[Report] Exploiting the colloidal nanocrystal library to construct electronic devices

08-Apr-2016 | Ji-Hyuk Choi; Han Wang; Soong Ju Oh; Taejong Paik; Pil Sung; Jinwoo Sung; Xingchen Ye; Tianshuo Zhao; Benjamin T. Di ..., Science , 2016

Synthetic methods produce libraries of colloidal nanocrystals with tunable physical properties by tailoring the nanocrystal size, shape, and composition. Here, we exploit colloidal nanocrystal diversity and design the materials, interfaces, and processes to construct all-nanocrystal electronic ...


[Perspective] Feeding on plastic

11-Mar-2016 | Uwe T. Bornscheuer, Science , 2016

An estimated 311 million tons of plastics are produced annually worldwide; 90% of these are derived from petrol. A considerable portion of these plastics is used for packaging (such as drinking bottles), but only ~14% is collected for recycling (1). Most plastics degrade extremely slowly, thus ...


[Perspective] Copper catalysis in a blue light

12-Feb-2016 | Michael F. Greaney, Science , 2016

A plethora of biologically active molecules contain chiral carbon centers bearing four different functional groups. However, as more groups are added to the carbon during chemical synthesis, the more likely they are to inhibit or even block subsequent reactions on the way to full substitution. To ...


[Report] Direct observation of triplet energy transfer from semiconductor nanocrystals

22-Jan-2016 | Cédric Mongin; Sofia Garakyaraghi; Natalia Razgoniaeva; Mikhail Zamkov; Felix N. Castellano, Science , 2016

Triplet excitons are pervasive in both organic and inorganic semiconductors but generally remain confined to the material in which they originate. We demonstrated by transient absorption spectroscopy that cadmium selenide semiconductor nanoparticles, selectively excited by green light, engage in ...


[Perspective] What is an adult stem cell?

11-Dec-2015 | Hans Clevers, Science , 2015

The paradigm of the hematopoietic stem cell (HSC) has become deeply engrained in our minds, ever since bone marrow transplantation technology narrowed in on this almost magical multipotent entity that gives rise to all blood cells. The HSC's ability to “self-renew” as well as to proceed down ...


[In Depth] NSF's novel solution to a workload crunch

04-Dec-2015 | Jeffrey Mervis, Science , 2015

The National Science Foundation (NSF) frequently cites its low overhead costs when asking Congress for more money. But there's a downside to that efficiency—the risk of overloading the program officers who manage research grants. The workload problem became acute in 2004, after the number of ...


[Report] Cotranslational protein folding on the ribosome monitored in real time

27-Nov-2015 | Wolf Holtkamp; Goran Kokic; Marcus Jäger; Joerg Mittelstaet; Anton A. Komar; Marina V. Rodnina, Science , 2015

Protein domains can fold into stable tertiary structures while they are synthesized on the ribosome. We used a high-performance, reconstituted in vitro translation system to investigate the folding of a small five-helix protein domain—the N-terminal domain of Escherichia coli N5-glutamine ...


[Report] Near-unity photoluminescence quantum yield in MoS2

27-Nov-2015 | Matin Amani; Der-Hsien Lien; Daisuke Kiriya; Jun Xiao; Angelica Azcatl; Jiyoung Noh; Surabhi R. Madhvapathy; Rafik A ..., Science , 2015

Two-dimensional (2D) transition metal dichalcogenides have emerged as a promising material system for optoelectronic applications, but their primary figure of merit, the room-temperature photoluminescence quantum yield (QY), is extremely low. The prototypical 2D material molybdenum disulfide ...


[Report] Open-ocean fish reveal an omnidirectional solution to camouflage in polarized environments

20-Nov-2015 | Parrish C. Brady; Alexander A. Gilerson; George W. Kattawar; James M. Sullivan; Michael S. Twardowski; Heidi M. Dier ..., Science , 2015

Despite appearing featureless to our eyes, the open ocean is a highly variable environment for polarization-sensitive viewers. Dynamic visual backgrounds coupled with predator encounters from all possible directions make this habitat one of the most challenging for camouflage. We tested ...


[Perspective] Love at second sight for CO2 and H2 in organic synthesis

06-Nov-2015 | Jürgen Klankermayer; Walter Leitner, Science , 2015

Many romantic comedies are based on a couple with opposite personalities who fall in love, lose track of each other, and reunite against all odds, most often with the help of a mediator. This cinematic scenario recaps the recent progress in bringing together two molecular actors, carbon dioxide ...
