Energy and electron transferMultimer ModelNon-adiabatic electron transferPhotosystem IIReaction CentreSupermolecularA quantitative structure–function relationship for an enzyme should relate the coordinates of atoms in a protein structure to the rates, equilibria and activation energies of the catalysed ...
As a first rough picture of an electron tunnelling across the sequence of amino acids constituting a protein we can consider the electron of energy E_0 moving in a periodic sequence of square potential barriers of height V_0=0.74 eV and of width a = 4.5 \mathring{A}, the average ...
The repeatable dynamic auroral display that results from a magnetospheric substorm paints a picture of a sudden destabilisation in the nightside magnetosphere that rapidly encompasses a large area spanning many degrees of latitude and hours of local time4. The wide variation in magnetic field topologies...
Using the kinetic picture presented here, together with the available structural information on LH2, it is now possible to quantitatively evaluate prospective mechanisms of energy transfer from both the carotenoid S2 and S1 states to the Bchl-B800 and Bchl-B850 molecules. This work was supported by...
Telecom services play a vital role in the socio-economic development of a country. The number of people using these services is growing rapidly with furthe
picture of the chemicals sector, where the need for a transition from fossil fuels as source of energy and feedstocks is highlighted. We next discuss some of the attributes that make solar energy an attractive alternative for the sector. Here, we analyse the progress made in the generation of...

The Chinese government is publishing this white paper to present a full picture of China’s ideas, actions, and achievements in green development in the new era, and to share with the world its experience in this regard. 一、坚定不移走绿色发展之路 ...
The event rate, energy distribution and time-domain behaviour of repeating fast radio bursts (FRBs) contain essential information regarding their physical nature and central engine, which are as yet unknown1,2. As the first precisely localized source, FRB 121102 (refs. 3,4,5) has been extensiv...
volume of the effluent gas (oxygen) as a function of time during the catalytic decomposition of 1.5 M NaBrO3 aqueous solution (preheated to 60 °C) in the presence of the catalyst, using the water displacement method (Methods for details; a picture of the system is in Supplementary ...
