Abstract: In one example in accordance with the present disclosure, a printable ammonium-based chalcogenometalate fluid is described. The fluid includes an ammonium-based chalcogenometalate precursor. The printable ammonium-based chalcogenometalate fluid also includes an aqueous solvent and water. The printable ammonium-based chalcogenometalate fluid is printed onto a substrate. In the presence of heat, the aqueous solvent, water, and ammonium-based chalcogenometalate precursor break down to form a transition metal dichalcogenide having the form MX2.

Abstract: One example of a device includes a sensor, a memristor code comparator, and a controller. The sensor is to provide a sensor signal. The memristor code comparator is to compare the sensor signal to a reference signal. The controller is to determine a status of the sensor signal based on the comparison.

Abstract: A gas conduit directs a flow of gas from a gas flow source. A surface enhanced luminescence (SEL) stage is within the conduit and includes a substrate and nano fingers projecting from the substrate. A heater heats the nano fingers to a temperature so as to soften the nano fingers such that the nano fingers collapse towards each other to capture molecules entrained in the gas therebetween.

Abstract: Examples associated with user authentication are described. One example method includes authenticating a user of a device using a static authentication technique. A behavior profile associated with the user is loaded. The behavior profile describes a pattern of device usage behavior by the user in a three-dimensional space over a time slice. The behavior profile also identifies distinctive user habits. Usage of the device is monitored, and a behavior similarity index is periodically updated. The behavior similarity index describes a similarity between the usage of the device and the pattern of device usage behavior. The behavior similarity index is weighted based on the distinctive user habits. Access to the device is restricted when the behavior similarity index reaches a predefined threshold.

Abstract: One example of a device includes an antenna, a memristor code comparator, and a controller. The antenna is to receive a wake up signal. The memristor code comparator is to compare the wake up signal to a reference signal. The controller is to provide a trigger signal to wake up the device in response to the wake up signal matching the reference signal.

Abstract: Apparatus, systems, articles of manufacture, and methods to facilitate capacitive code comparing are disclosed. An example apparatus includes a comparator to receive a first portion of a first input and a second portion of a second input, the comparator including a capacitor. The example apparatus further includes a peripheral determination circuit to cause the capacitor to couple the first portion to the second portion; in response to coupling the first portion to the second portion, ground the capacitor; sense a current discharged by the grounded capacitor; and determine a Hamming distance of the first input and the second input based on the sensed current discharged by the capacitor.
