The development of a sustainable bio-based economy has drawn much attention in recent years and research to find smart solutions to the many inherent challenges has intensified In nature perhaps the best example of an authentic sustainable system is oxygenic photosynthesis The biochemistry of this intricate process is empowered by solar radiation influx and performed by hierarchically
Environmental context Platinum complexes are widely used to treat cancer however these compounds are also rapidly excreted in the urine of patients and can therefore enter waterways presenting a toxic hazard to the environment The biopolymer chitosan was found to be an effective and fast adsorbent for capturing multiple platinum complexes currently applied in medicine This new approach
We present a new local density functional called M06-L for main-group and transition element thermochemistry thermochemical kinetics and noncovalent interactions The functional is designed to capture the main dependence of the exchange-correlation energy on local spin density spin density gradient and spin kinetic energy density and it is parametrized to satisfy the uniform-electron
