Catalytic hydrothermal pyrolysis behaviors of oil shale under restrained conditions.

The effect of oil shale expansion and the addition of FeCl on its pyrolysis behavior was studied by hydrothermal pyrolysis experiments of cylindrical oil shale at 350 °C. The expansion of oil shale promotes the development of pores and fractures, which leads to the drastic pyrolysis of kerogen and the discharge of pyrolysis products. Besides, when the radial swelling increment of the oil shale is 33% of the free expansion, the pyrolysis reaction is basically guaranteed.

Genomic Sequencing and Characterization of Two Species from the Qinling Region: Insights into Evolutionary Dynamics and Secondary Metabolite Potential.

mushrooms, common bulk edible fungi, have considerable culinary and medicinal value. The Qinling region, represented by Zhashui County, is the main production area of mushrooms in China. In this study, two wild strains, M12 and M13, selected from the Qinling region for their desirable horticultural traits after domestication, were sequenced and characterized.

Reconfigurable, Transformable Soft Pneumatic Actuator with Tunable Three-Dimensional Deformations for Dexterous Soft Robotics Applications.

Numerous soft actuators based on pneumatic network (PneuNet) design have already been proposed and extensively employed across various soft robotics applications in recent years. Despite their widespread use, a common limitation of most existing designs is that their action is predetermined during the fabrication process, thereby restricting the ability to modify or alter their function during operation. To address this shortcoming, in this article the design of a Reconfigurable, Transformable Soft Pneumatic Actuator (RT-SPA) is proposed.

Chemical structures, biological activities, and biosynthetic analysis of secondary metabolites of the Diatrypaceae family: A comprehensive review.

The family Diatrypaceae is a less well-known group within the order Xylariales (Ascomycota). Initially, the focus on its metabolites was related to the pathogenicity of one of its members, . To date, a total of 254 natural products have been identified from Diatrypaceae strains.

The chemical structures, biosynthesis, and biological activities of secondary metabolites from the culinary-medicinal mushrooms of the genus Hericium: a review.

Fungal phytochemicals derived from higher fungi, particularly those from the culinary-medicinal genus Hericium, have gained significant attention in drug discovery and healthcare. This review aims to provide a comprehensive analysis of the chemical structures, biosynthetic pathways, biological activities, and pharmacological properties of monomeric compounds isolated from Hericium species. Over the past 34 years, 253 metabolites have been identified from various Hericium species, including cyathane diterpenes, alkaloids, benzofurans, chromenes, phenols, pyrones, steroids, and other miscellaneous compounds.

Experimental Investigation on Magnetic Abrasive Finishing for Internal Surfaces of Waveguides Produced by Selective Laser Melting.

To enhance the surface quality of metal 3D-printed components, magnetic abrasive finishing (MAF) technology was employed for post-processing polishing. Experimental investigation employing response surface methodology was conducted to explore the impact of processing gap, rotational speed of the magnetic field, auxiliary vibration, and magnetic abrasive particle (MAP) size on the quality enhancement of internal surfaces. A regression model correlating roughness with crucial process parameters was established, followed by parameter optimization.

Natural and engineered xylosyl products from microbial source.

Glycosylation is a prevalent post-modification found in natural products and has a significant impact on the structural diversity and activity variation of natural products. Glucosylation is the most common type of glycosylation, whereas xylosylation is relatively rare. Despite their unique chemical structures and beneficial activities, xylosylated natural products from microorganisms have received little attention.

Secondary Metabolites of Bird's Nest Fungi: Chemical Structures and Biological Activities.

Bird's nest fungi, a general term for species in the family Nidulariaceae, are named for their fruiting bodies that resemble bird's nests. Two of their members, (Schw.) de Toni.

Observation of the clinical efficacy of percutaneous reduction by leverage combined with intramedullary nail internal fixation in the treatment of irreducible femoral intertrochanteric fracture: a retrospective single-arm cohort study.

Background: There are few reports on the efficacy and safety of percutaneous lever reduction combined with intramedullary nailing in the treatment of irreducible functional intertrochanteric fracture. This study was designed to investigate the clinical effect of percutaneous reduction by leverage combined with intramedullary nail internal fixation in the treatment of irreducible femoral intertrochanteric fracture.

Methods: A total of 26 patients with irreducible femoral intertrochanteric fracture admitted to Qilu Hospital were included in this study, including 10 males and 16 females.

Percutaneous Cerclage Wiring Combined with Cephalomedullary Nailing for Irreducible Subtrochanteric Fractures.

Objective: To explore the surgical method, operation essentials and the clinical effect of the treatment of irreducible subtrochanteric femoral fractures by percutaneous cerclage wiring and Cephalomedullary nail.

Method: From February 2016 to October 2019, 17 cases of irreducible subtrochanteric femoral fractures (SFFs) treated via a minimally invasive wire system and intramedullary nail fixation were reviewed retrospectively. Ten male and seven female patients were involved.
