Regenerated papers made from discarded natural sources, such as seaweeds or non-wood plants, are viewed promising eco-friendly alternatives relative to conventional wood-based paper. However, due its limited mechanical strength and higher water absorption than compared traditional wood paper, it often results in premature structural disintegration. In order overcome this limitation, research in...
خلاصه فارسی: به علت وجود مشکلات استفاده از داروهایی با نیمه عمر کوتاه که نیازمند تجویز چند دوز در طی یک روز می باشند، مانند فراموش کردن دریافت دوز دارو و ثابت نبودن سطح خونی و... ضرورت ساخت اشکال modified release واضح و مبرهن است. از میان راه های مختلف دارورسانی به بدن، راه خوراکی به علت مزایای ویژه خود همچنان از جایگاه مهمی در داروسازی برخوردار می باشد. اشکال دارویی متنوعی نیز این امکان را فر...
Tung oil and linseed oil are two representative traditional drying oils wich were commonly employed, for centuries, for wood finishing. Therefore, their study in terms of properties, chemical structure features and alterations by ageing is important for furniture conservation. This paper focusses on some comparative properties of Tung oil and linseed oil as wood finishing materials. For this pu...
Abstract Wood is a natural material and subject to degradation due weather, UV radiation, humidity. composed of many components. The basic structural elements wood include cellulose, hemicellulose, lignin. Furthermore, these are accompanying substances, which also extractive substances. Specifically, together with lignin, have negative effect on its life thanks their chemical reactions, initiat...
Matte coatings have found wide-ranging applications across diverse industries. In this study, self-matting films with surface wrinkles were produced by exposing UV-curable polyurethane acrylate (UV-WPUA) resin to 172 nm Xe2* excimer and medium-pressure mercury lamps. The gloss values, micromorphologies, water contact angles (WCAs), roughness friction behaviors of UV-WPUA different photoinitiato...
Coatings can be used as a preservative method to protect the wood, especially wood surface. The different component of coating’s dependence purpose it. Japanese beech (Fagus crenata Blume) applied by several commercials coating materials. coatings application were spray type and brush type. X-ray microtomography in Fuji, Japan was for visualized samples. target Cu, Mo with Al filter. image anal...
The development of low-cost, scalable wood-based photothermal systems that utilize renewable solar energy for conservation and desalination has received extensive attention. Although some materials such as precious metals, semiconductor carbon nanomaterials have been used light absorbers, the issues low evaporation rate efficiency, well high consumption cost layer design need to be addressed. I...
