Article Abstract
The microstructural evolutions of precipitates formed in a Cu75-Fe5-Ni20 alloy on isothermal annealing at 873 K and 1073 K have been investigated by means of transmission electron microscopy (TEM). Nano-scale magnetic particles were formed randomly in the Cu-rich matrix after receiving a short annealing due to phase decomposition in the alloy. With increasing the isothermal annealing time, however, the striking features that two or more nano-scale particles with a cubic shape and a rod shape were aligned linearly along (100) directions were observed on isothermal annealing at 873 K and 1073 K, respectively. To investigate electro-magnetic properties of precipitates in a Cu-Fe-Ni alloy, the superconducting quantum interference device (SQUID) magnetometer and physical property measurement system (PPMS) were also complemented. The present study revealed significant influences that the magnetic properties of the specimens were closely related to the microstructures in the Cu-Fe-Ni alloy, which microstructures significantly depend on the isothermal annealing temperature.

CRISPR-Cas genome editing is a powerful tool in various fields, but current cloning methods can be time-consuming due to the frequent use of intermediate entry vectors and multiple steps involving restriction enzymes and ligases. These multiple steps can create a bottleneck in CRISPR-Cas experiments. In response to this challenge, we propose a highly efficient streamlined approach, which enables simultaneous linearization of the acceptor plasmid and protospacer cloning in a single isothermal reaction.

Unlabelled: Mosaic disease, caused by whitefly-transmitted begomoviruses, significantly threatens bitter gourd cultivation in India. This study identified and characterized the complete genome of coccinia mosaic Virudhunagar virus (CoMViV) from symptomatic bitter gourd samples collected in Oddanchatram block of Dindigul district, Tamil Nadu, using rolling circle amplification and sequencing. A loop-mediated isothermal amplification (LAMP) protocol was optimized by targeting regions of the CoMViV AV1 and AV2 genes.

In this study, the crystallization behavior of amorphous terfenadine (TFD) was investigated with a focus on nucleation temperature. The cold crystallization behavior of amorphous TFD annealed at various temperatures and the resultant crystal form were evaluated by using differential scanning calorimetry and powder X-ray diffraction. Samples annealed at -20 °C provided the lowest cold crystallization temperature and the highest proportion of form II, indicating that nucleation for form II was enhanced at a temperature much lower than the glass transition temperature (58 °C).

An anion exchange-assisted technique was used for the synthesis of platinum-decorated SnO supports, providing nanocatalysts with enhanced activity for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). In this study, a series of SnO supports, namely SnA (synthesized almost at room temperature), SnB (hydrothermally treated at 180 °C), and SnC (annealed at 600 °C), are systematically investigated, all loaded with 1 mol% Pt from HPtCl under identical mild conditions. The chloride ions from the SnCl precursors were efficiently removed via a strong-base anion exchange reaction, resulting in highly dispersed, crystalline ~5 nm cassiterite SnO particles.

Toxic dyes present in wastewater pose a severe threat to aquatic ecosystems, emphasizing the urgent need for eco-friendly and efficient remediation strategies. In this study, we report a novel rapid synthesis protocol for graphitic carbon nitride (g-CN) nanosheets via thermal polymerization of thiourea, followed by annealing in ambient air at 550 °C for two hours. The resulting g-CN nanosheets were employed as adsorbents for the removal of methylene blue (MB) and rhodamine B (RhB) from aqueous solution.
