Kyuha Choi,Nataliya E. Yelina,Heïdi Serra,Ian R. Hendersone heat transfer is increasing very rapidly. This is mainly due to the weak absorption region in the near infrared (ir) which transmits more and more of the thermal radiation when the spectrum is shifted towards shorter wavelengths. The dominance of the radiative transport over conduction and convect

Wei Zhang,Joachim Messinges make them ideal candidates for window glazing materials. This paper describes recent progress in the two main steps in aerogel production: 1) the hydrolysis and condensation of silicon alkoxide to give alcogel, and 2) the removal of the alcohol from the alcogel to produce aerogel. These efforts a
