The energy transfer extent from the Ni2+ sensitizers to the Er3+ emitters and the back transfer from the Er3+ to the Ni2+ were studied to clarify the guide for efficient broadband-sensitive upconversion.
Besides the energy saving extent, the costs of energy saving measures as well as the environmental and social impacts are also necessary to be evaluated in order to make sure that the application of these measures can also meet sustainable development requirements.
Energy evaluation for the three strategies shows that they can save energy to some extent, and there is potential remained.
But they are unlikely to satisfy the world's thirst for energy to the extent their advocates assume.
Atomic energy, to the extent it replaces fossil fuels, also reduces greenhouse gas emissions and is a little less expensive than energy from fossil fuels, according to the government.
That includes emerging markets, that includes materials, industrials, consumer discretionary, technology and, to a lesser extent, energy.
High discharge energy increases the extent of surface damage and results in large size and overlapped craters on machined surface.
Among the cyclical stocks in the Dow are Alcoa aa, 3M mmm, DuPont dd, International Paper ip and, to a lesser extent, energy stocks such as Chevron chv.
However, gaseous and condensable products of the process must be demonstrated to allow for a recovery of energy to an extent that can make the process self-sustainable.
Second, this particle size effect is influenced by the remote effective strain, remote stress triaxiality and the interfacial energy to different extent.
