Surface functionalization with organic molecules has proven effective to modulate the electronic properties of 2D materials. More recently, surface been shown induce magnetic behaviors in nonmagnetic If magnetism can be imparted materials via by tailored properties, it would make available whole spectrum as systems, which are currently limited a small subset that intrinsically magnetic. This pe...
Thermal property is the important material property for engineering and analysis of insulating materials. In this study, thermal conductivities of insulating materials are determined and compared with the literature values. Lee’s and Charlton’s apparatus is used to measure this property of insulating materials by steady state technique. This apparatus gives more precise result for insulators th...
The design of online course materials needs to balance intellectual property protection with the use of the materials. This article describes an evaluation of online lessons produced as HTML pages using two different versions of the Microsoft PowerPoint software. A survey conducted of participants using these materials revealed a number of positive outcomes including a high level of satisfactio...
The wide range of properties covered by the manufacturable fiber–matrix combinations of composite materials, along with their directional property characteristics, provides designers with material selection flexibility during designing composite material products. Meeting multiple property goals, however, complicates the design process as both the composite material selection and the component ...
A signi®cant breakthrough has been achieved using materials databases, semi-empirical methods and neural networks to aid in the design of new materials. A collaborative, international, team discovered that a non-linear expression involving one elemental property parameter could be used to predict, with 99+% accuracy, the occurrence of a compound for any ternary materials system. This elemental ...
