Image Plane Holographic Microscopy With a Table-Top Soft X-Ray Laser

open access: yesIEEE Photonics Journal, 2015
We demonstrate image plane holographic microscopy in the soft X-ray (SXR) spectral region, combining the coherent output from a 46.9-nm wavelength table-top SXR laser and two Fresnel zone plates.

Observation of Highly Durable Silicone Resin for Encapsulating AlGaN-Based UVB Light-Emitting Diodes

open access: yesApplied Sciences, 2021
In this paper, we report an AlN-based ceramic lead frame (LF) with encapsulating silicone between the surface of an AlGaN-based ultraviolet-B light-emitting diode (UVB-LED) chip and a quartz glass cover; the light output power (LOP) of this structure was

Ultraviolet B but not Ultraviolet A Radiation Initiates Melanoma [PDF]

open access: yesCancer Research, 2004
Abstract Cutaneous malignant melanoma is one of the fastest increasing cancers with an incidence that has more than doubled in the last 25 years. Sunlight exposure is strongly implicated in the etiology of cutaneous malignant melanoma and the UV portion of the sunlight spectrum is considered responsible. Data are, however, conflicting

Effects of tocotrienol on aging skin: A systematic review

open access: yesFrontiers in Pharmacology, 2022
The skin is the largest organ of the body that protects from mechanical, thermal, and physical injury. However, the function and appearance of skin visibly degenerates with age due to its frequent exposure to harmful effects of the environment, including
