Optical gain and resistance against photo-bleaching are key material parameters for practical applications in microlasers microphotonics. Here, we present studies of optical amplification a wide range materials, including fluorescent dyes, quantum dots rods, organic inorganic room temperature polaritons, nanodiamonds with emission from 430 to 680 nm. We used amplified spontaneous (ASE) each mea...

The use of lithium metal as the negative electrode holds great promise for high energy density solid-state batteries (SSBs) future, but at same time presents major technical challenges in their development. Li metal, with its reactivity, soft and ductile nature, propensity towards mechanical deformation during electrochemical cycling, is susceptible to formation various defects such voids, crac...

A complex unit gain graph ( T -gain graph) Φ = G , φ ) is a where the function assigns number to each orientation of an edge and its inverse assigned opposite orientation. balanced if product gains oriented cycle (if any) 1. We propose two notions distance matrices D < max min Φ, for any ordering ‘<’ vertex set. characterize graphs which are independent ordering. show holds standard vertices on...

long–term stability and oxidation resistance of aisi 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. in this study the pack cementation method was employed to coat aisi 439 ferritic stainless steel with manganese. isothermal oxidation was conducted at 800 ºc for 200 hours in static air to investigate the role of coatin...

osmotic dehydration, as a minimal processing method, has found increasingly wide prospects during the past few decades. this process involves mass transfer which is commonly modeled by applications of different procedures, mostly based on fick's law. in this research, we approached the modeling process by first obtaining experimental measurement of potato’s solid gain, water loss and moisture c...
