Thin and Compact Versus Thick and Porous Fouling Layers in the Emulsion Polymerization of Acrylates and Vinyl Acetates Studied In Situ With a Quartz Crystal Microbalance (QCM)

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Building on a quartz crystal microbalance with dissipation monitoring (QCM‐D), fouling in emulsion polymerization was compared between acrylate dispersions stabilized with a mobile, anionic surfactant and dispersions of poly(vinyl acetate‐co‐vinyl neodecanoate), PVAc, stabilized with polyvinyl alcohol, PVOH.

A Sustainable and Low‐Cost Zn‐Lignosulfonate Redox Flow Battery

open access: yesBatteries &Supercaps, EarlyView.
A cost‐effective Zn/lignosulfonate (NaLS) hybrid flow battery using 20 kDa NaLS delivers 3.52 Ah L−1 at 30 mM, with an average discharge voltage of 1.01 V, outperforming smaller NaLS. This sustainable design leverages industrial and bio‐based lignosulfonates, cheaper size exclusion membrane, and abundant Zn for ecofriendly, scalable energy storage ...

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Engineered Bacterial Ligand From Streptococcus pneumoniae on Macroporous Resins for Selective Affinity Capture of Secretory IgA

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Secretory immunoglobulin A (sIgA) is a promising emerging biopharmaceutical candidate, but it currently lacks a standardized platform for purification. To address this, a novel affinity chromatography resin was developed by immobilizing protein variants of the Streptococcus pneumoniae surface protein, SpsA, as an affinity ligand.

A Crystallographic Shear Driven by Oxygen Insertion in (LuFeO3)nLuFe2O4

open access: yesChemistryEurope, EarlyView.
Layered structures (LuFeO3)nLuFe2O4 exhibit a common structural transformation upon oxygen uptake. Although the LuFeO3 units do not directly participate in oxygen insertion, these inactive layers nevertheless influence the temperature at which oxygen absorption occurs.

Simultaneous Construction of Hydrophobic Environment and Optimized Ion Channels in V2O5 for Zinc Ion Batteries

open access: yesCarbon Energy, EarlyView.
With the preinsertion of hexamethylenebisammonium (HMA2+), the thermodynamic stability of V2O5 is improved, and the kinetics of electrochemical reaction are enhanced, benefiting from the pillar effect, hydrophobicity, and electrostatic shielding of HMA2+.
