The article proposes and substantiates the function of predictive evaluation using criterion relative efficiency a cutting tool with microtextured rake surface based on tangential force temperature. Comprehensive durability tests carried out under various processing modes measurement heat power parameters made it possible to create an experimental base for mathematical modeling. An empirical mo...

Grit blasting and laser processing are two common methods used for surface microtexturing to enhance coating adhesion strength. This paper reports a thermomechanical method of Al 7075 alloy using nanosecond pulsed generate large increase in area. The entire area the substrate was microtextured melting, ablation, resolidification. morphology consisted tightly packed pillar-like features. microte...

Liquid-embedded elastomer electronics have recently attracted much attention as key elements of highly deformable and "soft" electromechanical systems. Many of these fluid-elastomer composites utilize liquid metal alloys because of their high conductivities and inherent compliance. Understanding how these alloys interface with surfaces of various composition and texture is critical to the devel...

Superhydrophobic surfaces are surfaces with fluid contact angles larger than 150o. Superhydrophobicity can be achieved by chemically modifying the surface or introducing texturing which increases the real or effective area of the surface. In this work we focus on the latter approach. If the texturing leads to a Cassie nonwetting state, the surface can also exhibit drag reduction characteristics...

The aim of this paper is to describe the possibility of achieving super-hydrophobic materials by tailoring their surface topography. Water droplets easily slip or roll down on such surfaces. However, it is found that microtextures on a solid can generate sticky surfaces as well, and the conditions for avoiding such an effect are discussed. 1. Adhesive properties of drops When a drop is deposite...

Objectives Evaluate the effects of two different machined-collar lengths and designs on peri-implant healing. Material Methods An implant with a microtextured surface 3.6mm-long internal-connection machined collar was compared to implants that had an identical 1.2mm-long external-connection collar, but one while other's machined. Participants received three implants, microgap at crest, alternat...

The first molded gas chromatography (GC) microcolumn is described. This microcolumn consists of a single microtextured thermoset polymer composite which acts as both the structural material and the stationary phase. The resultant microcolumn is inexpensive and has been coupled to a disposable colorimetric sensor array, creating a disposable column-detector unit and demonstrating a proof of conc...

Delivery of therapeutics into skin is hindered by the epidermal barriers. To overcome these barriers for the treatment of skin diseases, a cutaneous delivery method capable of field treatment using silica-elongated microparticles is developed. The microparticles are massaged into the skin using a 3D-printed microtextured applicator resulting in significant field-directed drug delivery enhancement.

We present a method to produce micropatterns of cells on tissue culture substrates. A network of deep elastomeric microchannels defining the desired pattern is sealed onto the surface of interest, and a protein template is created by injecting sub-milliliter quantities of protein solution into the microchannels. Protein adsorbs only on the areas that were exposed to the microflow. After the cha...
