cohesion–tension (C–T) theory has been proposed to explain water transport[8]. The C–T theory assumes that water, when confined in small tubes with wettable walls such as xylem elements, can sustain a tension ranging from 3 to 30MPa. The liquid forms a continuous system in the water-...
In the 3 × 3 matrix there are nine complex elements or 18 real parameters. However, the conditions that need to be satisfied by the rows and columns of a unitary matrix, as well as the requirement that the determinant of the matrix should be +1, reduce the number to eight independent ...
Atomic and close-to-atomic scale manufacturing provides a fundamental competence for the production of the fourth generation of core elements in contemporary industrialization. This review is organized based on atomic-level operation modes in subtractive, additive and transformative manufacturing processes....
The biennial review of atomic-weight determinations and other cognate data has resulted in changes for the standard atomic weights of 19 elements. The standard atomic weights of four elements have been revised based on recent determinations of isotopic abundances in natural terrestrial materials: cadmium...
first glimpse about seventy years ago,5,6NPCs have attracted increasing attentions from researchers. The NPC is the largest proteinaceous assembly in vivo, which consists of ~550–1000 molecules of ~30 different nucleoporins (Nups) with the molecular mass of 60–120 MDa from yeast to human, ...
Generally, BMGs have a constant (with respect to temperature) CTE, which is close to that of its main constituent elements10. Furthermore, it is interesting to note that crystalline alloys with the same bulk chemical composition as the Fe-based BMGs do not show the Invar effect, as ...

Atoms of an element are all the same in terms of shape and size and atoms of different elements differ in size and shape. Elements are characterised by mass of their atoms so all the atoms of an element have identical weight. Different elements have atoms of different atomic weight. Atoms ...
Motivated by the structure evolution experiments of Janus NiAu nanoparticles (NPs), we present a detailed study on the thermodynamic evolution of Ni and Au NPs with different ratios of Au and Ni through the molecular dynamics (MD) simulations. It is found that, for fixed Ni particle size (5.8...
first-principles calculation with no adjustable parameters, this agreement deserves particular attention. Similar results were obtained for8Be by the Green’s Function Monte Carlo (GFMC) calculation17,18, and for Be isotopes by the no-core CI calculation with the JISP16 interaction41. The three ...
