Coherent energy scale revealed by ultrafast dynamics of UX3 (X = Al, Sn, Ga) single crystals by Nair, Saritha K., Zhu, J. X., Sarrao, J. L., Taylor, Antoinette J., Chia, Elbert E. M.

“…For UGa3, our data are consistent with the formation of a spin density wave gap as evidenced from the quasidivergence of the relaxation time τ near the Néel temperature TN. For UAl3 and USn3, the relaxation dynamics shows a change from single-exponential to two-exponential behavior below a particular temperature, suggestive of coherence formation of the 5f electrons with the conduction band electrons. …”

Self-Assembly of Semiconducting Polymer Amphiphiles for In Vivo Photoacoustic Imaging by Xie, Chen, Zhen, Xu, Lei, Qunli, Ni, Ran, Pu, Kanyi

“…Despite the advantages of semiconducting polymer nanoparticles (SPNs) over other inorganic nanoparticles for photoacoustic (PA) imaging, their synthetic method is generally limited to nanoprecipitation, which is likely to cause the issue of nanoparticle dissociation. The synthesis of near-infrared (NIR) absorbing semiconducting polymer amphiphiles (SPAs) that can spontaneously self-assemble into homogeneous nanoparticles for in vivo PA imaging is reported. …”

“…Strong one-photon absorption and large two-photon absorption cross-sections were observed for both compounds in the near-infrared region. Our studies demonstrated that a slight structural modification could significantly change the ground state and the electronic, optical and magnetic properties of a pro-aromatic π-conjugated system, and finally lead to new materials with unique properties.…”

A coherent image source method for flat waveguides with locally reacting boundaries by Min, Hequn., Qiu, Xiaojun., Li, Ningrong.

“…The method starts from formulating sound reflections into integrals by plane wave expansion, and the inherent intractability in solving these integrals in such spaces is avoided by introducing a physically plausible assumption that wave fronts remain the same before and after the reflection on a near-rigid boundary. By comparisons to the classical wave theory and the existing coherent ray-based methods, it is shown that the proposed method is considerably accurate to predict the sound propagation in flat waveguides with a sound absorbing ceiling and a reflective floor over a broad frequency range and for various source/receiver geometries, even if at large distances from the source compared to the waveguide height while the existing methods are shown to be erroneous.…”

Interface and surface cation stoichiometry modified by oxygen vacancies in epitaxial manganite films by Li, Zhi Peng, Bosman, Michel, Yang, Zhen, Ren, Peng, Wang, Lan, Zhu, Weiguang, Dong, Zhili, Foo, Yong Lim, Cao, Liang, Yu, Xiaojiang, Ke, Chang, Breese, Mark B. H., Rusydi, Andrivo

“…Here, transmission electron microscopy and synchrotron-based spectroscopy are used to demonstrate that oxygen vacancies during growth serve as a critical factor for modifying the cation stoichiometry in pulsed laser deposited La0.8Sr0.2MnO3 films. Near the film/substrate (SrTiO3) interface, A-site cations (La/Sr) are in excess when oxygen vacancies are induced during film growth, partially substituting Mn. …”
