Highly oriented TiO2 nanotube (NT) arrays were fabricated by anodizing Ti foils. The morphology of the NT arrays was characterized by scanning electron microscope. By adjusting the anodization time, the lengths and diameters of TiO2 NT arrays changed from 6.7 to 19.5 μm, and 90 to 110 nm, respectively. As confirmed by X-ray diffraction and Raman spectra, the as-anodized TiO2 NTs were amorphous but transformed into anatase phase after annealing at 450°C for 3 h. Reflectance spectrum of TiO 2 NT arrays showed that NT layer of longer length lowered the reflectance in the visible spectrum because of light trapping effects of NTs, thus enhancing light harvesting of NTs. Dye-sensitized solar cells were fabricated using TiO2 NT arrays with different tube-lengths. Analysis of photocurrent density-voltage (J-V) characteristics showed that higher photoconversion efficiencies were achieved with longer NT lengths. © (2011) Trans Tech Publications, Switzerland.

Never forget that China has a “managed economy.” The national government may have embraced elements of capitalism a generation ago, but the country’s leaders are well aware of the problems that can result if capitalism is allowed to run wild. “Boom or bust” syndrome is something the government thinks is bad for the economy in general and especially bad for the burgeoning electric car industry. To date, more than 200 Chinese startups have announced plans to build an electric car. 100 years ago, every blacksmith and bicycle mechanic in the world was busy building an automobile in the barn at night. Then they started companies to manufacture their creations. Worldwide, thousands if not tens of thousands of nascent car companies have failed over the last century or more. China looks at the money investors lost backing all those companies that never were. From its managed economy perspective, it thinks funneling more investment into companies that are economically viable is better for the nation than throwing good money after bad and letting market forces determine the winners and losers. Today in China, every refrigerator manufacturer, moped maker, and backyard tinkerer is jumping into the electric vehicle game. A lot of that frenzy of enthusiasm is fueled by generous government incentives that make “new energy vehicles” affordable for the masses. Those incentives can amount to as much as 60% of the sticker price of a new energy car, which has sparked a huge demand from the public. Right now in China, more than 4000 new models of electric cars are under development. Many of those small companies have no experience building automobiles. Their cars are shoddily made and service after the sale is non-existent. The government of China says it will now pick the winners itself. Soon, entrepreneurs will need a license from the government to become an automobile manufacturer. (Existing companies like SAIC and BYD will not need to apply for licenses.) According to reports, no more than 10 licenses will be issued — a very small number for such a large country. “There are too many entrants in the sector, and some of them are just speculators,” said Yin Chengliang, a professor at Shanghai Jiao Tong University’s Institute of Automotive Engineering. “The government has to raise the threshold. It’s bad to see irrational investments in projects with low technology levels.” 335,000 new energy vehicles were sold in China last year. By 2025, the government wants that number to rise to 3,000,000 vehicles a year. It will be boom times for whichever companies survive the permitting process. China’s Ministry of Industry and Information Technology published a draft policy document for public comment this month. It listed 17 technologies that companies that intend to sell electric cars must have in order to ensure “healthy” development of the industry. The factors include a control system for the performance and stability of any new energy vehicle, an information system that tracks the sources and conditions of key parts, and a process for recycling or reusing batteries. Citing unnamed sources, Economic Daily, an official newspaper run by the State Council, says 90% of the companies currently developing EV platforms won’t be able to meet the standards in two years. A lot of money has been invested in those companies already. “There’s definitely a bubble,” said Yale Zhang, a managing director at researcher Autoforesight Shanghai Co. “If you don’t own the core technology and can’t build up the brand, it’s ‘game over’ very quickly once you burn through the cash.” Drive an electric car?

Seed development dedicates to reserve synthesis and accumulation and uncovering its genetic and biochemical mechanisms has been a major research focus. Although proteomic and transcriptomic analyses revealed dynamic changes of genes and enzymes involved, the information regarding concomitant metabolic changes is missing. Here we investigated the dynamic metabolic changes along the rice grain development of two japonica and two indica cultivars using non-targeted metabolomics approach, in which we successfully identified 214 metabolites. Statistical analyses revealed both cultivar and developmental stage dependent metabolic changes in rice grains. Generally, the stage specific metabolic kinetics corresponded well to the physiological status of the developing grains, and metabolic changes in developing rice grain are similar to those of dicot Arabidopsis and tomato at reserve accumulation stage but are different from those of dicots at seed desiccation stage. The remarkable difference in metabolite abundances between japonica and indica rice grain was observed at the reserve accumulation stage. Metabolite-metabolite correlation analysis uncovered potential new pathways for several metabolites. Taken together, this study uncovered both conserved and diverse development associated metabolic kinetics of rice grains, which facilitates further study to explore fundamental questions regarding the evolution of seed metabolic capabilities as well as their potential applications in crop improvement.

BMS-690514, a potent inhibitor of human epidermal growth factor receptor (HER) 1 (EGFR), 2, and 4, and vascular endothelial growth factor receptors (VEGFR) 1-3, is currently under investigation as an oral agent for the treatment of solid tumors. In vitro and in vivo studies were conducted to characterize the pharmacokinetics and metabolism. Through integration of in vitro and in vivo pharmacokinetic data and antitumor efficacy in nude mice, human pharmacokinetics and efficacious doses were projected for BMS-690514. The oral bioavailability of BMS-690514 was 78% in mice, ∼100% in rats, 8% in monkeys, and 29% in dogs. The low oral bioavailability in monkeys could be attributed to high systemic clearance in that species, which was also consistent with predicted clearance using in vitro data from monkey liver microsomes. Permeability of BMS-690514 in Caco-2 cells was in the intermediate range with a moderate potential to be a P-gp substrate. Experiments using recombinant human CYP enzymes and human liver microsomes suggested that CYP2D6 and CYP3A4 are likely to play a key role in the metabolic clearance of BMS-690514; in addition, direct glucuronidation of BMS-690514 was also observed in human hepatocytes. BMS-690514 was able to cross the blood-brain barrier with a brain-to-plasma ratio of ∼1. The preclinical ADME properties of BMS-690514 suggest good oral bioavailability in humans and metabolism by multiple pathways including oxidation and glucuronidation. Based on the efficacious AUC in nude mice and predicted human pharmacokinetics, the human efficacious QD dose is predicted to be in the range of 100-200 mg. © 2010 Wiley-Liss, Inc. and the American Pharmacists Association.
