Transition metal dichalcogenides (TMDs) represent a family of materials with versatile electronic, optical, and chemical properties. Most TMD bulk crystals are van der Waals solids with strong bonding within the plane but weak interlayer bonding. The individual layers can be readily isolated. Single layer TMDs possess intriguing properties that are ideal for both fundamental and technologically...

physical and mechanical properties of alfalfa (medicago sativa, l.) grind are required for optimum design of equipment used in transporting, processing and storage of the material. this study was conducted to determine the effect of particle size (2.38, 3.36 and 4.76 mm) and moisture content (8, 9.3 and 11% wb) on some physical and mechanical properties of alfalfa grind. these properties includ...

smp was substituted by wpc in four levels for preparing reconstituted milk. two ropy and one nonropy starter cultures was used for doogh preparation. yield stress, viscosity, consistency index and pseudoplastic behavior of doogh increased by increasing wpc content. results showed that wpc increased colloidal particles dimension and constructed a network which led to a decrease in doogh phase se...

introduction: the old age is one of the vulnerable classes of people in every society. the most important issue concerning the improvement of health and quality of life of the old age deals with preservation of a high degree of their independence in physical activities and continuation of an active life. the present research aimed at comparing the effect of two types of physical activity in wat...

In this study, physical vapor deposition (PVD) Ti-Cr-N coatings were deposited at two different temperatures 100 and 400ºC on hardened and tempered tool steel substrates. The influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and Young’s modulus were evaluated. Phase compositions were st...

Many factors influence physical properties of edible composite films fabricated from hydrocolloids and lipids. Novel edible emulsified films were made using PGP, glycerol and stearic (SA) or oleic (OA) fatty acids by Tween-80 addition and emulsification of filmogenic solutions. In this study, the effect of physical state of fatty acids on the pistachio globulin protein (PGP) edible film prop...

bonding to dentin is a promising property, which can prevent leakage and improve the sealing ability of endodontic filling materials. resilon was developed and recommended initially because the existing root canal filling materials did not bond to root canal dentin. since its introduction in 2004, numerous reports have been published regarding various aspects of this material. this article aime...
