In this data article, we provide field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray spectroscopy (EDS) images of wet-spun polyurethane (PU)-silver nanoparticles (AgNPs)/graphene nanoplatelets (GNPs) composite fibers according to the content of AgNPs and GNPs. In addition, microstructural changes of PU-AgNPs/GNPs composite fibers due to heat treatment at various temperatures are provided. The data collected in this article is directly related to our research article "Stretchable and Electrically Conductive Polyurethane- Silver/Graphene composite fibers prepared by wet-spinning process" [1].

Objective: This in vitro study aims to evaluate the effect of placing polyethylene fibers used in large Class II MOD (mesio-occlusion-distal) cavities into different flowable resin composites and in different positions on the fracture resistance of the restoration.
Materials And Methods: Ninety healthy human molars were used in the study. No treatment was performed on 10 of these teeth and they were used as the control group.

Exploring new ecological and simultaneous processes to modify wood fibers (WF) by-products is a required pathway toward circular economy and sustainability. Thus, plasma-activated water (PAW) and ultrasound (U) were employed as alternative methods to modify WF in a continuous process. Such treatments promoted the etching and cavities on the WF surface that destabilized the hydrogen bonds of the hemicellulose and lignin molecules, increasing the cellulose fraction.

As batteries drive the transition to electrified transportation and energy systems, ensuring their quality, reliability, lifetime, and safety is crucial. While the solid electrolyte interphase (SEI) is known to govern these performance characteristics, its dynamic nature makes understanding its nucleation, growth, and composition an ambitious, yet elusive aspiration. This work employs chalcogenide fibres embedded in negative electrode materials for operando Infra-red Fibre-optic Evanescent Wave Spectroscopy (IR-FEWS), combined with Multivariate Curve Resolution by Alternating Least Squares (MCR-ALS) algorithms for spectra analysis.

Monitoring reactive nitrogen species (RNS) in complex biological media is essential for evaluating the health status of living organisms; however, biofouling on the sensor surface restricts its applications. To overcome this issue, we developed an antifouling electrochemical sensing platform using copper-platinum bimetallic nanoparticles/N-doped biomass porous carbon fibres (Cu-PtNPs/N-BCF) for directly detecting peroxynitrite anion (ONOO), a major type of RNS. Cyclic voltammetry measurements demonstrated that the Cu-PtNPs/N-BCF-2 nanocomposite, synthesised at a molar ratio of 1:1 between Co and Zn, exhibited exceptional electrocatalytic activity for ONOO oxidation.
