Investigating Slit-Collimator-Produced Carbon Ion Minibeams with High-Resolution CMOS Sensors

open access: yesInstruments, 2023
Particle minibeam therapy has demonstrated the potential for better healthy tissue sparing due to spatial fractionation of the delivered dose. Especially for heavy ions, the spatial fractionation could enhance the already favorable differential ...

Bright, green fluorescent carbon dots for sensitive and selective detection of ferrous ions

open access: yesTalanta Open, 2023
Iron is critical to living organisms; excess or lack of iron could lead to a series of diseases. In this work, fluorescent carbon dots were developed as an efficient probe for sensitive and selective detection of ferrous ions (Fe2+).

Determination of carbonate ion by ion chromatography.

open access: yesBUNSEKI KAGAKU, 1996
Determination of carbonate ion by ion chromatography was investigated. The separation was performed on a TSKgel IC-Anion-PWXL (4.6 mm i.d.×35 mm) with boric acid-ethylenediamine buffer. The influence of the eluent pH on the capacity factors of carbonate and some inorganic anions was studied.

The Potential of Commercial Biomass-Based Activated Carbon to Remove Heavy Metals in Wastewater – A Review

open access: yesJurnal Ilmu Lingkungan, 2023
Commercial activated carbon is a type of adsorbent commonly used in adsorption processes. However, the use of commercial carbon in wastewater treatment is still limited, due to the scarce availability of precursors and their high cost.

Monte Carlo-based Investigation of Absorbed-dose Energy Dependence of Thermoluminescent Dosimeters in Therapeutic Proton and Carbon Ion Beams

open access: yesJournal of Medical Physics
Background: The present study is aimed at calculating relative absorbed-dose energy response correction (R) of commonly used thermoluminescent dosimeters (TLDs) such as LiF, Li2B4O7, and Al2O3 as a function of depth in water for protons (50–250 MeV/n ...
