Sub-10 fs Time-Resolved Vibronic Optical Microscopy.
Christoph Schnedermann, Jong Min Lim, Torsten Wende, Alex S Duarte, Limeng Ni, Qifei Gu, Aditya Sadhanala, Akshay Rao, Philipp Kukura
Aug 28, 2019
We introduce femtosecond wide-field transient absorption microscopy combining sub-10 fs pump and probe pulses covering the complete visible (500-650 nm) and near-infrared (650-950 nm) spectrum with diffraction-limited optical...
Femtosecond Transient Absorption Microscopy of Singlet Exciton Motion in Side-Chain Engineered Perylene-Diimide Thin Films.
Raj Pandya, Richard YS Chen, Qifei Gu, Jeffrey Gorman, Florian Auras, Jooyoung Sung, Richard Friend, Philipp Kukura, Christoph Schnedermann, Akshay Rao
Mar 10, 2020
We present a statistical analysis of femtosecond transient absorption microscopy applied to four different organic semiconductor thin films based on perylene-diimide (PDI). By achieving a temporal resolution of 12 fs with...
Revealing the Drag Instability in One-fluid Nonideal Magnetohydrodynamic Simulations of a 1D Isothermal C-shock
Abstract
C-type shocks are believed to be ubiquitous in turbulent molecular clouds thanks to ambipolar diffusion. We investigate whether the drag instability in 1D isothermal...
Photon upconversion through triplet exciton-mediated energy relay.
Sanyang Han, Zhigao Yi, Jiangbin Zhang, Qifei Gu, Liangliang Liang, Xian Qin, Jiahui Xu, Yiming Wu, Hui Xu, Akshay Rao, Xiaogang Liu

Lanthanide-doped inorganic nanoparticles turn molecular triplet excitons bright.
Sanyang Han, Renren Deng, Qifei Gu, Limeng Ni, Uyen Huynh, Jiangbin Zhang, Zhigao Yi, Baodan Zhao, Hiroyuki Tamura, Anton Pershin, Hui Xu, Zhiyuan Huang, Shahab Ahmad, Mojtaba Abdi-Jalebi, Aditya Sadhanala, Ming Lee Tang, Artem Bakulin, David Beljonne, Xiaogang Liu, Akshay Rao

The generation, control and transfer of triplet excitons in molecular and hybrid systems is of great interest owing to their long lifetime and diffusion length in both solid-state and solution phase systems, and to their...
Digital twin of an urban-integrated hydroponic farm
Abstract This paper presents the development process of a digital twin of a unique hydroponic underground farm in London, Growing Underground (GU). Growing 12x more per unit area than traditional...
Location of low-frequency oscillation sources using improved D-S evidence theory
This paper presents a method for localizing oscillation sources based on data fusion Dempster–Shafer (D-S) evidence theory. This study is based on data of each bus from the system collected by phasor measurement units (PMUs)....

A Constitutive Stress–Strain Law for Metals with Sigmoidal Curves
A formulation is proposed for true stress–true strain relationships in the plastic regime that exhibit sigmoidal shapes, such as those of certain metastable austenitic stainless steels (MASS). It contains two terms, broadly...
Enhancing monolayer photoluminescence on optical micro/nanofibers for low-threshold lasing.
Feng Liao, Jiaxin Yu, Zhaoqi Gu, Zongyin Yang, Tawfique Hasan, Shuangyi Linghu, Jian Peng, Wei Fang, Songlin Zhuang, Min Gu, Fuxing Gu
Jan 06, 2020
Although monolayer transition metal dichalcogenides (TMDs) have direct bandgaps, the low room-temperature photoluminescence quantum yields (QYs), especially under high pump intensity, limit their practical applications. Here, we...
Trade-off between UoS charge and investment cost for new distribution network users
This letter investigates the situation that high use-of-system charge (UoSC) might appear for new network users and studies the potential of network investment to avoid the high charge. It proposes a method to strike the...
Long-run marginal cost pricing based on analytical method for revenue reconciliation
Incremental and marginal approaches are two different types of methods to price the use of networks. The major difference between them is in the way they evaluate the costs imposed by network users. The former calculates network...
Strategic obfuscation and consumer protection policy
This paper studies obfuscation decisions by firms. We show that more prominent firms are more likely to obfuscate. While prominent firms always choose maximum obfuscation, the obfuscation by less prominent firms depends on...
Putting on a tight leash and levelling playing field
The paper reports the results of an experiment where asymmetric sellers of a product can obfuscate the market. We show that policy measures may have unintended effects of increasing obfuscation incentives. We find that policies...
