We use lithium carbonate and titanium dioxide for this purpose. And a different percentage of vanadium pentoxide is used. The structural properties of the material are studied. LTO has an octahedral structure. XRD of the samples gives the peaks at 2θ=25O & 2θ=18. Also, the vanadium peak has appeared for the samples with a vanadium percentage of more than 2 %. It appears at the angle 2 theta = 27.5°. The electrical properties of the samples are studied. For this purpose, pellets are prepared for a size 1.2cm diameter and 0.9mm thin. The minimum resistance of the material is observed for 2% vanadium. DRS of the samples is studied and then calculated the bandgap which shows that the bandgap is reduced by doping of vanadium oxide in lithium Titanate. This shows that the conductivity of the lithium Titanate is increased by doping which also enhanced the electrochemical properties of the material by showing stable and high rate performance during the charging-discharging of a battery.","PeriodicalId":92437,"journal":{"name":"Research & reviews.

At the time of the accident it deforms axially and absorbs accidental energy. Crash box structure provides comfort to the passenger at the time of impact. It works as safe guard for the costly components behind the bumper like engine hood and cooling system. In this report plane crash box geometry is studied for the energy absorption. Study is based on analytical, experimental and numerical work. Various parameters like width, thickness, filler material which affects the crash box performance are studied by using Design of experiments. In this experiment we will be using ABAQUS CAE as a modelling and analysis software.","PeriodicalId":92437,"journal":{"name":"Research & reviews.

These communities can build up in a variety of different environments from industrial equipment to medical devices resulting in damage, loss of productivity and disease. They also have great potential for economic and societal benefits as bioremediation agents and renewable energy sources. The great potential benefits and threats of biofilms has encouraged researchers across disciplines to study biofilm characteristics and antibiofilm strategies resulting in chemists, physicists, material scientists, and engineers, to develop beneficial biofilm applications and prevention methods. The ultimate outcome is a wealth of knowledge and innovative technology. However, without extensive formal training in microbes and biofilm research, these scientists find a daunting array of established techniques for growing, quantifying and characterizing biofilms while trying to design experiments and develop innovative laboratory protocols. This mini-review focuses on enriching interdisciplinary efforts and understanding by overviewing a variety of quantitative and qualitative biofilm characterization methods to assist the novice researcher in assay selection. This review consists of four parts. Part 1 is a brief overview of biofilms and the unique properties that demand a highly interdisciplinary approach. Part 2 describes the classical quantification techniques including colony forming unit (CFU) counting and crystal violet staining, but also introduces some modern methods including ATP bioluminescence and quartz crystal microbalance. Part 3 focuses on the characterization of biofilm morphology and chemistry including scanning electron microscopy and spectroscopic methods. Finally, Part 4 illustrates the use of software, including ImageJ and predictive modeling platforms, for biofilm analysis. Each section highlights the most common methods, including literature references, to help novice biofilm researchers make choices which commensurate with their study goals, budget and available equipment.</p>","PeriodicalId":92437,"journal":{"name":"Research & reviews.
