It is found that hydrogen makes a stronger covalent bond with the weaker hydride forming elements and hydride non-forming elements rather than the stronger hydride forming elements if there exist Ti atoms in the neighborhood in the alloyed TiH2.
It is found that hydrogen interacts more strongly with hydride non-forming elements, B, (e.g., Ni, Mn, Fe) than hydride forming elements, A, (e.g., La, Zr, Ti, Mg) in every hydrogen storage alloy, despite that there is a larger affinity of A element for hydrogen than B element in the binary metal-hydrogen system.

Therefore, the oxyanion forming elements such as Cr, As, and V are some of the most common trace contaminants in groundwater.
The role of oxide forming elements in stabilizing and widening the range of process parameters is emphasized.
However, lower recoveries for some hydride forming elements were observed, indicating element losses, possibly due to adsorption phenomenon.
Myelolipoma (myelo-, for marrow, lipo for fat and oma meaning tumor or mass) is a benign tumor-like lesion composed of mature adipose (fat) tissue and haematopoietic (blood-forming) elements in various proportions [ 6].
Surface elemental abundances of major rock-forming elements viz., Mg, Al, Si and Ca as well as Na derived from C1XS data corresponding to certain nearside regions of the Moon are reported here.
To eliminate this problem, gas-forming elements must be removed from the liquid before casting.
Curved mirrors, concave and convex, may be used in place of lenses as image-forming elements in reflecting telescopes.
When applied to permineralized fossils, this technique allows simultaneous mapping of organic material, major matrix-forming elements, and trace elements with microm-scale resolution.
