Measurement of Optical Path Difference Based on Phase Modulation of Light Source for Meter-Scale and Kilometer-Scale Optical Fiber Interferometers

open access: yesIEEE Access
It is crucial in a wide range of applications based on optical fiber interferometry to precisely measure the length difference. In this article, a method of measuring the optical path difference between two arms of an optical fiber interferometer system ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Fiber-optic push-pull sensor systems [PDF]

open access: yes, 1992
Fiber-optic push-pull sensors are those which exploit the intrinsically differential nature of an interferometer with concommitant benefits in common-mode rejection of undesired effects.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

3D Multicellular Scaffold Based Model for Advancing Bone Disorder Research

open access: yesAdvanced Functional Materials, EarlyView.
A scalable 3D multicellular in vitro bone model engineered by integrating osteoblasts, osteoclasts, and endothelial cells on biodegradable scaffolds. The system recapitulates key features of human bone remodeling and disease pathology. As a proof of concept, the model mimics osteogenesis imperfecta, demonstrating its potential as a physiologically ...

High‐Concentration Mesogen‐Assisted Exfoliation of Low‐Dimensional Nanomaterials for Achieving Ultralow‐Temperature Actuations of Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Portable fiber optic coupled Doppler interferometer system for detonation and shock wave diagnostics [PDF]

open access: yes, 1993
Testing and analysis of shock wave characteristics such as detonators and ground shock propagation frequently require a method of measuring velocity and displacement of the surface of interest. One method of measurement is Doppler interferometry.
