Cellulose‐Based Electrolytes in Rechargeable Zn‐Battery: An Overview

open access: yesAdvanced Sustainable Systems, EarlyView.
Zn‐ion battery with cellulose‐based electrolyte and diffused cathode such as MnO2 and V2O5 can be actually proposed as a rechargeable system for energy storage from renewable sources such as solar and wind, due to its relevant cycle life and the remarkably competitive low cost.

Experimental and Numerical study of a hydrogen fuelled I.C. engine fitted with the hydrogen assisted jet ignition system [PDF]

open access: yes, 2007
The use of hydrogen as an engine fuel poses several challenges as well as opportunities in engine design and control. These challenges are mainly due to hydrogen's high flame temperatures at near stoichiometric mixtures, as well as the reactant volume ...

Advances and Outlook of Nickel‐Based MOFs–LDHs Materials for Energy Conversion

open access: yesAdvanced Sustainable Systems, EarlyView.
In this graphical abstract, we present the pivotal gap between the activity and stability parameters as far as intergrated Ni‐based MOF/LDF electrocatalysts are concerned. For large scale application, these two parameters should be optimized and furthermore balanced in order to promote sustainable electrocatalytic hydrogen production.
