A Guideline to Evaluate Sorbent Performance for Atmospheric Water Harvesting

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Reporting guidelines for atmospheric water harvesting sorbents allow benchmarking between research groups across seven key performance indicators (KPIs). Beyond simple equilibrium values (such as capacity or maximum water uptake), these KPIs validate sensitivity, reversibility, regeneration conditions, chemical stability, kinetics, and water quality ...

A critical review of porous adsorbents for air separation: From fundamental insights to rational adsorbent design

open access: yesAIChE Journal, EarlyView.
Abstract Air separation via selective adsorption using porous adsorbents offers energy‐efficient alternatives to cryogenic distillation for producing high‐purity O2 and N2. Adsorbent efficacy depends on balancing selectivity, durability, and performance consistency across varying conditions. This comprehensive review critically discusses the design and

Treatment Efficiency of Electrocoagulation Combined with Different Particle Sizes of Natural Zeolite [PDF]

open access: yesKemija u Industriji
In a previous study, the larger size of synthetic zeolite particles was highlighted as better choice for electrocoagulation combined with zeolite (ECZ). This choice resulted in a smaller rise in pH and temperature, a more significant decline in turbidity
