A radiation detector includes a photodetector and a scintillator coupled thereto. The scintillator is formed of a scintillator material comprising an organic glass scintillator (OGS) material and at least one of a polymer additive or a plasticizer additive. The scintillator emits light when radiation is received at the scintillator, and the light is received by the photodetector. The radiation detector can further include a frame that has an interior cavity that holds the scintillator in position with respect to the photodetector, such that the light emitted by the scintillator is transmitted to the photodetector. The scintillator can be formed by casting amorphous scintillator material in the interior cavity of the frame. The frame can then be coupled to the photodetector to form the radiation detector.

Scintillator array for radiation detection

A fuel for an internal combustion engine includes a Cto Cdialkoxyalkanoate corresponding to formula (I): wherein the Rgroup is —H or a —CHgroup, the Rand R' groups are alkyl groups independently selected to have 1 to 9 carbon atoms; and the Rgroup is selected to have 1 to 9 carbon atoms. The compounds described herein may be used as neat fuels or mixed fuels (with diesel, biodiesel, jet fuel, marine fuel or other fuel compounds) in autoignition or spark ignition engines, such as diesel engines, gasoline (spark ignition) engines, MCCI, Homogeneous Charge Compression Ignition (HCCI) engines, or more generally in Low-Temperature Gasoline Combustion (LTGC) engines (using gasoline-like fuels), that have the high-efficiency advantages of HCCI but can operate with some level of charge inhomogeneities. Methods of making these compounds are environmentally friendly and can be done in a continuous manner.

A plastic scintillator includes a polymeric matrix comprising a primary fluorophore capable of forming an amorphous glass in its pure form. The primary fluorophore is also capable of generating luminescence in the presence of ionizing radiation and includes: a central species including silicon; a luminescent organic group bonded to the central species or to an optional organic linker group, the luminescent organic group including fluorene or an analog thereof; and the optional organic linker group, if present, is bonded to the central species and the luminescent organic group.

High luminescence plastic scintillators

A plastic scintillator includes a polymer matrix, an aliphatic additive present in the polymer matrix in an effective amount to impart fog resistance to the plastic scintillator, and at least one fluorescent dye in the polymer matrix, the dye being effective to provide scintillation upon exposure to radiation. The effective amount of the aliphatic additive is in a range of greater than 0 weight percent up to 5 weight percent relative to the total weight of the plastic scintillator. Moreover, the aliphatic additive has a structure comprising up to 300 repeat units.

Defect-resistant plastic scintillators with aliphatic additives

A fuel for an internal combustion engine includes a Cto Cdialkoxyalkanoate corresponding to formula (I): 

A fuel mixture includes a fuel and an octane overboosting additive. Methods of preparing and using such mixtures are disclosed. In particular, the mixture includes an additive that provides octane boosting that produces peak octane at or before a 40% blend and produces at least a 1 octane boost at 10% volume of additive to fuel mixture.

Compounds that induce octane overboosting

A plastic scintillator includes an anti-fog additive or comonomer. The plastic scintillator is formulated to resist the development of hydrothermally-induced aging defects (e.g. discoloration and 'fogging') while maintaining scintillation light output and other desirable physical properties.
