Magneto-chiral dichroism is described in terms of devices and synthesis, and is a clue to explain the homochirality of life.

The distribution and prototropic equilibria of 1-naphthol (NpOH) in lipid bilayer membrane.

Photodynamic therapy is a powerful tool in photomedicine. Hydrogels represent very promising candidates to overcome current limitations of this therapeutic technique, such as drug solubility and targeting, and unleash its full potential.

With its principles discovered more than a hundred years ago the photodynamic inactivation of viruses is now routinely employed in the decontamination of blood products but also investigated for HPV treatment and water disinfection and food safety.

Sunlight is a ubiquitous environmental stimulus for the great majority of living organisms on Earth; therefore it is logical to expect the development of “seeing mechanisms” which lead them to successfully adapt to particular ecological niches.

This review represents the most complete description of the scientific results obtained on a photochemical reaction described 110 years ago by an Italian scientist.

Among stimulus-responsive molecular ring-on-thread rotaxanes and pseudorotaxanes, variants incorporating photochromic sub-units are attracting considerable attention as their properties and structure can be remotely and precisely controlled, additionally without producing chemical waste.

Our study describes how organic photochemists can modify the outcome of a reaction by tuning the wavelength.

Photobiomodulation (PBM) describes the application of light at wavelengths ranging from 400–1100 nm to promote tissue healing, reduce inflammation and promote analgesia.

The aim of the present systematic review was to analyze studies that investigated the effects of photobiomodulation therapy on head and neck squamous cell carcinoma cells.

Here we review the state-of-the-art of RCM morphologic descriptors, standardized terminology, and diagnostic algorithms for the assessment of pigmented macules of the face, for their correct diagnosis and management.

Plant UV research is at a juncture, whereby mechanistic knowledge of UV photoreceptor responses needs to be applied to ecologically relevant scenarios and put to practical use in plant production.

Optical coherence tomography angiography (OCTA) is a relatively novel functional extension of the widely accepted ophthalmic imaging tool named optical coherence tomography (OCT).

The Montreal Protocol has limited increases in the UV-B (280–315 nm) radiation reaching the Earth's surface as a result of depletion of stratospheric ozone. Exposure to UV-B radiation has both risks and benefits for human health.

Influence of global change on biogeochemical cycles within and between environmental compartments: cryosphere, terrestrial and aquatic ecosystems, and the atmosphere.

Summary of current knowledge about effects of UV radiation in inland and oceanic waters related to stratospheric ozone depletion and climate change.

Linkages between stratospheric ozone, UV radiation and climate change: terrestrial ecosystems.

Conceptual representation of interactive effects of changes in greenhouse gases and ozone-depleting substances on climate and stratospheric ozone, which together with changes in aerosols, clouds and surface reflectivity determine UV-B radiation at Earth's surface.

Air quality, including gases like ozone and particles, is determined by the complex interaction of emissions and UV radiation.

Solar UV radiation adversely affects the properties of organic materials used in construction, such as plastics and wood.

A systematic evaluation of the uncertainties limiting the application of UV-B-absorbing compounds in pollen and spores to reconstruct UV-B irradiance.

Laser technology has long been a standard treatment for many diseases.

In this perspective article, we discuss the possibilities of integrating liquefied organic and inorganic semiconducting materials with tunable optoelectronic properties into solvent-free fluidic systems of functional optoelectronic materials to generate flexible DSSCs/QDSSCs.
