Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Faith-Based Emergency Powers [PDF]

open access: yes, 2018
This Article explores an expanding phenomenon that it calls Faith-Based Emergency Powers. In the twenty-first century, conservatives have come to rely heavily on Faith-Based Emergency Powers as a legal strategy in the culture wars.

High‐Spatiotemporal‐Resolution Transparent Thermoelectric Temperature Sensor Arrays Reveal Temperature‐Dependent Windows for Reversible Photothermal Neuromodulation

open access: yesAdvanced Functional Materials, EarlyView.
Thermoelectric temperature sensors are developed that directly measure heat changes during optical‐based neural stimulation with millisecond precision. The sensors reveal the temperature windows for safe reversible neural modulation: 1.4–4.5 °C enables reversible neural inhibition, while temperatures above 6.1 °C cause permanent thermal damage.

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Security, Interventions, Distance, and Danger: New Publications, August 2015 [PDF]

open access: yes, 2015
A number of exciting open access publications have emerged from the Security in Transition team – a research programme which aims to conceptualise and empirically grasp the security gap both as a (perceived) reality and as a social mechanism within ...

Analisis Perceived Ease of Use, Perceived Security, Perceived Risk pada Pengguna Potensial Paylater di Kalangan Gen Z

open access: yesPENG: Jurnal Ekonomi dan Manajemen
This study aims to analyse the influence of perceived ease of use, perceived security, and perceived risk on user trust and intention to use a paylater service among Generation Z in Jakarta. A quantitative approach was employed using purposive sampling, and the data were analysed through Structural Equation Modelling (SEM) with the AMOS software ...

Charge‐Induced Morphing Gels for Bioinspired Actuation

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Flexicurity and Workers Well-Being in Europe: Is Temporary Employment Always Bad? [PDF]

open access: yes
In this paper we study the effect of a micro-level measure of flexicurity on workers job satisfaction. To this aim, using micro data from the Eurobarometer survey, we split workers in different groups according not only to their employment contract (i.e.

Multiple Twinning in Nacre and Aragonite

open access: yesAdvanced Functional Materials, EarlyView.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.
