Separating water isotopologues using diffusion-regulatory porous materials
The authors demonstrate efficient separation of water isotopologues at room temperature using two porous coordination polymers that amplify their diffusion-rate difference.

| Open AccessMaterials synthesis at terapascal static pressures
Pressures of up to 900 gigapascals (9 million atmospheres) are achieved in a laser-heated double-stage diamond cell, enabling the synthesis of Re7N3, and materials characterization is performed in situ using single-crystal X-ray diffraction.

Directed assembly of layered perovskite heterostructures as single crystals
Using organic molecules as directing groups, a wide range of perovskite heterostructures are shown to self-assemble in solution to yield single crystals.

Anthropogenic biases in chemical reaction data hinder exploratory inorganic synthesis
Human scientists make unrepresentative chemical reagent and reaction condition choices, and machine-learning algorithms trained on human-selected experiments are less capable of successfully predicting reaction outcomes than those trained on randomly generated experiments.

Chemical control of structure and guest uptake by a conformationally mobile porous material
A new metal–organic framework has several conformational degrees of freedom that can be modified by the external chemical environment to change the structure and trigger the uptake of a guest molecule.

High-temperature crystallization of nanocrystals into three-dimensional superlattices
A bottom-up process to achieve rapid growth of micrometre-sized three-dimensional nanocrystal superlattices during colloidal synthesis at high temperatures is revealed by in situ small-angle X-ray scattering; the process is applicable to several colloidal materials.

Machine-learning-assisted materials discovery using failed experiments
Failed chemical reactions are rarely reported, even though they could still provide information about the bounds on the reaction conditions needed for product formation; here data from such reactions are used to train a machine-learning algorithm, which is subsequently able to predict reaction outcomes with greater accuracy than human intuition.
