Advanced Functional Materials, EarlyView.This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Advanced Functional Materials, EarlyView.The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

The significance of air pockets for modelling thermal errors of machine tools
, 2013 It is well known, especially with the prevalence of compensation for geometric errors, that thermal error represents the most significant proportion of the total volumetric error of the machine tool. Thermal error in machine tools originates from changes

Handling Ambient Temperature Changes in Characteristic Diagram Based Thermal Error Compensation
, 2022 S.131-138Thermal errors are one of the lead causes for positioning inaccuracies in modern machine tools. These errors are caused by various internal and external heat sources and sinks which shape the machine tool's temperature field and thus its ...

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 ...

Using the Spindle Cooling Temperature as a Tool for Compensating the Thermal Deformation of Machines
Acta Polytechnica, 2010 Thermal error compensation of machine tools is a relatively complex problem nowadays. Machine users have very high expectations, and it is necessary to use all means to improve the cutting accuracy of existing machines.
