Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

Model-checking Quantitative Alternating-time Temporal Logic on One-counter Game Models [PDF]

open access: yes, 2014
We consider quantitative extensions of the alternating-time temporal logics ATL/ATLs called quantitative alternating-time temporal logics (QATL/QATLs) in which the value of a counter can be compared to constants using equality, inequality and modulo ...

Improved Optimization of Motion Primitives for Motion Planning in State Lattices

open access: yes, 2019
In this paper, we propose a framework for generating motion primitives for lattice-based motion planners automatically. Given a family of systems, the user only needs to specify which principle types of motions, which are here denoted maneuvers, that are

Polychlorinated biphenyls and organochlorine pesticides in Tiber River and Estuary: Occurrence, distribution and ecological risk [PDF]

open access: yes, 2016
The polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) pollution in the Tiber River and its environmental impact on the Tyrrhenian Sea (Central Mediterranean Sea) were estimated.

Pulsed Electrolysis Prevents Sulfur Poisoning for Sustained Sulfide Valorization

open access: yesAdvanced Materials, EarlyView.
Integrating pulsed electrolysis with Sc‐doped NiFe‐LDH enables sustainable sulfide valorization, achieving >500 h stability, 99.8% efficiency. Moreover, this technology produces high‐purity sulfur and sodium formate, boosting profit by 121% to $1,294.7 per tonne of hydrogen.

Observation of Three-dimensional Long-range Order in Smaller Ion Coulomb Crystals in an rf Trap

open access: yes, 2006
Three-dimensional long-range ordered structures in smaller and near-spherically symmetric Coulomb crystals of ^{40}Ca^+ ions confined in a linear rf Paul trap have been observed when the number of ions exceeds ~1000 ions.

Boosting Seawater Desalination by Ampere‐Level Nitrate Electroreduction On Defect‐Rich Ultrathin RuCu Alloy Nanostructures

open access: yesAdvanced Materials, EarlyView.
Defect engineering of ultrathin RuCu alloy nanostructures has been successfully achieved to enhance ammonia electrosynthesis under indutrial‐level current density. Simultaneously, the stable ampere‐level operation of nitrate electroreduction on defective RuCu nanostructures can drive seawater desalination at an ultrafast salt removal rate, offering an ...

Incremental evolution strategy for function optimization [PDF]

open access: yes, 2006
This paper presents a novel evolutionary approach for function optimization Incremental Evolution Strategy (IES). Two strategies are proposed. One is to evolve the input variables incrementally.

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

open access: yesAdvanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.
