Single-walled carbon nanotube (SWNT) thin film electrodes have been printed on flexible substrates and cloth fabrics by using SWNT inks an off-the-shelf inkjet printer, with features of controlled pattern geometry (0.4–6 cm2), location, controllable thickness (20–200 nm), tunable electrical conductivity. The as-printed films were then sandwiched together a piece printable polymer electrolyte to form wearable supercapacitors, which displayed good capacitive behavior even after 1,000...

In the past, electrochemical instability of III–V semiconductors has severely limited their applicability in photocatlaysis. As a result, vast majority research on photocatalysis been done TiO2, which is chemically robust over wide range pH. However, TiO2 band gap (3.2 eV) and can only absorb ∼4% solar spectrum, thus, it will never provide efficient energy conversion/storage its own. Here, we report photocatalytic CO2 reduction with water to produce methanol using TiO2-passivated GaP...

All organic tested rapidly wicked to fill its void structure. local regions which are aggregated...

It is well known that the growth of osteoblast cultured on titanium with nanotube layers can be significantly increased compared to unanodized surfaces. In current study, corrosion behavior was studied in naturally aerated Hank's solution using open circuit potentials (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization tests. The results indicated TiO2 showed a better resistance simulated biofluid than smooth-Ti. OCP, rate (Icorr), passive density (Ipass)...

Here, we report photocatalytic CO2 reduction with water to produce methanol using TiO2-passivated InP nanopillar photocathodes under 532 nm wavelength illumination. In addition providing a stable surface, the TiO2-passivation layer provides substantial enhancement in photoconversion efficiency through introduction of O vacancies associated nonstoichiometric growth TiO2 by atomic deposition. Plane wave-density functional theory (PW-DFT) calculations confirm role oxygen which serve as...

Astrocyte-mediated neuroinflammation plays a critical role in ischemic stroke-induced secondary cerebral injury. Previous studies have suggested that the dopamine D2 receptor (DRD2) acts as key target regulating neuroinflammatory response. However, underlying molecular mechanisms are still unknown, and effective DRD2 agonists lacking. In present study, we examined anti-inflammatory neuroprotective effects of sinomenine (Sino), monomeric compound with potential immunoregulatory properties...
