Written by AZoOpticsJan 21 2021 Robots are extensively used to paint airplanes, make cars, and sew clothing in factories. However, the assembly of microscopic components, for example, those used for biomedical applications, is yet to be automated. Lasers could offer a solution to this problem. Scientists have now used lasers to develop miniature robots using bubbles that lift, drop, and control tiny pieces into interconnected structures. The study results have been published in the ACS Applied...

Robots are widely used to build cars, paint airplanes and sew clothing in factories, but the assembly of microscopic components, such as those for biomedical applications, has not yet been automated. Lasers could be the solution. Now, researchers reporting in ACS Applied Materials & Interfaces have used lasers to create miniature robots from bubbles that lift, drop and manipulate small pieces into interconnected structures.

Abstract One big challenge for long-lived inverted perovskite solar cells (PSCs) is that commonly used metal electrodes react with perovskite layer, inducing electrode corrosion and device degradation. Motivated by the idea of metal anticorrosion, here, we propose a chemical anticorrosion strategy to fabricate stable inverted PSCs through introducing a typical organic corrosion inhibitor of benzotriazole (BTA) before Cu electrode deposition. BTA molecules chemically coordinate to the Cu electro...
