Abstract: Catalyst systems useful in ring-opening polymerization of β-butyrolactone to produce syndiotactic PHB are provided. The catalyst systems include a ligand of the structural Formula I, Formula II, or Formula III and a Group 3 metal or metal precursor such as yttrium. The present catalyst systems are useful in adjusting syndiotacticity and thereby lowering the Tm of PHB for use in commercial applications.

Abstract: A method of analyzing a lubricating oil may include: measuring a first concentration of components in a lubricating oil prior to introduction into a cylinder in a two-stroke engine using x-ray fluorescence, the components comprising: sulfur and total calcium; collecting a scrape-down lubricating oil that corresponds to the lubricating oil after having been passed through the cylinder during fuel combustion of a fuel comprising 0.5 wt % or less sulfur; measuring a second concentration of the components in the scrape-down lubricating oil using the x-ray fluorescence; and calculating an amount of acid neutralized during combustion based on the first and second concentration of the components. Based on said analysis a change to a property of the scrape-down lubricating oil and/or changing a feed rate of the lubricating oil into the cylinder based on the amount of acid neutralized may be implemented.

Abstract: Ceramic monolith compositions are provided with improved stability under reaction conditions involving elevated temperatures. Such monoliths can be used, for example, in reverse flow reactors under high temperature reforming conditions, where the interior components of the reaction zone can be exposed to average temperatures of 1000° C. or higher while also being exposed to rapid oscillations in temperature of 100° C. or more in the presence of alternating oxidizing and reducing chemistries. The ceramic monolith compositions can be composed of materials that have improved ability to withstand conditions in severe reaction environments. Additionally or alternately, the ceramic monolith compositions can have structural features that reduce or minimize the tendency for the monolith to suffer structural failure under the conditions in severe reaction environments.

Abstract: Velocity tomography using time lags of wave equation migration is disclosed. Seismic tomography is a technique for imaging the subsurface of the Earth with seismic waves by generated a migration velocity model from a multitude of observations using combinations of source and receiver locations. The migration velocity model may be updated in order to reduce depth differences of reflection events (also called residual depth errors (RDE)). Direct measurement of RDE may be difficult in certain complex subsurface areas. In such areas, the RDE may be reconstructed based on time lags of wave equation migration and then used to update the migration velocity model. In particular, the RDE may be directly reconstructed from the time lags of wave equation migration, such as based on a direct relation between RDE and the time lags.

Abstract: Catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer can correspond to a thermally stable metal oxide support layer, such as a metal oxide support layer that is thermally phase stable at temperatures of 800° C. to 1600° C. The catalyst systems can be beneficial for use in cyclical reaction environments, such as reverse flow reactors or other types of reactors that are operated using flows in opposing directions and different times within a reaction cycle.

Abstract: Ranking materials for post combustion carbon capture by characterizing sorbent materials with a molecular model workflow that generates microscopic figures of merit for materials by microscopic properties; and evaluating the materials from the molecular model workflow with a process model workflow that generates macroscopic figures of merit for process steps of a carbon recovery process. The materials for applicability as a sorbent material are ranked using a combined microscopic performance and macroscopic process feasibility generator that ranks the materials according to the microscopic figures of merit for materials and the macroscopic figures of merit for the process steps.

Abstract: Systems and methods are provided for integrating direct air capture of carbon dioxide with capture of carbon dioxide from a point source. The systems and methods can include exposing an adsorbent to a low CO2 content gas flow (e.g., air) at conditions similar to ambient conditions to perform an initial amount of sorption of CO2. The initial sorption results in a partially loaded sorbent having a first sorbent loading. The partially loaded sorbent can then be exposed to a flue gas and/or other gas flow that contains a higher CO2 content. This allows a second sorption step to be performed using a higher CO2 content gas, resulting in an additionally loaded sorbent having a second (higher) sorbent loading. The sorbed CO2 can then be desorbed from the sorbent.
