Electrical Design of Electrostatic Deflectors for Sector-Focused Cyclotrons [PDF]

, 1963
The new sector-focused cyclotrons have more energetic and better focused beams at the extraction radius than do ordinary cyclotrons. While the first characteristic requires a more intense electric field, the second permits this field to extend over a ...

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

Small, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

Rounded Monodisperse Fluorescent Nanodiamonds

Small, EarlyView.
Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.
