Has the time finally come for green oleochemicals and biodiesel production using large-scale enzyme technologies? Current status and new developments.

With the growth of the chemical industry over the last decade, the need for cheaper (and more environmentally friendly) alternatives to petrochemicals of ever-increasing cost has grown steadily. Oleochemicals and biodiesel (OC/BD) are considered as green alternatives to petroleum derivatives, because they come from renewable oils and fats. OC/BD are currently produced by the traditional energy intensive chemical catalyzed methods, which have several economic and environmental drawbacks.

Insights into the pressure-dependent physical properties of cubic CaMF (M = As and Sb): First-principles calculations.

Here, first-principles calculations have been employed to make a comparative study on structural, mechanical, electronic, and optical properties of new CaMF (M = As and Sb) photovoltaic compounds under pressure. The findings disclose that these two systems possess a direct band gap, showcasing a large tunable range under pressure, effectively encompassing the visible light spectrum. Adjusting various levels of hydrostatic pressure has effectively tuned both the band alignment and the effective masses of electrons and holes.

A DFT investigation of lead-free TlSnX (X = Cl, Br, or I) perovskites for potential applications in solar cells and thermoelectric devices.

In the present study, the Density Functional Theory (DFT) was employed to computationally investigate the potential application of newly developed lead-free perovskites with the formula of TlSnX (X = Cl, Br, or I) as absorbers in the perovskite solar cells and as thermoelectric materials. The Quantum Espresso code was implemented to optimize the structural configuration of the perovskites and to compute a range of their properties, including their elasticity, electronic behavior, optical characteristics, and thermoelectric attributes. The findings indicated that these perovskite materials exhibit both chemical and structural stability and that TlSnBr and TlSnI perovskites possess high dynamic stability.
