This paper reviews key properties, applications, and examples of ceramic−metal composites (cermets) and metal matrix composites (MMCs) with emphasis on their applicability as waste forms for immobilizing nuclear waste. While the literature is mature for vitrified and cementitious radioactive waste forms, cermet materials have not received adequate attention as potential candidates for immobilizing nuclear waste. To promulgate this effort, this review connects cermet and MMC design, such as hardened tools, with the chemistry of radioactive waste streams. This paper includes a discussion on certification and qualification standards for cermet waste forms, literature gaps, and "how-to" sections on cermet processing techniques. Key parameters discussed include thermal conductivity, chemical durability, and waste loading, as well as examples for metal-containing waste forms. As cermet waste forms gain momentum within the community, this review paper aims to ensure the end-of-life nuclear fuel cycle is addressed from a materials and waste disposition perspective.

“…Hence, if there are not enough transgender candidates belonging to SC and ST categories then the proportionate number of seats meant for transgender candidates get transferred to the OC category. 34 So we recommend that reservation for transgender and intersex persons should be compartmentalized to ensure that the intersectional discrimination experienced by various groups is addressed through the reservation quota policy. Adivasi communities tend to be overlooked in the mainstream narratives around caste and gender identity.…”

CLPR’s ” Making Rights Real” policy brief recognises that reservations are critical in addressing the livelihood concerns of the transgender and intersex community and proposes the manner of implementation of such reservations. In suggesting a framework for providing reservations, the policy brief stays true to the principle of self-identification of gender identity, traces the legal and constitutional framework on reservations in India, and considers legislative, executive, and judicial efforts at providing reservations of transgender and intersex persons so far.

“…Powder metallurgy is a near-net-shape manufacturing technique that consists of the consolidation of powders into a predefined shape and that provides the metallurgy integrity and mechanical resistance of the parts manufactured [11][12][13] . Therefore, this manufacturing method is an alternative to conventional processes such as casting, forging, or extrusion [8,13] .…”

In this study, samples of 420 stainless steel were obtained by hot pressing from powder at temperatures from 1,100 to 1,200 ºC. The aim was to explore the influence of the processing temperature on their grain size, microstructure, densification and mechanical properties. The results showed that it is possible to produce dense samples at these sintering temperatures. The sintering temperature influenced the density, grain size, structural phases, and hardness of the samples. Martensite and austenite were present in the samples sintered at 1,100, 1,150, and 1,180 ºC. Precipitation of Cr23C6 was observed after sintering at 1,200 ºC. This sample was the one with the highest density (99.7 % densification) and hardness (771.9 HV).
