Inefficiency [PDF]

open access: yes
We introduce an ordinal model of efficiency measurement. Our primitive is a notion of efficiency that is comparative, but not cardinal or absolute.

Fluctuating Curvature and Actuation in 4D Printed Asymmetric Networks by Frontal Photopolymerization

open access: yesAdvanced Materials Interfaces, EarlyView.
Asymmetric polymer networks, fabricated by frontal photopolymerization (FPP), are shown to exhibit curvature oscillations associated with monomer‐solvent exchanges during development and drying. We introduce a theoretical model for such dynamic curvature fluctuations and demonstrate the fabrication of bistable switches and self‐propelled materials that

Combinatorial Screening for Europium Induced Defect Engineering in Titania Anodic Memristors

open access: yesAdvanced Materials Interfaces, EarlyView.
A Ti‐Eu thin‐film combinatorial libary (3‐17 at.% Eu) was fabricated by co‐sputtering and anodisation. Systematic screening revealed forming‐free memristors with analog switching, with compositions between 7‐17 at.% Eu showing improved endurance and multilevel resistive states.

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

open access: yesAdvanced Materials Interfaces, EarlyView.
The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between

The Measurement of Intellectual Influence [PDF]

open access: yes
We examine the problem of measuring influence based on the information contained in the data on the communications between scholarly publications, judicial decisions, patents, web pages, and other entities.
