TL;DR: A discovery algorithm of associated resources is first proposed to build original ALN for organizing loose Web resources and an application using C-ALN to organize Web services is presented, which shows that C- ALN is an effective and efficient tool for building semantic link on the resources of Web services.
Abstract: Association Link Network (ALN) aims to establish associated relations among various resources. By extending the hyperlink network World Wide Web to an association-rich network, ALN is able to effectively support Web intelligence activities such as Web browsing, Web knowledge discovery, and publishing, etc. Since existing methods for building semantic link on Web resources cannot effectively and automatically organize loose Web resources, effective Web intelligence activities are still challenging. In this paper, a discovery algorithm of associated resources is first proposed to build original ALN for organizing loose Web resources. Second, three schemas for constructing kernel ALN and connection-rich ALN (C-ALN) are developed gradually to optimize the organizing of Web resources. After that, properties of different types of ALN are discussed, which show that C-ALN has good performances to support Web intelligence activities. Moreover, an evaluation method is presented to verify the correctness of C-ALN for semantic link on documents. Finally, an application using C-ALN to organize Web services is presented, which shows that C-ALN is an effective and efficient tool for building semantic link on the resources of Web services.

TL;DR: In this paper, a three-dimensional graphene-based hierarchically porous carbon (3DGHPC) has been prepared by a dual-template strategy and explored as the electrode for capacitive deionization (CDI).
Abstract: A three-dimensional graphene-based hierarchically porous carbon (3DGHPC) has been prepared by a dual-template strategy and explored as the electrode for capacitive deionization (CDI). The texture analyses indicate that the incorporation of porous carbon into the three-dimensional graphene (3DG) has constructed a hierarchical pore network with a bimodal pore distribution. Compared to those of the 3DG (250.3 m2 g−1, 0.49 cm3 g−1), the 3DGHPC exhibits a higher specific surface area of 384.4 m2 g−1 and an improved pore volume of 0.73 cm3 g−1. The electrosorption behavior investigated by electrochemical techniques demonstrates that the 3DGHPC electrode displays superiority in specific capacitance and cyclability, as well as electrical conductivity. The CDI performance evaluated by batch mode experiments at a direct voltage of 1.2 V in a 25 mg L−1 NaCl aqueous solution reveals that the 3DGHPC electrode presents a higher electrosorptive capacity of 6.18 mg g−1 and an increased desalination efficiency of 88.96%. The enhanced deionization properties are deduced to arise from the improved specific surface area and increased pore volume, as well as an elevated electrical conductivity.

TL;DR: It is found that when a light beam travels through a slab of optically denser dielectric medium in air, the lateral shift of the transmitted beam can be negative, a novel phenomenon that is reversed in comparison with the geometrical optic prediction according to Snell's law of refraction.
Abstract: It is found that when a light beam travels through a slab of optically denser dielectric medium in air, the lateral shift of the transmitted beam can be negative. This is a novel phenomenon that is reversed in comparison with the geometrical optic prediction according to Snell's law of refraction. A Gaussian-shaped beam is analyzed in the paraxial approximation, and a comparison with numerical simulations is made. Finally, an explanation for the negativity of the lateral shift is suggested, in terms of the interaction of boundary effects of the slab's two interfaces with air.

TL;DR: In this paper, a novel sulfur-doped hierarchically porous carbon with both structural and compositional modification was proposed for persulfate (PS) activation by using thiophene as sulfur/carbon precursor and KOH as activator.
Abstract: Sulfate radicals (SO 4 − ) generated from persulfate (PS) activated by carbocatalysis is expected to provide an environmentally friendly and highly efficient catalytic oxidation process for aqueous organics degradation. Herein, a novel sulfur-doped hierarchically porous carbon with both structural and compositional modification was proposed for PS activation by using thiophene as sulfur/carbon precursor and KOH as activator. The effect of annealing temperature on its textural properties and surface chemistry was characterized by Elemental analysis, N 2 sorption isotherms, X-ray photoelectron spectroscopy, Fourier transform infrared spectra, Raman spectra and X-ray diffraction. The as-prepared sample treated at 800 °C (SDAC-800) demonstrated outstanding catalytic activity for activation of PS to degrade 4-chlorophenol (4CP). Studies on the role of sulfur in the catalytic activity enhancement were carried out by comparing with a sulfur-free activated carbon and a carbon model (reduced graphene oxide (rGO)). The effects of catalyst dosage, initial 4CP concentration, and reaction temperature on 4CP degradation were comprehensively investigated. In addition, contrast tests with other conventional PS activation methods, SDAC-800 reusability and its general applicability tests were also carried out. The mechanism of PS activation and 4CP oxidation was elucidated by using quenching tests with chloridion, l -histidine and ethanol as radical scavengers. It revealed that the conventional radical pathway was not a critical role in 4CP degradation. In contrast, the process was controlled by both particle-surface interaction and non-radical pathway, and the latter played a dominant role.
