Biochar is proposed as a promising solution for sustainable development, but proper risk management and careful evaluation are essential when considering its use. It is crucial to acknowledge the limitations of biochar and recognize that it is not a magic bullet for green technologies.
Higher education and research institutions are critical to the well-being and success of societies, meaning their financial support is strongly in the public interest. At the same time, value-for-money principles demand that such investment delivers. Unfortunately, these principles are currently violated by one of the biggest sources of public funding inefficiency: sexism.
3D printing can be used to automate the manufacturing of building elements for large-scale structures such as skyscrapers, aircraft, rockets and space bases without human intervention. However, challenges in materials, processes, printers and software control must first be overcome for large-scale 3D printing to be adopted for widespread applications.
An article in Nature Communications presents a general method to create intermixed 2D/3D heterostructures to improve the stability of all-perovskite tandem solar cells.
An article in Nano Letters presents a strategy for the growth of single-crystal bismuthene by sandwiching it between hexagonal boron nitride and copper.
An article in Angewandte Chemie International Edition resurfaces metal halide perovskite nanocrystals with a reactive, liquid ligand to produce efficient and stable red perovskite light-emitting diodes.
An article in Nature Materials shows that a ‘quantum dot molecule’ — two fused and electronically coupled quantum dots — can easily switch between two distinct emission colours when induced by an electric field.
An article in the Journal of the American Chemical Society decorates type-I CdS-ZnS core–shell quantum dots with metallic domains to activate them as hydrogen evolution photocatalysts.
An article in Science uses photogenerated nitrene radicals to non-specifically bond together colloidal inorganic nanocrystals as they are 3D printed into robust functional structures.
An article in Nature Communications uses an artificial-intelligence-guided robot to accelerate the discovery and fabrication of chiroptically active films.
This Comment discusses metal–organic frameworks and their progress towards translation in a health-care setting. We explore their prospects in clinical applications, why translation seems slow, and what opportunities and obstacles await as they move towards the clinic.
