Evolution has ensured that plants and animals have developed effective protection
mechanisms against the potentially harmful effects of incident ultraviolet radiation (UVR) …

As demonstrated during the COVID-19 pandemic, advanced deep ultraviolet (DUV) light
sources (200–280 nm), such as AlGaN-based light-emitting diodes (LEDs) show excellence …

Conspectus The intrinsic fluorescence of nucleic acids is extremely weak compared to that
of the fluorescent labels used to probe their structural and functional behavior. Thus, for …

Biochemical reactions are subject to the particular environmental conditions of planet earth,
including solar irradiation. How DNA responds to radiation is relevant to human health …

We demonstrate the generation of few-cycle deep ultraviolet pulses via frequency
upconversion of 5-fs near-infrared pulses in argon using a laser-fabricated gas cell. The …

Solar radiation was overwhelmingly the largest source of energy on the early Earth. Energy
provided by the Sun has the potential to access different chemistries than energy provided …

The knowledge of the fundamental processes induced by the direct absorption of UV
radiation by DNA allows extrapolating conclusions drawn from in vitro studies to the in‐vivo …

The steady-state and time-resolved photochemistry of the natural nucleic acid bases and
their sulfur-and nitrogen-substituted analogues in solution is reviewed. Emphasis is given to …

The study concerns the relaxation of electronic excited states of the DNA nucleoside
deoxycytidine (dCyd) and its methylated analogue 5-methyldeoxycytidine (5mdCyd), known …

Ab initio molecular dynamics simulations have been performed in order to investigate the
relaxation dynamics of uracil after UV excitation in gas phase. Intersystem crossing (ISC) …
