Adsorption and melting of hydrogen in potassium-intercalated graphite
Volumetric adsorption and quasielastic neutron scattering are used to study the diffusion and thermodynamics of sorbed H2 in the graphite intercalation compound KC24. A sorption enthalpy of 8.5 kJ/mol at zero coverage is determined from H2 adsorption isotherms. From measurements of total elastic-neutron-scattering intensity as a function of temperature, a melting transition of the H2 adsorbate ...
متن کاملThermal Behavior and Decomposition of Intercalated Kaolinite
-Intercalation complexes of a Hungarian kaolinite were prepared with hydrazine and potassium acetate. The thermal behavior and decomposition of the kaolinite-potassium acetate complex was studied by simultaneous TA-EGA, XRD, and FTIR methods. The intercalation complex is stable up to 300"C, and decomposition takes place in two stages after melting of potassium acetate intercalated in the interl...
متن کاملPhoto- and thermionic emission from potassium-intercalated carbon nanotube arrays
Carbon nanotubes CNTs are promising candidates to create new thermionicand photoemission materials. Intercalation of CNTs with alkali metals, such as potassium, greatly reduces their work functions, and the low electron scattering rates of small-diameter CNTs offer the possibility of efficient photoemission. This work uses a Nd:YAG YAG denotes yttrium aluminum garnet laser to irradiate singlean...
متن کاملPotassium-intercalated H2Pc films: alkali-induced electronic and geometrical modifications.
X-ray spectroscopy studies of potassium intercalated metal-free phthalocyanine multilayers adsorbed on Al(110) have been undertaken. Photoelectron spectroscopy measurements show the presence of several charge states of the molecules upon K intercalation, due to a charge transfer from the alkali. In addition, the comparison of valence band photoemission spectra with the density functional theory...
متن کاملVolume anomaly in ferrimagnetism
2014 The volume anomaly 0394V/V due to the magnetic energy corresponding to the exchange interactions is experimentally determined for YIG. The experimental values (from 77 K to Tc) agree with the values deduced from the theoretical expression based on the Néel’s theories of volume anomaly and of ferrimagnetism. These results are compared with those obtained by other authors on ferromagnetic an...
