Influence of phase transformation on the micromachinability of laser powder bed fused Inconel 718

open access: yesScientific Reports
The characteristics of laser powder bed fusion (L-PBF) Inconel-718 (IN-718) differ from those of its wrought counterpart because of the rapid heating and cooling cycles involved during the process.

New Approach to High-Speed Multi-Coordinate Milling Based on Kinematic Cutting Parameters and Acoustic Signals

open access: yesJournal of Manufacturing and Materials Processing
In this work, a new approach to high-speed multi-coordinate milling was developed. The new approach is based on a new model of trochoidal machining; this is, in turn, based on the theoretical thickness of a chip and its ratio to the cutting edge’s radius,

Artificial dielectric devices for variable polarization compensation at millimeter and submillimeter wavelengths [PDF]

open access: yes, 2003
Variable polarization compensation has been demonstrated at 100 GHz. The device consists of two interlocking V-groove artificial dielectric gratings that produce a birefringence that varies with the separation distance. A maximum retardance of 74/spl deg/

Laser surface texturing of a WC-CoNi cemented carbide grade: surface topography design for honing application [PDF]

open access: yes, 2018
Abrasive effectiveness of composite-like honing stones is related to the intrinsic surface topography resulting from the cubic boron nitride (CBN) grains protruding out of the metallic matrix.

Single Solid‐State Ion Channels as Potentiometric Nanosensors

open access: yesAdvanced Functional Materials, EarlyView.
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

High-speed Fabrication of Micro-channels using Line-based Laser Induced Plasma Micromachining (L-LIPMM) [PDF]

open access: yes, 2013
Micro-texturing of surfaces has various applications that often involve texturing over large (macro-scale) areas with high precision and resolution. This demands scalability and speed of texturing while retaining feature sizes on the order of a few ?m.
