Adsorption of volatile organic compounds by industrial porous materials: Impact of relative humidity
Atomically thin two-dimensional materials have emerged as promising candidates for flexible and transparent electronic applications. Here we show non-volatile memory devices, based on field-effect transistors with large hysteresis, consisting entirely of stacked two-dimensional materials. Graphene and molybdenum disulphide were employed as both channel and charge-trapping layers, whereas hexago...
considering the potential benefits of edible coatings and films for storage of food materials, effect of edible calcium alginate film on shelf life of frozen lamb muscles was studied in the present research. microbial analyses including total microorganisms count and psychrophilic bacteria count and chemical analyses such as total volatile nitrogen (tvn) and moisture content determination were ...
The d iffractometer cryostat described earlier has been modified to provide a means for controlling temperature and fo r confining the vapor in equilibrium wit h volatile samples. Materials with vapor pressures as great as 1 atmosphere (atm) can be handled without loss of insulatin g vacuu m, a nd temperatures can be controlled with an accuracy of ± 0.1 OK in t he range 4 to 20 OK dec reasing t...
Remarkably volatile magnesium complexes have been prepared with the modified borohydride ligand N,N-dimethylaminodiboranate, H(3)BNMe(2)BH(3)(-). The homoleptic complex Mg(H(3)BNMe(2)BH(3))(2), its monoadducts with tetrahydrofuran and 1,2-dimethoxyethane, and the mixed ligand complex (C(5)Me(5))Mg(H(3)BNMe(2)BH(3))(thf) have been prepared. The homoleptic complex Mg(H(3)BNMe(2)BH(3))(2) has a va...
Introduction: One of the characteristics that makes Earth a suitable environment for the origin of life is the presence of significant amounts of water and other volatile materials. It is thought that Earth formed by the accretion of a large number of small, rocky planetesimals which formed in the inner part of the Sun’s protoplanetary nebula (Wetherill 1990). However, protoplanetary nebula mod...
Although volatile organic compounds (VOCs) are becoming increasingly recognized as harmful agents and potential biomarkers, selective detection of the organic targets remains a tremendous challenge. Among the materials being investigated for target recognition, peptides are attractive candidates because of their chemical robustness, divergence, and their homology to natural olfactory receptors....
The MESSENGER Gamma-Ray Spectrometer measured the average surface abundances of the radioactive elements potassium (K, 1150 ± 220 parts per million), thorium (Th, 220 ± 60 parts per billion), and uranium (U, 90 ± 20 parts per billion) in Mercury's northern hemisphere. The abundance of the moderately volatile element K, relative to Th and U, is inconsistent with physical models for the formation...
