Power over Fiber (PoF) needs safe and resilient operation of the infrastructure. In this article, we propose a new crosstalk-based remote monitoring technique of PoF signals in Spatial Division Multiplexing optical networks with no additional consumption at the remote radio head (RRH). We demonstrate this technique in a 250 m 7-core Multicore Fiber (MCF) transmitting three multiplexed 256 QAM 5G NR optical signals with a total throughput of 1.8 Gbps, a low-speed communications channel between a Central Office and a RRH, and a PoF signal delivering to feed the RRH's control board. The 5G NR optical signals are received at the RRH with EVM values within the limits stablished in the 3GPP 5G standard. The low-speed communications channel remotely manages the power supplied to a Radio Frequency Power Amplifier located at the RRH. The PoF signal is used to supply up to 131 mW to the control board of the RRH. The monitoring channel can accurately follow the optical power injected into the MCF or the optical power received at the RRH thanks to a real-time algorithm and an ad-hoc Matlab application, which also allows to control the PoF source and the low-speed communications channel.

In this work, the support effect and the La2O3 promotion of Ni-based catalysts on the oxidative steam reforming of acetic acid as bio-oil model compound has been studied. Ni/SBA-15 showed the worst catalytic performance with an acetic acid conversion dropping below 30% at 500 ºC ascribed to active phase oxidation. In contrast, Ni supported over mesoporous CeO2 (CeO2-m) reached better catalytic performance and lower coke formation due to the higher Ni dispersion and oxygen mobility of the support. On the other hand, La2O3 promotion to SBA-15 and CeO2-m led to even higher Ni dispersion and prevented sintering during the reforming reaction. This effect resulted in an improvement in the catalytic performance for both promoted samples. As a consequence of low Ni crystallite size and high oxygen mobility, Ni/La2O3-CeO2-m reached almost complete conversion (~ 96%), the highest hydrogen yield (~ 53%) maintained for 5 h with the lowest coke formation (62.3 mgcoke·gcat 1·h 1).

Lignocellulosic biomass offers a sustainable alternative to traditional raw materials. However, its complex structure, and particularly the presence of lignin, presents a significant challenge for its conversion into valuable products. This study explores the catalytic performance of magnesium oxide (MgO) based materials for the selective delignification of lignocellulosic waste and concomitant carboxylic acids production. Different MgO samples have been synthesized through various synthetical methods with the purpose of promoting the selective delignification of a lignocellulose waste while minimizing the degradation of other polymers (cellulose and hemicellulose). The resultant lignin-free holocellulose solid after selective depolymerization might be used in subsequent fermentation processes. The catalytic results demonstrated that MgO synthesized by a sol-gel method exhibited the highest catalytic activity, achieving ca. 90% lignin conversion with minimal degradation of cellulose and hemicellulose and outstanding production of carboxylic acids (ca. 30 % of the carbon of the degraded polymers was converted into carboxylic acids). The high concentration of medium-strength base sites combined with significant macroporosity are crucial for enhancing the catalytic performance of MgO-based catalysts. Importantly, these results were achieved under mild conditions (120°C) using water as a solvent and without addition of external oxidant agents. Furthermore, the study observed a significant production of valuable (di)carboxylic acids, such as fumaric acid during the depolymerization process over optimized MgO catalyst. This research provides valuable insights into the potential of MgO as a sustainable catalyst for the selective conversion of lignin present in lignocellulosic biomass into valuable chemicals and biofuels.
