Assessing the Mechanism of NH3 Sensing in Flexible Carbon‐Nanotube‐Based Chemoresistive Sensors via In Situ Photoemission Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Flexible carbon nanotube chemoresistors detect NH3 through charge‐transfer interactions directly revealed by in situ synchrotron X‐ray photoelectron spectroscopy. Binding‐energy shifts of ≈1 eV correlate with resistance changes, demonstrating that intra‐CNT charge transfer between NH3 and CNTs is the dominant sensing mechanism.

Eco‐Friendly Schiff Base Cellulosic Adsorbent for Selective Removal of Cationic Dyes from Petroleum Wastewater: Synthesis, Characterization, and Application

open access: yesAdvanced Materials Interfaces, EarlyView.
The porous HMC selectively captures cationic dyes (MB and MG) from contaminated water, transforming dark, dye‐laden effluent into clean water. ABSTRACT Our investigation explores the exclusion of two health‐risk cationic dyes (e.g., Methylene Blue (MB) and Malachite Green (MG)) using a novel hydrazone‐modified cellulose (HMC) adsorbent synthesized via ...

Evaluation of the effectiveness of saponin biosurfactants in enhancing aqueous-plus-micellar phase solubility of naphthalene oily discharge component [PDF]

open access: yesActa Periodica Technologica
The micellar solubilization of naphthalene by the natural non-ionic surfactant saponin, obtained from Sapindus mukorossi, was assessed based on its micellar properties. The isolation and purification of saponin were conducted using the microwave-assisted

Interactional coherence in CMC

open access: yesProceedings of the 32nd Annual Hawaii International Conference on Systems Sciences. 1999. HICSS-32. Abstracts and CD-ROM of Full Papers, 2003
Text-only CMC has been claimed to be interactionally incoherent due to limitations imposed by messaging systems on turn-taking and reference, yet its popularity continues to grow. In an attempt to resolve this apparent paradox, this study evaluates the coherence of computer-mediated interaction by surveying research on cross-turn coherence. The results

Fabrication Method of Directional Microstructure for High Energy Density, High Power Battery Cathodes

open access: yesAdvanced Materials Interfaces, EarlyView.
Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...

CMC hierarchy

open access: yes, 2013
We propose an extension of the differential system for constant mean curvature (CMC) surfaces in a three dimensional space form to an associated hierarchy of evolution equations by the higher-order commuting symmetries. The infinite sequence of higher-order conservation laws of CMC surfaces admit the corresponding extension to the conservation laws of ...
