ChemPhysChem, EarlyView.Relative energies of the cis and trans conformers of the protonated tetrapeptide, Gly‐Pro‐Gly‐Gly, selected by ion mobility spectrometry are measured using threshold collision‐induced dissociation. The trans conformation was found to be more stable than the cis conformation by 4.5 ± 2.5 kJ mol−1 at 0 K, a value in agreement with several levels of ...

International Journal of Satellite Communications and Networking, Volume 41, Issue 1, Page 82-97, January/February 2023., 2023 This paper analyzes which constellation characteristics provide the best global coverage at the lowest operational cost. Our analysis has found that geostationary and medium Earth orbit satellite constellations have the highest likelihood of profitability. LEO networks are more expensive, but if designed wisely, they can be competitive.

Conformation Dependent Room Temperature Phosphorescence in Organic Materials
ChemPhotoChem, EarlyView.Room temperature phosphorescence from organic materials in the solid state can be tuned owing to changes in the molecular arrangement occurring in crystalline and amorphous phases. This review presents recent results that discuss conformation dependent triplet emission, revealing its role in the design of organic functional materials with diverse ...

International Journal of Satellite Communications and Networking, EarlyView., 2023 In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Effect of the Electrolyte on the Oxygen Reduction Reaction with a MOF Embedded Co‐Porphyrin
ChemSusChem, EarlyView.The reduction of dioxygen to hydrogen peroxide in the PCN‐224(Co) MOF is limited by the intrinsic catalytic activity of the cobalt sites rather than the diffusion of charge or the mass‐transport of reagents. The more strongly coordinating cations affect the catalytic activity slightly negatively, while the concentrations of buffer and oxygen ...

International Journal of Satellite Communications and Networking, EarlyView., 2023 The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.
