Comparative study on phase changing material for refrigeration effect for milk chilling
Provedor de dados: 111
Autores: Sharma, Amandeep; Gupta, Silvy; Kaur, Kulwinder.
 In developed countries the milking collection is done to process in various diary plants situated far away from production areas.  There is a problem of cool chain management, which, generally is absent at farm levels.  To manage the cool chain in milk transportation system right from farm level it is required that some locally available techniques/materials should be selected and used for milk chilling.  The objective of current study is to ascertain mechanism for chilling of milk at farm immediately after milking.  The experiments were conducted and the cooling performance was evaluated by noting down the drop in temperature with respect to time using mercury thermometer.  The respective regression equation and R2 value were obtained for every run of...

Unraveling the Role of Π - Conjugation in Thiophene Oligomers for Optoelectronic Properties by DFT/TDDFT Approach
Provedor de dados: 52
Autores: Gajalakshmi,; Tamilmani,V.
ABSTRACT Thiophene oligomer has been investigated using DFT/TDDFT calculations with an aim to check its suitability for opto electronic applications and also to analyse the influence of π-bridge. Our results revealed that thiophene oligomers have excellent π-conjugation throughout. FMO analysis give an estimate of band gap of thiophene oligomer and further revealed HOMO are localized on π - bridge, donor group and LUMO are localized on π - bridge and acceptor group. A TDDFT calculation has been performed to understand the absorption properties of them in gas phase and solvent phase. PCM calculations convey that absorption maxima show positive solvatochromism. Among the designed candidates, the one with more π - bridge show higher wavelength of absorption...
