Summary: Using colloidal particles as models to understand processes on a smaller scale is a valuable approach. The paper focuses on particle-based surfactants and reports on numerous unexpected properties. By creating a Janus-type particle characterized by two types of orthogonal dipoles, the paper shows the ability to control interparticle interactions in a field and drastically change the system's properties. A highly unusual aggregation-dissolution-reaggregation sequence is discovered and it is found that the amphiphilic properties can be switched off using a magnetic field to break multiphase systems.

Summary: This article investigates the linear stability of a Newtonian ferrofluid system centered on a rigid wire in the presence of a surrounding ferrofluid with different magnetic susceptibility. The study analyzes the effect of an electric current running through the wire, generating a magnetic stress at the fluid interface. The article solves the linearized Navier-Stokes equations for three-dimensional disturbances and determines the growth rate of the disturbances analytically. The results provide numerical values for the growth rate at arbitrary Reynolds numbers and explicit expressions for both inviscid and Stokes regimes. The article also explores the linear instability of a ferrofluid with radially varying magnetic susceptibility centered on a rigid wire under the influence of a non-uniform azimuthal field. It is proven that the system is linearly unstable if there is a positive gradient of susceptibility in the fluid, and applying an axial field can stabilize disturbances in cases of continuous and discontinuous susceptibilities.

Summary: A highly dispersed Ni catalyst supported by mesoporous SiO2 nanospheres and promoted by alkaline MgO was synthesized and used as an active and stable catalyst for dry reforming of methane (DRM). The Ni/MgO-mSiO(2) catalyst showed superior performance compared to similar catalysts in literatures, with stable CH4 and CO2 conversions around 82% and 85% during 120 hours of DRM reaction. The promotion effect of MgO on the Ni catalyst was systematically studied and found to enhance the dispersion of active centers, inhibit sintering and deactivation of Ni, and facilitate the cracking of CH4, activation of CO2, and elimination of carbon deposits.

Summary: Photonic crystal patterns with angle-dependent colors are a promising anti-counterfeiting material. Delicate PC patterns can be fabricated by silkscreen printing of photo-curable SiO2/monomer PC inks on the substrate, followed by UV irradiation to fix the PC structures. The resulting PC marks show noticeable angle effects, uniform color distribution, and good mechanical and chemical stabilities. Different silk screen stencils are investigated to achieve the best color intensity and printing resolution. As a demonstration of their anti-counterfeiting functions, the PC patterns exhibit color changes and reversible switches under different angles.

Summary: This study reports a method of fabricating an electrically responsive photonic crystal (ERPC) in weak polar media. The ERPC shows good performance due to less screening of Coulombic interaction. By using aniline as a weak polar solvent, the ERPC is fabricated without any charge-controlling agent. The resulting SiO2/ANI ERPC exhibits a broad reflection wavelength tuning range (230 nm) and a low working potential (1.4 V), leading to improved stability and reversibility of the electrical tuning.
