Cubic CuO nanoparticle modified hydrogel (CMHG) was synthesized to address two major problems (harmful irradiation and high density pathogens) of the current light-emitting screens simultaneously. The as-prepared hydrogel could conveniently form an adjustable semitransparent film over various shaped screens to provide enhanced antibacterial activity and longer CuO service life. More importantly, with the aid of cubic CuO nanoparticles, the energy of the harmful blue light irradiation could be effectively transformed into a photocatalysed power source to sterilize the surface of the screen. This low toxic CMHG showed no significant influence on the touch control experience, and had obvious eye protective effects, which thus offered a convenient manner to protect vision and sterilize touch screens at the same time.

Background: Previous studies have proven that 308-nm light-emitting diode(308-nm LED)and 308-nm excimer lamp(308-nm MEL) are effective in treating vitiligo, but there is a lack of comparison of their efficacy for facial lesions.
Objective: To evaluate and contrast the treatment success rates of 308-nm LED versus 308-nm excimer lamp in managing facial lesions among patients suffering from stable non-segmental vitiligo.
Methods: The enrolled 119 patients with 145 lesions were randomly assigned to receive 308-nm LED or 308-nm MEL for two months.

A method for correlating reaction conditions with device performance was developed by combining Design-of-Experiments and machine-learning strategies in multistep device fabrication processes. This method allowed the "from-flask-to-device" optimisation of a macrocyclisation reaction yielding a mixture of methylated []cyclo--phenylenes, and a crude raw material was directly applied to the fabrication of Ir-doped organic light-emitting devices spin-coating. The method succeeded in eliminating energy-consuming and waste-producing separation and purification steps during device fabrication.

The pupillary direct and consensual reflex is an important non-invasive quick assessment of the neurological state of the eye. Currently, there is no cheap and affordable recording tool for screening and documentation of a relative afferent pupillary defect. We describe how to construct a frugal, do-it-yourself handheld scotopic binocular pupillometer device called Pupilmate.

Shortwave infrared (SWIR)-emitting materials have emerged as superior light sources with increasing demand for potential applications in noninvasive analysis, night vision illumination, and medical diagnosis. For developing next-generation SWIR phosphor-converted light-emitting diodes (pc-LEDs), the scarcity of intense blue-light-pumped broadband SWIR luminescent materials and poor thermal stability of current Ni-activated phosphors are the ongoing challenges. Here, a blue-light-excitable (440 nm) YAlGaO:Cr,Ni phosphor with ultrawide SWIR emission centered at ∼1430 nm (FWHM ∼264 nm) is reported.
