The Clear Plastic Appliance

Minimizing the cost of monitoring Pet(CO2) through a clear plastic face mask.

To the Editor:-‘Ike title “Cardiogenic failure after isolated neurologic injury: a report of two cases” by Pousman and Parmley’ caused this aging reader some anguish, realizing how slippery hath become our lexicon. Many years ago I learned about “cardiogenic shock,” which I took to mean a state of diminished tissue perfusion and oxygenation caused by a gravely diminished output from the heart. ...

The two by four appliance: a versatile appliance.

The 2 x 4 appliance comprises bonds on the maxillary incisors, bands on the first permanent maxillary molars and a continuous archwire. The appliance is used in the early mixed dentition for treatment of both anterior crossbites and alignment of ectopic incisors. Four cases using this appliance are presented. This appliance offers many advantages over alternative techniques as it provides compl...

Self-alignment techniques for fabricating a-Si:H TFTs at 300C on clear plastic

We previously demonstrated highly stable backchannel cut and back-channel passivated amorphous silicon thin-film transistors (a-Si:H TFTs) made at 300C on 2.9-inch x 2.9-inch clear plastic substrates [1]. Mechanical stress in the TFT stack causes the substrate to expand or contract, which easily results in misalignment between consecutive device layers [2,3]. Therefore we developed three selfal...

P-24: High-Temperature (250°C) Amorphous-Silicon TFT’s On Clear Plastic Substrates

Amorphous silicon (a-Si) thin film transistors (TFT’s) were fabricated on free-standing, clear plastic substrates with a maximum process temperature of up to 250°C. An a-Si TFT backplane for active matrix OLED (AMOLED) application was also made on such substrates. The performance of both the TFT’s and the AMOLED backplane are excellent. These results will enable the fabrication of flexible AMLC...
