Coral reefs are biodiverse ecosystems that rely on trophodynamic transfers from primary producers to consumers through the detrital pathway. The sponge loop hypothesis proposes that sponges consume dissolved organic carbon (DOC) and produce large qua

A critically important question that must be answered to understand how organic solar cells operate and should be improved is how the orientation of the donor and acceptor molecules at the interface influences exciton diffusion, exciton dissociation

A covalently linked multichromophoric array (BDP-Por) was used as the donor layer in planar heterojunction organic photovoltaic (OPV) cells with the structure ITO/BDP-Por/C60/BCP/Al (BCP = bathocuproine). BDP-Por is a platinum tetrabenzoporphyrin (Pt

A benzannulated boron dipyrromethene (BODIPY, bDIP) molecule exhibiting strong absorption at 640 nm was synthesized. The organic dye was used in an organic solar cell as the electron donor with C60 as the acceptor. The BODIPY dye demonstrated the bes

A series of bilayer films were prepared by vacuum deposition onto Silicon substrates. These films consisted of either Si/SiO2/donor/C60 or Si/SiO2/C60/donor, where the organic films were in the 20-40 nm thick range and the donors were 7,7-difluoro-14

The effects of sterics and molecular orientation on the open-circuit voltage and absorbance properties of charge-transfer states are explored in model bilayer organic photovoltaics. It is shown that the open-circuit voltage correlates linearly with t

SUMMARY We have studied viscous remanent magnetization (VRM) acquisition in lava clasts from volcaniclastic breccias from Ruapehu, North Island, New Zealand. The age of these deposits ranges from 2.5 to >65 ka BP VRM parallel to the direction of the

Constraining the process by which volcanoes become unstable is difficult. Several models have been proposed to explain the driving forces which cause volcanic edifices to catastrophically collapse. These include models for destabilisation of volcanic

Molecular orientation plays a significant role in determining the performance of small molecule solar cells. Key photovoltaic processes in these cells are strongly dependent on how the molecules are oriented in the active layer. We isolate contributi

Recent excavations at Alchester have shown that this Roman small town in Oxfordshire with its rectangular ground-plan had a military predecessor. It was preceded by one, possibly two, successive vexillation fortresses. Parts are buried deep beneath t
