Improving lithium-sulfur battery performance using a polysaccharide binder derived from red algae by Dóra Zalka, Alen Vizintin, Alexey Maximenko, Zoltán Pászti, Zoltán Dankházi, Kristóf Hegedüs, Lakshmi Shiva Shankar, Róbert Kun, Karel Saksl, Andrea Straková Fedorková, Pál Jóvári

“…Carrageenan-based electrodes deliver 30% higher capacity than those made with the industry-standard polyvinylidene fluoride binder. X-ray photoelectron spectroscopy analysis confirms the chemical binding of carrageenan to the sulfur active material, and transmission X-ray absorption spectroscopy reveals that carrageenan effectively traps shorter-chain lithium polysulfides, improving the overall battery performance.…”

Effects of underlying substrates on the underwater oleophobicity of graphene oxide-phytic acid (GO-PA) coatings by Sue Lyn Tan, Abraham Matthews Joshua, Ee Von Lau

“…Results showed that the underwater oleophobicity of GO-PA coated substrates was the lowest in stainless steel, followed by copper, polyvinylidene fluoride (PVDF) and carbon steel. The underwater oleophobicity was correlated to the increase in surface energy and surface roughness, accompanied by a reduction in the water de-wetting phenomenon at the contact region. …”
