Catalytic hydrogenolysis of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) has become a hot topic in the bioenergy field in recent years. It remains a challenge to mediate the activation/hydrogenation/hydrogenolysis of C-O and C[double bond, length as m-dash]O bonds of HMF at high temperatures. Herein, bimetallic Ru-Co/AC catalysts were prepared by the "two-step" reduction method and were used to catalyze the hydrogenolysis of HMF to DMF.

The western population of the red-crowned crane in mainland China has been decreasing in the past few decades and wild population enhancement programmes have been launched in this country. First, 14 captive-bred red-crowned cranes were released into the core area of Yancheng National Nature Reserve for Rare Birds (YNNR), one of the most important wintering areas of this species, in 2013 (seven individuals) and 2015 (seven individuals) and then 8 more captive-bred cranes were released into YNNR from February 2022 to February 2023. We used satellite positioning and drone monitoring to study the status of released cranes.

Deep eutectic solvents (DESs) are considered one of the most promising biomass pretreatment reagents, and their research applications in woody fibrous biomass are increasing yearly. Inspired by the research related to wood bending, we explored the effects of different DES systems on the bending development of wood, and the results showed that the addition of anhydrous ferric trichloride to the DES system of lactic acid/choline chloride could enhance the treatment effect that increased the bendability and torsion resistance of ash wood. The anhydrous FeCl could act as an active site and provide acidic protons to improve the treatment efficiency of DES.

  • The Gini index is used to measure the inequality of leaf and fruit sizes in plants, employing the Lorenz curve to illustrate their cumulative distribution.
  • Previous research has mainly focused on two performance equations, PE-1 and GPE-1, that model these Lorenz curves, while a potential alternative, PE-2, has not been thoroughly analyzed.
  • The current study compares four performance equations, including generalized versions, and finds GPE-1 to have the best fit for the data, while PE-2 displays a better linear behavior, aiding in the assessment of plant organ size distribution inequality.

The overall photocatalytic CO reduction reaction presents an eco-friendly approach for generating high-value products, specifically ethanol. However, ethanol production still faces efficiency issues (typically formation rates <605 μmol g h). One significant challenge arises from the difficulty of continuously transporting CO to the catalyst surface, leading to inadequate gas reactant concentration at reactive sites.

The broad use of propargyl amines and tetrazoles in pharmaceutical applications presents a well-established challenge. Their synthesis relies heavily on catalysis, which, in turn, has been hindered by the scarcity of stable and practical catalysts. In response to this issue, we have developed an environmentally friendly and sustainable catalyst by infusing copper hydroxide into basil seed hydrogel (Cu(OH)-BSH), creating a 3D nanoreactor support structure.

The dyeing properties of twisted bamboo fiber bundles were studied by using the combination of three primary colors in M-type reactive dyes. The study found that the three dyes of red, yellow and blue have good color rendering in the actual dyeing process, and because the molecular structures of the three are similar, the chemical reactions during the fixation are the same, so the final dyeing rate results are similar, which were 29-32%. Compared with the undyed twisted bamboo fiber bundle, the mechanical properties of the three-color twisted bamboo fiber bundle also changed significantly, and the tensile strength increased by 13.

After the smooth cordgrass invaded coastal China, native birds started avoiding the green desert, and bird diversity declined. After many years, a few passerine birds began to enter and use smooth cordgrass, but only birds with a nonspecialised habitat. In this study, we found that a native reed-specific bird, the parrotbill flocked and sang in a smooth cordgrass habitat throughout the overwintering period near Sheyang Port in Yancheng, Jiangsu Province.
