Advanced Functional Materials, EarlyView.This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

The Doping and Temperature Dependence of Optical Properties of Nd1-xTI03 [PDF]
, 2005 A well characterized titanate system, Nd1_xTi03, has been studied by temperature dependent reflectance spectroscopy between 50 and 40 000 cm-1 at three different doping levels, x = 0.019, 0.046, and 0.095, which yield a Matt-Hubbard insulator, a ...

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN
Advanced Functional Materials, EarlyView.Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

Introduction : Doping and Public Health
, 2016 The concept of “doping” is usually associated with sport, particularly elite sport. In fact, doping means the use of substances or methods that are banned in sport by the World Anti-Doping Agency (WADA) because of their potentially performance-enhancing ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...
