Optimizing electron backscatter diffraction of carbonate biominerals—resin type and carbon coating [PDF]

open access: yes, 2009
Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates ...

Ionic Fragmentation of Methyl Methacrylate Induced by Synchrotron Radiation and Multiphoton Ionization

open access: yesJournal of the Brazilian Chemical Society, 1998
Ionic fragmentation of methylmethacrylate has been observed using synchrotron radiation and laser excitation. A recently developed time-of-flight mass spectrometer was used for the ionic identification.

Implementing a multivariate curve resolution method optimized by alternating least square (MCR-ALS) to deconvolute overlapping spectral polymer signals in SEC-DAD separations [PDF]

open access: yes, 2013
Peaks eluting from a size exclusion separation are often not completely baseline-separated, due to the inherent polydispersity of the polymer and low efficiency of the separation mechanism.

CryoSift: an accessible and automated CNN‐driven tool for cryo‐EM 2D class selection

open access: yesActa Crystallographica Section F, Volume 81, Issue 12, Page 517-526, December 2025.
CryoSift is a CNN‐based tool that assesses the quality of 2D class averages. The incorporation of CryoSift into cryoSPARC workflows enables automated particle‐stack cleaning.Single‐particle cryo‐electron microscopy (cryo‐EM) has become an essential tool in structural biology.

Liquid recirculation in microfluidic channels by the interplay of capillary and centrifugal forces [PDF]

open access: yes, 2009
We demonstrate a technique to recirculate liquids in a microfluidic device, maintaining a thin fluid layer such that typical diffusion times for analytes to reach the device surface are < 1 min.
