The critical current in a one-dimensional (1D) crossed-field gap is defined by the transition from cycloidal flow to near-Brillouin (nB) state characterized electron orthogonal both electric and magnetic fields uniform virtual cathode formation. Motivated recent studies on space-charge-limited non-magnetic diodes, we assess meaning of two-dimensional (2D) geometry. Particle-in-cell (PIC) simulations demonstrate that binary behavior between laminar turbulent does not occur 2D because...
In this study, an inexpensive catalyst (Fe–Zn/Al2O3) was investigated to efficiently convert alkaline lignin into phenolic monomers with formic acid at low temperatures. The successfully prepared by a co-impregnation method and showed high selectivity for production of monomers. With the optimal reaction condition, i.e., mass ratio 4:1 temperature 180 °C 6 h, highest yield bio-oil 28.31 wt % obtained as in situ hydrogen source presence Fe–Zn/Al2O3 catalyst. It indicated from composition...
In this study, montmorillonite (MMT) was used as an inorganic synergist to prepare the water-based intumescent flame retardant (IFR) ornamental coating for plywood. Results indicate that 7 wt.% MMT modified IFR (No. 3) possess best fire resistance (longer than 20 min) of tested samples according performance, which significantly declines specific extinction area by 44.12 m2·kg−1 compared without cone calorimeter. addition, characterizations such XPS, XRD, TG, SEM and FTIR were characterized...
While characterizing space-charge-limited current (SCLC) is important for numerous applications, no analytical solutions SCLC with monoenergetic initial velocity exist two-dimensional (2D) geometries. Here, we derive approximate closed-form uniform emission of electrons in a 2D planar diode, where restricted to long patch width W electrodes separated by distance D. We also semiempirical approach estimating the these cases treating geometric and correction factors as multiplicative...
An efficient, regioselective C-5 arylation of thiazolo[3,2-b]-1,2,4-triazoles catalyzed by a simple copper catalyst was developed. This proceeded smoothly and tolerated variety functional groups (44 examples). A wide range functionalized thiazolo[3,2-b]-1,2,4-triazole derivatives were obtained in high yields (up to 99% yield). Possible catalytic cycles the also discussed.
Prior studies have developed theories for the maximum permissible current, or critical one-dimensional planar and cylindrical crossed-field diodes where magnetic field is below Hull cutoff, meaning that an electron emitted from cathode reaches anode. Here, we develop semi-empirical analytical models to predict current a two-dimensional (2D) diode with nonzero monoenergetic initial velocity. The method considers geometry, velocity, as multiplicative corrections Child–Langmuir law space-charge...
New aromatic poly(ether ketone amide)s containing 4‐aryl‐2,6‐diphenylpyridine units were prepared by the heterogeneous palladium‐catalyzed carbonylative polymerization of diiodides with ether units, diamines bearing pyridine groups, and carbon monoxide. Polymerizations performed in N,N ‐dimethyl‐ acetamide (DMAc) at 120°C presence a magnetic nanoparticles‐supported bidentate phosphine palladium complex [Fe 3 O 4 @SiO 2 ‐2P‐PdCl ] as catalyst 1,8‐diazabicycle[5,4,0]‐7‐undecene (DBU) base...
The thermal decomposition of enzymatic hydrolysis lignin (EHL) was investigated by the thermogravimetric technique (TG/DTG) within temperature range from room to 920 °C at different heating rates (10, 20, 30, 40 and 50 °C/min).Little differences in mass losses as a function were observed TG analysis.It established that EHL pyrolysis consisted three main stages: water evaporation (<200 °C), devolatilization organic volatiles (200-500 °C) char formation (>500 °C).The evolved gases or Fourier...
Two monomers, 4,4′-bis(4-phenoxybenzoyl)biphenyl (BPOBBP) and 4,4′-diphenoxydiphenyl sulfone (DPODPS), were conveniently synthesized via simple synthetic procedures from readily available materials. A series of novel poly(aryl ether ketone)s containing both biphenylene moieties linkages in the main chain by modified electrophilic Friedel-Crafts acylation copolycondensation isophthaloyl chloride (IPC) with a mixture BPOBBP DPODPS, over wide range BPOBBP/DPODPS molar ratios. The resulting...
This study aimed to evaluate the preservative ability of modified flutriafol derivatives against decay fungi. The bacteriostatic effect on Trichoderma viride was not efficient as expected. Flutriafol a parent substrate improve its broad spectrum performance. Six triazole compounds were synthesized by Friedel–Crafts reaction, oxygen–sulfur–ylide and ring-opening addition reaction. structures target products determined 1H NMR MS. Antibacterial antileakage tests performed optimize most agents...
