Taha-Tijerina, in collaboration with researchers Tharangattu Narayanan, Pulickel M. Ajayan, et al., prepared a nano-based transformer oil using hexagonal boron nitride. Hexagonal boron nitride, which was prepared by a liquid exfoliation process, exhibits good electric insulation properties in combination with good thermal conductance. It was sonicated in isopropyl alcohol at room temperature, centrifuged, and filtered of the supernatant liquid. The two-dimensional hexagonal boron nitride flakes provide a percolation channel that facilitates movement of electrons. No surfactant is needed to stabilize the dispersion, which could decrease the thermal conductivity by inhibiting electron flow. The hexagonal boron nitride-based transformer oil also shows a stable zeta-potential value of 22 mv, indicating the stability of the dispersion. Source

A new ion-conducting membrane (ICM) was developed that can stop the growth of dendrites, increasing the possibility of producing safer lithium-ion batteries. The nanocomposite material was prepared from aramid nanofibers (ANF) and poly( ethylene oxide)(PEO). The PEO/ANF films were uniform with diameters that were ≯ 20 nm. The PEO/ ANF film showed the right property profile to stop the growth of dendrites. Further work with lithium-ion battery cells showed that the voltage profile remained steady ≤ 2500 cycles conducted. In contrast, a battery prepared with a commonly used ICM exhibited a slowly deteriorating voltage profile from the lst cycle to the 2500th cycle. This decline was due to the formation of dendrites.

Increasing the efficiency of automobiles and heavy-duty vehicles is becoming paramount with the rising cost of fuel. The search for ways to improve the efficiency of automobiles and heavy-duty diesel vehicles has moved beyond just focusing on engine design and changing the characteristics of the automotive lubricant. A discussion covers the possibility of recycling heat generated during combustion and turning it into electricity; wasted fuel energy produced during combustion; use of exhaust-based thermoelectric generators that can convert heat to electricity; concerns on pollutants in the exhaust process; thermoelectric materials and their conversion efficiencies; and the use of thermoelectric materials to extract more energy out of the combustion process.

In formulating product, lubricant suppliers always focus on meeting customers' needs. As the need grows to have lubricants function under more stressful operating conditions, the challenge persists to develop a value-added product that can provide excellent performance over a long operating time frame. An additive that is becoming more important to the formulator in meeting this goal is the Viscosity Index (VI) improver. This additive class helps lubricants work at high performance levels over a wide temperature range. A discussion on VI improvers covers their preparation; key functions; how to measure VI performance; applications, e.g., as engine oils and hydraulic fluids; obtaining the maximum value out of VI improvers; formulation of multigrade lubricants; thickening effect at high temperatures; oxidative stability, which is a factor in ensuring that the viscosity remains relatively stable; polymer properties affecting VI improvers; modifying the structure of a VI improver to optimize lubricant performance; VI and driveline fluids; and VI and hydraulic fluids.

In the Boudouard reaction, carbon reacts with CO2 to form CO at extremely high temperatures. Better utilization of the Boudouard reaction in commercial applications can only occur if the temperature is reduced. One potential option is the use of microwave radiation. Microwaves have been found to selectively heat carbon, leading to a dramatic change in the thermodynamics of the reaction. As a result, the enthalpy and entropy of the Boudouard reaction decline, pushing the reaction to the right and leading to higher conversions of CO at lower temperatures. Professor Albert Stiegman of Florida State University in Tallahassee, FL, and his fellow researchers have determined that microwave heating can reduce the activation energy so that CO becomes the major product formed at significantly lower temperatures. In particular, CO conversion > 90% can be achieved at 419°C when using microwaves as compared to 763°C using convective heat. Source
