The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
Vicinal dithioethers and alkenyl thioethers were synthesized under environmentally
friendly conditions using alkyne and thiol in water. Alkynes were also used to develop a
multibond-fonning reaction that fonned cyclic ketones or ketoesters through...
