Abstract Accurate measurement of cavity swelling in a transmission electron microscope is essential to define material performance under irradiation, and the conventionally applied spherical assumption for the calculation of cavity volumes in irradiated materials can result in errors ranging between a 25% underestimation and 72% overestimation of volume purely based on the assumption of shape.

Bulan Ramadhan merupakan bulan dimana umat Islam menjalani puasa selama sebulan, dimulai dari terbitnya matahari hingga terbenamnya. Di samping berpuasa, berkah yang ada dalam bulan Ramadhan juga berhubungan dengan berbagai aktivitas keagamaan seperti melaksanakan shalat tarawih, membaca Al-Quran, berdonasi, serta melakukan berbagai amal baik lainnya. Bulan ini juga dikenal sebagai waktu yang penuh dengan pengampunan serta rahmat dari Allah SWT.

Abstract Refractory multiprincipal element alloys (rMPEAs) are potential materials for the plasma-facing components in future fusion reactors due to their high melting point, strength and irradiation resistance. However, the concurrent optimization of ductility and high-temperature properties remains a significant challenge due to the complex interdependence between alloy chemistry, mechanical behavior, and thermodynamic stability.
