In the last few years, an increase in interest has been given to the use of cellulose fibers as alternatives for conventional reinforcements in composites.
Over the past five decades, paramount interest had been given to the synthesis of single crystals for use as scintillators in nuclear radiation detection field.
In recent years, increased research interest has been given to self-organizing wireless networks in which mobile devices allocate resources in a decentralized manner [5].
Thus, a lot of interest has been given in the use of gas working fluids in PTC, as air, nitrogen, helium and carbon dioxide.
In recent years, considerable interest has been given to develop biologically active antibacterial scaffolds which are similar analogs of the extracellular matrix (ECM) that have induced synthesis of tissues and organs.
Considerable interest has been given to forming an international collaboration to develop a virtual moderate spatial resolution land observation constellation through aggregation of data sets from comparable national observatories such as the US Landsat, the Indian ResourceSat and related systems.
For instance, a growing interest has been given to the link between Second Language Acquisition (SLA) and language assessment (Bachman & Cohen 1998; Chalhoub-Deville 2003; Douglas & Selinker 1985; Lantolf 2009; Leung 2007).
Thus, during present days, intense interest has been given in the biomedical field of tissue engineering wherein several new biomaterials are constructs in the form of scaffold (i.e., polymeric material, bioceramics, biocomposites) can be implanted in patients to replace failing or malfunctioning organs (Mano et al. 2007).
Much more interest has been given to TCOs based on ZnO such as undoped ZnO thin films [4], Al-doped ZnO (AZO) thin films [5], and Ga-doped ZnO (GZO) thin films [6] due to their stability under hydrogen plasma which makes them a potential candidate for solar cells' technology based on thin-film silicon.
