Rice University Researchers Develop Light-Driven, Single-Molecule Nanosubmarines

Nanoscale submarines, made of only 224 atoms and driven by ultraviolet light, have been developed. It is hoped that this technology can be further developed to allow the transport of molecular cargoes or the delivery of drugs to diseased organs.

Hybrid Silicon Heterojunction-Perovskite Solar Cell Delivers Record Efficiency

Hybrid Silicon Heterojunction-Perovskite Solar Cell Delivers Record Efficiency

Teams from the Helmholtz-Zentrum Berlin and École Polytechnique Fédérale de Lausanne, Switzerland, have been the first to successfully combine a silicon heterojunction solar cell with a perovskite solar cell monolithically into a tandem device.

Nano Power Grids Observed in Methane Degrading Microorganisms

Nano Power Grids Observed in Methane Degrading Microorganisms

Electrical energy from the socket - this convenient type of power supply is apparently used by some microorganisms. Cells can meet their energy needs in the form of electricity through nano-wire connections.

Addition of Cobalt to Nitrogen-Doped Graphene Offers Low-Cost Catalyst for Hydrogen Production

Addition of Cobalt to Nitrogen-Doped Graphene Offers Low-Cost Catalyst for Hydrogen Production

A novel solid-state catalyst that can be used to electrolyze water, with a similar efficiency to established (and expensive) platinum catalysts, has been developed. The catalyst is graphene-based with active cobalt atoms distributed across its surface. It is hoped this research will lead to cheaper water electrolysis; which is essential for the production of hydrogen to be used in fuel cells.

Quantity, Dimensions of Carbon Black Nanoparticles Crucial for Lithium-Ion Battery Function

A Stanford undergraduate has contributed to a discovery that confounds the conventional wisdom in lithium-ion battery design, pointing the way toward storage devices with more power, greater capacity, and faster charge and discharge capabilities.

Light-Activated Molecular Motors Rotate Unidirectionally at High Speed

By Jake Wilkinson A novel class of molecular motors that rotate in the same direction at high speeds upon exposure to sunlight have been developed. This novel behaviour holds promise in new nano-engineering applicatio...

Researchers Propose Standards to Compare and Select Triboelectric Nanogenerators

Researchers Propose Standards to Compare and Select Triboelectric Nanogenerators

The standards aim to quantify the performance of triboelectric nanogenerators (TENGs). Over 60 variations of TENGs are currently being developed and the standards will allow researchers to compare and select the most appropriate device for specific applications.

Researchers Synthesize DNA-Templated Gold Nanocluster for Efficient Biofuel Cell Design

Researchers Synthesize DNA-Templated Gold Nanocluster for Efficient Biofuel Cell Design

With fossil-fuel sources dwindling, better biofuel cell design is a strong candidate in the energy field. In research published in the Journal of the American Chemical Society, Los Alamos researchers and external collaborators synthesized and characterized a new DNA-templated gold nanocluster (AuNC) that could resolve a critical methodological barrier for efficient biofuel cell design.
