Abstract: The efficacy in the use of probiotics is compromised due to their lack of survivability in gastric conditions (pH 1.5-3), leading to a large reduction in viable probiotic cells. The present disclosure describes cellulose nanocrystals (CNCs) modified with ferulic acid (FA) and shellac (SH) to produce two types of new coating materials, which are environment friendly and harmless to humans. These coating materials were developed and utilized to formulate Pickering emulsions (W1/O/W2 and W/O) for probiotic encapsulation. Based on their pKa values, greater than pKa, carboxyl groups from the CNCFA and CNCSH based Pickering emulsions were deprotonated, inducing phase separation and allow yeast releasing. This system could be further investigated for functionalized food-based applications to deliver active substances, such as probiotics, at high pH. Such delivery systems can be applied to human, animal, and aquatic systems.

Abstract: A method is provided for determining optimal values of significant process parameters in an additive manufacturing (AM) process for printing a part from a specified process material. The method involves defining a set of target output material properties to be optimized and identifying an initial set of process parameters pertaining to the AM process. The method broadly comprises a screening phase and an optimization phase. The screening phase involves generating and executing a first experiment design, and determining, based on a first output response, a subset of significant process parameters that affect the target output material properties. The optimization phase involves generating and executing a second experiment design, and determining, based on a second output response, optimal values for the significant process parameters that maximize or minimize the target output material properties.

Abstract: A monocular camera system for a vehicle includes a front mono camera, a side mono camera, and one or more controllers in electronic communication with the front mono camera and the side mono camera. The one or more controllers execute instructions to determine an ideal lagged distance the vehicle travels between a current time step and a previous time step as two asynchronous camera frames are captured by the front mono camera and the side mono camera, determine a number of delayed frames captured by either the front mono camera or the side mono camera between the current time step and the previous time step based on the ideal lagged distance. The controllers determine a direction of travel of the vehicle that indicates which mono camera is selected to provide a previous camera frame captured at the previous time step.

Abstract: This invention is related to a new treatment process employed during preparation of the ZnO ETL in a QDLED. The treatment involves exposing the ZnO layer to fluorine (F). In embodiments of this invention, the exposure of the ZnO layer to the F is performed using a fluorine plasma environment (e.g., using CF4, CHF3, C4F8 or SF6). Alternatively, the F exposure may be done by exposing the ZnO ETL to a suitable fluorine-containing substance such as fluorine gas or fluorinated solvents. The F plasma treatment of the ZnO improves both QDLED device EQE and EL stability.
