The potential to exploit single-walled carbon nanotubes (SWNTs) in advanced electronics represents a continuing, major source of interest these materials. However, scalable integration SWNTs into circuits is challenging because difficulties controlling the geometries, spatial positions, and electronic properties individual tubes. We have implemented solutions some challenges yield radio frequency (RF) SWNT analog devices, such as narrow band amplifiers operating VHF with power gains high 14...
Abstract Background A comprehensive update of the classification all available kinases was carried out. This survey presents a complete global picture this large functional class proteins and confirms soundness our initial kinase scheme. Results The new found total number sequences in protein database has increased more than three-fold (from 17,310 to 59,402), determined structures two-fold 359 702) past three years. However, framework original two-tier scheme (in families fold groups)...
Abstract Nanoporous carbons (NPCs) with engineered specific pore sizes and sufficiently high porosities (both surface area volume) are necessary for storing energy in the form of electric charges molecules. Herein, NPCs, derived from biomass pine‐cones, coffee‐grounds, graphene‐oxide metal‐organic frameworks, systematically increased width (<1.0 nm to a few nm), micropore volume (0.2–0.9 cm 3 g −1 ) (800–2800 m 2 presented. Superior CO , H 2, O uptakes 35.0 wt% (≈7.9 mmol at 273 K), 3.0...
Reduced graphene-oxide (RGO)-based electrodes in supercapacitors deliver high energy/power capacities compared to typical nanoporous carbon materials. However, extensive critical analysis of literature reveals enormous discrepancies (up 250 F g-1 ) the reported capacitance (variation 100-350 RGO materials synthesized under seemingly similar methods, inhibiting an understanding variation. Here, key factors that control performance are demonstrated by analyzing and optimizing various types...
Carbon nanotube Schottky diodes were fabricated using asymmetric metal-nanotube contacts. These devices prepared from semiconducting single-walled carbon nanotubes contacted by one Al or Ti electrode and Au electrode. Nanotubes formed a low resistance contact with the Electronic transport through barriers was determined competition between tunneling thermionic emission, which could be tuned back gate voltage.
A comparative genomic approach was used to reconstruct transcriptional regulation of NAD biosynthesis in bacteria containing orthologs Bacillus subtilis gene yrxA , a previously identified niacin-responsive repressor de novo synthesis. Members YrxA family (re-named here NiaR) are broadly conserved the Bacillus/Clostridium group and deeply branching Fusobacteria Thermotogales lineages. We analyzed upstream regions genes associated with identify candidate NiaR-binding DNA motifs assess NiaR...
A novel family of transcription factors responsible for regulation various aspects NAD synthesis in a broad range bacteria was identified by comparative genomics approach. Regulators this (here termed NrtR Nudix-related transcriptional regulators), currently annotated as ADP-ribose pyrophosphatases from the Nudix family, are composed an N-terminal Nudix-like effector domain and C-terminal DNA-binding HTH-like domain. regulons were reconstructed diverse bacterial genomes identification...

The authors consider the suitability of carbon nanotubes for use in analog rf amplifiers, where linearity device is critical. They show that limit large electrostatic gate-channel capacitance, their theory predicts an Ohmically contacted, ballistic carbon-nanotube-based field-effect transistor inherently linear. While they have not achieved this experimental work, compare to experiment small capacitance and find excellent agreement at virtually all bias conditions.
Four tetraphenyl silsesquioxane based covalent-organic frameworks (sil-COFs) have been designed under a ctn or bor net topology as high-capacity hydrogen storage materials.
Carbonized metal–organic frameworks (MOFs)-based nanoporous carbon materials (NPCs) offer attractive activities in electrochemical energy conversion and storage (EECS) applications; however, there is the need for scalable MOFs production under reduced energy/environmental impact. This study reports a green synthesis route model zeolitic imidazolate framework (ZIF-8) via recycling methanol-based mother liquors (ZIF-RMLx) room temperature stirring their carbonized (CZC-RMLx) high-performance...
A top-gated carbon nanotube (CNT) field-effect transistor (FET) was fabricated on a quartz substrate. We used novel measurement approach and demonstrated for the first time frequency-independent performance of CNT FET frequencies as high 23GHz. This observed maximum operating frequency represents significant breakthrough in realization nanotube-based electronics applications.
The enzymatic activity of Pseudomonas fluorescens α-amino-β-carboxymuconic-ε-semialdehyde decarboxylase (ACMSD) is critically dependent on a transition metal ion [Li, T., Walker, A. L., Iwaki, H., Hasegawa, Y., and Liu, (2005) J. Am. Chem. Soc. 127, 12282−12290]. Sequence analysis in this study further suggests that ACMSD belongs to the amidohydrolase superfamily, whose structurally characterized members comprise catalytically essential cofactor. To identify ACMSD's ligands assess their...

Abstract Phototheranostics integrates light‐based diagnostic techniques with therapeutic interventions, offering a non‐invasive, precise, and swift approach for both disease detection treatment. The efficacy of this hinges on the multimodal imaging potential photothermal conversion efficiency (PCE) phototheranostic agents (PTAs). Despite promise, crafting multifunctional organic small molecules brims challenges. In research, four innovative xanthene‐derived PTAs are synthesized by...

Supercapacitors formed from porous carbon and graphene‐oxide (GO) materials are usually dominated by either electric double‐layer capacitance, pseudo‐capacitance, or both. Due to these combined features, reduced GO have been shown offer superior capacitance over typical nanoporous materials; however, there is a significant variation in reported values, ranging between 25 350 F g −1 . This undermines the structure (e.g., oxygen functionality and/or surface area)‐performance relationships for...
