Disulfide Glass: An Optical Polymer for Commodity Plastics, Precision Optics, and Photonics
From oil and glass refining to high performance commodity polymers with enhanced thermomechanical and optical properties—the synthesis of a new high refractive index, highly transparent optical thermoset polymer is reported, termed, disulfide glass that affords a robust optical glass amenable to fabrication of precision optics and thin film photonic ...

Epigenetics and cell death: DNA hypermethylation in programmed retinal cell death. [PDF]
BackgroundVertebrate genomes undergo epigenetic reprogramming during development and disease. Emerging evidence suggests that DNA methylation plays a key role in cell fate determination in the retina.

Laser Photocoagulation for Retinal Detachments and Retinal Tears in Cytomegalovirus Retinitis
Retinal detachment complicates the course of cytomegalovirus (CMV) retinitis in nearly 30% of human immunodeficiency virus-infected patients. The study goal was to evaluate laser photocoagulation in the treatment of CMV retinitis-related retinal detachments and retinal tears.Nonrandomized, observational cohort study.Sixty-three patients with CMV ...

Carbon Nanotube 3D Integrated Circuits: From Design to Applications
As Moore's law approaches its physical limits, carbon nanotube (CNT) 3D integrated circuits (ICs) emerge as a promising alternative due to the miniaturization, high mobility, and low power consumption. CNT 3D ICs in optoelectronics, memory, and monolithic ICs are reviewed while addressing challenges in fabrication, design, and integration.

A Homeostatic Photonic Device Integrating Vapor‐Regulated Thermo‐Optical Feedback Mechanisms
An inorganic homeostatic photonic device is designed to autonomously regulate light, temperature, and vapor sorption through integrated positive and negative feedback mechanisms at multiple wavelengths. The device uses a graded mesoporous 1D photonic crystal coupled with a photothermal layer.

Carotenoid Biosynthesis in Fusarium
Many fungi of the genus Fusarium stand out for the complexity of their secondary metabolism. Individual species may differ in their metabolic capacities, but they usually share the ability to synthesize carotenoids, a family of hydrophobic terpenoid ...
