Temperature‐Driven Emission Redistribution of Yb2+ in SrB4O7 Enables Highly Sensitive Optical Thermometry Supported by Multiple Linear Regression

open access: yesAdvanced Science, EarlyView.
A novel optical thermometer exploits the rare UV emission of Yb2+ ions in a SrB4O7 host, enabling highly sensitive, non‐contact temperature measurements from 80 to 420 K. The applied multiple linear regression (MLR) analysis results in a multiple increase in the resulting temperature sensitivity.

Assessment of the infrared welding process for a carbon fabric reinforced pps [PDF]

open access: yes, 2012
This study assesses the use of infrared welding for a carbon fabric reinforced polyphenylene sulphide. Infrared light is used in order to melt the thermoplastic matrix of the two components, after which they are joined together under pressure.

Capacitive Pixelated CMOS Electronic Nose

open access: yesAdvanced Electronic Materials, EarlyView.
A 1024‐pixel CMOS capacitive E‐nose with inkjet‐printed MOFs and polymer layers yields gas‐specific capacitance fingerprints under humid conditions, discriminating toluene from 2‐butanone at low power. ABSTRACT Although some of the human senses can nowadays be replaced by low‐cost electronic sensors such as microphones and image sensors, a compact low ...
