如何有效规制技术巨头已然成为当前《反垄断法》修订的重要任务。技术力量虽然作为传统的市场支配地位认定要素,但长期以来呈现被虚置化的客观状态,致使技术巨头市场支配地位的认定难度增大,技术力量自身的传导效应被显著低估。数字技术对市场竞争的影响异于以往,其通过平台、数据、算法的数字市场三维结构框架影响生产与交易的全过程。技术与三维结构结合所形成的技术力量极为强大,超越了以控制价格为主的传统市场力量,结合社会与资本力量形成了更牢固的市场固化结构。在判断技术巨头的市场支配地位时,亟需发挥技术力量作为非价格型认定要素的重要作用。应当摒弃虚置技术力量作为市场支配地位认定要素的固有症结,提高技术力量在认定市场支配地位时所占权重,回归结构性视角,妥善防范技术巨头无序扩张。 相似文献

We have fabricated sub-quarter-micron-patterned Au templates with electron beam lithography, and studied their effect on the fluorescence intensity of immobilized, anti-rabbit IgG antibody labeled with AlexaFluor® 546. Varying the geometry of the structured surface, the plasmon resonances are tuned to match the fluorescence wavelengths and achieve significant fluorescence enhancement. Full electrodynamic simulations were used to understand the optical response and access the quality of the fabricated structures for surface plasmon excitation. 相似文献

Surface tension (γ) and viscosity (η) data of aqueous solutions of the deoxyadenosine (DOA) and the deoxyribose (DOR) sugars have been measured with the survismeter, a new instrument, along with tetrahydrofuran (THF), dimethylformamide (DMF), acetonitrile and dimethylsulphoxide (DMSO) solvents. The same properties have also been measured with a stalagmometer and a viscosimeter, respectively, which afford the same information, albeit at the expense of a larger amount of chemicals and solvents. We obtain comparatively better accuracy in both kinds of measurements than with conventional methods. Therefore, the survismeter lends itself as a simple and reliable instrument. 相似文献

Membrane technology is becoming more important for CO 2 separation from natural gas in the new era due to its process simplicity,relative ease of operation and control,compact,and easy to scale up as compared with conventional processes.Conventional processes such as absorption and adsorption for CO 2 separation from natural gas are generally more energy demanding and costly for both operation and maintenance.Polymeric membranes are the current commercial membranes used for CO 2 separation from natural gas.However,polymeric membranes possess drawbacks such as low permeability and selectivity,plasticization at high temperatures,as well as insufficient thermal and chemical stability.The shortcomings of commercial polymeric membranes have motivated researchers to opt for other alternatives,especially inorganic membranes due to their higher thermal stability,good chemical resistance to solvents,high mechanical strength and long lifetime.Surface modifications can be utilized in inorganic membranes to further enhance the selectivity,permeability or catalytic activities of the membrane.This paper is to provide a comprehensive review on gas separation,comparing membrane technology with other conventional methods of recovering CO 2 from natural gas,challenges of current commercial polymeric membranes and inorganic membranes for CO 2 removal and membrane surface modification for improved selectivity. 相似文献

The analysis of changes in the vibrational spectrum of infrared active molecules adsorbed on a ionic surface containing point or extended defects can be an efficient method to determine the nature and density of surface defects. We study the infrared response of ammonia molecules deposited on a ionic surface of MgO containing charge vacancies and dipolar defects in various concentrations and distributions and show significant changes assigned to the defects signature. A Monte Carlo approach is used to randomly deposit the probe molecules on the surface displaying random or regularly arranged defects at low temperature. 相似文献

Studies were performed to determine the chemical addition of a metal complex molecule, chlorotris(triphenylphosphine)iridium(I), on hydrogen passivated Si(1 1 1) surfaces to form a self-assembled monolayer (SAM). The iridium complex was synthesized prior to chemical addition, for which modified reaction conditions were chosen. Following addition, the silicon surfaces were characterized with X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry (CV). The XPS results revealed that the surfaces consisted of the expected elemental percentages and that the iridium has a slightly higher success rate at attaching to oxide-free surfaces. XPS data also strongly indicate that the iridium complex remained intact upon chemisorption and did not decompose during the addition reaction. CV data show a difference between iridium treated surfaces and control samples. Hydrogen passivated wafers with iridium complex were much more conductive than those which were terminated with just an oxide or with an oxide and iridium complex. Furthermore, no free iridium reagent was detected as an additional feature in the current profile, indicating there was no physisorbed layer. 相似文献
