Linking science to technology: Using bibliographic references in patents to build linkage schemes 总被引:1,自引:0,他引:1

In this paper, we develop and discuss a method to design a linkage scheme that links the systems of science and technology
through the use of patent citation data. After conceptually embedding the linkage scheme in the current literature on science-technology
interactions and associations, the methodology and algorithms used to develop the linkage scheme are discussed in detail.
The method is subsequently tested on and applied to subsets of USPTO patents. The results point to highly skewed citation
distributions, enabling us to discern between those fields of technology that are highly science-interactive and those fields
where technology development is highly independent from the scientific literature base.

The optimal material removal strategy can improve a geometric accuracy and surface quality of thin-walled parts such as turbine blades and blisks in high-speed ball end milling.The dominant conception in the material removal represents the persistence of the workpiece cutting stiffness in operation to advance the machining accuracy and machining efficiency.On the basis of theoretical models of cutting stiffness and deformation,finite element method (FEM) is applied to calculate the virtual displacements of the thin-walled part under given virtual loads at the nodes of the discrete surface.With the reference of deformation distribution of the thin-walled part,the milling material removal strategy is optimized to make the best of bracing ability of still uncut material.This material removal method is summarized as the lower stiffness region removed firstly and the higher stiffness region removed next.Analytical and experimental results show the availability,which has been verified by the blade machining test in this work,for thin-walled parts to reduce cutting deformation and meliorate machining quality. 相似文献

Three-dimensional ordered thin films based on 12-phosphotungstic acid (PW12O40/SiO2) and lanthanide-substituted phosphotungstate (Eu(PW11O39)2/SiO2, Gd(PW11O39)2/SiO2 and Eu(P2W17O61)2/SiO2) were constructed by an inverse opal method, using polystyrene colloidal crystal as a template. The samples were characterized by elemental analysis, XRD, IR spectra, UV–vis diffuse reflectance spectra (DR-UV–Vis) and SEM techniques. These thin films show well-defined lamellar array with inverse opal structure, and lanthanide polyoxometalate thin films exhibit photoluminescent properties. 相似文献

A laboratory reactor was designed to test the effect of the interference instant of HY on the pyrolysis of pubescens. The time instant for intermediate species from pyrolysis to contact HY was controlled by varying the position of the catalyst bed relative to the pyrolytic cell. It was found that the effect of the interference instant was significant on the variation of different intermediate species, and the yield and quality of the products. The results also showed that, with the increase in the distance between the pyrolytic cell and the catalyst bed, the yield of liquid and relative content of the organics such as aldehyde, phenols, etc., decreased, while the yield of residue and relative content of acetic acid increased. The deoxygenation of the intermediate species was favored when the catalyst exerted its performance on them immediately after their formation. 相似文献

Sepsis, a life-threatening condition stemming from an uncontrolled host immune response to bacterial infections, continues to impose a significant global burden with high morbidity and mortality. Addressing the challenges posed by antimicrobial resistance and uncontrollable inflammation remains a challenge in sepsis treatment. Moreover, traditional antibacterial materials have low bacterial trapping efficiency and inevitable prolonged circulation within the bloodstream, resulting in suboptimal antibacterial effects, metabolic complications, and undesirable side effects. In this study, an innovative solution is introduced through the development of Fe3O4@SH@TBTCP-PMB, an aggregation-induced emission (AIE) photosensitizer (PS)-armored magnetic nanoparticles (NPs). It has high reactive oxygen species (ROS) generation efficiency and an exceptional ability to capture Gram-positive bacteria with over 80% enrichment efficiency within just 1 h, even at low bacterial concentrations. Under white light illumination, 100 µg mL−1 of Fe3O4@SH@TBTCP-PMB effectively eliminated more than 99.9% of methicillin-resistant Staphylococcus aureus (MRSA). Furthermore, its magnetic separation properties efficiently prevent systemic blood circulation and associated side effects. Most importantly, Fe3O4@SH@TBTCP-PMB demonstrates superior anti-inflammatory effects by regulating cytokines, reducing adhesion molecule expression, and managing oxidative stress levels. This multifunctional approach significantly enhances sepsis survival rates, offering a promising strategy for combating multidrug-resistant (MDR) bacterial infections in sepsis patients while addressing inflammation-related complications. 相似文献
