Optical Property of Some Powdered Materials

Investigation of Optical Property of Tetragonal BiFeO3

  ing the full potential linearized augmented plan wave in framework density functional theory(DFT) with wien2k code. The band structure and energy gap of the bulk structures are calculated with GGA-PBE, GGA+U and GGA+MBJ approximations, and results obtained from the MBJ function are more consistent with the reported experimental results. The optical properties such as real and imaginary parts...

Some results of semilocally simply connected property

If we consider some special conditions, we can assume fundamental group of a topological space as a new topological space. In this paper, we will present a number of theorems in topological fundamental group related to semilocally simply connected property for a topological space.

Optical Properties and Some Applications of Plasmonic Heterogeneous Materials

Rapid consolidation of powdered materials by induction hot pressing.

A rapid hot press system in which the heat is supplied by RF induction to rapidly consolidate thermoelectric materials is described. Use of RF induction heating enables rapid heating and consolidation of powdered materials over a wide temperature range. Such rapid consolidation in nanomaterials is typically performed by spark plasma sintering (SPS) which can be much more expensive. Details of t...

Kinetic Uptake Studies of Powdered Materials in Solution

Challenges exist for the study of time dependent sorption processes for heterogeneous systems, especially in the case of dispersed nanomaterials in solvents or solutions because they are not well suited to conventional batch kinetic experiments. In this study, a comparison of batch versus a one-pot setup in two variable configurations was evaluated for the study of uptake kinetics in heterogene...
