A Colloidal Quantum Dot Thermistor and Bolometer

open access: yesAdvanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Military equipment [PDF]

open access: yes, 2018
The basic weapon of any Roman soldier was a short sword – gladius. Since Roman army fought in a compact formation in which every soldier had a specific, predetermined task, there was not enough space for any individual to fight using a long weapon. A relatively small length of about 65 cm made skillful gladius hand-to-hand combat possible and also ...

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

open access: yesAdvanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
