Summary: This study investigated the use of biochars derived from sugarcane bagasse as adsorbents for removing Mn(II) from aqueous solutions. The researchers found that pretreating the biomass with NaOH and using lower pyrolysis temperatures resulted in biochars with better adsorption performance. They identified the mechanisms of Mn(II) removal to be complexation between oxygenated groups and the metal, formation of MnO, and cation exchange. The biochar with the best adsorption performance achieved a removal efficiency of up to 65.8% for Mn(II) in real mining effluent. This research highlights the potential of using biochar for removing Mn in complex effluents and emphasizes the importance of studying these materials under real conditions.

Summary: Fourteen biochars from seven biomass sources were tested for their long-term Cd2+ removal efficiency. Insect frass, spent peat, and chicken manure-derived biochars showed potential as Cd2+ adsorbents. The pyrolysis temperature played a crucial role in optimizing Cd2+ removal by insect frass and spent peat-derived biochars. The Cd2+ removal by chicken manure biochars, on the other hand, was not affected by the pyrolysis temperature. The kinetics of Cd2+ removal over the course of ten days revealed that insect frass biochar (450 degrees C) showed a gradual increase from 36 to 75 % Cd2+ removal, while chicken manure and spent peat-derived biochar (450 degrees C) already exhibited higher Cd2+ removal (72 - 89 %) after day 1. These findings highlight the importance of considering the long-term Cd2+ removal effect of certain biochars in future soil-based experiments.

Summary: This study successfully prepared magnetic biochars by ball-milling biochar with Fe3O4 nanoparticles, which showed high efficiency in removing polystyrene nanoparticles (NPs) from water. The magnetic biochars synthesized at different pyrolysis temperatures exhibited improved removal capacity compared to pristine biochars. The best removal efficiency was achieved by MBC500 due to its larger specific surface area and abundant oxygen-containing functional groups. Mechanism analysis indicated that hydrophobicity, electrostatic attraction, H-bonding formation, and 7C-7C conjunction contributed to the adsorption process.

Summary: Using high-throughput infrared imaging and 2-D clinostat treatment, we demonstrate that apical hook formation can occur without gravity-induced root bending. This formation begins with de novo growth asymmetry at the apical part, which is largely independent of auxin biosynthesis, transport, and signaling. Additionally, functional cortical microtubule array is essential for the enlargement of hook curvature.

Summary: Supported alloy catalysts are important in heterogeneous catalytic processes, but the synthesis of supported alloy nanoparticles with consistent composition and size distribution is challenging. In this paper, a simple and effective method for preparing highly dispersed, homogeneously alloyed bimetallic nanoparticles on oxide supports is reported. The method involves the solid solution of metal cations in the oxide and the electrostatic adsorption of a secondary metal species onto the oxide surface, followed by reductive annealing to induce metal exsolution and homogeneous alloying on the oxide surface. The applicability and generality of this method are demonstrated using different oxides and base-noble metal pairs.
