2017
Electron-beam lithography (EBL) is the backbone technology for patterning nanostructures and manufacturing nanodevices. It involves processing and handling synthetic resins in several steps, each requiring optimization and dedicated instrumentation in cleanroom environments. Here, we show that simple organic molecules, e.g.

Ice Resistance Calculation in Pack Ice Conditions

2020
With the decline of the Arctic sea ice cover, more and more marine transportation and oil production are moving into ice-covered waters. Pack ice conditions may be the most common scenario for the ice-going ships in airworthiness seasons, except the icebreaker. During the ship advancing in pack ice conditions, the ice pieces will contact with the hull,

Numerical Simulation of the Ice Resistance in Pack Ice Conditions

International Journal of Computational Methods, 2019
In this study, the ice resistance of ship under the pack ice condition has been estimated using Multi-Material Arbitrary Lagrangian–Eulerian formulation and penalty-based fluid–structure interaction technique. Especially, the hydrodynamic loads occurring during the ship–ice interaction were combined in the numerical model, which could be important for

Humidity resistance of GaAs ICs

Proceedings of 1994 IEEE GaAs IC Symposium, 2005
A series of investigations into reliability effects of moisture on GaAs structures have lead to the conclusion that GaAs devices have resistance to degradation effects of humidity. This not only provides evidence that GaAs devices are ready for low-cost non-hermetic packages, but that GaAs ICs may have superior reliability performance compared to ...

Slip resistant properties of footwear on ice

Ergonomics, 2004
Current research on slipperiness of footwear has mainly focused on floors and lubricated floors. Slips and falls on icy and snowy surfaces involve not only outdoor workers, but also pedestrians and the general public; and occur in cold regions and in winter season in many parts of the world. However, in comparison with the size of the problem, research

Hydraulic resistance of river ice jams

Journal of Hydrodynamics, 2018
The hydraulic resistance of river ice jams consists of the resistance due to the seepage flow through the jam and the resistance due to the shear stress on the undersurface of the jam. Existing empirical formulations attributed the entire jam resistance to the undersurface resistance of the jam, but relate the jam resistance to jam thickness with ...

Effect of Bulbous Bow on Ice Resistance of Ice Ship

The Journal of Ocean, Mechanical and Aerospace -science and engineering- (JOMAse), 2018
Ice resistance is very important in design of an ice ship due to related to the propulsion system. Bulbous bow ship economically has advantage during sailing in open water due to lower resistance compared with an ice bow. On the other hand, the bulbous bow ship has higher ice resistance due to bulbous bow.

Thermal Resistance of IC Packages

IEEE Transactions on Broadcast and Television Receivers, 1973
Over the past few years, integrated circuit production has been dominated by the manufacture of digital circuits which typically operate at rather moderate power levels. For example, 5400 and 7400 series TTL circuits will dissipate approximately 150 mW.
