2021930 · 1 Introduction. Halocarbons are among the larger drivers of anthropogenic climate change, ranking behind and and ahead of N 2 O for their direct radiative forcing (Naik et al., 2021; Thornhill et al., 2021).Here, direct radiative forcing only accounts for the heattrapping properties of these greenhouse gases, discounting any impacts on the radiation balance due to chemical or other feedbacks ...
201211 · Ozone is an allotrope of oxygen comprising three oxygen atoms arranged at an obtuse angle. It has a characteristic and distinctive odor that is detectable by humans at concentrations as low as ppm (Horváth et al., 1985).Ozone is generated naturally in the earth’s stratosphere by the action of shortwave ultraviolet (UV) light (< 240 nm) on molecular oxygen ().

200991 · Abstract. This study evaluated the ozone removal performance of moderatecost particle filters containing activated carbon when installed in a commercial building heating, ventilating, and air conditioning (HVAC) system. Filters containing 300 g of activated carbon per m2 of filter face area were installed in two ''experimental'' filter ...
2020715 · Semiconducting frameworks possessing porous structure are promising platforms for the detection of hazardous gas molecules. In this study, we propose a facile route to fabricate millimeterscale, threedimensional semiconducting SWCNT (sSWCNT) aerogels and demonstrate deactivation of the coexisting metallic SWCNT (mSWCNT) network via electrical breakdown process.
