Albomycins are promising drug candidatesfor the treatment of bacterial infections. Here, the authors describe the totalsyntheses of albomycins δ1, δ2, and ε, and evaluate their antimicrobial activity, identifying albomycin δ2 as a strong agent against S. pneumoniae and S. aureus infections.

1. Orthogonal programming of heterogeneous micro-mechano-environments and geometries in three-dimensional bio-stereolithography

Hang Yin, Yonghui Ding, Yao Zhai, Wei Tan& Xiaobo Yin

https://www.nature.com/articles/s41467-018-06685-1

Tuning the mechanical properties of extracellular matrix is of great interest in tissue engineering but spatial control over stiffness in hydrogels has been demonstrated in two dimensionsonly. Here the authors developed a layer-by-layer printing technique which uses oxygen inhibition to control the heterogeneous stiffness in 3D printed structures.

2. Synthesis and assembly of colloidalcuboids with tunable shape biaxiality

Yang Yang, Guangdong Chen, SrinivasThanneeru, Jie He, Kun Liu & Zhihong Nie

https://www.nature.com/articles/s41467-018-06975-8

Monodisperse biaxial colloidal particles are used as model systems to understand the phase behavior of biaxial molecules but high-quality biaxial colloids are limited. Here the authors describe gram-scale synthesis of uniform biaxial colloidal cuboids and their assembly into mesophasic structures.

3. Enhanced diffusion by binding to the crosslinks of a polymer gel

Carl P. Goodrich, Michael P. Brenner &Katharina Ribbeck

https://www.nature.com/articles/s41467-018-06851-5

Gels filtering particles by interactions are a goal of nanotechnology; this is difficult when particles are larger than the mesh of the gel. Here, the authors present an equilibrium mechanism where binding dynamics of crosslinks are affected by interacting particles so that particles experience enhanced diffusion.

4. Superplasticity in an organic crystal

Satoshi Takamizawa, Yuichi Takasaki,Toshiyuki Sasaki & Noriaki Ozaki

https://www.nature.com/articles/s41467-018-06431-7

Superplasticity enables processing on hard-to-work solids but superelastic deformation, especially in asingle-crystal-to-single-crystal manner, was not demonstrated for organic crystals so far. Here the authors demonstrate asingle-crystal-to-single-crystal superplasticity in a crystal of N,N-dimethyl-4-nitroaniline.

5. Solvatochromic covalent organic frameworks

Laura Ascherl, Emrys W. Evans, Matthias Hennemann, Daniele Di Nuzzo, Alexander G. Hufnagel, Michael Beetz, Richard H. Friend, Timothy Clark, Thomas Bein & Florian Auras

https://www.nature.com/articles/s41467-018-06161-w

Covalent organic frameworks (COFs) find increasing application as sensor material, but fast switching solvatochromism was not realized. Here the authors demonstrate that combination of electron-rich and -deficient building blocks leads to COFs which fast and reversibly change of their electronic structure depending on the surrounding atmosphere.

6. Role of hydrogen bonding in hysteresis observed in sorption-induced swelling of soft nanoporous polymers

Mingyang Chen, Benoit Coasne, Robert Guyer, Dominique Derome & Jan Carmeliet

https://www.nature.com/articles/s41467-018-05897-9

Water uptake of natural polymers is accompanied by swelling and changes in the internal structure of the polymeric system but the exact mechanism of water-uptake and swelling remained unknown. Here the authors use atom-scale simulations to identify a molecular mechanism which is responsible for hysteresis in sorption-induced swelling in naturalpolymers.
