Abstract: This invention relates to a self cleaning reactor and to a process for the oligomerization of ethylene that employs a self-cleaning reactor. The reactor includes a mass of inert, particulate cleaning bodies that are entrained by the liquid in the reactor and scour the internal surfaces of the reactor during normal operation. This scouring action reduces the level of fouling on the reactor surfaces. Foulant material (polyethylene) is removed from the process on a continuous basis but the cleaning bodies remain within the reactor.

Abstract: A process for preparing an oxidative dehydrogenation catalyst or oxidative dehydrogenation catalyst precursor that includes mixing solutions of molybdenum and tellurium at a pH from about 3.3 to 7.5; adjusting the pH of the resulting solution back to about 5 and adding VOSO4 and adding a solution of Nb2O5 and oxalic acid and treating the resulting precursor slurry in a controlled pressure hydrothermal process to obtain the catalyst.

Abstract: A method and system are presented for use in scatterometry analysis for a patterned structure. According to this technique, a model of a patterned structure is provided comprising a selected number of virtual segment data pieces indicative of a respective number of segments of the patterned structure along Z-axis through the structure. Each of the segment data pieces is processed for determining a matrix [?n] comprising Z-axis derivatives of electromagnetic fields' response of the segment to incident field based on Maxwell's equations' solution, and transforming this matrix [?n] into an approximated response matrix [?n] corresponding to the electromagnetic field interaction between two different points spaced along the Z-axis. The transformation is preferably carried out by a GPU, and comprises embedding said matrix [?n] in a series expansion of said matrix exponential term [?n].

Abstract: The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.

Abstract: The invention provides compositions including epinephrine nanoparticles and methods for therapeutic use of the compositions for the treatment of conditions responsive to epinephrine such as a cardiac event or an allergic reaction, particularly anaphylaxis. The epinephrine nanoparticles can be incorporated into orally-disintegrating and fast-disintegrating tablet pharmaceutical formulations and can significantly increase the sublingual bioavailability of epinephrine, and thereby reduce the epinephrine dose required. Additionally, the invention provides methods for fabrication of stabilized epinephrine nanoparticles for use in the described compositions.

Abstract: A method and system are presented for use in optical measurements on patterned structures. The method comprises performing a number of optical measurements on a structure with a measurement spot configured to provide detection of light reflected from an illuminating spot at least partially covering at least two different regions of the structure. The measurements include detection of light reflected from said at least part of the at least two different regions comprising interference of at least two complex electric fields reflected from said at least part of the at least two different regions, and being therefore indicative of a phase response of the structure, carrying information about properties of the structure.

Abstract: A metrology system is presented for measuring parameters of a structure. The system comprises: an optical system and a control unit. The optical system is configured for detecting light reflection of incident radiation from the structure and generating measured data indicative of angular phase of the detected light components corresponding to reflections of illuminating light components having different angles of incidence. The control unit is configured for receiving and processing the measured data and generating a corresponding phase map indicative of the phase variation along at least two dimensions, and analyzing the phase map using modeled data for determining one or more parameters of the structure.

Abstract: A recyclable package such as a Stand Up Pouch (SUP) is prepared using a coextruded polyethylene structure having a first surface layer, a first intermediate layer, a second intermediate layer, and a second surface layer which is a sealable layer. The coextruded structure contains two layers of High Density Polyethylene (HDPE) to provide stiffness. The structure also contains a layer of lower density polyethylene. The structure is optionally surface printed. This structure is suitable for preparing packages for a wide variety of flowable foods (including liquids and solids).

Abstract: A test structure is presented for use in metrology measurements of a sample pattern. The test structure comprises a main pattern, and one or more auxiliary patterns. The main pattern is formed by a plurality of main features extending along a first longitudinal axis and being spaced from one another along a second lateral axis. The one or more auxiliary patterns are formed by a plurality of auxiliary features associated with at least some of the main features such that a dimension of the auxiliary feature is in a predetermined relation with a dimension of the respective main feature. This provides that a change in a dimension of the auxiliary feature from a nominal value affects a change in non-zero order diffraction response from the test structure in a predetermined optical measurement scheme, and this change is indicative of a deviation in one or more parameters of the main pattern from nominal value thereof.

Abstract: Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.

Abstract: Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins. Various embodiments of an oxidative dehydrogenation chemical complex designed to allow removal of sulfur containing contaminants that collect in the gas mixer unit and in the feed lines leading to the ODH reactor are disclosed herein.
