| 1 | Adsorption of Mn^(2+) from aqueous solution using Fe and Mn oxide-coated sand显示文摘The adsorption of Mn2+ onto immobilized Mn-oxide and Fe-oxide adsorbent such as manganese oxide-coated sand 1 (MOCS1), manganese oxide-coated sand2 (MOCS2), iron oxide-coated sand2 (IOCS2), and manganese and iron oxide-coated sand (MIOCS)was investigated. The effects of pH (5.5 to 8.0) and temperature (25 to45°C) on the equilibrium capacitywere examined. Equilibrium studies showed that there is a good fitwith both Freundlich and Langmuir isotherm,which indicates surface heterogeneity and monolayer adsorption of the adsorbents. Kineticdata showed high correlationwith the pseudo second-order model,which signifies a chemisorption-controlled mechanism. The activation energies, activation parameters (ΔG*,ΔH*,ΔS*), and thermodynamic parameters (ΔG0 , ΔH0 , ΔS0 ) confirmed that adsorptionwith MIOCSwas endothermic and more spontaneous at higher temperaturewhile an opposite trendwas observed for the other adsorbents. Thermodynamic studies showed that adsorption involved formation of activated complex,where MOCS1 and MIOCS follow a physical-chemical mechanism,while MOCS2 and IOCS2 follows purely chemical mechanism. | Chi-Chuan Kan Mannie C Aganon Cybelle Morales Futalan Maria Lourdes P Dalida | 2013 | Journal of Environmental Sciences2013，25，7： | 11 |
| 2 | Silicon carbide resonant tuning fork for microsensing applications in high-temperature and high G-shock environments显示文摘We present the fabrication and testing of a silicon carbide(SiC)balanced mass double-ended tuning fork that survives harsh environments without compromising the device strain sensitivity and resolution bandwidth.The device features a material stack that survives corrosive environments and enables high-temperature operation.To perform high-temperature testing,a specialized setup was constructed that allows the tuning fork to be characterized using traditional silicon electronics.The tuning fork has been operated at 600 ℃ in the presence of dry steam for short durations.This tuning fork has also been tested to 64 000 G using a hard-launch,soft-catch shock implemented with a light gas gun.However,the device still has a strain sensitivity of 66 Hz/με and strain resolution of 0.045 με in a 10 kHz bandwidth.As such,this balanced-mass double-ended tuning fork can be used to create a variety of different sensors including strain gauges,accelerometers,gyroscopes,and pressure transducers.Given the adaptable fabrication process flow,this device could be useful to micro-electro-mechanical systems(MEMS) designers creating sensors for a variety of different applications. | David R Myers Kan Bun Cheng Babak Jamshidi Robert G Azevedo Debbie G Senesky Li Chen Mehran Mehregany Muthu B J Wijesundara Albert P Pisano | 2012 | Engineering Sciences2012，10，5： | 6 |
| 3 | Anaerobic bacteria and intrahepatic stones: detections of Clostridium sp. and Bacteroides fragilis显示文摘To detect anaerobic bacteria Clostridium sp . and Bacteroides fragilis in intrahepatic stones by molecular genetic method Methods DNA was extracted from 59 stone samples and subjected to polymerase chain reaction (PCR) amplification targeting the 16S rRNA gene of Clostridium sp . and the glutamine synthetase gene of Bacteroides fragilis Single-strand conformational polymorphism (SSCP) analysis was performed to identify the Clostridium sp Results 16S rRNA gene sequences for Clostridium sp. were identified in 49 stones (83%, 49/59) The two most common groups were detected in 19 (41%) and 17 (37%) of the 46 samples using SSPC analysis, and 25/59 (42%) stones were tested positive for Bacteroides fragilis Conclusions Anaerobes such as Clostridium sp and Bacteroides fragilis present in intrahepatic stones and may play a role in stone formation PCR is a useful technique to detect fastidious pathogens, which are difficult to culture SSCP of PCR products is a rapid method in differentiating bacterial | LIU Yanlei Kan Lam Yajarayma J Tang Paul H Gumerlock Dong Ki Lee Myung Hwa Kim Sum P Lee Joseph SilvaJr Joseph W Leung | 2000 | Chinese Medical Journal2000，，9： | 2 |
