Princeton University is a private Ivy League research university in Princeton, New Jersey. Founded in 1746 in Elizabeth as the College of New Jersey, Princeton was the fourth chartered institution of higher education in the American colonies and thus one of the nine Colonial Colleges established before the American Revolution. The institution moved to Newark in 1747, then to the current site nine years later, where it was renamed Princeton University in 1896. The present-day College of New Jersey in nearby Ewing Township, New Jersey, is an unrelated institution. Princeton had close ties to the Presbyterian Church, but has never been affiliated with any denomination and today imposes no religious requirements on its students.Princeton provides undergraduate and graduate instruction in the humanities, social science, natural science, and engineering. It offers professional degrees through the Woodrow Wilson School of Public and International Affairs, the School of Engineering and Applied Science, the School of Architecture and the Bendheim Center for Finance. The University has tied with the Institute for Advanced Study, Princeton Theological Seminary, and the Westminster Choir College of Rider University. By endowment per student, Princeton is the wealthiest school in the United States.Princeton has been associated with 37 Nobel laureates, 17 National Medal of Science winners, two Abel Prize winners, eight Fields Medalists , nine Turing Award laureates, three National Humanities Medal recipients and 204 Rhodes Scholars.

Methods described herein enable the production of numerous molecular species through decarboxylative cross-coupling via use of photoredox and transition metal catalysts. For example, methods described herein enable the production of numerous molecular species through decarboxylative cross-coupling via use of photoredox and transition metal catalysts. A method described herein, in some embodiments, comprises providing a reaction mixture including a photoredox catalyst, a transition metal catalyst, a coupling partner and a substrate having a carboxyl group. The reaction mixture is irradiated with a radiation source resulting in cross-coupling of the substrate and coupling partner via a mechanism including decarboxylation, wherein the coupling partner is selected from the group consisting of a substituted aromatic compound and a substituted aliphatic compound.

Passive components adapted for integration with at least one active semiconductor device, in an embodiment, comprise at least one metallic structure dimensioned and arranged to absorb and/or reflect a major fraction of incident electromagnetic radiation received at one or more wavelengths of a first group of wavelengths. This prevents radiation within the first group of wavelengths from being received and/or processed by the at least one active device. In an embodiment, one or more metallic structures are dimensioned and arranged to direct an amount of incident radiation, received at one or more wavelengths of a second group of wavelengths, sufficient to enable receiving or processing of incident radiation within the second group of wavelengths by the at least one active semiconductor device. In some embodiments, the passive component comprises a passive optical filter for use in spectroscopic applications, and the active semiconductor device is a detector or sensor.

An inverse precipitation route to precipitate aqueous soluble species with copolymers as nanoparticles having a hydrophilic, polar core and a less polar shell is described. A method of the invention for encapsulating water soluble molecules using rapid, controlled precipitation is presented. Water soluble molecules - including peptides, proteins, DNA, RNA, non-biologic therapeutics, polysaccharide-based therapeutics (e.g., tobramycin) and imaging agents - precipitate into nanoparticles that are protected by a copolymer stabilizing agent. These particles may be covalently or non-covalently stabilized. The particles may be coated with an amphiphilic polymer, or processed into microparticles or larger monoliths. Post processing on the final construct may be conducted.

Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface. These states are possible due to the combination of spin-orbit interactions and time-reversal symmetry. The two-dimensional (2D) topological insulator is a quantum spin Hall insulator, which is a close cousin of the integer quantum Hall state. A three-dimensional (3D) topological insulator supports novel spin-polarized 2D Dirac fermions on its surface. In this Colloquium the theoretical foundation for topological insulators and superconductors is reviewed and recent experiments are described in which the signatures of topological insulators have been observed. Transport experiments on HgTe/CdTe quantum wells are described that demonstrate the existence of the edge states predicted for the quantum spin Hall insulator. Experiments on Bi1_xSbx, Bi2Se3, Bi2Te3, and Sb2Te3 are then discussed that establish these materials as 3D topological insulators and directly probe the topology of their surface states. Exotic states are described that can occur at the surface of a 3D topological insulator due to an induced energy gap. A magnetic gap leads to a novel quantum Hall state that gives rise to a topological magnetoelectric effect. A superconducting energy gap leads to a state that supports Majorana fermions and may provide a new venue for realizing proposals for topological quantum computation. Prospects for observing these exotic states are also discussed, as well as other potential device applications of topological insulators. © 2010 The American Physical Society.

Core-collapse theory brings together many facets of high-energy and nuclear astrophysics and the numerical arts to present theorists with one of the most important, yet frustrating, astronomical questions: "What is the mechanism of core-collapse supernova explosions?" A review of all the physics and the 50-year history involved would soon bury the reader in minutiae that could easily obscure the essential elements of the phenomenon, as we understand it today. Moreover, much remains to be discovered and explained, and a complicated review of an unresolved subject in flux could grow stale fast. Therefore, this paper describes various important facts and perspectives that may have escaped the attention of those interested in this puzzle. Furthermore, an attempt to describe the modern theory's physical underpinnings and a brief summary of the current state of play are given. In the process, a few myths that have crept into modern discourse are identified. However, there is much more to do and humility in the face of this age-old challenge is clearly the most prudent stance as its eventual resolution is sought. © 2013 American Physical Society.
