Selective adsorption of carboxymethyl cellulose over styrene-butadiene rubber on graphite in lithium-ion battery slurries revealed by small-angle neutron scattering

Published on 2026-08-21 by Takumi Kusano, Raka Firman Baskara Permana, Shin-ichi Takata, Satoshi Yamaguchi, Masashi Harada @NATURE

Abstract: Polymer Journal, Published online: 21 August 2026; doi:10.1038/s41428-026-01246-6Contrast-changed small-angle neutron scattering (SANS) was applied to directly investigate the adsorption behavior of styrene–butadiene rubber (SBR) and carboxymethyl cellulose (CMC) on graphite in lithium-ion battery slurries. While SBR showed negligible adsorption, CMC formed an adsorption layer on graphite, increasing the apparent surface fractal dimension. These results demonstrate that contrast-changed SANS p[...]


Our summary: Selective adsorption of carboxymethyl cellulose on graphite was studied using small-angle neutron scattering. Styrene-butadiene rubber exhibited negligible adsorption compared to carboxymethyl cellulose. The findings enhance understanding of polymer interactions in lithium-ion battery slurries.

Optimal sensor placement and online spatiotemporal modeling for parabolic distributed parameter system under sparse sensing

Published on 2026-05-28 by @OXFORD

Abstract: AbstractRestrictions on the number and placement of sensors are common in the modeling of parabolic distributed parameter systems (DPSs). Since the information from measurements is incomplete, developing an accurate approximation model and capturing their dynamic behavior for time-varying DPSs under sparse sensing is a challenge. In this paper, a novel online spatiotemporal modeling framework including data completion and optimal sensor placement is developed. Firstly, in the offline initializat[...]


Our summary: This paper presents a framework for optimal sensor placement and online spatiotemporal modeling of parabolic distributed parameter systems under sparse sensing. It includes an offline phase for learning spatial basis functions and a completion algorithm for reconstructing sparse data.
