The Near-Infrared Extinction Law in Regions of High Av

open access: yes, 2005
We present a spectroscopic study of the shape of the dust-extinction law between 1.0 and 2.2um towards a set of nine ultracompact HII regions with Av > 15 mag.

Tumor‐Targeted Exosome‐Based Heavy Atom‐Free Nanosensitizers With Long‐Lived Excited States for Safe and Effective Sono‐Photodynamic Therapy of Solid Tumors

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered exosome‐based heavy atom‐free nanosensitizers are developed for safe and targeted sono‐photodynamic therapy of solid tumors. The IR820‐TPE‐loaded, biotin‐conjugated exosomes (IR820‐TPE@B‐Exo) demonstrate significant promise for NIR fluorescence imaging‐guided sono‐photodynamic cancer therapy.

Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted

Acid/Base‐Responsive Circularly Polarized Luminescence Emitters with Configurationally Stable Nitrogen Stereogenic Centers

open access: yesAdvanced Materials, EarlyView.
Circularly Polarized Luminescence (CPL) emitters based on Tröger's base analogues bearing two peripheral fluorophores (anthracene, pyrene or 9,9‐dimethylfluorene) are prepared following a straightforward and versatile synthetic approach from common precursors.

Continuous state branching processes in random environment: The Brownian case [PDF]

open access: yes, 2016
We consider continuous state branching processes that are perturbed by a Brownian motion. These processes are constructed as the unique strong solution of a stochastic differential equation.

Lifting the Dusty Veil II: A Large-Scale Study of the Galactic Infrared Extinction Law

open access: yes, 2009
We combine near-infrared (2MASS) and mid-infrared (Spitzer-IRAC) photometry to characterize the IR extinction law (1.2-8 microns) over nearly 150 degrees of contiguous Milky Way midplane longitude.

Magnetically Controlled Reversible Photomagnetic Nanoactuators for Dynamic Contrast Enhancement in Optical Coherence Tomography

open access: yesAdvanced Materials, EarlyView.
Photomagnetic nanoactuators with ≈90% scattering efficiency in the second near‐infrared window are demonstrated to exhibit magnetic field‐controlled modulation of optical scattering and optical coherence tomography signals. These nanoactuators are reversibly assembled and disassembled under the external magnetic field modulation, enabling enhanced ...

Halide Perovskite Photocatalysts for Clean Fuel Production and Organic Synthesis: Opportunities and Challenges

open access: yesAdvanced Materials, EarlyView.
This review provides the state‐of‐the‐art overview of halide perovskite‐based photocatalysts for hydrogen production from water and halogen acid solutions, CO2 reduction into value‐added chemicals, and organic chemical transformations. Different types of halide perovskite photocatalysts and their relative efficiencies for hydrogen generation and CO2 ...
