Current Opinion in Structural Biology, 1992 Abstract Bulges are important structural elements in RNA and DNA. Progress has been made in defining the sequence dependence of the structure and stability of bulges; however, the molecular interactions responsible for these sequence effects are not yet completely understood.

Cyclo‐N9−: a Novel 5/6 Fused Polynitrogen Anion for High Energy Density Materials
Advanced Science, EarlyView.This study presents a novel 5/6 fused polynitrogen anion, cyclo‐N9−, which is assembled with four cations to form energetic salts. The computational results reveal that the energy densities and detonation performances of these systems are far superior, even surpassing those of CL‐20.

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids
Advanced Science, EarlyView.This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for

Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores
Advanced Science, EarlyView.A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.

The Milky Way Bulge: Observed properties and a comparison to external galaxies
, 2015 The Milky Way bulge offers a unique opportunity to investigate in detail the role that different processes such as dynamical instabilities, hierarchical merging, and dissipational collapse may have played in the history of the Galaxy formation and ...

Advanced Science, EarlyView.In this work, low lattice thermal conductivity and high carrier mobility are revealed in single crystalline Mg3Bi2, a promising thermoelectric material. An increase of thermopower as a “hump” ≈20 K is found, where phonon drag effect contributes large portion by replacing diffusive electrons.

The Rotation of Classical Bulges in Barred Galaxies in the Presence of Gas
UniverseBarred galaxies often develop a box/peanut pseudobulge, but they can also host a nearly spherical classical bulge, which is known to gain rotation due to the bar. We aim to explore how the presence of gas impacts the rotation of classical bulges.
