Researchers have developed a 'coloring-by-shrinking' method to print arbitrary 3D microscopic objects exhibiting structural colors. The design consisted of woodpile photonic crystals with varying lattice constants as the 3D building blocks. These structures remain colorless until they are heat treated, causing them to shrink and manifest color, a result of their lattice constants shrinking down below the wavelength of visible light. The team printed a colorful microscopic Eiffel Tower with structural colors, demonstrating feature sizes smaller than 100 nm.

Researchers have reported the high-performance SnS thermoelectric crystals combining the desirable features of low-cost, earth-abundant materials and environmental friendliness. For the first time, they discovered the interplay of triple electronic bands leading to the high performance of thermoelectric SnS crystals, which is promoted by Se alloying. Furthermore, Se alloying plays a second important role in lowering the thermal transport.
