Self-assembly of molecular and block copolymer amphiphiles represents a well-established route to micelles with a wide variety of shapes and gel-like phases. We demonstrate an analogous process, but on a longer length scale, in which amphiphilic P-H-P and H-P-H cylindrical triblock comicelles ...

After many years out of the limelight, antimicrobial resistance (AMR) in bacteria is firmly back on the international political and scientific agenda (1, 2). The potential impact of AMR on hospital-acquired bacterial infections such as Staphylococcus aureus and Acinetobacter baumannii in ...

Proteins are the workhorse of life. They assemble the structural elements of the cell, catalyze metabolism, regulate cellular functions, and even transcribe and repair DNA. Many of the proteins' functions are related to their physical shape and conformations. For example, protein-folding problems ...

Long, balanced electron and hole diffusion lengths greater than 100 nanometers in the polycrystalline organolead trihalide compound CH3NH3PbI3 are critical for highly efficient perovskite solar cells. We found that the diffusion lengths in CH3NH3PbI3 single crystals grown by a solution-growth ...

Structural alloys are often strengthened through the addition of solute atoms. However, given that solute atoms interact weakly with the elastic fields of screw dislocations, it has long been accepted that solution hardening is only marginally effective in materials with mobile screw ...

State-of-the-art photovoltaics use high-purity, large-area, wafer-scale single-crystalline semiconductors grown by sophisticated, high-temperature crystal growth processes. We demonstrate a solution-based hot-casting technique to grow continuous, pinhole-free thin films of organometallic ...
30-Jan-2015 | G. T. Dunning; D. R. Glowacki; T. J. Preston; S. J. Greaves; G. M. Greetham; I. P. Clark; M. Towrie; J. N. Harvey; A ..., Science , 2015
Solvent-solute interactions influence the mechanisms of chemical reactions in solution, but the response of the solvent is often slower than the reactive event. Here, we report that exothermic reactions of fluorine (F) atoms in d3-acetonitrile and d2-dichloromethane involve efficient energy flow ...

Later this spring, Japan is likely to restart the first two of the 48 nuclear reactors idled in the aftermath of the 2011 meltdowns at the Fukushima Daiichi Nuclear Power Station. But the resumption of nuclear power generation is refocusing attention on a lingering challenge: what to do with the ...

The solution to a decades-old space mystery may help save satellites from deadly radiation.

Hollow mixed-metal oxide nanoparticles can be made by replacing the metal cations through redox reactions in solution. [Also see Perspective by Ibáñez and Cabot]
