High-rate electrochemical energy storage through Li+ intercalation pseudocapacitance.
Pseudocapacitance is commonly associated with surface or near-surface reversible redox reactions, as observed with RuO2·xH2O in an acidic electrolyte. However, we recently demonstrated that a… Expand
Synthesis of Ultra-Incompressible Superhard Rhenium Diboride at Ambient Pressure
The quest to create superhard materials rarely strays from the use of high-pressure synthetic methods, which typically require gigapascals of applied pressure. We report that rhenium diboride (ReB2),… Expand

Capacitive energy storage is distinguished from other types of electrochemical energy storage by short charging times and the ability to deliver significantly more power than batteries. A key… Expand
Size Dependence of a First Order Solid-Solid Phase Transition: The Wurtzite to Rock Salt Transformation in CdSe Nanocrystals
Measurements of the size dependence of a solid-solid phase transition are presented. High-pressure x-ray diffraction and optical absorption are used to study the wurtzite to rock salt structural… Expand

The advantages in using nanoscale materials for electrochemical energy storage are generally attributed to short diffusion path lengths for both electronic and lithium ion transport. Here, we… Expand
The wurtzite to rock salt structural transformation in CdSe nanocrystals under high pressure
Structural transformations in CdSe nanocrystals are studied using high pressure x‐ray diffraction and high pressure optical absorption at room temperature. The nanocrystals undergo a wurtzite to rock… Expand

Tungsten tetraboride (WB4) is an interesting candidate as a less expensive member of the growing group of superhard transition metal borides. WB4 was successfully synthesized by arc melting from the… Expand
Promoter evolution in BK virus: functional elements are created at sequence junctions.
The archetypal strain of BK virus directed very little early gene expression compared with rearranged laboratory strains of the virus. One laboratory strain that was analyzed in detail contained… Expand
Reappraising the Need for Bulk Heterojunctions in Polymer−Fullerene Photovoltaics: The Role of Carrier Transport in All-Solution-Processed P3HT/PCBM Bilayer Solar Cells
The most efficient organic solar cells produced to date are bulk heterojunction (BHJ) photovoltaic devices based on blends of semiconducting polymers such as poly(3-hexylthiophene-2,5-diyl) (P3HT)… Expand
Advancements in the Search for Superhard Ultra‐Incompressible Metal Borides
Dense transition metal borides have recently been identified as superhard materials that offer the possibility of ambient pressure synthesis compared to the conventional high pressure, high… Expand
