As a result, these graphene-pasted TiO2 spheres always display higher photocatalysis activity in both methylene orange dye degradation and 4-nitrophenol reduction than that of control graphene-TiO2 spheres in the case of the same usage of these carbon sheets, which indicates more efficient use of graphene sheets in these graphene-pasted samples in photocatalysis systems.
Therefore, in our search to develop a more efficient treatment with cell sheets, we are constructing 3D tissues by layering cell sheets.
"Now that capital is more scarce the banks have to be even more efficient in their balance-sheet and capital usage to maximise profitability".
Apportioning blame for the financial crisis was not part of his remit,but he lays a large part of the blame at the door of shareholders for encouraging companies to take on debt: "Three years ago there was a lot of talk about making balance sheets more efficient, gearing up, stock buy backs.
Part of this is down to fashion; companies have been urged to return spare cash to shareholders and to make their balance-sheets more efficient by taking advantage of the tax deductibility of interest payments.Another big boost to the market has been the broadening of its base beyond America.
There is no longer much of an advantage in being rated AAA: shareholders instead want companies either to return the spare cash that might help earn them a high rating or to make their balance-sheets more "efficient" by borrowing more to take advantage of the tax deductibility of interest payments, thus jeopardising an exalted status.Instead, most bonds are lumped together in the middle.
Cartilage formation was more efficient with 10 μm-thick sheets than with 30 μm sheets.
The results indicate that the systems with fin and thin metal sheet (TMS) are more efficient than other studied systems from the energy and exergy efficiency standpoints.
But none did.Cheap and liquid financing has enabled companies to make more efficient use of their balance sheets, potentially boosting returns to shareholders and allowing managers to concentrate on profits and cashflow.
The number of companies with safe AAA credit ratings has collapsed as more have acted on the theory that a debt-laden balance-sheet is more efficient (because interest payments are tax-deductible in most countries).The recent crisis has also diminished belief in the judgment of the financial markets.
