This work aims to explore how micro-/nano-ZnO particles enhance the mechanical, photoaging and self-cleaning properties of the water-borne acrylic coating. ZnO particles (at 2 wt.% by weight of total solid resin) were dispersed into the acrylic polymer ma... see more

In this work we present spectroscopic and photoluminescent properties of nanostructured polymeric composite films of nanocrystalline TiO2 and polyfuorenes (PF+nc-TiO2). The films were deposited onto glass and KBr substrates by spin-coating PF-in-toluene s... see more

Paper description:Rubus chingii Hu possesses antioxidant, anti-inflammatory and anti-aging activities.The ethanol extract of the fruit (E-EA) demonstrated significant anti-photoaging properties in UVB-induced human fibroblast (HFF-1) cells, observed as a ... see more

Introduction: Postmen are daily exposed to high levels of solar radiation, and lack of protection can result in many health damages. The present study aimed to identify cutaneous phototypes and evaluate the intake of oral photoprotectors by postmen.M... see more

Since the early days of human life on the Earth, our skin has been exposed to different levels of light. Recently, due to inevitable consequences of modern life, humans are not exposed to adequate levels of natural light during the day but they are overex... see more

Background: With increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. The changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the env... see more

Waste of Virgin Coconut Oil (VCO) industries has a high value of Chemical Oxygen Demand (COD), it is therefore a problem for the environment. This waste contains organic materials such as oil, proteins, carbohydrates and some minerals, that potentially to... see more

The development in digital screen technology has exponentially increased in the last decades, and many of today’s electronic devices use light-emitting diode (LED) technology producing very strong blue light (BL) waves. Long-term exposure at LED-BL ... see more

With the rapid development of the photovoltaic industry, fault monitoring is becoming an important issue in maintaining the safe and stable operation of a solar power station. In order to diagnose the fault types of photovoltaic array, a fault diagnosis m... see more
