Tailored Diketopyrrolopyrrole Derivatives for Efficient Deep‐Red Organic Lasers

open access: yesAdvanced Functional Materials, EarlyView.
Tailored diketopyrrolopyrrole derivatives exhibit high stable amplified spontaneous emission with single or dual bands. Incorporated into distributed‐feedback lasers based on one‐ and two‐dimensional dichromated‐gelatin diffractive gratings, these materials provide a robust, flexible platform for integrated organic deep‐red light sources. ABSTRACT Deep‐

Persistence of Photosensitivity [PDF]

open access: yesEpilepsia, 1997
Summary: Purpose: One hundred patients with photosensitive epilepsy were investigated as part of an ongoing follow‐up study. Average duration of follow‐up was 14 years; mean age at follow‐up was 27 years. Methods: All patients were EEG investigated using a standard technique of intermittent photic stimulation (IPS).

Tomographic Printing in a Chip: A Versatile Platform for Biomimetic 3D Organ‐on‐Chip

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel light‐based bioprinting approach, TVAM‐in‐a‐chip, enables rapid, contactless fabrication of biomimetic 3D organ‐on‐chip devices directly within preassembled microfluidic platforms. This strategy supports diverse materials, including cell‐laden resins, and eliminates post‐assembly steps.

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Photography’s Other Sensitivities

open access: yesMedia Theory
This article sets out to challenge the idea of photography as a medium that deals purely in the visible. Taking the example of the mid-twentieth-century British photography industry, this article considers photographic sensitivity as part of a sensory ...
