Three criteria for achieving high performing porous materials for water adsorption have been identified. These criteria deal with condensation pressure of water in the pores, uptake capacity, and recyclability and water stability of the material. Water ads ...
Energy demand and economic development are intrinsically linked. Earlier economic development came at the price of serious environmental pollution, posing a risk to life on earth. Thus, a transition from fossil to renewable energy is needed. Among the rene ...
Some nanoporous, crystalline materials possess dynamic constituents, for example, rotatable moieties. These moieties can undergo a conformation change in response to the adsorption of guest molecules, which qualitatively impacts adsorption behavior. We pos ...
Boron doped graphene oxide (B-GO) is a highly effective adsorbent for ammonia due to the high density of strong Lewis acid sites arising from the boron. GO was doped by various amounts of boron described as xB-GO (x= 1.0, 3.0, and 5.0). B-GO was successful ...
Surface porosity affects the ability of a substance to adsorb gases. The surface fractal dimension D is a measure that indicates the amount that a surface fills a space, and can thereby be used to characterize the surface porosity. Here we propose a new me ...
Contamination of the environment by anthropogenic volatile organic compounds (VOC) became of major concern during the last decades. Present in gas streams of many industrial exhausts, they are harmful and detrimental for both human health and environment e ...
Novel efficient adsorbents for acetaldehyde removal from diluted gas streams (similar to 1300 ppmv) have been developed. The adsorbents combine the properties of activated carbon fibers (ACF) and nanoparticles (NPs) of basic metal oxides (La2O3, CaO, MgO, ...
Typical flue gas streams have low concns. of CO2 and high gas flow rates, making porous materials, such as zeolites, metal-org. frameworks (MOFs), and activated carbons promising options for the future sepn./sequestration of CO2. These framework materials ...
Identification of kinetic models and estimation of reaction and mass-transfer parameters is an important task for monitoring, control and optimization of industrial processes. A methodology called Extent-based Model Identification has been developed to sep ...
The hydrogen storage properties of Fe2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) and an oxidized analog, Fe2(O2)(dobdc), have been examd. using several complementary techniques, including low-pressure gas adsorption, neutron powder diffractio ...
