Bay-linked perylene bisimides as promising non-fullerene acceptors for organic solar cells
Chemical Communications, 50(8), 1024–1026.
TL;DR:
A series of bay-linked perylene bisimides as non-fullerene acceptors for organic solar cells are designed and the best power conversion efficiency up to 3.63% is demonstrated by fine-tuning optoelectronic properties resulting from different degrees of twisting and flexibility by bay-linkages.

Collision Time Measurements in a Sonoluminescing Microplasma with a Large Plasma Parameter
Physical Review Letters, 113(2), 024301.
TL;DR:
The plasma which forms inside of a micron-sized sonoluminescing bubble in water for under a nanosecond has been probed with 3 ns long laser pulses and indicates that the plasma number density is about 2×10(21) cm(-3) and that transport properties are dominated by strong screening and correlation effects.

Dynamic competition between spin-density wave order and superconductivity in underdoped Ba1−xKxFe2As2
Nat Comms, 5.
Contributors: M. Yi *, Y. Zhang*, Z. Liu*, X. Ding *, J. Chu *, A. Kemper *, N. Plonka*, B. Moritz *
TL;DR:
Spectroscopic evidence is provided for the dynamic competition between superconductivity and both SDW and electronic nematic orders in these materials by observing a coexistence of both the SDW gap and superconducting gap in the same electronic structure.

Manipulation of Gap Nodes by Uniaxial Strain in Iron-Based Superconductors
Phys. Rev. Lett., 113(21).
Contributors: J. Kang *, A. Kemper * & R. Fernandes *
TL;DR:
This work shows that not only Tc can be enhanced, but pairs of accidental gap nodes can be annihilated and created in the Fermi surface by an increasing external strain, providing a promising framework to externally control the superconducting properties of iron-based materials.

Somites Without a Clock
Science, 343(6172), 791–795.
Contributors: A. Dias*, I. Almeida*, J. Belmonte *, J. Glazier * & C. Stern *
MeSH headings : Animals; Bone Morphogenetic Proteins / antagonists & inhibitors; CLOCK Proteins / genetics; Carrier Proteins / pharmacology; Cell Communication; Circadian Clocks / drug effects; Circadian Clocks / genetics; Circadian Clocks / physiology; Gene Expression Regulation, Developmental; Homeodomain Proteins / genetics; Homeodomain Proteins / metabolism; Metabolic Networks and Pathways; Quail; Receptors, Notch / metabolism; Somites / cytology; Somites / drug effects; Somites / growth & development
TL;DR:
It is shown that it is possible to generate somites of normal size, shape, and identity without either a clock or a wavefront and the findings suggest that somite size and shape are regulated by local cell-cell interactions.
