Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Pigment analysis by Raman microscopy and portable X-ray fluorescence (pXRF) of thirteenth to fourteenth century illuminations and cuttings from Bologna [PDF]
Non-destructive pigment analysis by Raman microscopy (RM) and portable X-ray fluorescence (pXRF) has been carried out on some Bolognese illuminations and cuttings chosen to represent the beginnings, evolution and height of Bolognese illuminated ...

Designing Physical Unclonable Functions From Optically Active Materials
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Commercial Applications of Microalgae [PDF]
The first use of microalgae by humans dates back 2000 years to the Chinese, who used Nostoc to survive during famine. However, microalgal biotechnology only really began to develop in the middle of the last century.

Synthetic Chromatophores for Color and Pattern Morphing Skins
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Evidence of late Quaternary environmental change in a continental east Antarctic lake from lacustrine sedimentary pigment distributions [PDF]
A sediment core from Progress Lake, one of the oldest lacustrine sequences in East Antarctica, contains distinct zones dating from a previous interglacial (most likely Marine Isotope Stage 5e, c.

By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...
