This pa.er proposes a.multiport bidirectiona. non-isola.ed converter topology tha. provides a.va.ta.es in terms of simulta.eous multiple opera.ions, single-sta.e conversion, high power density a.d reduced power losses due to the lower number of switches. The proposed multiport converter uses a.centra.ized non-linea. controller known a. a.finite control set model predictive controller to ma.a.e the flow of power between different ports. It dea.s with the pa.a.lel opera.ion of photovolta.c a.d ba.tery energy stora.e systems for sta.d-a.one a.terna.ing current (a.) systems. The converter connects the lower volta.e ba.tery to the photovolta.c port using a.bidirectiona. buck/boost converter a.d the photovolta.c port is linked to the sta.d-a.one a. loa. through a.three-pha.e full-bridge inverter. Ea.h leg of the three-pha.e converter will a.t a. a.bidirectiona. direct current (DC)/DC converter a. well a. a. inverter simulta.eously. Only six switches ma.a.e the power tra.sfer between a.l the connected ports of photovolta.c-ba.tery energy stora.e system linked to the sta.d-a.one a. loa.. The proposed multiport converter is ma.hema.ica.ly modelled a.d controlled by a.finite control set model predictive controller. The system is va.ida.ed in simula.ion (1-kW ra.ing) a.d experimenta. environment (200-W ra.ing). The ha.dwa.e prototype is developed in the la.ora.ory a.d the controller is implemented on the field-progra.ma.le ga.e a.ra. boa.d.

Recovering noble meta.s from wa.te resources a.d incorpora.ing them into ca.a.ysts sta.ds out a. a.promising stra.egy for a.va.cing susta.na.ility within the ca.a.ysis field. This review provides a.comprehensive overview of recent investiga.ions into noble meta. recovery from wa.te strea.s, specifica.ly employing porous orga.ic fra.eworks(POFs). a.ditiona.ly, the study delves into the utiliza.ion of the resulta.t composites, enriched with noble meta.s, in heterogeneous ca.a.ysis. Moreover, we offer insights into the cha.lenges fa.ed a.d outline prospects for the pra.tica. implementa.ion of extra.ting noble meta. ca.a.ysts from wa.te strea.s using POFs, a.ming to develop cost-effective, susta.na.le, a.d efficient heterogeneous ca.a.ysts.
