Abstract
This invention relates to improved cellulose nanocrystal fillers for rubber compositions and more specifically with the grafting of disulfide and thioesters onto cellulose nanocrystals for improved performance as a filler in rubber compositions. At least one embodiment describes a method to graft thiols or disulfides on CNC surfaces via esterification exemplified by 3-mercapto-propionic acid (MPA), 3-(acetylthio) propionic acid (APA), or dithiodipronanoic acid (DTDPA). The reaction may be carried out on CNCs highly dispersed in a suitable solvent and improved reaction conditions to achieve a favorable degree of substitution, DS. The embodiment further discloses how surface thiol groups can then be protected, in a second step, as thioesters or asymmetric disulfides to tune the hydrophobicity of CNCs to improve compatibility with styrene-butadiene, SBR, or natural rubbers.

Abstract
A system (100) installed in a mining truck (10) implements a method for detecting acoustic events related to phases of a cycle of the mining truck, such that each acoustic event is characterized by an acoustic signature allowing periods of loading and of unloading and periods of driving loaded and empty to be identified from the amplitude and frequency of the recordings. A method (200) detects acoustic events denoting phases of a cycle of the mining truck. A mining truck has a module for executing an analyzing application for analyzing one or more signals indicative of acoustic events in order to determine whether the mining truck is in the course of a mining cycle and to determine the current phase of the mining cycle being executed by the mining truck.

The alternating electrical field is capable of alternately projecting all or some of the components of the mixture that is present in the receptacle towards or against the first electrode and then towards or against the second electrode in order to generate mechanical impacts on the components that contribute to breaking down the mixture within the receptacle and in order to facilitate the passage of components belonging to the second family through the screen. The screen ensures components belonging to the first family are retained in the receptacle.
