Gas sensors are described herein that are useful for selectively detecting a second gas (e.g. isoprene) in the presence of a first gas (e.g. acetone). The gas sensors include a sensor element which includes a semiconductor sensing material and a porous material. The sensor element is configured so that the porous material absorbs more of the first gas than the second gas. Thus, when the gas being analyzed, such as a mammalian (including human) breath, a greater proportion of the second gas comes into contact with the semiconductor sensing material.

Gas sensor element

A breath sensor apparatus for detecting the presence of a compound in an exhaled gas sample, the apparatus comprising a chamber for retaining a gas sample, the chamber defining a gas inlet and a gas outlet, a sensor inside the chamber for analyzing the gas sample, an airflow disrupting element disposed proximate to the sensor to affect the airflow near the device, and an airflow reducing element disposed over the gas outlet to increase the retention time of the gas sample within the chamber.

Breath sensor apparatus

An emissive construct comprising a fluorescent layer comprising a fluorescent host and a fluorescent dopant, wherein the fluorescent layer has a higher electron mobility than hole mobility; a first phosphorescent layer, comprising a first phosphorescent host and a first phosphorescent dopant, wherein the phosphorescent layer has a higher electron mobility than hole mobility; and an exciton blocking layer disposed between the fluorescent layer and the phosphorescent layer.

White organic light-emitting diode

The present disclosure relates to an emissive construct, which can be used in various OLED applications, for example, top-emission white organic light-emitting diodes. The emissive construct includes a fluorescent emissive layer, a partial hole-blocking layer, and a phosphorescent emissive. A recombination zone is shared between the fluorescent emissive layer and the phosphorescent emissive layer, such that the thickness of the partial hole-blocking layer is less than about one-third of the thickness of the recombination zone.

Top-emitting white organic light-emitting diodes having improved efficiency and stability

Polyphenylene compounds such as compounds represented by Formula 1 may be used in electronic devices such as organic light-emitting devices. For example, the compounds may be used as host materials in a light-emitting layer.

Polyphenylene host compounds

Included herein is the compound: and related compounds, and light-emitting devices comprising the same.

Compounds for use in light-emitting devices

Light-emitting devices are described herein.

Light-emitting devices comprising nanostructures

Polyphenylene compounds such as compounds represented by Formula I may be used in electronic devices such as organic light-emitting devices. For example, the compounds may be used as host materials in a light-emitting layer.

Emissive constructs having three emissive layers, each having the same fluorescent host are described. At least one of the layers further includes a phosphorescent dopant. Light-emitting devices including these emissive constructs are also described.
