Tunnelling and Underground Space Technology, 2013
Abstract A section of the tunnel of Dongzhimen station on Beijing metro Airport Express closely under-passing the turn-back track tunnel in service through Dongzhimen station on Line 13 was constructed by a mining method, termed the ‘tunnel-column method’.

Photochemical & Photobiological Sciences, 2005
With available high resolution structures of PSII and a collection of reported redox midpoint potentials for most of the cofactors, it is possible to compare the expected electron tunneling rates with experimental rates to determine which electron transfer reactions are likely to reflect simply engineered electron tunneling, and which are more ...

Journal of the American Chemical Society, 2015
Matrix-isolation experiments near 3 K and state-of-the-art quantum chemical computations demonstrate that oxalic acid [1, (COOH)2] exhibits a sequential quantum mechanical tunneling phenomenon not previously observed. Intensities of numerous infrared (IR) bands were used to monitor the temporal evolution of the lowest-energy O-H rotamers (1cTc, 1cTt ...

TUNNELS - TUNNEL BORING MACHINES.
Proceedings of the Institution of Civil Engineers - Civil Engineering, 1994This paper begins by describing the requirements for the tunnelling machines used in the construction of the Channel Tunnel. Five machines were used, three on the marine tunnels and two on the land tunnels. The description is then developed, distinguishing between the types of machines working under the sea and those under land.

Tunneling Into Superconductors
Physical Review Letters, 1962The tunneling of electrons through a thin insulating layer between a normal and a superconducting metal is discussed. A previous derivation is examined to bring out the connection with the semiconductor model of a superconductor, and the quasi-particle excitations in normal and superconducting states are discussed.
