It is a challenge for a superhydrophobic coating to overcome the poor robustness and the rough surface structure that is usually built using inorganic particles that are difficult to degrade. In this study, a robust superhydrophobic coating is facilely prepared by using commercial biodegradable lignin-coated cellulose nanocrystal (L-CNC) particles after hydrophobic modification to build rough s...

During the routing of coarse particles in sedimentary environments, are subjected to abrasion, leading mass loss and changes particles’ morphology. The become more spherical, rounded, smooth. Here, (quarried dolomite) morphological evolution three shape aspects (form, roundness, texture) decreases obtained two sets experiments different setups presented. Abrasion were carried out cycles. Betwee...

soft-sphere discrete element method (dem) and navier-stokes equations were coupled with equations of energy for gas and solids to investigate the process of agglomeration in fluidized bed of polyethylene particles at high temperature. the newton’s second law of motion was adapted for translational and rotational motion of particles and agglomerates. the cohesive force for polyethylene particles...

Incorporating Graphene Oxide (GO) in concrete composite has been a good alternative to Pristine due its hydrophilic nature and ability readily disperse water the consequent cementitious mix. The addition of GO mix found enhance mechanical properties. This paper aims assess abrasion resistance incorporated for application road pavement design. Experiments strength terms compression, workability ...

A study was conducted to determine whether the mandibles of the detrito-/bryophagous groundhopper Tetrix tenuicornis are subject to mechanical wear as a result of feeding, as is the case for grasshoppers that feed on silica-rich grasses. Abrasion was evaluated by measuring the length and width of the 3rd incisor and length of the 4th incisor in adults of different ages collected under natural c...

Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...
