A tunable refractive index matching medium for live imaging cells, tissues and model organisms

open access: yeseLife, 2017
In light microscopy, refractive index mismatches between media and sample cause spherical aberrations that often limit penetration depth and resolution.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Mode-Splitting for Refractive Index Sensing in Fluorescent Whispering Gallery Mode Microspheres with Broken Symmetry

open access: yesSensors, 2018
Whispering gallery mode (WGM) resonators have become increasingly diverse in terms of both architecture and applications, especially as refractometric sensors, allowing for unprecedented levels of sensitivity. However, like every refractometric sensor, a

Comments on the Refractive Index of Tin Sulphide Nano-crystalline Thin Films [PDF]

open access: yes, 2013
The refractive indices of nano-crystalline thin films of Tin (IV) Sulphide (SnS) were investigated here. The experimental data conformed well with the single oscillator model for refractive indices.

Flat lens without optical axis: Theory of imaging

open access: yes, 2005
We derive a general theory for imaging by a flat lens without optical axis. We show that the condition for imaging requires a material having elliptic dispersion relations with negative group refraction, equivalent to an effective anisotropic refractive ...

Studies of Relation Between Turbidity and Refractive Indeks of Bottled Water in The Area of Banda Aceh by Using Interferometer Murty Method

open access: yesJournal of Aceh Physics Society, 2012
Bottled water is clean water ready to drink quickly without cooking however, it is not all of the bottled water have a good quality. The quality of water can be observed from the optical properties of water, such as clarity and refractive index.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Refractive Index Sensing by Using Mechanically Induced Long-Period Grating

open access: yesIEEE Photonics Journal, 2012
In this paper, a refractive index sensor using a mechanically induced long-period grating is proposed and experimentally demonstrated. The sensing element is based on a composite optical waveguide, which is made of a single-mode fiber, a Teflon-cannula ...
