Evidence of Trap Distribution in Borate Glass

Abstract

In order to elucidate the type of trap distribution in borate glass we have analyzed a set of glow peaks around 110°C recorded with different doses of β-ray irradiation. The glow curves are subjected to the rigorous Computerized Glow Curve Deconvolution (CGCD) both in the framework of kinetic formalism and differential equation formalism to judge which type of trap distribution favors in borate glass. It is observed that the distribution of traps is exponential, which is also well supported by standard error analyses i.e. Figure Of Merit (FOM) and Chi-square (χ2) test.

Estimation of thermally stimulated current in as grown TlGaSeS layered single crystals by multilayered perceptron neural network

“…The TSC spectra decrease in intensity and shifts towards higher temperatures with increase in the light excitation temperature. This fact supports the validity of a quasi-continuous trap distribution (Anedda et al, 1997;Bosacchi, Bosacchi, Franchia, & Hernandez, 1973;Ricci, Anedda, Corpino, Tiginyanu, & Ursaki, 2003;Schafferhans et al, 2008;Serpi, 1976;Singh, Sharma, & Singh, 2006).…”

Synthesis and Characterization of Carboxymethylated Locust Bean Gum‐co‐poly(SA)‐cl‐poly(MBA) pH Responsive Hydrogel for Controlled Drug Delivery of Metformin Hydrochloride

“…It has been observed from Figure 1b and 1c, that the pH and temperature of the swelling medium affect the hydrogels′ potential to swell. The constituted ions (COO − ) formed at higher pH in the matrix material during partial hydrolysis may be the cause of this ionic repulsion and thus cause the opening of the pores in the polymeric web [24,25] . Swelling of the hydrogel correlated with the release of the drug.…”

Advances in Injectable and Self‐healing Polysaccharide Hydrogel Based on the Schiff Base Reaction

“…In recent years, the polysaccharides have become ideal materials to prepare the self-healing hydrogels containing imine or acylhydrazone bonds because their backbones carry a large number of functional groups that can partake in the Schiff base reaction either in a direct way (such as the primary amine groups of chitosan) or after being modified into aldehyde and amine groups. [36][37][38][39][40] The polysaccharide hydrogels prepared by the Schiff base reaction share all advantages mentioned above for the self-healing hydrogels such as injectability, self-mending properties, and good biocompatibility, and have been broadly used in the fields of drug delivery and cell culture, offering an ideal minimally non-invasive treatments on cancer, cardiovascular and neurological diseases. [16,41,42] Besides, the polysaccharides are abundant in animals, plants, or micro-organisms so their source is much easier and wider compared to other natural or synthetic polymers used for the hydrogel, which greatly facilitates the development of the polysaccharide-based self-healing hydrogels.…”
