Summary: The aim of this study was to investigate the photocatalytic degradation of Acid Black 24 dye in a continuous flow cascade reactor using immobilized titanium dioxide on a cellulosic material. The results showed a synergistic effect of adsorption and photocatalysis, and various parameters affecting dye removal efficiency were examined. The best degradation yield was achieved in an acidic medium due to the strong attraction between the positively charged catalyst and the anionic dye molecules. The optimal times for achieving the best yields depended on the initial dye concentration, treated solution volume, and reactor feed rate. Additionally, the reuse of the catalytic material was technically feasible, which could reduce the cost of treatment for industrial-scale applications.

Summary: The study developed dual nickel photoredox catalysis conditions for the decarboxylative cross-coupling of aryl halides and carboxylic acids containing fully substituted α-carbons. High-throughput experimentation identified Ni(TMHD)(2) as the optimal precatalyst, while the nickel-bipyridyl complexes typically used in decarboxylative couplings predominantly produced undesired C-O products. Computational work provided insights into the potential mechanistic underpinnings for the C-C vs C-O selectivity of the nickel-diketonate complex.

Summary: The uptake of acetic acid on natural Gobi dust was investigated under different levels of relative humidity. Acetic acid was found to compete with water molecules for adsorption sites on Gobi dust, and its uptake decreased with increasing humidity. Interestingly, at high humidity levels, the uptake of acetic acid led to the formation of oxygenated volatile organic compounds. This study highlights the reactivity of acetic acid on natural mineral dust, and its potential contribution to atmospheric processes.

Summary: The article studies a helium plasma jet driven by 15-18 kHz sinusoidal voltage and its multi-periodic self-triggered mode or random mode based on applied voltage, driven frequency, and inter-electrode gap distance. Most of the observed bullets operate every 2 or 3 sinusoidal periods, resembling pulsed operating mode. The presence of an outer grounded electrode ring is crucial for ignition and enhances the propagation length up to 8 times. Fast imaging reveals pre-ignition self-triggered discharges and accumulation of charges beneath the ground electrode, locally enhancing the electric field. Bullet velocities are compared using optical emission spectrum for different polarities and gap distances.

Summary: In an attempt to produce alkenes efficiently, a photocatalytic process has been developed to selectively obtain ethylene from propionic acid degradation. Copper oxide-modified titanium dioxide nanoparticles were synthesized using laser pyrolysis, and the synthesis atmosphere strongly influenced the morphology and selectivity of the photocatalysts towards different hydrocarbons and H2 products. Under a helium environment, highly dispersed copper species in CuxOy/TiO2 promoted the production of C2H6 and H2, while under an argon environment, copper oxides organized into distinct nanoparticles favored the production of C2H4, with selectivity as high as 85% compared to 1% with pure TiO2.

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.
