  • Solid samples can be imaged and chemically analysed using secondary ion mass spectrometry. This Primer describes the secondary ion mass spectrometry experimental setup, in which a primary ion beam sputters secondary ions that are analysed and detected by a mass spectrometer, and explores applications in materials, geological and life sciences.

  • Freeze casting involves directional solidification of solutions or slurries followed by removal of the solid solvent phase. This Primer introduces the freeze casting technique, including experimental and analysis methods, with a particular focus on using X-ray tomoscopy for real-time, 3D observations of freeze casting dynamics.

  • Single-case experimental designs are rapidly growing in popularity. This popularity needs to be accompanied by transparent and well-justified methodological and statistical decisions. Appropriate experimental design including randomization, proper data handling and adequate reporting are needed to ensure reproducibility and internal validity. The degree of generalizability can be assessed through replication.

  • Bayesian optimization is a promising approach towards a more environmentally friendly chemical synthesis, in line with the Sustainable Development Goals. It can aid chemists to explore vast chemical spaces and find green reaction conditions with few experiments, decreasing resource consumption and waste generation while reducing discovery timelines and costs.

  • New nanomaterials are being developed for efficient biomolecule delivery to plants. However, detection and quantification of plant cell entry are challenging and currently rely on subjective methods that lack proper controls. The necessary considerations of performing nanoparticle-mediated delivery in plants and how to accurately quantify delivery efficiency are discussed.
