Nanoscale roughness micromilled silica evanescent refractometer

Optics Express, 2015
We demonstrate machining of precision slots in silica with nanoscale roughness for applications in photonics. Using our in-house developed milling system we have achieved machined slots with surface roughness of 3.0 nm (Sa) and 17 µm depth of cut. This result represents eight times improvement in surface roughness and forty times increase in depth of ...

Methods to estimate marine functional connectivity: A primer

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Micromilling for Mold Fabrication

, 2003
A method for manufacturing a new type of CMP pad is presented. The goal is to create a mold containing micro sized features that can be used in vacuum casting to produce the polymeric polishing pads. To achieve this, a positive mold is cut from PMMA using micro milling techniques.

Investigating the transition from ploughing to shearing in micromilling of additively manufactured Ti6Al4V [PDF]

Nanotechnology and Precision Engineering
Compared with wrought Ti6Al4V, additively manufactured (AM) Ti6Al4V exhibits more severe machining difficulties owing to its lower thermal conductivity and higher hardness.
