The effect of bonding structure of diamond like carbon (DLC) film with surface nickel coating upon laser annealing by Xu, Naiyun, Tsang, Siu Hon, Tan, Chong Wei, Teo, Hang Tong, Wang, Xincai, Tay, Beng Kang

“…The Raman spectra shows more pronounced change for a-C films with Ni coating than those without Ni coating upon laser annealing, and the Raman features also suggest that the Ni surface coating can enhance formation of the six-ring graphitic-like sp2 ordering. Electrical measurement shows a low resistive characteristic for both set of films due to laser induced conducting sp2 clusters formation.…”

Transient prediction of nanoparticle-laden droplet drying patterns through dynamic mode decomposition by Tanis-Kanbur, Melike Begum, Kumtepeli, Volkan, Kanbur, Baris Burak, Ren, Junheng, Duan, Fei

“…The developed data-driven approach has also achieved the acceptable prediction for the droplet diameter with less than 0.13% error and a coffee-ring thickness over a range of 2.0 to 6.7 μm. Moreover, the proposed machine learning algorithm can recognize the volume of the droplet liquid and the transition of the drying regime from one to another according to the predicted contact line and the droplet height.…”

Controlling Cherenkov angles with resonance transition radiation by Lin, Xiao, Easo, Sajan, Shen, Yichen, Chen, Hongsheng, Zhang, Baile, Joannopoulos, John D., Soljačić, Marin, Kaminer, Ido

“…However, since the Cherenkov angle depends only on the material’s permittivity, the material unavoidably sets a fundamental limit to the momentum coverage and sensitivity of Cherenkov detectors. For example, ring-imaging Cherenkov detectors must employ materials transparent to the frequency of interest as well as possessing permittivities close to unity to identify particles in the multi-gigaelectronvolt range, and thus are often limited to large gas chambers. …”

Transient dynamics of a one-dimensional Holstein polaron under the influence of an external electric field by Huang, Zhongkai, Chen, Lipeng, Zhou, Nengji, Zhao, Yang

“…In particular, at variance with the case of an infinite linear chain, no steady state is found in a finite-sized ring within the anti-adiabatic regime. For strong diagonal coupling, the multi-math formula Anstaz is found to be highly accurate, and the phonon confinement gives rise to exciton localization and decay of the Bloch oscillations.…”
