Heavy metals have been accumulating in Brazilian soils, due to natural processes, such Previously Owned Chokes as atmospheric deposition, or human industrial activities.For certain heavy metals, when in high concentrations in the soil, there is no specific extractant to determine the availability of these elements in the soil.The objective of the p
Abstract Topological semimetals are three dimensional materials with symmetry-protected massless bulk excitations.As a special case, Weyl nodal-line semimetals are realized in materials having either no inversion superchargers or broken time-reversal symmetry and feature bulk nodal lines.The 111-family, including LaNiSi, LaPtSi and LaPtGe materials
