    Abstract: Methods of controlling crystal polymorphism in organic-free synthesis of Na-Zeolites and the zeolite crystals formed using those methods are provided. The methods disclosed herein create certain types of zeolite crystals more efficiently than other previously known methods. The methods also create certain types of zeolite crystals in a form and concentration not previously disclosed. The methods disclosed herein generally comprise using solutions with varying ratios of silicon (Si), aluminum (Al), hydroxide (OH), and water. Some implementations of the invention disclosed include efficient methods of producing nearly pure cancrinite (CAN), methods of obtaining sodalite in solutions with a high Si/Al ratio, and a method of forming thin, platelet-like ANA crystals with a width of less than about 1 μm and a length of at least about 3 μm.

    Abstract: An excitation force (internal or external) and phase-sensitive optical coherence elastography (OCE) system, used in conjunction with a data analyzing algorithm, is capable of measuring and quantifying biomechanical parameters of tissues in situ and in vivo. The method was approbated and demonstrated on an example of the system that combines a pulsed ultrasound system capable of producing an acoustic radiation force on the crystalline lens surface and a phase-sensitive optical coherence tomography (OCT) system for measuring the lens displacement caused by the acoustic radiation force. The method allows noninvasive and nondestructive quantification of tissue mechanical properties. The noninvasive measurement method also utilizes phase-stabilized swept source optical coherence elastography (PhS-SSOCE) to distinguish between tissue stiffness, such as that attributable to disease, and effects on measured stiffness that result from external factors, such as pressure applied to the tissue. Preferably, the method is used to detect tissue stiffness and to evaluate the presence of its stiffness even if it is affected by other factors such as intraocular pressure (IOP) in the case of cornea, sclera, or the lens. This noninvasive method can evaluate the biomechanical properties of the tissues in vivo for detecting the onset and progression of degenerative or other diseases (such as keratoconus).

    Abstract: A system and method for matrix assisted laser desorption time-of-flight (MALDI-TOF) mass spectrometry. A method for MALDI-TOF mass spectrometry includes initiating a spectral analysis of a sample on a MALDI-TOF spectrometer. The sample is ionized, and a first ion spectrum is detected and stored. Thereafter, the spectrometer is reset, and the ionizing, detecting, storing, and resetting are repeated until a predetermined plurality of spectra of the sample is acquired.

    Abstract: A method and apparatus is provided for obtaining a low average electron energy flux onto a substrate in a processing chamber. A processing chamber includes a substrate support therein for chemical processing. An energy source induced plasma, and ion propelling means, directs energetic plasma electrons toward the substrate support. A dipole ring magnet field is applied perpendicular to the direction of ion travel, to effectively prevent electrons above an acceptable maximum energy level from reaching the substrate holder. Rotation of the dipole magnetic field reduces electron non-uniformities.

    Abstract: A design of a quantum well region that allows faster and more efficient carrier collection in quantum well solar cells. It is shown that for a quantum well material system displaying a negligible valence band offset, the conduction band confinement energies and barrier thicknesses can be designed to favor a sequential thermionic promotion and resonant tunneling of electrons to the conduction band continuum resulting in faster carrier collection rates than for a conventional design. An evaluation of the proposed design in the context of devices incorporating GaAs/GaAsN quantum wells shows a collection of all photo-generated carriers within several to tenths of ps (10−12 s) from deep quantum wells rather than several ns, as it is the case for conventional designs. The incorporation of the proposed design in single and multijunction solar cells is evaluated with efficiency enhancements.
