Barbican-inspired bimetallic core–shell nanoparticles for fabricating natural leather-based radiation protective materials with enhanced X-ray shielding capability

From natural leather to intelligent wearable nanocomposite: design and application

“…As the thickness increases, the time for multiple reflections of electromagnetic waves on leather increases; then, more electromagnetic wave energy is consumed. At the same time, leather, as a promising natural material, has excellent X-ray protection capabilities due to its multilayer woven structure that complements other functional materials [65][66][67] .…”

Preventing the Galvanic Replacement Reaction toward Unconventional Bimetallic Core–Shell Nanostructures

“…Bimetallic nanocrystals are receiving increasing interest in optics [1][2][3], catalysis [4][5][6][7][8][9][10], and many other fields [11][12][13][14][15]. For example, bimetallic nanocrystals are an excellent class of catalysts for many industrial processes and energy conversion thanks to their intriguing catalytic properties arising from the electronic and geometric interactions between constituent metals [8][9][10].…”

Bi2O3/Gd2O3 Meta-Aerogel with Leaf-Inspired Nanotrap Array Enables Efficient X-Ray Absorption

“…To overcome this challenge, researchers have been pursuing the rational design of dual-phase X-ray absorbers exhibiting distinct and complementary K absorption edges, aiming to capitalize on the advantages offered by each phase absorber. − Studies have demonstrated that Bi 2 O 3 and Gd 2 O 3 exhibit complementary K absorption edges and have been utilized to develop X-ray shielding materials with high efficiency (via impregnation, coating, or blending). Nevertheless, the majority of these approaches have yielded 2D film materials, which exhibit relatively limited flight paths for X-rays and thereby offer restricted enhancements in shielding efficiency.…”
