Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

Advanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Three-dimensional Orbit and Dynamical Masses of GJ 105 AC

The Astrophysical Journal
The precision of stellar models is higher than the precision at which we are able to measure the masses of most stars, with the notable exception of binaries where we can determine dynamical masses of the component stars.

Low‐Voltage Operation of IGZO Memtransistors Enabled by Coupling Enhancement Through 2T Drain‐Driven Operation for Neuromorphic Computing

Advanced Intelligent Systems, EarlyView.
A two‐terminal IGZO memtransistor enabling low‐voltage operation is demonstrated through coupling enhancement. By utilizing drain‐induced Fowler–Nordheim tunneling, the device achieves programming below 10 V with a large memory window and high on/off ratio.

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

SOLIFLY Public Workshop - Decarbonizing aviation – Role of batteries & Developing aeronautic structural batteries in Clean Sky 2 SOLIFLY

, 2023
Batteries play a key role in decarbonization of air transport as they offer highest energy efficiency with Li-ion staying the dominant technology in mobility  applications by 2030. Structural batteries, i.e. multifunctional energy storage, while still at low TRL, have the potential to overcome the limiting weight penalty of monofunctional batteries ...

Cooling Holes in Polymer Spur Gears: A Critical Analysis of Heat Dissipation Benefits and Mesh Stiffness Penalties

Journal of Applied Polymer Science, EarlyView.
Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

SERS Sensor Chips Based on Nanosphere Lithography on Flexible Platforms for the Detection of Chemicals, Pesticides and Nucleotides

Advanced Physics Research, EarlyView.
In this paper, we propose an efficient and scalable method for creating high‐performance, flexible surface‐enhanced Raman scattering (SERS) substrates using gap‐tunable nanosphere lithography on flexible substrates such as Kapton and PET. The applicability of the SERS sensor chips for diverse applications was demonstrated by its ability to detect ...
