High‐Performance n‐Type Organic Thermoelectrics Enabled by Control Over Microstructure, Orientation and Contact Plane in Naphthalenediimide‐Bithiazole‐Copolymer Films

open access: yesAdvanced Functional Materials, EarlyView.
Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Validation of the Scientific Program for the Dark Energy Spectroscopic Instrument

open access: yesThe Astronomical Journal
The Dark Energy Spectroscopic Instrument (DESI) was designed to conduct a survey covering 14,000 deg ^2 over 5 yr to constrain the cosmic expansion history through precise measurements of baryon acoustic oscillations (BAO).

Tracing the sound horizon scale with photometric redshift surveys [PDF]

open access: yes, 2010
We propose a new method for the extraction cosmological parameters using the baryon acoustic oscillation (BAO) scale as a standard ruler in deep galaxy surveys with photometric determination of redshifts.

Tannic Acid‐Modified Cellulose Nanofiber Reinforced Polymerizable Eutectogels for High‐Performance Stretchable Strain Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A polymerizable deep eutectic solvent is reinforced with tannic acid‐modified cellulose nanofibers to construct a hierarchical dynamic eutectogel network. Synergistic covalent and reversible interactions impart ultrahigh stretchability, high ionic conductivity, broad temperature tolerance, self‐healing, and strong adhesion, enabling robust wearable ...

Deep Spectroscopy with DESI for Photometric Redshift Training and Calibration

open access: yesThe Astronomical Journal
Deep spectroscopic samples can improve photometric redshift (photo- z ) estimates and reduce uncertainties on redshift distributions. Such improvements can increase the cosmological constraining power of large imaging-based experiments such as the Vera C.

SHELS: TESTING WEAK-LENSING MAPS WITH REDSHIFT SURVEYS [PDF]

open access: yes, 2009
Weak-lensing surveys are emerging as an important tool for the construction of “mass-selected” clusters of galaxies. We evaluate both the efficiency and completeness of a weak-lensing selection by combining a dense, complete redshift survey, the ...

n‐Type Semiconductor Hydrogels for Tunable Organic Electrochemical Transistors Operation and Evaporation‐Driven Synergistic Energy Harvesting and Thermal Management

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a tunable n‐OSC hydrogel (PBFDO‐PAAc) platform with a tunable porous network and thermoelectric properties. It demonstrates the first report of n‐OSC hydrogels for evaporation‐driven hydrovoltaic‐thermoelectric electricity generation as well as chemically dedoping‐mediated OECT working mode reconfiguration. This work expands n‐OSCs’

Probing dark energy with future redshift surveys: a comparison of emission line and broad‐band selection in the near‐infrared [PDF]

open access: yes, 2009
Future galaxy surveys will map the galaxy distribution in the redshift interval 0.5 -15.4 and a flux limit of at least log(F H α[erg s -1 ] cm -2 ]) = -16 is required for an Hα sample to become competitive in effective volume.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

open access: yesAdvanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.
