Circularly Polarized Perovskite Photodetector with Photocurrent Dissymmetry Factors of up to 1.95 Enabled by Liquid Crystal

open access: yesAdvanced Functional Materials, EarlyView.
Photodetectors made using perovskite single crystals in combination with free‐standing cholesteric liquid crystal (CLC) polymer films exhibit photocurrent dissymmetry factors up to 1.95 for 520 nm circularly polarized light (CPL) excitation. The CPL spectral response of the photodetector is tunable over a broad range of wavelengths by tuning the ...

Baffle system employing reflective surfaces [PDF]

open access: yes
Reflective baffles are proposed to reject off-axis light entering a telescope. Toroidal surfaces and adjacent cones are positioned so that off-axis rays make multiple reflections between these two surfaces.

Correlated mid-infrared and X-ray outbursts in black hole X-ray binaries: a new route to discovery in infrared surveys

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT The mid-infrared (MIR; $\lambda \simeq 3\!\!-\!\!10\ \mu \mathrm{ m}$) bands offer a unique window into understanding accretion and jet formation in Galactic black hole X-ray binaries (BHXRBs). Although difficult to observe from the ground, the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) survey offers an ...

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

open access: yesAdvanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

open access: yesAdvanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

open access: yesAdvanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and
