Summary: In this study, Pd-doped TiO2 nanoparticles were proposed as a high-efficiency electrocatalyst for NH3 synthesis under ambient conditions. The catalyst exhibited high NH3 yield and faradaic efficiency, surpassing most recently reported Pd- and Ti-based electrocatalysts for N-2 reduction. Most importantly, it demonstrated extraordinary long-term electrochemical stability.

Summary: To achieve sustainable ammonia production, electrocatalysts with high selectivity, activity, and durability are needed for electrochemical nitrogen reduction reaction (NRR). However, the stability of N-N triple bond and the competition from hydrogen evolution reaction (HER) pose challenges in adsorbing and activating N2 on the surface of electrocatalysts, resulting in low ammonia yield and Faraday efficiency.

Summary: By introducing porous boron nitride into ionic liquids, the efficiency of sulfur extraction from fuel oil can be improved. Using m-BN-PIL as an extractant under optimized conditions achieves desulfurization performances of 59.2% and 61.8% for dibenzothiophene and 4-methyldibenzothiophene, respectively. After four stepwise extractions, the extraction efficiency over dibenzothiophene reaches 98.2%, achieving deep desulfurization of fuel oil.

Summary: Ammonia has a wide range of daily applications as an important chemical product and carbon-free energy carrier. While the industrial synthesis method using the Haber-Bosch process meets production demands, its huge energy consumption and gas emission limit development. Therefore, the clean and sustainable electrocatalytic N-2 reduction reaction has attracted attention, but the chemical inertness of N-2 molecules poses challenges. Recent progress in low-dimensional nanocatalyst development, electronic control aspects in NRR electrocatalysts, theoretical mechanisms, reaction pathways, challenges and future prospects are discussed.

Summary: In this study, six different bismuth molybdate catalysts were synthesized using a fast microwave-assisted hydro-thermal method. The morphology and structure of the synthesized catalysts can be modified by adjusting the pH in the preparation process. The sample prepared at pH 1, BMO-1, showed excellent activity for oxidizing sulfur compounds in fuel oil.

Summary: DNA fragmentation is a crucial step in genetic sequencing strategies, genetic research, and disease diagnosis. In this study, an acoustic microfluidic chip with ultrasound-actuated microbubbles was developed for efficient on-chip DNA fragmentation. The use of tensile forces generated by acoustic streaming near the oscillating bubble interfaces, as well as the synergistic effect of streaming stress and ultrasonic cavitation, allowed for fast and efficient DNA fragmentation. The bubble-enhanced effect was demonstrated to be more than three times faster than without bubbles, and the on-chip performance was comparable to a high-end commercial system. This new bubble-enhanced microfluidic approach shows promising potential for current and next generation sequencing platforms, and enables the implementation of full molecular protocols on a single microfluidic platform.

Summary: The electrochemical synthesis of cyclohexanone oxime from nitrite and cyclohexanone using a low-cost Cu-S catalyst under ambient conditions is reported. This strategy eliminates the need for complex procedures, noble metal catalysts, and the use of H2SO4/H2O2, while achieving comparable yield and selectivity to the industrial route. The study demonstrates a mild, economical, and sustainable approach for the alternative production of cyclohexanone oxime.
