In the context of new scaffolds obtained by photochemical reactions, Paternò-Büchi reactions between heteroaromatic, trifluoromethylphenyl ketone and electron rich alkenes to give oxetanes are described. A comprehensive study has then been carried out on reaction aromatic ketones with fluorinated alkenes. Depending substitution pattern at oxetane ring, a metathesis is described as minor side pr...

This paper aims to analysis the behavior of DC corona discharge in wire-to-plate electrostatic precipitators (ESP). Currentvoltage curves are particularly analyzed. Experimental results show that discharge current is strongly affected by the applied voltage. The proposed method of current identification is to use the method of least squares. Least squares problems that of into two categories: l...

Udara partikulat yang ada pada lingkungan sekitar dapat memasuki tubuh makhluk hidup lewat saluran pernapasan, sehingga menyebabkan iritasi fungsi pernapasan. Kondisi tersebut menuntut untuk memberi inovasi alat bisa menurunkan persentase peredaran polusi udara di sekitar. Sistem filter electrostatic precipitator (ESP) ini merupakan salah satu penerapan mendukung pengurangan dihasilkan oleh inc...

Although improving electrostatic precipitator (ESP) collection of fine particles (micron and submicron sizes) remains of interest, it is not yet clear whether the turbulent flow patterns caused by the presence of electric field and charge in ESPs advance or deteriorate fine particle precipitation process. In this paper, results of the laser flow visualization and Particle Image Velocimetry (PIV...

The isocyanide complexes cis-[MCl2(CNC6H4-4-X)2] (M = Pd; X Cl, Br; M Pt; Br) form isomorphous crystal structures exhibiting the Cl/Br and Pd/Pt exchanges featuring 1D chains upon crystallisation. Crystal packing is supported by C–X···X–C halogen bonds (HaBs), C–H···X–C hydrogen (HB), X···M semicoordination, C···C contacts between C atoms of aryl ligands. results DFT calculations topological an...

In addition to public health measures, including social distancing, masking, cleaning, surface disinfection, etc., ventilation and air filtration can be a key component of multi-pronged risk mitigation strategy against COVID-19 transmission indoors. Electrostatic precipitators (ESP) have already proved their high performance in fluid filtration, particularly industrial applications, control exh...

In this study, two different dust collectors, one based on an inertial separator and the other electrostatic precipitator (ESP), were developed in order to reduce brake wear particulate matter (PM) emissions. Additionally, collection efficiencies for particles (BWPs) of ESP evaluated according pad type. case separator, BWP low-metallic (LM) non-asbestos organic (NAO) pads similar, cut-off size ...

Nonstationary combustion conditions at municipal solid waste incineration (MSWI) plants cause increased crude gas concentrations of polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF), and other products of incomplete combustion (PIC). Such transient conditions occur, e.g., during and after start-up processes in MSWI plants. The start-up and shut-down processes of a M...

in present study, the density functional theory (dft-b3lyp) method with svp basis set was used for optimizing and studying the electronic structural properties of cis and trans isomers of bis-(5-nitro-2h-tetrazolato-n2) tetraammine cobalt (iii) perchlorate (bncp) as powerful explosives at 298.15 k temperature and 1 atmosphere pressure. and also, natural bond orbital (nbo) population analysis an...

The quality of atomistic simulations depends decisively on the accuracy of the underlying energy function (force field). Of particular importance for condensed-phase properties are nonbonded interactions, including the electrostatic and Lennard-Jones terms. Permanent atomic multipoles (MTPs) are an extension to common point-charge (PC) representations in atomistic simulations. MTPs are commonly...
