Satellite communications shall only thrive if being able to compete with fibre in both bandwidth and cost. Here, the authors demonstrate that a coherent and yet modular photonic-aided payload is feasible, paving the way for a new generation of commun

In this study, we report the preparation of new mono-charged benzoporphyrin complexes by reaction of the appropriate neutral benzoporphyrin with (2,2′-bipyridine)dichloroplatinum(II) and of the analogs’ derivatives synthesized through alkylation

Worldwide, millions of people are exposed to dietary imbalance that impacts in health and quality of life. In developing countries, like in Brazil, in poor settings, dietary habits, traditionally hypoproteic, are changing rapidly to western-type high

Novel triazole-porphyrin derivatives (TZ-PORs) were synthesized through the Heck reaction and then incorporated into polyvinylpyrrolidone (PVP) micelles. After verifying that this incorporation did not compromise the photophysical and chemical featur

Ubiquitous satellite communications are in a leading position for bridging the digital divide. Fulfilling such a mission will require satellite services on par with fibre services, both in bandwidth and cost. Achieving such a performance requires a n

In this Letter, we propose a monitoring and control system (MCS) for operating tunable optical delay lines (TODLs), regardless of their operation principle and implementation technology. The monitoring system resorts to two out-of-band pilot tones ad

It has been reported that the hippocampus is very susceptible to methamphetamine (METH) and that neuropeptide Y (NPY) is an important neuroprotective agent against hippocampal excitotoxicity. However, there is very little information regarding the ro

We demonstrate a silicon photonic 4×1 TTD beamformer operated in real-time. Beamforming of a 1 Gb/s QPSK signal carried at 28 GHz was validated by a fourfold improvement in output amplitude and EVM.
