Evaluation of the actinia-shaped composite coagulant for removal of algae in water: Role of charge density.

A series of novel cationic modified actinia-shaped composite coagulant (AMS-C), with similar tentacle length and distribution but different charge density (CD), was successfully designed and fabricated by combination of a cationic graft starch and attapulgite (ATP). AMS-C shows a high efficiency in coagulative removal of Microcystis aeruginosa from water over a wide pH range. The algae-harvesting efficiency of optimized AMS-C can reach to 92.

Microneedle (MN) sensors have great promise for food safety detection, but the rapid preparation of MNs for surface-enhanced Raman scattering (SERS) sensors with tunable and homogeneous nanoparticles remains a great challenge. To address this, a SERS sensor of gold nanoparticles@polydopamine@poly(methyl methacrylate) MN (AuNPs@PDA@PMMA-MN) was developed. The extended-Derjaguin-Landau-Verwey-Overbeek theory was applied to calculate the interaction energy between AuNPs and PDA.

In the integrated circuit manufacturing process, reverse osmosis (RO) membranes are widely used for wastewater reclamation. However, fouling by typical surfactants significantly reduces membrane efficiency and lifespan. This study investigates the fouling mechanisms of typical surfactants-cetyl trimethyl ammonium bromide (CTAB, cationic), sodium dodecyl sulfate (SDS, anionic), and polyoxyethylene octyl phenyl ether (TX, nonionic)-on RO membranes.

Topological magnetic skyrmions with helicity state degrees of freedom in centrosymmetric magnets possess great potential for advanced spintronics applications and quantum computing. Till date, the skyrmion study in this class of materials mostly remains focused to collinear ferromagnets with uniaxial magnetic anisotropy. Here, we present a combined theoretical and experimental study on the competing magnetic exchange-induced evolution of noncollinear magnetic ground states and its impact on the skyrmion formation in a series of centrosymmetric hexagonal noncollinear magnets, MnFeCoGe.

The breaking of inversion symmetry combined with spin-orbit coupling, can give rise to intrigu- ing quantum phases and collective excitations. Here, we report systematic temperature dependent Raman scattering and theoretical calculations of phonon modes across the inversion symmetry- breaking structural transitions in a quasi-one-dimensional compound (TaSe4)3I. Our investigation revealed the emergence of three additional Raman-active modes in Raman spectra of the low- temperature (LT) non-centrosymmetric (NC) structure of the material.
