Summary: Ammonia (NH3) is a promising alternative to hydrogen in the energy sector due to its carbon-free nature and high hydrogen content. However, current NH3 synthesis processes consume a significant amount of energy and contribute to CO2 emissions. To improve efficiency, new catalysts are needed for NH3 synthesis under milder conditions. In this study, we developed a Ru supported on perovskite catalyst using a ball-milling-assisted exsolution method. The catalyst showed tunable morphology and better resistance to deactivation mechanisms compared to the conventional impregnated catalyst.

Summary: A Ce(0.5)Pr(0.5)Ox soot combustion catalyst with both high activity and thermal stability has been developed by combining Ce(0.5)Pr(0.5)Ox nanoparticles and MS-macroporous structures. The hybrid catalyst showed a significant decrease in soot combustion temperature compared to the uncatalyzed reaction, and the thermal aging only slightly affected its performance. The Ce(0.5)Pr(0.5)Ox nanoparticles provided high activity, while the MS structure improved the contact between the catalyst and soot particles.

Summary: This study proposes a new method for synthesizing urea at ambient conditions, which improves the efficiency of the C-N coupling reaction by stabilizing the crucial intermediate through the insertion of oxygen vacancies. The existence of oxygen vacancy-mediated selective C-N coupling reaction is verified through in situ spectroscopy techniques. The introduction of oxygen vacancies transforms the common catalyst carrier into an efficient electrocatalyst, with a higher urea yield rate compared to partial noble-metal-based electrocatalysts.

Summary: Biomass reforming using solar energy allows for the production of green hydrogen. Current biomass photoreforming inefficiently produces hydrogen due to intermittent solar light and incomplete degradation of biomass C-C bonds. This study overcomes these issues by converting carbohydrates into liquid hydrogen carriers (LHCs) suitable for transportation. The LHCs are then fully decomposed, releasing only H2 and CO2. By prioritizing complete scission of carbohydrate C-C bonds, this process yields 44 g of H2 per kg of glucose. This work demonstrates the production and storage of hydrogen through the complete breakdown of biomass C-C bonds.

Summary: The spatial distribution of nanoparticles in fresh plants is important to discuss due to the potential inaccuracies caused by dehydration. This study utilized laser ablation inductively coupled plasma mass spectrometry with a cryogenic chamber to achieve the spatial distribution of elements in cucumber leaves. The results showed that Ce3+ has a higher negative effect on CeO2. This study is the first to achieve imaging of Ce in plants in a cryogenic chamber, which has significant implications for assessing nanoparticles in biological tissues.

Summary: In this study, the temperature dependence of the magnetic properties of ceria nanoparticles with cubic morphology was systematically investigated. Magnetization measurements and electron paramagnetic resonance (EPR) spectroscopy revealed both ferromagnetic and paramagnetic behavior in CeO2 nanoparticles. The temperature dependence of the broad line in EPR spectra indicated a magnetic transition at approximately 50 K, which was attributed to the condensation of surface oxygen and the extinction of oxygen vacancies. This result further confirmed the relationship between oxygen vacancies and ferromagnetic behavior in CeO2 nanoparticles.

Summary: Cerium oxide nanoparticles have potential benefits for reducing oxidative stress in biological systems. However, they can also be toxic to plants. This study evaluated the phytotoxicity and uptake of sub-3-nm ceria NPs in Daikon radish microgreens. The results showed that cerium was absorbed by the roots and transported to the stems and cotyledons, leading to stunted root growth. However, the distributions of macro- and micro-minerals in the microgreens were not significantly affected.

Summary: This paper introduces an environmentally friendly fabrication process for converting hemp fibers into biocomposites through a pectin-based crosslinking reaction. The water-based chemical approach utilizes pectin and lignin present in hemp fibers to crosslink and produce hemp fiber composites in one step. Compared to traditional processes, our green process uses water as the reaction solvent and operates at a mild temperature of 70°C, eliminating the need for petroleum-based organic solvents and high reaction temperatures. In addition, the study examines the effects of different mass ratios of pectin to hemp fiber and pH values on the compressive strength and bulk density of the hemp fiber composite materials, confirming the formation of ester bonds between pectin and lignin via transesterification.

Summary: The presence of oxygen vacancies on CeO2 surfaces significantly reduces the activation energy barrier for the formation of DMC. Different rate-limiting steps are identified for the reduced CeO2 and stoichiometric CeO2 surfaces in the DMC formation process. Successfully identifying the rate-limiting step and active CO2 species could provide atomic-level guidance for the direct synthesis of DMC from the greenhouse gas CO2 and methanol.
