Magnetodielectric effect of Graphene-PVA Nanocomposites [PDF]

open access: yesJ.Phys. Chem. C, vol. 115 (29), 14285-14289, (2011), 2012
Graphene-Polyvinyl alcohol (PVA) nanocomposite films with thickness $120 \mu m$ were synthesized by solidification of PVA in a solution with dispersed graphene nanosheets. Electrical conductivity data were explained as arising due to hopping of carriers between localized states formed at the graphene-PVA interface.

On the transport of CO$_2$ through humidified facilitated transport membranes [PDF]

open access: yesarXiv, 2023
Membrane-based CO$_2$ removal from exhaust streams has recently gained much attention as a means of reducing emissions and limiting climate change. Novel membranes for CO$_2$ removal include so called facilitated transport membranes (FTMs), which offer very high selectivities for CO$_2$ while maintaining decent permeabilities. Recently, these FTMs have

Magnetism and Verwey transition in magnetite nanoparticles in thin polymer film [PDF]

open access: yesJournal of Alloys and Compounds, 569 (2013) 58-61, 2013
Magnetic and structural properties of magnetite nanoparticles stabilized in polyvinyl-alcohol thin films are investigated by using X-ray diffraction (XRD), transmission electron microscopy (TEM), electron paramagnetic resonance (EPR) and static magnetometry techniques. The nanoparticles have well-defined crystallinity, and are superparamagnetic at room

Selective Reduction Laser Sintering: A New Strategy for NO2 Gas Detection Based on In2O3 Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes selective reduction laser sintering (SRLS) to engineer In2O3 NPs for flexible NO2 sensors. The introduction of oxygen vacancy defects enhances sensor performance, offering excellent responsiveness, rapid response/recovery, superior selectivity, low detection limit, and long‐term stability.

Femtosecond pulse generation from a Topological Insulator mode-locked fiber laser [PDF]

open access: yesOptics Express (2014), 2014
We reported on the generation of femtosecond pulse in an anomalous-dispersion fiber ring laser by using a polyvinyl alcohol (PVA)-based Topological Insulator (TI), Bi2Se3 saturable absorber (SA). The PVA-TI composite has a low saturable optical intensity of 12 MW/cm2 and a modulation depth of ~3.9%. By incorporating the fabricated PVA-TISA into a fiber

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

open access: yesAdvanced Functional Materials, EarlyView.
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

Stratum Corneum‐Inspired Zwitterionic Hydrogels with Intrinsic Water Retention and Anti‐Freezing Properties for Intelligent Flexible Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A novel stratum corneum‐inspired zwitterionic hydrogel is developed for intelligent, flexible sensors, featuring intrinsic water retention and anti‐freezing properties. The quasi‐gel, composed of hygroscopic polymers and bound water, maintains its softness across a wide range of humidity.
