This shows that bigger temperature differences between day and night require thermal storage materials to play a better role in heat storage.
(2) In terms of thermal comfort, a good building envelope thermal storage performance ensures a better cooling effect for a night ventilated building, while larger temperature difference between day and night requires thermal storage material to play a better role in heat storage

At these small sizes materials behave distinctively, giving QDs unprecedented tunability and enabling never before seen applications to photovoltaic technology [1].
All the materials in the field of view, including the quartz, epoxy, the deposited Ge-rich SiO layer and the n-type Si layer, are amorphous and with different color contrast.
However, the wave crest for quartz substrate is so wide from around 200 cm-1 to 500 cm-1 due to the characteristics of amorphous materials.
