The further development of all-solid-state batteries is still limited by the understanding/engineering of the interfaces formed upon cycling. Here, we correlate the morphological, chemical, and electrical changes of the surface of thin-film devices with Al negative electrodes. The stable Al-Li-O alloy formed at the stress-free surface of the electrode causes rapid capacity fade, from 48.0 to 41...

Microfabricated field emission arrays (FEA) can be used to make flat panel displays (FPD) with high brightness, large viewing angle and high luminous efficiency. However, the current implementations of field emission displays (FED) require a trade-off between luminous efficiency and display resolution, which arises because of the structural / materials limitations and the consequent danger of d...

The contact between the polymer active layer and the electrode is one the most critical interfaces in polymer solar cells. In this article, we report the progress of interface engineering in polymer solar cell research, where the multiple functions of the interfacial materials will be discussed. The vertical composition profile in polymer:fullerene blends is an emerging topic, and the interlaye...

The cooperation between neuroscience and biomedical engineering gave rise to a recent, but growing research field, known as neuroengineering. We follow its principles to have a system providing basic descriptions of the visual world to the brain’s cortex. We describe a set of software and hardware tools to interface with neural tissue, in order to transmit visual information encoded into a bioi...

This review considers the literature published since 1994 on microbial and enzymatic biofuel cells. Types of biofuel cell are classified according to the nature of the electrode reaction and the nature of the biochemical reactions. The performance of fuel cells is critically reviewed and a variety of possible applications is considered. The current direction of development of biofuel cells is c...

Non-invasive high-throughput and long-term monitoring of endocrine cells is important for drug research, phenotyping, tissue engineering and pre-transplantation quality control. Here we report a novel approach to obtain simultaneous long-term electrical recordings of different islet cell types using multi-electrode arrays. We implemented wavelet transforms to resolve the low signal/noise ratio ...

A novel microelectrode modification method is reported for neural electrode engineering with a flake nanostructure (nanoflake). The nanoflake-modified electrodes are fabricated by combining conventional lithography and electrochemical deposition to implement a microelectrode array (MEA) on a glass substrate. The unique geometrical properties of nanoflake sharp tips and valleys are studied by op...

Title of dissertation: MOISTURE IN MULTILAYER CERAMIC CAPACITORS Daniel Noel Donahoe, Doctor of Philosophy, 2005 Dissertation directed by: Professor Michael G. Pecht Department of Mechanical Engineering When both precious metal electrode and base metal electrode (BME) capacitors were subjected to autoclave (120 oC/100 % RH) testing, it was found that the precious metal capacitors aged according...

Interleaved ionization electrode geometries offer the possibility of efficient rejection of near-surface events. The CDMS collaboration has recently implemented this interleaved approach for the charge and phonon readout for our germanium detectors. During a recent engineering run, the detectors were found to lose ionization stability quickly. This paper summarizes studies done in order to dete...
