Summary: In this paper, a simple microfluidic strategy is introduced for the controlled fabrication of monodisperse amphiphilic Janus microparticles. The strategy utilizes online UV curing and phase separation to produce the desired morphologies. The functionalization of the microparticles can also be easily achieved by introducing certain elements into the dispersed phase. The versatility and efficiency of this strategy make it highly applicable in various fields.

Summary: The use of surfactant in colloidal synthesis is known to control the size and shape of metallic nanoparticles, but its influence on the NP structure is not well understood. This study demonstrates that the surfactant can significantly modify the lattice parameter of crystalline particles. The lattice parameter expansion observed in NiPt nanoparticles covered by a mixture of oleylamine and oleic acid is not explained by crystal defects, twinning, oxidation, or atoms insertion.

Summary: Mn alloying in thermoelectrics has been a long-standing strategy to improve their figure-of-merit by optimizing electronic transport properties, but its contribution to suppressing thermal conductivity remains unclear. Studying the lattice complexity of Sn1.02-xMnxTe using aberration-corrected TEM/STEM revealed the unique crystallography evolution of Mn, which plays a critical role in reducing thermal conductivity with rational phonon scattering pathways. Understanding this mechanism can have implications for other thermoelectric systems.

Summary: In this study, we successfully developed a fluorinated alumina material with a superhydrophobic surface by grafting 1H,1H,2H,2H-perfluorodecyltriethoxysilane onto mesoporous alumina. The fluorinated alumina exhibited a high water contact angle of 163.00 degrees and had a smaller specific surface area and larger surface roughness compared to mesoporous alumina. The water contact angle initially increased and then decreased with the increase of the amount of fluorinated silane in the grafting reaction. The fluorinated alumina showed excellent performance in oil-water separation with high flux, great separation efficiency, and repeatability.

Summary: This study investigates the core-shell structures of BiFeO3-BaTiO3 mixed-oxide ceramics using conventional electron energy loss spectroscopy (EELS) and scanning precession electron diffraction (SPED) mapping. The results reveal the presence of a BaTiO3-rich pseudocubic shell, a BiFeO3-rich outer core, and an inner core with a different composition. These inner cores are non-polar and do not contribute to the ferroelectric properties.

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: A new approach for polymer functionalization of ordered mesoporous silicas (OMS) was demonstrated by cocondensation of silica precursor and a functional polymer, using a tailored amphiphilic copolymer as pore template. The novel strategy allows for incorporation of the functional polymer into the mesoporous silica, resulting in materials with high specific surface area and large pores, and acceptable CO2 adsorption capacity with selectivity towards CH4 and N2.

Summary: The integrity of the blood-brain barrier (BBB) is crucial for the health of the nervous system. In this study, we found that loading the compound probucol within mesoporous silica particles (MSP) can enhance its antioxidant effects, thereby protecting the function and integrity of brain endothelial cells. Through in vitro and in vivo experiments using zebrafish models, we demonstrated that probucol-loaded MSPs can significantly reduce cellular damage caused by oxidative stress and inflammation, and decrease the permeability of the BBB.

Summary: This study investigated the colloidal characteristics of submicron-sized zeolite NaA in mixed ethanol-water solvents. The effects of solvent mixing ratio and various additives on zeolite dispersion were studied. Zeolite NaA particles became unstable in solvent mixtures with a high ethanol-to-water ratio, and the destabilization was explained by the DLVO theory. Improved stabilization of zeolite NaA suspensions was achieved in ethanol-rich solvent mixtures using nonionic low molecular weight organic additives, particularly PEG-400.

Summary: A heterogenized alternative method using aminated silica and a Ru-MACHOTM catalyst was developed for CO2 precapture and subsequent hydrogenation to MeOH. The support for the Ru catalyst was commercial mesoporous silica modified with three different amino-silane monomers. TEM and solid-state NMR spectroscopy were used to study the composites before and after the catalytic reaction. The gas-solid heterogeneous system was probed with gas-phase infrared spectroscopy to quantify the resulting products, and high turnover number (TON) values were observed for samples aminated with secondary amines.

Summary: Mesoporous silica particles (MSPs) have shown potential in controlling obesity and diabetes by reducing the digestion of starch through adsorption of α-amylase. This study found that α-amylase incorporated into MSPs displayed higher activity and stability compared to the control. Biosorption of α-amylase onto MSPs was observed, and it was concluded that the reduced enzymatic activity was due to the large size of the starch probe. Further insights into the environment of α-amylase inside MSPs were provided by NMR experiments.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
