Recently, with the tremendous development of crypto-currencies, distributed ledger technology (DLT) (e.g., blockchain) has attracted significant attention. The traditional Internet was originally design to handle exchange information. With DLT, we will have value. Although, DLT a great potential create new foundations for our economic and social systems, existing number drawbacks scalability) that prevent it from being used as generic platform across globe. In this paper, present novel...
This work presents a hybrid quantification model for LIBS.
Moderate cylindrical cavity was used to regularize the laser-induced plasma for signal strength enhancement and precision improvement in breakdown spectroscopy (LIBS). A polytetrafluoroethylene (PTFE) plate of 1.5 mm thickness with diameter 3 fabricated. It placed closely on a sample surface laser pulse shot through center hole sample. Using coal as samples, it verified that configuration both enhanced spectral line intensity reduced shot-to-shot fluctuation, showing its great potential...
In our previous work, we found that there was great potential to improve the pulse-to-pulse signal repeatability using a moderate cylindrical cavity confinement. However, improvement achieved only with certain experimental parameters; while under other conditions, no or even worse repeatability. present configuration redesigned and unexpected uncertainty from variation of laser alignment ablated aerosols were avoided. With these two improvements, demonstrated can always increase addition,...
Spark discharge has been proved to be an effective way enhance the LIBS signal while moderate cylindrical confinement is able increase repeatability with limited enhancement effects. In present work, these two methods were combined together not only improve pulse-to-pulse but also simultaneously and significantly as well SNR. Plasma images showed that stabilized morphology of plasma, especially for assisted process, which explained improvement repeatability.
Measurement of coal carbon content using laser-induced breakdown spectroscopy (LIBS) is limited by its low precision and accuracy. A modified spectrum standardization method was proposed to achieve both reproducible accurate results for the quantitative analysis in LIBS. The used molecular emissions diatomic (C 2 ) cyanide (CN) compensate diminution atomic high volatile samples caused matrix effect. compensated line intensities were further converted into an assumed standard state with...
The perturbed-chain statistical associating fluid theory and density-gradient are used to construct an equation of state (EOS) applicable for the phase behaviors carbon dioxide aqueous solutions. With molecular parameters influence respectively regressed from bulk properties surface tensions pure fluids as input, both interfacial solutions satisfactorily correlated by adjusting binary interaction parameter (kij). Our results show that constructed EOS is able describe in a wide temperature...
There is an ongoing debate regarding the potential of secondhand exposure non-users to various chemicals from use e-vapor products (EVPs). Room air levels 34 (nicotine, propylene glycol (PG), glycerol, 15 carbonyl chemicals, 12 volatile organic (VOCs), and four selected trace elements) were measured where EVPs cigarettes used by n = 37 healthy adult tobacco users in chamber. The MarkTen® 2.5% Classic (Group I), a Prototype GreenSmoke® 2.4% II), Ego-T® Tank with subjects' own e-liquids III)...

Its research focuses on forming mechanism distribution model geological factors controlling development, control to oil gas production, rule dynamic evolution during characterization modeling technology. Important has been made theory technology in high water-cut reservoirs, low...
Foam ceramics were prepared by using 80 wt.% sand shale, 8 coal fly ash, steel slag and 4 magnesite as raw materials 0.3 SiC foam agent. Effects of firing temperature holding time on performance phases investigated. Grey system theory was used to explore the correlation between pore structure parameters thermal conductivity. The sintered at 1160 °C for 50 min exhibit optimal comprehensive properties: bulk density 0.651 g/cm3, flexural strength 4.75 MPa, total porosity 73.58%, closed 54.16%,...
A procedure for the economic optimization of hydrothermal power systems operation has been developed. The is suitable on‐line system utilization on a daily basis. To alleviate inherent high dimensionality problem, time decomposition used. weekly and cyclic nature load demand makes it convenient to specify operational periods in terms weeks, days, hours. set three models, i.e., monthly (four weeks), daily, hourly, individual models are coupled perform an overall optimization. feedback...
