A Sophisticated Terahertz Photonic Crystal Fiber Sensor Design for Highly Accurate Detection of Kerosene Mixtures

Advanced Physics Research, EarlyView.
A novel Photonic Crystal Fiber sensor with an octagonal cladding and hollow core is developed to detect kerosene adulteration. At 2.2 THz, the sensor achieves 96.80% relative sensitivity, an effective mode loss of 0.00667 cm⁻¹, and minimal confinement loss (6.78 × 10⁻8 dB m−1).

Metal‐Mediated Protein Engineering within Live Cells

Chemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
This review discusses how metal ions can mediate protein modification within live cells. With its easy handling, rapid solubility, and ease of internalization within the cells, metal ions can be an excellent stimulus for many organic reactions needed within an intracellular medium, which can modify proteins and lead to applications in chemistry ...

Identification of a L‐threonine‐utilizing hydrazine synthetase for thrazarine biosynthesis in Streptomyces coerulescens MH802‐fF5

ChemBioChem, Accepted Article.
Hydrazine synthetases (HSs), consisting of cupin and methionyl‐tRNA synthetase (MetRS)‐like domains, catalyze hydrazine formation in the biosynthesis of various nitrogen‐nitrogen (N‐N) bond‐containing secondary metabolites. The structural diversity of the N‐N bond‐containing secondary metabolites synthesized using this system is attributed to the ...

Electronic and Magnetic Properties of Ferrous Iron in a True Square‐Planar Molecular Environment

Chemistry – A European Journal, EarlyView.
Spin Hamiltonian parameters of an iron(II) phthalocyanine are obtained by pNMR, THz‐EPR, and quantum chemical calculations. Large zero field splitting and the peculiar g‐tensor pattern originate from mixing of the 3A2g ground state with two 3Eg‐excited states of almost the same energy. This forms the basis for correlations between magnetism, structure,
