Numerical simulation and theoretical study on effects of operating parameters in Persian Gulf desalination using vacuum membrane distillation [PDF]
مجله مدل سازی در مهندسی, 2018 The Persian Gulf and its coastal areas are considered to be the largest source of crude oil in the world. On the other hand, the waste heat from the refining and petrochemical industries located around the Persian Gulf region can be used based on simple ...

Temperature-dependent polarization in a non-polar crystal [PDF]
Nature, 2019 A crystal’s surface has been found to behave as a distinct material that has temperature-dependent electrical polarization — despite the rest of the crystal being non-polar. Pyroelectricity in the surface layers of strontium titanate.

Lensing reconstruction with CMB temperature and polarization [PDF]
Physical Review D, 2003 Weak gravitational lensing by intervening large-scale structure induces a distinct signature in the cosmic microwave background (CMB) that can be used to reconstruct the weak-lensing displacement map. Estimators for individual Fourier modes of this map can be combined to produce an estimator for the lensing-potenial power spectrum.

Observation of room-temperature polar skyrmions [PDF]
Nature, 2019 Complex topological configurations are fertile ground for exploring emergent phenomena and exotic phases in condensed-matter physics. For example, the recent discovery of polarization vortices and their associated complex-phase coexistence and response under applied electric fields in superlattices of (PbTiO3)n/(SrTiO3)n suggests the presence of a ...

CFD Investigation of Spacer-Filled Channels for Membrane Distillation
Membranes, 2019 The membrane distillation (MD) process for water desalination is affected by temperature polarization, which reduces the driving force and the efficiency of the process. To counteract this phenomenon, spacer-filled channels are used, which enhance mixing

Temperature inversion of the thermal polarization of water [PDF]
Physical Review E, 2015 Temperature gradients polarize water, a nonequilibrium effect that may result in significant electrostatic fields for strong thermal gradients. Using nonequilibrium molecular dynamics simulations, we show that the thermal polarization features a significant dependence with temperature that ultimately leads to an inversion phenomenon, whereby the ...

Electrocaloric effect and freezing temperature in (Pb0.8Ba0.2)[(Zn1∕3Nb2∕3)0.7Ti0.3]O3 relaxor ferroelectric ceramic [PDF]
Journal of Advanced Dielectrics, 2016 The electrocaloric effect (ECE) is studied in (Pb0.8Ba0.2)[(Zn1∕3Nb2∕3)0.7Ti0.3]O3 relaxor ferroelectric ceramic by using an “indirect method”. The electric dependence for the polarization (hysteresis loops) has been obtained for several temperatures ...

Heat and Mass Transport in Modeling Membrane Distillation Configurations: A Review
Frontiers in Energy Research, 2018 Identification and mitigation of challenges associated with membrane distillation (MD) modeling are very crucial to the applicability of MD technology in the industry. Several research studies have been carried out on direct contact membrane distillation

CMB temperature and polarization anisotropy fundamentals [PDF]
Annals of Physics, 2003 The tremendous experimental progress in cosmic microwave background (CMB) temperature and polarization anisotropy studies over the last few years has helped establish a standard paradigm for cosmology at intermediate epochs and has simultaneously raised questions regarding the physical processes at the two opposite ends of time.
