Summary: Crude oil adhesion is a common problem in the petroleum industry, affecting production efficiency and maintenance costs. Developing antifouling materials and understanding the adhesion mechanism is important. This study constructed a superhydrophilic/underwater superoleophobic PAFC coating with excellent antifouling properties. The adhesion mechanism was investigated using atomic force microscopy (AFM) droplet probe technique. The results showed that the PAFC modification achieved the best effect at a molar ratio of 1:3 between phytic acid (PA) and FeCl3 (FC).

Summary: The study investigates the exchange and fractionation of oxygen isotopes in uranium oxides during industrial processing, providing a method to determine the geographical origin of materials. The results show that the exchange kinetics and fractionation factors are temperature- and species-dependent, and the incorporation of isotopes from water vapor or oxygen is influenced by humidity and atmospheric conditions.

Summary: This study deposited patterned coatings with a hybrid organic-inorganic nature on metallic substrates using a sol-gel bilayer through dewetting. Inspired by the exoskeleton of a desert beetle, the hybrid coatings consisted of hydrophilic silica droplets on a hydrophobic CH3-silica bottom layer. By altering the initial solution concentration, the patterned morphology and distribution of hydrophilic droplets could be modulated. The patterned coating showed higher efficiency in atmospheric water harvesting and maintained its structure after exposure to humid air.

Summary: Functionalization of metal-organic framework-808 (MOF-808) with 11 amino acids (AA) led to the synthesis of a series of MOF-808-AA structures. Among them, glycine- and DL-lysine-functionalized MOF-808 showed the highest CO2 uptake capacities under flue gas conditions. The presence of water was found to enhance CO2 capture performance, and the mechanism of CO2 capture was attributed to the formation of bicarbonate. Furthermore, the performance of MOF-808-Gly in simulated coal flue gas conditions was examined, demonstrating the possibility of capturing and releasing CO2 through vacuum swing adsorption.

Summary: The study investigates the friction and wear properties of composite Bi2S3-MoS2 soft coatings under different humidity levels. Suspensions with varying proportions of Bi2S3 and MoS2 were sprayed onto polished steel substrates to create lubricating coatings. The coatings underwent tribological tests in different humidity levels, and the formation of tribofilms was evaluated under dry conditions. The addition of Bi2S3 to MoS2 significantly improved the durability of the coatings at all humidity levels, with a maximum increase of 760%.

Summary: This study reports an effective synthetic strategy for fabricating millimeter-sized MOF/PVDF composite beads with different amounts of PVDF binders and postfunctionalization. The diamine-grafted bead exhibited superior long-term performance compared to the pristine MOF powder, which is attributed to the presence of hydrophobic PVDF polymer in the composite material. This work provides important guidance for developing stable and shaped MOFs for indoor CO2 removal.

Summary: The ferroelectric refrigeration technology based on electrocaloric effect is a promising environmental alternative to gas compression refrigeration. By studying the electrocaloric effect in NBT-ST-KNN ceramics, it was found that the addition of KNN enhances the relaxor behavior and lowers the depolarization temperature. The experiments showed that under an electric field of 40 kV/cm, the sample achieved a high temperature change peak of 0.88K at 60 degrees Celsius, while the sample near room temperature exhibited the optimal electrocaloric effect.

Summary: The study of piezocatalysis, particularly for environmental issues, has become an important topic in piezoelectric research. However, the reliance on nanofabrication poses challenges in investigating complex composition-designed materials for better performance and large-scale applications. In this work, a machine learning strategy is employed to efficiently explore the compositional space for ceramic powders with excellent piezoelectric response, aiming to improve piezocatalytic performance. (Ba0.95Ca0.05)(Ti0.9Sn0.1)O3 is selected as a promising candidate due to its relatively large piezoelectric coefficient d33 and fewer elements. The mechanically-ground ceramic powders exhibit excellent piezocatalytic activity, comparable to previously reported nanoparticles, highlighting their potential for large-scale applications.

Summary: Antiferroelectric (AFE) materials with large entropy change and coexistence of positive and negative electrocaloric effects have attracted considerable attention in electrocaloric refrigeration. However, the electric hysteresis behavior of AFEs introduces significant deviation in indirect electrocaloric characterization. This study discovers the deviation through direct isothermal heat flow measurements and quantitatively calculates the self-heating effect from the hysteresis area of P-E loops.

Summary: In this study, a self-actuating dual cooling cycle system was proposed, combining the positive and negative electrocaloric effects (ECE) and electrostrain (ES) in a 0.7 Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-30PT) single crystal. It was found that a suitable reverse electric field can generate negative ECE and ES simultaneously, enhancing the cooling capacity of the system.

Summary: The addition of CaTiO3 in lead-free ferroelectric ceramics creates a morphotropic phase boundary (MPB) region with the coexistence of rhombohedral and orthorhombic phases, enhancing the relaxor feature and improving the electrocaloric effect (ECE). The optimal ECE property is achieved in the ceramic with x = 0.10 in the MPB region, exhibiting a large adiabatic temperature change (ATmax) and a wide temperature span (Tspan). In the composition with more relaxor feature in the MPB region, such as x = 0.12, the ECE is relatively weak under low electric fields but shows a sharp increment under a sufficiently high electric field.

Summary: Field-induced phase transition in antiferroelectric materials can lead to giant electrocaloric responses with high potential for cooling applications. This study demonstrates that the memory behavior of the material increases the likelihood of observing an electrocaloric response under certain field conditions. The researchers also observed a two-step microstructure change during the field-off process, which resulted in an abnormal heat flow signal. Through analysis, they found that this kinetic behavior is attributed to the competition between ferroelectric order pinned by memory behavior and the thermally favored antiferroelectric state. The study deepens the understanding of phase transitions in ferroelectric systems.

Summary: This study proposes a modular reprogrammable 3D moisture-sensitive mechanical metamaterial that uses multi-material 3D-printed bi-material curved strips and cubic nodes. Depending on the geometrical parameters and spatial layouts, the metamaterials exhibit tunable coefficient of hygroscopic expansion from negative to positive. In addition to homogeneous deformation, complex 3D hygroscopic deformation modes including shear and twist can be achieved. The metamaterials are reprogrammable and all the deformation modes can be switched by modular disassembling and reassembling of the curved strips, similar to LEGO building blocks.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
