Researchers have found a way to make the Casimir effect attract or repulse depending on the size of the gap between two objects. The Casimir effect is the phenomenon in which two tiny surfaces in close proximity experience a force that pulls them closer together. The researchers suggest their technique could be used in nanomechanical devices or in computers.
Scientists have created the world's first portable, inexpensive, optical nanoscopy tool that integrates a glass optical fiber with a silver nanowire condenser. The device is a high-efficiency round-trip light tunnel that squeezes visible light to the very tip of the condenser to interact with molecules locally and send back information about these molecules.

Scientists have developed a highly efficient catalyst for extracting electrical energy from ethanol, an easy-to-store liquid fuel that can be generated from renewable resources. The chemical structure of the catalyst consists of a gold nanoparticle with platinum and iridium atoms on its surface.

Materials science researchers have discovered a new process for producing oxide perovskite crystals in flexible, free-standing layers. A two-dimensional rendition of this substance is intriguing to scientists and engineers because some two-dimensional materials have been shown to display high-temperature superconductivity and are prized as potential building blocks for quantum computing devices.

Scientists have been able to reverse multiple sclerosis symptoms in mice with a nanotechnology treatment derived from bone marrow stem cells. In past experiments, intravenously injected stem cells often got trapped in filter organs before reaching their target. For this study, the researchers avoided that problem by extracting nano-sized particles called exosomes from the stem cells and injecting them into mice with multiple sclerosis.

Researchers have found that a form of nanoscale corrosion is responsible for unpredictably decreasing the working life of steel pipes. The researchers were able to pin the root of the problem on a triple junction formed by a grain of cementite—a compound of carbon and iron—and two grains of ferrite, a type of iron.
