Shaping Function: Polymeric 3D Systems With Unconventional Geometries for Biomedical Applications

Small, EarlyView.
Particle shape is a key design parameter governing biological interactions. Advances in fabrication enable precise control over anisotropy and compartmentalization, allowing modulation of cellular uptake, transport, and biodistribution, ultimately enhancing therapeutic performance. ABSTRACT Polymer geometry is a primary determinant of physical behavior

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Drops with non-circular footprints [PDF]

, 2015
In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. This type of drops is a consequence of the breakup processes occurring in thin films when anisotropic contact line motions take place.

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

European Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...
