  • The Fourier transform is a mathematical tool for analysing signals that vary in space or time via a transform into the frequency domain. This Primer explores how the Fourier transform is used in analytical science, particularly for spectroscopic data, with an overview of theoretical and experimental considerations.

  • Tip-enhanced Raman scattering (TERS) can be used to access the molecular composition and structure of surfaces with extreme lateral and depth resolution, down to the nanometre scale and beyond. In this Primer, Höppener et al. discuss the underlying physical principles driving the signal enhancement and lateral resolution of TERS.

  • Element-specific electronic properties can be probed using resonant inelastic X-ray scattering (RIXS). A combination of X-ray absorption and emission, RIXS can investigate collective excitations in energy and momentum space. This Primer explores both valence and core RIXS, including background theory, experimental set-up, data analysis and example applications.

  • 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.

  • To ensure a sustainable future and combat food scarcity, we must boost agricultural productivity, improve climate resilience and optimize resource usage. There is untapped potential for dense wireless sensor networks in agriculture that can increase yields and support resilient production when linked to smart decision and control systems.

  • 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.
