Fast ion transport through ultrathin shells of metal sulfide hollow nanocolloids used for high-performance energy storage

Abstract

Metal sulfide (MS, nickel sulfide/copper sulfide) hollow spheres with hierarchical, ultrathin shell structures have been constructed by a facile method. The as-formed MS hollow structures are shown to be uniform in sizes with hierarchical ultrathin shells, which could facilitate the transport of electrolyte ions. Electrochemical evaluations of the as-fabricated MS based materials as supercapacitors electrodes having high large surface area (106–124 m2 g−1) and high specific capacitances (up to 1460 F g−1) with good cycling stability (up to 94% retention after 5000 cycles), showing their potential applications in the next-generation high-performance supercapacitors used for energy storage.

A therapeutic oxygen carrier isolated from Arenicola marina decreased P. gingivalis induced inflammation and tissue destruction

“…The P. gingivalis strain (ATCC 33277) was purchased from the ATCC and cultured as described previously 13 . Briefly, bacterial culture was performed under strict anaerobic conditions at 37 °C in brain–heart infusion medium (BHI) (Sigma) supplemented with hemin (5 μg/mL) and menadione (1 μg/mL).…”

“…In case of foreign aggression, EC forming the junctional epithelium, act as a physical barrier and are the first line of host defense owing to their ability to elicit an innate immune response 12 . P. gingivalis invasion of EC activates resident periodontal tissue cells which in turn affects cell proliferation, differentiation, and migration of precursor immune cells into the wound environment 13 – 15 . This induces production of various inflammatory and immune mediators, such as cytokines, chemokines and matrix metalloproteinases by periodontal cells, resulting in tissue destruction 16 .…”

Porphyromonas gingivalis, a Long-Range Pathogen: Systemic Impact and Therapeutic Implications

“…P. gingivalis deploys an extensive arsenal of virulence factors such as lipopolysaccharide, proteases, fimbriae and a CRISPR-Cas system [ 8 , 15 , 16 ]; enabling it to modulate the host immune response to promote its survival through cellular colonization and spreading [ 17 , 18 ]. During the initial phase of infection, this bacterium manipulates the immune system through inhibition of cytokines and chemokines secretion [ 19 , 20 ].…”

“…Furthermore, the ability of P. gingivalis to persist in the periodontal tissue after chemokine paralysis may depend to its ability to hijack the complement system, preventing its clearance from the oral cavity [ 11 , 23 , 24 ]. In addition to paralyzing the immune response, P. gingivalis also targets other periodontal cell types such as gingival epithelial cells, fibroblasts, periodontal ligament cells, and osseous cells, leading to the establishment of an inflammatory environment [ 17 , 18 , 25 , 26 , 27 ]. This hijacking of the host immune response hinders immune cell recruitment, allowing P. gingivalis to spread and colonize the periodontal pocket.…”

Analysis of structural, morphological and electrochemical on Ni (OH)2 Coated carbon sphere by Hydrothermal method

“…The modern development of society depended with vitality and predominant widespread electric-vehicle, electronic gadgets and well known hybrid electric vehicle demand for energy source can be supplied using an unavoidable source such as electrochemical energy storage and sources [1][2]. The emergency need for effective energy storage devices was lead to in a prevalent and high concerned research exertion into the electrochemical energy storage devices too named as supercapacitors, ultracapacitors and Electrochemical double layer capacitor (EDLC) [3].…”
