In the present study, HRTEM micrograph of one-bi-layer and two-bi-layer of Ni/Ti thin film was investigated. Ni/Ti thin film was deposited with the help of DC/RF magnetron sputtering technique by layer-wise deposition of Ni and Ti on Si(100) substrate in the order of Ni as the bottom layer and Ti as the top layer. Four types of bi-layers are formed by varying the deposition time from 15 min to 30 min. The deposition of these amorphous asdeposited thin films were followed by annealing fro...

The interfaces of composite materials play an important role to sustain the structural integrity of the system. It has only been during the last few decades that applications of FRPs have become so rapidly growing that tailoring the well-bonded and durable interfaces has become a curious concern. An uncontrolled and non-uniform degradation at micro- and macro-levels manifests in the interphase because of different environmental conditions during service life. These may restrain its uses in th...

Changes in physicochemical properties of fresh cut tender jackfruit during storage can be related to change in its colour as well. Colorimeter measurements are best for the samples with homogeneous colour. However, for samples with non-homogenous colors or large sizes (like fruits and vegetables), the colorimeters are inappropriate and inaccurate. The aim for this study to quantify the amount of browning in fresh cut tender jackfruit slices by using image analysis technique and justify the re...

In this paper we propose a non-uniform quantization technique for reporting the test statistics computed by local cognitive radio (CR) sensors to the fusion center. Local CR sensors are assumed to compute the test statistics based on conventional energy detection technique and fusion center on accumulating the respective test statistics makes final decision about presence or absence of primary user (PU). In order to communicate the test statistics to the fusion center over a band limited cha...

Objective: Emulsion stability is one of the vital factors that determine its food applications. In this study, carvacrol loaded emulsions were prepared through ultrasonication technique. • The Influence of concentration of the emulsifier (1%, 1.25% and 1.5%) on the emulsion formation was determined. • The effect of sonication amplitude (45%, 60% and 75%) on the emulsion formulations was investigated. • Similarly, the influence of sonication time (3 min, 6min and 12 min) on the emulsion dr...

Sohiong (Prunus nepalensis) is an underutilized fruit grown in Meghalaya, India. It is very perishable and is a rich source of β-carotene, anthocyanins, phenols and antioxidants. Lack of storage facilities and processing machinery leads to minimum utilization of the fruit. Converting the fruit in to value added products will help in increasing the popularization of the fruit in domestic and international markets. Sohiong fruit has high amount of pectin, hence extracting the juice from the fru...
