Study of the fabrication of AISI 316L microneedle arrays

Description: Article describes a study in which a micro milling process was used to manufacture AISI 316L stainless steel needles arrays with a conical geometry (i.e., a base diameter and height of 1 mm by 1 mm, respectively), and an analysis of tool wear on ball nose micro end milling tools with a diameter of ~200 μm was performed to evaluate the use of lubricant in the manufacture of those conical surfaces.

Algorithmically Optimized Hemispherical Dome as a Secondary Optical Element for the Fresnel Lens Solar Concentrator

Description: This article focuses on a way to maximize the concentration acceptance product (CAP), while using the minimum SOE and receiver geometry at a given f-number and incidence angle (also referred to as the tracking error angle). The laws of polychromatic light refraction along with trigonometry and spherical geometry were utilized to optimize the POE grooves, SOE radius, receiver size, and SOE–receiver spacing.
