Summary: A novel Pumped Thermal Energy Storage (PTES) system integrated with a Concentrating Solar Power (CSP) plant is proposed and investigated. The system operates with the same working fluid as the CSP plant and includes a Thermal Energy Storage (TES) system composed of three packed-bed tanks. Mathematical models were developed to simulate the system's performance and evaluate the thermal profiles of the TES tanks. A feasible design with an exergetic roundtrip efficiency of about 60% was proposed based on the results.

Summary: By integrating a selected PCM within the structure of an evacuated tube solar hot water system, a novel PCM-based self-storing design is proposed. This design can maintain the collector output temperature at around 63 degrees C after 15 h of not receiving any sunlight, while the output temperature of the normal collector drops down to ambient temperature in the same period. The obtained energy storage efficiency is 57% and 75%, and overall thermal efficiency is 49% and 72%, for the normal and the self-storing collectors, respectively. For the smallscale system used in this study, the proposed design helps reduce the size of the hot water storage tank required to supply the hot water demand by 55%.

Summary: The role of alumina support precursors in Cu-Fe/Al2O3 catalysts for the total oxidation of toluene has been elucidated, with important factors being the structural order of the support precursor, homogeneous distribution of catalytic sites, and metal oxide distribution on the support. Homogeneous distribution of FexOy and CuOx with defined Cu/Fe molar ratio on the Al2O3 support is required for efficient catalytic performance. Introducing low iron concentration during alumina support synthesis procedure leads to a beneficial effect of homogeneous metal oxide distribution on the support.

Summary: This study examined the potential heat storage applications of two different sodalite-type ZIF structures (ZIF-8 and ZIF-90) for adsorption of water, methanol and ethanol, with ZIF-90-water showing the best desorption enthalpy, fastest sorption kinetics and highest potential for heat storage/reallocation applications. This was attributed to ZIF-90's significantly smaller particle size, higher specific surface area, and presence of mesoporosity and polar groups compared to ZIF-8.

Summary: Transition metals as catalysts for total VOC oxidation at low temperatures are challenging. This study prepared and tested iron-modified SBA-15, AlSBA-15, and ZrSBA-15 materials with varying Fe loading for toluene oxidation. The results showed that increasing Fe loading improved the oxidation rate and decreased the temperature required for complete toluene removal. Surface properties of the mesoporous support influenced the type and localization of iron oxide species, and 5 wt. % Fe-containing ZrSBA-15 exhibited excellent activity in the total oxidation of toluene at lower temperatures due to the synergistic effect of Fe-Zr and the presence of accessible and stable Fe2+/Fe3+ active sites.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor.
