Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

open access: yesAdvanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

The Camel Corps Experiment

open access: yes, 2018
“Did you know there was a push to create a Camel Corps right before the beginning of the American Civil War?” This certainly seems like an interesting piece of trivia to share around the dinner table, but what was the Camel Corps and what insights can it

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

open access: yesAdvanced Science, EarlyView.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.

Development and implementation of an adaptive digital beamforming network for satellite communication systems [PDF]

open access: yes, 1991
The use of adaptive digital beamforming techniques has, until recently, been largely restricted to high performance military radar systems. Recent advances in digital technology, however, have enabled the design of single chip digital beamforming ...

TopCas: Topology‐Gated Cas12a via DNA‐RNA Chimeric Circular crRNA for Amplification‐Free Nucleic Acid Detection and Conditional Gene Editing

open access: yesAdvanced Science, EarlyView.
The TopCas platform utilizes an engineered DNA‐RNA chimeric circular crRNA to establish topology‐gated control over CRISPR‐Cas12a activity, enabling target‐triggered self‐catalytic amplification (preamplification‐free). This system seamlessly integrates highly sensitive molecular diagnostics with conditionally controlled gene editing, demonstrating ...
