The direct use of naturally occurring,small molecular ingredients in bioinspired sunscreens has raised several concerns due to the instability,photocytotoxicity,and potential blood toxicity of those *** this work,we have employed natural ultraviolet(UV)-blocking molecule caffeic acid phenethyl ester(CAPE)from propolis to prepare poly(CAPE)nanoparticles(NPs)as the main bioactive ingredient to fabricate propolis-inspired hydrogel *** with small molecular CAPE,poly(CAPE)NPs exhibited better dispersion and stability in water,as well as lower physiological toxicity and skin *** the resulting composite hydrogels demonstrated promising properties including water-resistant whereas can be easily erased by warm water as well as safety when interacting with *** importantly,the hydrogel sunscreens showed excellent UV protection properties both in vitro and in vivo,and the positive effects in maintaining skin barrier *** work provides new strategies towards the facile construction of nature-inspired robust sunscreens in the future.

A translucent wooden substrate with long-lasting phosphorescence,high photostability and durability,tough surface,ultraviolet protection,high optical transmittance,and superhydrophobicity was *** long-lasting phosphorescent wooden substrate is able to continue emitting light for extended time ***-modified wood(LMW)was immobilized with a solution of epoxy resin(ER)and rare-earth doped aluminate(REDA)phosphor nanoparticles(NPs).For an improved dispersion of pigment,REDA was synthesized in a nanoscale particle size,and characterized by transmission electron microscopy(TEM)to indicate a particle size of 8-14 *** crystal structure of REDA nanoparticles was also proved by X-ray diffraction(XRD).For an improved production of long-persistent phosphorescent colo rless woods,REDA must be well-dispersed in MAA without *** and emissio n,as well as decay and lifetime spectra were *** morphologies of the wooden substrates with different ratios of REDA were investigated by scanning electron microscopy(SEM),X-ray fluorescence(XRF)analysis,Fourier transform infrared spectra(FT-IR),elemental mapping,and energy-dispersion Xray(EDXA).The phosphorescent woods show changes in color from colorless to green under ultraviolet(UV)irradiation,and to yellowish-green in the dark,as proved by the colorimetric parameters of the CIE Lab *** afterglow wood samples display an absorbance band at 365 nm and two phosphorescent bands at 431 and 520 *** UV shielding,photostability,and hydrophobicity were *** increasing REDA ratio,both static contact and slide angles are found to improve in the ranges of147.6°-163.6°and 9°-14°,*** long-lasting photoluminescence is optimized at a REDA ratio of 8%.The present strategy shows a large-scale production approach of multiple functional woods for many potential applications,such as smart glow in the dark windows and safety signs.
