Axons of retinal ganglion cells are insulted in the optic nerve early in DBA/2J glaucoma

Journal of Cell Biology, 2007
Here, we use a mouse model (DBA/2J) to readdress the location of insult(s) to retinal ganglion cells (RGCs) in glaucoma. We localize an early sign of axon damage to an astrocyte-rich region of the optic nerve just posterior to the retina, analogous to ...

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Synthesis of Conjugated Linear and Cyclic Polyynes by Selective Alkyne Metathesis

Angewandte Chemie, EarlyView.
The formation of polyynes with an odd number of conjugated triple bonds is challenging, particularly for complex architectures since most established methods rely on irreversible C–C bond‐forming reactions. To address this, we have developed the synthesis of triynes via alkyne metathesis.

Evaluation of Noise Level in Intensive Care Units of Hospitals and Noise Mitigation Strategies, Case Study: Democratic Republic of Congo

Buildings, 2023
High noise levels in hospitals can affect patients’ well-being, staff productivity, and medical error rates. This study measured noise in two intensive care units (ICUs) in the Democratic Republic of Congo (DRC).

Degradable Donor‐Acceptor Polymeric Mixed Ionic‐Electronic Conductors for Transient Electronics

Advanced Materials Technologies, EarlyView.
Here, we report degradable donor–acceptor (D–A) polymeric mixed ionic‐electronic conductors for transient electronics. We take a systematic side chain engineering approach to elucidate how molecular‐level modifications of donor–acceptor (D–A) polymer structures can satisfy demands that are often conflicting: degradability, charge carrier transport, and

Tailoring Electronic Properties of Precision Graphene Nanoribbons via Nanopore Engineering

Angewandte Chemie, EarlyView.
Novel porous graphene nanoribbons incorporating [18]annulene nanopores, together with a nonporous GNR of identical width, have been synthesized. Spectroscopic and theoretical analyses reveal that nanopore incorporation effectively tunes their electronic properties by enlarging the bandgap, reducing charge‐carrier mobility, and modulating exciton ...

Deficiency of complement component 5 ameliorates glaucoma in DBA/2J mice

Journal of Neuroinflammation, 2013
BackgroundGlaucoma is an age-related neurodegenerative disorder involving the loss of retinal ganglion cells (RGCs), which results in blindness. Studies in animal models have shown that activation of inflammatory processes occurs early in the disease. In
