Summary: This study investigated the electrochemical and electro-optical properties of four different dual electrochromic devices. Soluble donor-acceptor-donor (D-A-D) type conjugated electrochromic polymers based on didecyl substituted 3,4-propylenedioxythiophene and heterodiazole analogs were used in all devices and coated on ITO electrodes. The devices exhibited color changes from green to blue under applied external voltage, and their switching times, coloration efficiencies, and stabilities were evaluated.

Summary: In this study, a novel method for fabricating camouflage materials that can adaptively change color in the visible and infrared regions was reported. The materials were made by growing photopolymerizable liquid crystals onto highly aligned MXene nanostructured thin films. The resulting materials exhibited vivid structural colors and reversible switching between bright colored and dark black states under a low electric field. Pixelated devices that allow for pixel-controllable electrochromism were demonstrated, as well as a free-standing electrochromic flexible film that achieved visible electrochromism and thermal camouflage.

Summary: The high-performance electrochromic polyamide NPTB-PA shows multi-oxidation stages and lower oxidation potentials due to the strong electron-donating ability of dimethylamino groups. By forming covalent bonds between polymer backbones and precursor of zirconium dioxide via in-situ sol-gel reaction, the hybrid films could shorten the switching response time and reduce oxidation redox potentials. In the ECD, the combination of NPTB-PA and HV exhibits panchromatic absorption and extremely high contrast of transmittance change.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
