Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite

open access: yesAdvanced Materials, EarlyView.
A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.

An analysis of the Darwin model of approximation to Maxwell’s equations

open access: yesForum Mathematicum, 1992
Summary: This paper is concerned with the approximation of the Maxwell equations by the Darwin model, with appears as a correction of the quasi- electrostatic model, including the electric fields generated by magnetic induction. This model is obtained by neglecting the solenoïdal part of the displacement current in the Maxwell equations, and exhibits ...

A Numerical Technique for Solving the Maxwell Model for Free Surface Flows

open access: yesTrends in Computational and Applied Mathematics, 2004
This work is concerned with the development of a numerical technique for solving free surface flows of a Maxwell fluid. The governing equations for the flow of a Maxwell type fluid together with appropriate boundary conditions are given. The free surface

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.
