Flying taxis revived: Can Urban air mobility reduce road congestion?

Journal of Urban Mobility, 2021
: Many metropolitan regions are investigating Urban Air Mobility (UAM) as a new transport mode for medium distance intra-regional trips. In this paper, an agent-based travel demand model was developed to simulate UAM demand for the region surrounding ...

Model study of the earth’s ionosphere electric currents system at high latitudes [PDF]

E3S Web of Conferences
This paper presents a numerical study of the response of high- latitudinal Earth’s ionosphere electric currents system to different magne- tospheric inputs. The ionosphere states were modeled using the Upper At- mosphere Model (UAM).

Breaking the Ceiling of Boron-Boron Bonds: Understanding and Fine-Tuning Basicity in Diborane(4) Complexes. [PDF]

J Comput Chem
Diborane(4) can form strong complexes with one or two nitrogen bases, and still behave as a boron base. Complexed with two nitrogen bases, diborane(4) may reach very high proton affinities, overcoming that of the typical 1,8‐bis(dimethylamino)naphthalene super sponge. However, understanding basicity trends is not straightforward, due to the loss of the

A Mechanical sp2‐Jail for C60 Fullerene

Angewandte Chemie, EarlyView.
A rigid bisporphyrin receptor with an exceptionally compact 3D cavity functions as a molecular “mechanical jail”, tightly enclosing C60 fullerene. Near‐perfect shape complementarity affords ultrahigh binding affinity while imposing a large kinetic barrier for guest exchange, rendering encapsulation effectively irreversible under ambient conditions ...
