Rarefaction wave in relativistic steady magnetohydrodynamic flows [PDF]
, 2014 We construct and analyze a model of the relativistic steady-state magnetohydrodynamic (MHD) rarefaction that is induced when a planar symmetric flow (with one ignorable Cartesian coordinate) propagates under a steep drop of the external pressure profile.

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

A novel laser-based stereotactic localization device for intracranial mass resection
Brain Hemorrhages, 2021 Unfortunately, both frame-based and frameless stereotactic neuronavigation platforms are far from ubiquitous in global neurosurgery, and many facilities lack accurate localization technology to ensure the safety of intracranial surgery such as cerebral ...

The conservation equations for multicomponent gas mixtures in arbitrary coordinate systems [PDF]
, 1958 The conservation equations for multicomponent reacting gas mixtures are generally given only in Cartesian or orthogonal curvilinear coordinate systems. Actually, the conservation equations are easily expressed in an arbitrary coordinate system.

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions
Advanced Functional Materials, EarlyView.Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...
