This study outlines the quantitation and characterization of element oxide nanoparticles (Al2O3, and CeO2) commonly used in the nanoelectronics and semiconductor fabrication industry for the chemical-mechanical planarization (CMP) of semiconductor surfaces. CMP is a process of smoothing surfaces with the combination of chemical and mechanical forces in preparation for photolithography. The proc...

In this paper, the bioconvective flow in a porous square cavity containing oxytactic microorganism in the presence of chemical reaction is investigated. The bioconvection flow and heat transfer in porous media are formulated based on the Darcy model of Boussinesq approximation. The governing partial differential equations are solved using the Galerkin finite element method. The computational nu...

We present a new method of chemical quantification utilizing thermal analysis for the detection of relative humidity. By measuring the temperature change of a hydrophilically-modified temperature sensing element vs. a hydrophobically-modified reference element, the total heat from chemical interactions in the sensing element can be measured and used to calculate a change in relative humidity. W...

Here, we present a sub-μm multimodal approach to image essential elements in Caenorhabditis elegans. A combination of chemical imaging technologies reveals total metal concentration, chemical state and the protein to which an element is associated. This application of distinct yet complementary chemical imaging techniques provided unique insight into essential and trace elements at the subcellu...

Abstract Superheavy element research has been a strong pillar of the program at GSI Darmstadt since its foundation. Six new elements were discovered along with many isotopes. Initial results on chemical properties heaviest obtained that allowed for comparing their behavior lighter homologs and theoretical predictions. Main achievements past five decades superheavy are described an outlook into ...

Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
