A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

where E is the total energy of the system, i, j and k denote the atoms, rij is the distance between pairs adjoining atoms i and j, Vij is the bonding energy, bij is an empirical bond-order term, Vatt ...

Transverse Waves: In transverse waves, the oscillations of the medium's particles are perpendicular to the direction of wave propagation. Examples include waves on a string and electromagnetic ...

While the VR6 might have a "V" in its name and two angled cylinder banks, it has much more in common with an inline-six configuration than a V6. Look at the VR6's bank angle again — 10.6 or 15 ...

Transverse and longitudinal engines each have their place, and each has its fans. To say one is better than the other is a bit of a fallacy, as their applications are quite different.

In order to protect the safe operation of pipelines from actions of damage, pre-monitoring and positioning is an important technological means. Theoretical and experimental analysis showed the hitting ...

US images collection US images in transverse and longitudinal views of the TNs were acquired during the same US examination. Then the images were anonymized and randomly arranged for further analysis.

The adiabatic and intrinsic mode formalism for nonuniform propagation environments, developed and tested in a companion paper (ibid., vol.39, no.8, p.1130-36, 1991), is applied to continuously ...
