Laser‐Induced in situ Synthesis and Assembly of Nano‐Cotton TiO2 Humidity Sensors with High Sensitivity and Fast Response for Real‐Time Respiratory Monitoring by Zhichao Yu, Juqing Li, Qiurui Zhang, Pei Xiang, Jincheng Lei

“…The nano‐cotton TiO2 is in situ synthesized and assembled to the interdigitate electrodes of the sensor structure using the transmitted picosecond laser deposition. The as‐deposited TiO2 layers are in situ post‐annealed by a CO2 laser to optimize the crystallinity and phase compositions for humidity sensing. …”

Crystalline and amorphous structure selectivity of ignoble high-entropy alloy nanoparticles during laser ablation in organic liquids is set by pulse duration by Robert Stuckert, Felix Pohl, Oleg Prymak, Ulrich Schürmann, Christoph Rehbock, Lorenz Kienle, Stephan Barcikowski

“…Particle cores in all cases exhibit a homogeneous distribution of the metals Cr, Mn, Fe, Co, and Ni, while particle shells were found to vary between manganese-enriched oxide layers and thin graphitic carbon coatings. The discovery of the structure-directing mechanism allows one to select between crystalline or amorphous HEA NP products, simply by choice of the laser pulse duration in the same, well-scalable setup, giving access to colloidal particles that can be further downstream processed to heterogeneous catalysts or magnets. …”

Ab initio simulation of spin-charge qubits based on bilayer graphene-WSe2 quantum dots by Huaiyu Ge, Peter Koopmann, Filip Mrcarica, Otto T. P. Schmidt, Ilan Bouquet, Mauro Dossena, Mathieu Luisier, Jiang Cao

“…In both electron and hole quantum dots, we find a two orders of magnitude enhancement of SOC (1.8 meV) compared to intrinsic graphene, in the layer directly adjacent to WSe2. Time-dependent investigations of the quantum device reveal rapid qubit gate operation in the order of picoseconds. …”
