Well shaped single crystalline Mn3O4 nano-octahedra with exposed highly active {011} facets at different particle sizes have been synthesized and used as anode materials for lithium ion batteries. The electrochemical results show that the smallest sized Mn3O4 nano-octahedra show the best cycling performance with a high initial charge capacity of 907 mA h g(-1) and a 50th charge capacity of 500 ...

is one of ten regional units mandated by Congress and established in Fall 1988 to support research, education, and training in surface trans-portation° The UC Center serves federal Region IX and is supported by matching grants from the U.S. Department of Transportation, the California Department of Transportation (Caltrans), and the University. Based on the Berkeley Campus, UCTC draws upon exis...

In this paper, we developed a versatile ionic field effect transistor (IFET) which has an ambipolar function for manipulating molecules regardless of their polarity and can be operated at a wide range of electrolytic concentrations (10(-5) M-1 M). The IFET has circular nanochannels radially covered by gate electrodes, called "all-around-gate", with an aluminum oxide (Al2O3) oxide layer of a nea...

Electrostatics is widely used in the snack food industry as an alternative to traditional powder coating. The purpose o f this study is to determine whether electrostatics improves the functionality of different food powders and to evaluate the mechanisms involved in the process. French fries were coated at 0kV and -25kV with smoke extract or glucose and mozzarella cheese slices with sodium ery...

This paper investigates how a country’s geographic position relative to other countries affects the quality of its exports. The two driving forces are the supply-side response to the specific transportation cost (generalized Alchian-Allen effect) and the stronger preference for quality in richer countries. Producers who may be unable to adjust quality for every market will choose a common quali...

The study of the battery charge process as the only power storage agent in off-grid systems is of significant importance. The battery charge process has different modes, and the battery in these modes is dependent on the amount of charge. In order to charge the battery in off-grid systems, two charge controllers including Pulse Width Modulation (PWM) and Maximum Power Point Tracker (MPPT) are c...

Photoelectrocatalysis The cover image, highlighting the work by Fatwa Firdaus Abdi, Yun Hau Ng, and co-workers in article number 2102023, shows photoelectrochemical water oxidation on an illuminated plate-like bismuth tungstate photoanode thin film. tungsten concentration is modulated to tune photoexcited charge transportation of This “self-doped” leads higher carrier density improved conductiv...

In this paper some research questions which potentially lie within the purview of the new discipline of Computational Transportation Science are presented. Some of these questions are no doubt old and jaded and some may rightly reside in a different research field (or be seen as engineering) but viable solutions to all of the issues presented are of vital importance to the efficacy of future tr...
