Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Single-Atomic-Ensemble Dual-Wavelength Optical Standard [PDF]

open access: yesarXiv
We demonstrate a dual wavelength optical frequency standard based on the dual optical transition modulation transfer spectroscopy (DOTMTS) between different quantum transitions of the rubidium D1 (795 nm) and D2 (780 nm) lines. In a single rubidium atomic ensemble, modulation frequency sidebands from the 780 nm pump beam are simultaneously transferred ...

Levy path integral approach to the solution of the fractional Schrödinger equation with infinite square well [PDF]

open access: yesarXiv, 2013
The solution to the fractional Schr\"odinger equation with infinite square well is obtained in this paper, by use of the L\'evy path integral approach. We obtain the even and odd parity wave functions of this problem, which are in accordance with those given by Laskin in [Chaos 10 (2000), 780--790].

Triplet State Suppression for Energy Loss Reduction in 20% Nonhalogenated Solvent Processed Binary Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Asymmetric small molecule acceptor with a methoxylated end group is produced here, whose oxygen vibration is found effective in suppressing triplet state formation, thereby minimizing non‐radiative energy loss for 20% efficiency in nonhalogenated solvent cast binary organic solar cells.

Synthesis and Photothermal Processing of Silicon‐Based Nanoconfined MXenes

open access: yesAdvanced Materials Interfaces, EarlyView.
Intercalation of titanium carbide (Ti3C2Tx) MXenes with aminopropyl terminated polydimethylsiloxane (amino‐PDMS) is demonstrated through ion‐exchange method followed by photonic curing (PC) using xenon flashlamp. The intercalation and PC result in enhanced interlayer spacing of Ti3C2Tx of 13.5 and 11 nm, respectively. Furthermore, conversion of PDMS to

Compact Kähler manifolds with positive orthogonal bisectional curvature [PDF]

open access: yesMath. Res. Lett., Vol. 24, no. 3, 767-780, 2017, 2017
In this short note, using Siu-Yau's method [14], we give a new proof that any n-dimensional compact Kahler manifold with positive orthogonal bisectional curvature must be biholomorphic to $\mathbb{P}^n$.
