Flexible Pressure Sensor With Multi‐Stage Microdome Structure Enabling Ultra‐Wide Linear Range and High Sensitivity for Wearable Applications

open access: yesAdvanced Science, EarlyView.
An MXene‐based flexible piezoresistive sensor featuring a multi‐stage microdome architecture is developed, which simultaneously realizes high sensitivity of 11.57 kPa−1 and an ultra‐broad detection range up to 2500 kPa. When integrated into palm and sole sensor arrays combined with deep learning algorithms, it achieves a recognition accuracy of over 95%

Cup marks on stones in Danish Bronze Age settlements

open access: yes, 2018
Amongst the variety of motifs in rock art cup marks are the most common and recurring of them all. In number, they appear alone or more commonly several together, even in hundreds and sometimes combined in motifs of linear or circular style and also appearing in combination with human or animal figures, ships and almost any other rock art motive.

Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

open access: yesAdvanced Science, EarlyView.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.
