A number of environmental, agronomic and engineering applications require knowledge the Atterberg limits (liquid limit, LL; plastic PL) plasticity index, PI soils. The tedious costly nature standard experimental methods, as well challenges with measurement repeatability motivated development regressions more sophisticated techniques to estimate from other properties such clay content, cation ex...

In this short note we show that a system M=(E,r) with ground set E of size m and (rank) function r:2E→Z≥0 satisfying r(S)≤min(r(E),|S|) for every S⊆E, the Tutte polynomial TM(x,y)≔∑S⊆E(x−1)r(E)−r(S)(y−1)|S|−r(S),written as TM(x,y)=∑i,jtijxiyj, satisfies any integer h≥0, have ∑i=0h∑j=0h−ih−ij(−1)jtij=(−1)m−rh−rh−m,where r=r(E), use convention when h<m, binomial coefficient h−rh−m is interpreted ...

The DNA binding and inhibition of transcription in vitro by neutral Rh(2)(mu-O(2)CCH(3))(4) and cationic cis-[Rh(2)(mu-O(2)CCH(3))(2)(phen)(2)](2+) complexes were investigated. The binding constants of the two complexes to calf-thymus DNA were estimated from absorption titrations to be 4.6 x 10(2) M(-)(1) and 1.7 x 10(4) M(-)(1) for Rh(2)(mu-O(2)CCH(3))(4) and cis-[Rh(2)(mu-O(2)CCH(3))(2)(phen)...

The 2D atomic structure of h-BN would be an excellent dielectric layer to complement graphene electronics. When grown sequentially on metal substrates create GR/h-BN/metal sandwich structures, these nanomaterials can used in various applications. To this end, project we studied the adsorption and dissociation cyclohexene benzene clean covered Rh(111) surfaces at low high temperatures. Although ...

Hydrogenated amorphous silicon-germanium (aSiGe:H) films and n-i-p solar cells near the threshold of microcrystalline formation have been prepared by plasma enhanced chemical vapor deposition (PECVD) with a fixed germane to disilane ratio of 0.72 and a wide range of hydrogen dilution RH=(H2 flow)/(GeH4+Si2H6 flow) values of 1.7, 10, 30, 50, 120, 180 and 240. The effects of RH on the structural ...

In the title compound, [Rh(C(13)H(16)NO)(CO)(2)], a square-planar coordination geometry is observed around the Rh(I) atom, formed by the N and O atoms of the bidentate ligand and two C atoms from two carbonyl ligands. The Rh(I) atom is displaced from the plane through these surrounding atoms by 0.0085 (2) Å. The dihedral angle between the benzene ring and the N-C-C-C-O plane is 89.82 (6)°, and ...

We report on the observation of superconductivity in $\mathrm{La}{\mathrm{Rh}}_{2}{\mathrm{As}}_{2}$, which is analog without $f$ electrons heavy-fermion system with two superconducting phases $\mathrm{Ce}{\mathrm{Rh}}_{2}{\mathrm{As}}_{2}$ [S. Khim et al., Science 373, 1012 (2021)]. A zero-resistivity transition, a specific-heat jump, and drop magnetic ac susceptibility consistently point to t...

Reaction of a series of linked diimidazolium dibromide salts with one-half equivalent of [Rh(mu-OAc)(COD)](2) under reflux conditions generates a series of carbene-anchored/pendent-imidazolium complexes, [RhBr(COD)((R)C(H)-eta(1)-C(eth))][Br] ((Me)C(H)-eta(1)-C(eth) = ethylene[(N-methyl)imidazolium][(N-methyl)imidazole-2-ylidene] and (tBu)C(H)-eta(1)-C(eth) = ethylene[(N-tert-butyl)imidazolium]...

The partial oxidation of methane (POM) is a promising method for converting to syngas. transition metal supported on boron nitride (BN) has recently been studied as part catalog emerging catalysts. However, the chemical state BN during reforming still in debate. In this work, we report rhodium catalyst (Rh/BN) POM, with exceptional activity and long-term stability at 600 °C 230 h. Rh/BN was inv...
