Polyporous PVDF/TiO2 photocatalytic composites for photocatalyst fixation, recycle, and repair

“…Modeling of infiltration of liquids in porous media is a well-studied subject, especially in the field of hydrology where it is used to model seepage of water through porous soils and rocks. 29,30 The physics of resin flow into a mold under pressure is similar to the seepage problem and so similar approaches have been used also to model the flow of resin into a mold containing fiber mats. 23,[31][32][33][34][35][36][37][38] The models are used in these cases to determine the resin flow front and mold filling times corresponding to different infiltration conditions.…”

“…The prepregged fabric was next cut UV than Vis,resulting from the energy band gap PVDF of ~6.5 eV. 30 RhB is stable under light irradiation and its selfdecomposition under UV is negligible. After UV irradiation for 150 min, 38.4% of RhB is degraded by PVDF.…”

H2S and NH3 adsorption characteristics on CoO nanowire molecular device – A first-principles study

“…The current through the scattering region can be calculated using Landauer-Buttiker formula [24] where G 0 =2e 2 /h is the quantum conductance and T(E, V b ) is the transmission probability of the electron under the bias, V b . Transmission energies and the density of states are calculated using the post processing tool TBTRANS [25] available in SIESTA package.…”

Strong Polarity Asymmetry and Abnormal Mechanical Electroresistance Effect in the Organic Monolayer Tunnel Junction

“…Poly­(vinylidene fluoride) (PVDF) and its copolymer with trifluoroethylene (TrFE) thin films have attracted intensive research interest due to their flexibility and the exhibition of ferroelectricity down to the monolayer. , With the observation of diode-like transport behavior in P­(VDF-TrFE) thin film with a few monolayers, PVDF and P­(VDF-TrFE) monolayers are considered as promising candidates in developing organic ferroelectric tunnel junctions (FTJs) − and multiferroic tunnel junctions (MFTJs). − Similar to that of inorganic tunnel junctions, − the performance of these organic tunnel junctions is highly correlated to the asymmetric polarization stability and the interfaces as well. For example, by utilizing n-type semiconductor Nb:SrTiO 3 (STO) as the bottom electrode, Majumdar et al exploited an extra barrier over the space charge region at the interface of P­(VDF-TrFE)/Nb:STO and raised the OFF/ON ratio up to 10000.…”
