We present a database of 21 bond dissociation energies for breaking metal-ligand bonds. The molecules in the metal-ligand bond energy database are AgH, CoH, CoO+, CoOH+, CrCH3+, CuOH2+, FeH, Fe(CO)5, FeO, FeS, LiCl, LiO, MgO, MnCH3NiCH2+, Ni(CO)4, RhC, VCO+, VO, and VS. We have also created databases of metal-ligand bond lengths and atomic ionization potentials. The molecules used for bond leng...

Fungal species Lasiodiplodia theobromae of family Botryosphaeriaceae is a pathogen causing significant loss production and quality mango crop in Vietnam worldwide. In this study, fungal strain designed as XB1 was isolated from stem-end rot fruits, identified tested its susceptibility to silver copper nanoparticles. Strain identification based on biological characteristics sequence analysis 5.8S...

Abstract Stability and structure of complexes between silver (I) l -methionine (L) deduced from potentiometric 1 H NMR measurements allow to assume the prevailing several protonated species. The experimental data are compatible with formation following complexes: AgL, AgL 2 , AgH L, L 3 4 . coordination sites obtained by spectra, showing that only bond methylthioether sulfur atom is responsible...

The work presents the design and fabrication procedures used to manufacture inexpensive iron-base powders employed as a matrix in diamond-impregnated tool components. Three newly developed low alloy steel powders, containing from 94.4 99.4 wt.% Fe, have been formulated with assistance of ThermoCalc software produced by means proprietary process patented AGH-UST. It has shown that are readily pr...

The yielding arch support is transported and installed in the face with use of auxiliary machines. These activities underground mining cause many problems, which have as yet not been solved. Currently, transport assembly are carried out manually, using roadheader suspended rail, or various types mounting platforms. analysis structure existing solutions resulted development an original that met ...

The world has a long experience of using harvested rainwater from rooftop catchments in urbanized regions. There are also many studies about the technical, health, and environmental details of such systems. The gradual prevalence of rainwater harvesting systems in the country exposes a necessity to determine and define some guidelines and instructions for health and environmental considerations...

Longwall shearers’ haulage system of the Eicotrack type, used most often nowadays, is presented in this article. Its disadvantages, causing problems with a correct operation mechanized longwall shearer systems, are discussed. The concept innovative Flextrack, which should reduce occurrence disadvantages mentioned above, described. A course and research results, connected rig tests Flextrack fun...

introduction: climate change is one of the most significant challenges in sustainable development that has negative effects on land and marine ecosystems. this phenomenon leads to imbalances that cause effects including hydrological changes, increased soil erosion, increased runoffs and reduced groundwater aquifer feeding, etc. effects of climate changes over the past decade have significantly ...
