We design and synthesize two isomeric fused-ring electron acceptors, FNIC1 FNIC2, which have the same end-groups side-chains, but fused-nine-ring cores. Subtle changes in isomers influence their electronic, optical, charge-transport, morphological properties. As compared with FNIC1, FNIC2 film exhibits a red-shifted absorption peak at 794 nm (752 for FNIC1), larger affinity of 4.00 eV (3.92 smaller ionization energy 5.56 (5.61 higher mobility 1.7 × 10–3 cm2 V–1 s–1 (1.2 FNIC1). The as-cast...
Boceprevir is a hepatitis C virus (HCV) nonstructural protein (NS) 3/4A protease inhibitor that currently being evaluated in combination with peginterferon alfa-2b and ribavirin phase 3 studies. The clinical resistance profile of boceprevir not characterized detail so far. NS3 domain viral RNA was cloned from HCV genotype 1–infected patients (n = 22). A mean number 47 clones were sequenced before, at the end, after treatment 400 mg twice or three times daily for 14 days genotypic,...
Cleavage of the hepatitis C virus (HCV) polyprotein by viral NS3 protease releases functional proteins essential for replication. Recent studies Foy and coworkers strongly suggest that NS3-mediated cleavage host factors may abrogate cellular response to alpha interferon (IFN-alpha) (E. Foy, K. Li, R. Sumpter, Jr., Y.-M. Loo, C. L. Johnson, Wang, P. M. Fish, Yoneyama, T. Fujita, S. Lemon, Gale, Proc. Natl. Acad. Sci. USA 102:2986-2991, 2005, E. Ikeda, Science 300:1145-1148, 2003). Blockage...
Materials providing broadband light antireflection have applications as highly transparent window coatings, military camouflage, and coatings for efficiently coupling into solar cells out of light-emitting diodes. In this work, densely packed silicon nanotextures with feature sizes smaller than 50 nm enhance the compared that predicted by their geometry alone. A significant fraction nanotexture volume comprises a surface layer whose optical properties differ substantially from those bulk,...
Na<sup>+</sup>diffuses and re-dissolves into matrix grains, resulting in carrier concentration modulation thereby superior high temperature TE performances.
Wearable double-twisted fibrous perovskite solar cells are developed based on flexible carbon nanotube fiber electrodes, which exhibit a maximum power conversion efficiency of 3.03% and bending stability larger than 1000 cycles, maintain 89% after 96 h in ambient conditions if sealed by transparent polymer layer. The obtained superior performance can shed light future self-powering e-textiles.
With the increased interest in development of hydrogen fuel cells as a plausible alternative to internal combustion engines, recent work has focused on creating alkaline (AFC), which employ an environment. Working opposed acidic media yields number tangible benefits, including (i) ability use cheaper and plentiful precious-metal-free catalysts, due their stability, (ii) reduction amount degradation corrosion Pt-based (iii) longer operational lifetime for overall cell configuration. However,...
MoTe$_2$ is an exfoliable transition metal dichalcogenide (TMD) which crystallizes in three symmetries, the semiconducting trigonal-prismatic $2H-$phase, semimetallic $1T^{\prime}$ monoclinic phase, and orthorhombic $T_d$ structure. The $2H-$phase displays a band gap of $\sim 1$ eV making it appealing for flexible transparent optoelectronics. $T_d-$phase predicted to possess unique topological properties might lead topologically protected non-dissipative transport channels. Recently, was...
Heterogeneous electrode materials with hierarchical architectures promise to enable considerable improvement in future energy storage devices. In this study, we report on a tailored synthetic strategy used create heterogeneous tungsten sulfide/oxide core-shell nanofiber vertically and randomly aligned thorn-bush features, evaluate them as potential anode for high-performance Na-ion batteries. The WSx (2 ≤ x 3, amorphous WS3 crystalline WS2) is successfully prepared by electrospinning...

Doped motifs offer an intriguing structural pathway toward improving conductivity for battery applications. Specifically, Ca-doped, three-dimensional "flower-like" Li4–xCaxTi5O12 ("x" = 0, 0.1, 0.15, and 0.2) micrometer-scale spheres have been successfully prepared the first time using a simple reproducible hydrothermal reaction followed by short calcination process.
