The Mojo Village mangrove forest in Pemalang has undergone environmental degradation due to land conversion into shrimp farming areas. This conversion has led to increased anthropogenic activities, which are potential sources of heavy metal contamination in the waters, particularly lead (Pb). This s...

solid state reaction technique (SSR) was used to prepare high-Tc phase in superconductors the effect of additional Pb to was investigated it has been found

Under the dual impetus of environmental regulations and reliability requirements, the Pb–free/Pb hybrid assembly process in aerospace-grade ball grid array (BGA) components has become an unavoidable industrial imperative. However, constrained process compatibility during single or multiple reflow pr...

We employed the dynamically constrained phase space coalescence model to study the X(3872), where the parton and hadron cascade model (PACIAE) was used to simulate Pb-Pb collisions at sNN=5.02 TeV in centralities of 0−10% and 30−50%. In this work, we examined the correlation between the yield of the...

The accumulation mechanism of Cd and Pb in raddish roots was studied. The results showed that in the first 12 hours the accumulation process of Pb in roots was probably due to rapid adsorption, later, to slow chemical precipitation and cell absorption. Especially, at high Pb content, chemical precip...
