A Review of Analytical and Chemometric Strategies for Forensic Classification of Homemade Explosives

open access: yesAnalytical Science Advances, Volume 6, Issue 1, June 2025.
ABSTRACT Homemade explosives (HMEs), commonly used in improvised explosive devices (IEDs), present a significant forensic challenge due to their chemical variability, accessibility and adaptability. Traditional forensic methodologies often struggle with environmental contamination, complex sample matrices and the non‐specificity of precursor residues ...

Application of Carbon Quantum Dots in Food Business: A Comprehensive Review

open access: yeseFood, Volume 6, Issue 3, June 2025.
This approach is straightforward and practical in comparison to previous approaches because it speeds up the synthesis of CQDs while maintaining a high quantum yield. By heating the poly (ethylene glycol) (PEG‐200) for 2–10 min. However, there are several downsides of this technique, such as the nonuniform particle sizes of carbon quantum dots that ...

The Compound Capacity of Polar Codes [PDF]

open access: yesarXiv, 2009
We consider the compound capacity of polar codes under successive cancellation decoding for a collection of binary-input memoryless output-symmetric channels. By deriving a sequence of upper and lower bounds, we show that in general the compound capacity under successive decoding is strictly smaller than the unrestricted compound capacity.

Sorption of Sulfonamide Antibiotics in Peat Soils With Different Properties

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 3, Page 482-494, June 2025.
Sulfonamide antibiotics contaminate peat soils where they are sorbed to functional groups in a pH‐dependent manner that can be successfully described by QSAR. ABSTRACT Background Sulfonamide antibiotics have been discovered as emerging pharmaceutical pollutants worldwide and are only poorly removed in wastewater treatment.

Capacities of classical compound quantum wiretap and classical quantum compound wiretap channels [PDF]

open access: yesarXiv, 2012
We determine the capacity of the classical compound quantum wiretapper channel with channel state information at the transmitter. Moreover we derive a lower bound on the capacity of this channel without channel state information and determine the capacity of the classical quantum compound wiretap channel with channel state information at the ...

Phylogenomic and Pangenomic Assessment of a Mediterranean Strain of Raphidiopsis raciborskii Extends Knowledge of the Global Distribution and Characteristics of a Potentially Toxigenic Cyanobacterium

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 3, June 2025.
The potentially toxigenic cyanobacterium Raphidiopsis raciborskii has spread to temperate regions and produces massive blooms. This study reports the first taxonomic and functional metagenomic assessment of a strain from the Mediterranean, thus filling a significant gap in global distribution.
