ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Diffuse radio emission in the complex merging galaxy cluster Abell 2069
Galaxy clusters with signs for a recent merger show in many cases extended diffuse radio features. This emission originates from relativistic electrons which suffer synchrotron losses due to the intra-cluster magnetic field.

PolSpec: Polarisation‐Based Detection for Versatile, Cost‐Effective Rapid Hyperspectral Imaging
“PolSpec” is a fast, flexible, data efficient and cost‐effective technique for hyperspectral imaging utilising polarisation‐based spectral modulation. Using data‐efficient representation of spectral information on vector plots, it facilitates rapid visualisation and segmentation of spectral contrast to classify sample features. As a proof of concept, a

In this talk, I will review the current status of the Sardinia Radio Telescope and the near-future technical developments. In particular, I will discuss the new generation receivers and focus on the spectroscopic capabilities of the telescope and on the impact that the SRT could have in the field of star formation .

Dynamic Multi‐Focus 3D Laser Nanoprinting Based on Two‐Step Absorption and Computational Holography
Low single‐focus laser powers in two‐step‐absorption 3D laser nanoprinting make parallelization efforts a viable route to increase print speeds while still relying on compact continuous‐wave lasers. Herein, an established two‐step‐absorption photoresist system with computational holography based on a digital micromirror device is combined in order to ...

Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Search for possible exomoons with FAST telescope
Our knowledge of the Solar System, encourages us to beleive that we might expect exomoons to be present around some of the known exoplanets. With present hardware and existing optical astronomy methods we shall not be able to find exomoons at least 10 ...

Ergonomic Evaluation of a Walk‐Behind AI‐Based Cotton Fertilizer Applicator
ABSTRACT The mechanization of agricultural operations greatly influences both the efficiency of farming operations and the health and safety of farm workers. Human exposure to working environments represents a significant hazard associated with machines and the environment.
