“…Generally, both nitro compounds and organic dyes are strongly dissolved in water and thereby they can severely pollute the environment to cause health issues to living things . Especially, 4‐nitrophenol (4‐NP) is an important hazardous pollutant in wastewater from industrial and agricultural sources . Similarly, eosin yellow (EY) dye is one of the important organic pigments and often used in several kinds of industries including food, paint, plastic, and textile .…”

and textile. [2,7] It can be readily bound to biomolecules and consequently used as a strain to tissue and cells. [8] However, the application of abnormal level of EY becomes toxic and unfriendly to both the environment and living things. The development of reduction/degradation of nitro compound and dye is thus much needed to convert these materials into harmless products. For instance, the 4-NP and EY could be catalytically reduced into the formation of 4-aminophenol and reduced form of EY, respectively, and believe that this process could become potentially an effective way to treat 4-NP and EY in polluted water. Accordingly, the design and development of proficient catalyst are a significant task for the catalytic reduction of 4-NP and EY with aspects of the efficient and fast process. The nanomaterial-based catalysts are enormously developed for their superior catalytic performance in the reduction of pollutants. [9][10][11][12][13] In general, metal nanoparticles are usually adopted for the catalysis application; especially palladium nanoparticles (Pd NPs) exhibited excellent catalytic activities. [14][15][16] Such metal nanoparticles play a vital role in the catalytic reduction showing effective performance compared to other bare nanomaterials. In order to further improve their catalytic activity, the metal nanoparticles were incorporated with diverse nanomaterials including carbon-based materials, transition metal dichalcogenides (TMD), and porous organic cages. [17][18][19][20][21][22][23][24][25] Compared to other fluorescent nanomaterials, the C-dots can be easily synthesized from different kind of sources including organic molecules, biowastes, proteins, amino acids, and so on. [26][27][28][29][30][31][32] Moreover, the surface of C-dots can be modified with several capping agents to improve their fluorescence properties according to the applications. [33][34][35][36][37] That's why the C-dots have been extensively utilized in the fields of chemo-and biosensors, and optoelectronic applications. Thus far, the C-dots are much less utilized in the catalysis as in the sensing application. By taking advantage of C-dots and Pd NPs, this work aims to develop a superior multifunctional nanohybrid in the multiple applications including chemical sensor and catalysis.With this intention, we have synthesized carbon-dots to encapsulate palladium nanoparticles (Pd/C-dots) by the photochemical method. Prior to the synthesis of Pd/C-dots, Palladium nanoparticles encapsulated in the carbon dots (Pd/C-dots) are demonstrated to play a role of multifunctional nanohybrid in the synergetic applications of sensor and catalysis. The photochemical method is applied to synthesize Pd/C-dots in which Pd nanoparticles (NPs) are dispersedly encapsulated by C-dots layer. The nanohybrid can function as a fluorescent sensor and reductive catalyst, due to the inherent properties of C-dots and Pd NPs, respectively. The Pd/C-dots exhibit a highly selective and sensitive detection toward the nickel (Ni 2+ ) ion with a detection limit of ...

“…Generally, the router sets a maximum value for the queue in this algorithm. When the queue length reaches the threshold, the next packets are dropped indiscriminately until the queue length returns to the threshold [7]. With the increase in network traffic and the development of network architecture, passive queue management problems of full queues, slow storage deadlocks, and global synchronization are becoming more common [8].…”

The phenomenon “bufferbloat” occurs when the buffers of the network intermediary nodes fill up, causing long queuing delays. This has a significant negative impact on the quality of service of network applications, particularly those that are sensitive to time delay. Many active queue management (AQM) algorithms have been proposed to overcome this problem. Those AQMs attempt to maintain minimal queuing delays and good throughput by purposefully dropping packets at network intermediary nodes. However, the existing AQM algorithms mostly drop packets randomly based on a certain metric such as queue length or queuing delay, which fails to achieve fine-grained differentiation of data streams. In this paper, we propose a fine-grained sketch-based proportional integral queue management algorithm S-PIE, which uses an additional measurement structure Sketch for packet frequency share judgment based on the existing PIE algorithm for the fine-grained differentiation between data streams and adjust the drop policy for a differentiated packet drop. Experimental results on the NS-3 simulation platform show that the S-PIE algorithm achieves lower average queue length and RTT and higher fairness than PIE, RED, and CoDel algorithms while maintaining a similar throughput performance, maintaining network availability and stability, and improving network quality of service.

“…The maximum EF is calculated to be 4.7 Â 10 7 at a MB concentration of 5 Â 10 À10 M, which is much higher than those of other Pd-based SERS substrates reported in the literature. [54][55][56][57] The SERS repeatability and uniformity induced by the Au@PdO x substrate were finally examined. We randomly tested 20 SERS spectral lines of MB (10 À5 M) on the Au@PdO x substrate, and the data are shown in Fig.…”
