Summary: Despite extensive research, accurately predicting successful synthesis conditions for new pseudo-binary oxides remains a challenge. This study introduces a synthesis-condition recommender system to efficiently explore a wide chemistry space and successfully discovered two yet-to-be-found pseudo-binary oxides through systematic synthesis experiments.

Summary: A new molecular imprinted polymer based on magnetic graphene oxide nanoparticles (MGMIP) was synthesized by sol-gel procedure for the adsorption of creatinine. The distinguishing features of this study include the room temperature preparation of the polymer and the absence of an initiator. The maximum adsorption capacity of MGMIP was found to be 75 mg/g at pH 7, an initial creatinine concentration of 100 mg/l, and 20 minutes of adsorption time.

Summary: This study quantifies the contributions of adsorption, bioreduction, and desorption in EPS-mediated U(VI) immobilization. Experimental results show that U(VI) immobilization is faster when exposed to H-2 compared to O-2. The kinetic model reveals that adsorption is dominant in the first minute, bioreduction is dominant from the second minute to the 50th minute, and after 50 minutes, bioreduction is balanced by desorption. This study also provides the first set of equilibrium data for U(VI) adsorption by EPS alone and shows that U(VI) adsorption onto EPS is endothermic, spontaneous, and favorable at higher temperatures.

Summary: Controlling the orientation of fillers in nanocomposites at a nanometer scale can greatly improve their properties. This study used biaxially oriented PP (BOPP) as a template to control the growth and orientation of nanoparticles. Silicon alkoxide was impregnated in the amorphous space of BOPP using supercritical CO2-assisted impregnation, and the subsequent sol-gel reaction led to the formation of highly dispersed silica nanoparticles. The limited amorphous space in BOPP restricted the growth of particles and induced the formation of anisotropic particles. The synergistic contribution of anisotropic particles with preferential orientation and the crystalline orientation of the matrix dramatically enhanced the reinforcement.

Summary: The Sol-gel method was used to prepare a Si-Ti-epoxy organic-inorganic hybrid composite sol, which was cured on the carbon steel surface to form a transparent film with excellent electrochemical protection performance and hydrophobicity. The Si-Ti-epoxy hybrid film has a denser structure, higher impedance modulus, and lower corrosion current density compared to a double-thick epoxy film.

Summary: The study evaluated the potential of three different natural inorganic clays for removing malachite green dye from aqueous solutions. Results showed that Langmuir isotherm model and pseudo-first-order kinetic model best described the adsorption behavior of MG, and natural inorganic clays with higher surface area can be effective adsorbents for removing MG dye.

Summary: In this study, a molecularly imprinted polymer (MIP) was synthesized using quercetin as the template and characterized. The MIP showed high selectivity and specific recognition towards quercetin, with an adsorption capacity of above 90% after five regeneration cycles, indicating potential application for selective adsorption of quercetin.

Summary: Mesoporous thin films are widely used for their high surface area and efficient mass and charge transport properties. A two-step calcination process can reduce film contraction and enhance structural control, resulting in mesoporous films with higher porosity and larger pores. These films exhibit favorable characteristics for mass transport of large molecules.
