Our recent contribution in #HydrogenEnergy. Herein, we theoretically stabilize the subsititution of chalcogens in BaZrO3 perovkite-oxide by co-dopant mechanism. Our results indicate that introducing Ti as a co-dopant in Chalcogen-doped BaZrO3 not only improves the thermodynamics of introducing an chalcogen atom at oxygen-site under optimal chemical environment, it also allows tuning the band gap of cubic BaZrO3 for absorption of radiation in the visible spectrum. We also perform a side-by-side comparison of the photocatalytic water molecule dissociation efficiency of pristine, Chalcogen-doped, Ti-doped and Ti-Chalcogen co-doped BaZrO3 to examine their potential applications in hydrogen evolution processes. Lastly, we proposed the potential candidate for hydrogen evolution process by photocatalytic mechanism. A must read article.

My latest work on the impact of calcination conditions on the properties of high-Ni, Co-free cathodes is published in Advanced Energy Materials! With a systematic investigation of how calcination temperature and LiOH ratio influence Li/Ni mixing, my work challenges the conventional wisdom about the impact of Li/Ni mixing, which is believed to be detrimental to cycle life. I found that it is not a good indicator of cathode stability, as high mixing can lead to better cycle life and low mixing can lead to worse cycle life. Read more to understand its nuance! Thanks to Dr. Cheng Li from Oak Ridge National Lab for the collaboration and for conducting neutron diffraction experiments. #lithiumbatteries #cobaltfree #cathode

The hierarchical nanostructure consisting of transition metal dichalcogenides and graphitic heteroatom-doped carbon with an abundant interfacial M–N–C catalytic site is highly demanding for electrolytic applications. Herein, we report crystallinity-engineered ultrathin MoS2 nanosheets hierarchy over nitrogen-doped graphitic carbon (NC) hollow spheres as a promising material for HER.

What can #deuterium do for #OLED #displays? Recent advances in R&D and improved manufacturing have significantly increased the longevity of #OLED_displays. Deuterium is already being used in novel #OLED manufacturing processes and R&D, as it was found to grant stabilization properties. Due to a neutron's presence, the atomic mass of deuterium is twice as much as protium – the most common #isotope of #hydrogen. Therefore, deuterium’s bond lengths and bond #energy are also different from those of protium. These changes are known as kinetic isotope effects (KIE)... read more https://lnkd.in/e3rSkb5c #deuterated_benzene #deuterated_solvent #mesbah_energy

The coexistence of exceptional photocatalytic properties and robust spin-orbit coupling within MoSSe, attributable to its structural inversion asymmetry, presents a promising avenue for exploration. Upon the application of an external magnetic field, this synergy amplifies catalytic efficiency, rendering the process more environmentally sustainable and efficacious. We have successfully validated a proof-of-concept for "Spin-manipulated Photo-electrochemistry" employing Janus MoSSe. This breakthrough (published in JMCA) holds the potential to catalyze a host of applications and innovations in the realm of renewable energy, as well as within the domains of advanced materials and magnetism.
