Published: July 2013

AbstractCe3+‐, Tb3+‐, and Mn2+‐activated Ca9MgNa(PO4)7 (CMNP) phosphors have been prepared by a Pechini‐type sol–gel method. X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), and photoluminescence (PL) and cathodoluminescence (CL) spectroscopy were used to characterize the samples. The energy transfer from Ce3+ to Tb3+ in CMNP phosphors has been demonstrated to be a resonant type by a dipole–quadrupole mechanism, and the Ce3+ to Tb3+ critical distances (RC) calculated by the concentration‐quenching method and the spectral‐overlap method are 12.21 and 12.11 Å, respectively. A color‐tunable emission in CMNP phosphors can be realized by Ce3+→Tb3+ or Ce3+→Mn2+ energy transfer. White cathodoluminescence has been realized in a single‐phase Ca9MgNa(PO4)7 host by codoping with Ce3+, Tb3+, and Mn2+ for the first time with International Commission on Illumination (CIE) chromaticity coordinates (0.319, 0.327). Furthermore, the cathodoluminescence (CL) properties of CMNP:Ce3+/Tb3+/Mn2+ phosphors, including the dependence of the CL intensity on accelerating voltage and filament current, the decay behavior of CL intensity under electron bombardment, and the stability of the CIE chromaticity coordinates, have been investigated in detail. Owing to their good CL properties and good CIE chromaticity coordinates, the as‐prepared phosphors have potential application in field emission display (FED) devices.

AbstractRuthenium(II) complexes [(η6‐cymene)RuCl(apypm)]BPh4 with bidentate 2‐amino‐4‐(2‐pyridinyl)pyrimidine (apypm) ligands catalyze the transfer hydrogenation of acetophenone. Their activities are strongly dependent on the substituent pattern of the pyrimidine ring. Complexes bearing a primary amino group in the 2‐position of the pyrimidine ring do not perform the catalysis in terms of a “bifunctional mechanism”, although they possess protic hydrogen atoms at the amino moiety in close proximity to the metal site. Systems containing tertiary dialkylated amino substituents at the apypm ligand are the first examples of air‐stable and phosphane‐free transfer‐hydrogenation catalysts that show high activities even in the absence of a base. A new mechanism for the catalyst activation in the absence of an external base is proposed on the basis of ESI‐MS investigations and ab initio calculations combined with isotope labelling: C–H bond cleavage at the pyrimidine ring is the crucial step for the generation of the catalytically active species.

In this work, a first level investigation was carried out to study the extra virgin olive oils (EVOOs) obtained from secular olive trees of Apulia region. Microextracted olive oil samples from selected and genetically characterized olive trees were studied by 1H NMR‐based metabolomic approach and multivariate analysis, according to cultivar and geographic origin, within the Apulia region. The 1H NMR spectra of oils were analyzed by several pattern recognition methods, using both unsupervised (principal component analysis) and supervised (partial least squares discriminant analysis, orthogonal partial least squares discriminant analysis (OPLS‐DA)) statistical techniques. EVOOs obtained from secular olive trees could be easily differentiated by OPLS‐DA not only depending on the used cultivars but also according to their geographical origin within the different districts of the Apulia region, such to justify a larger biodiversity maintenance of Apulia secular germplasm. Therefore, differences in chemical composition and NMR profiles of EVOOs may be explained either by cultivars or geographic areas.Practical applications: About 10% of the genetic olive tree patrimony within the Apulia region consists of the secular olive trees. A recently introduced regional law (No 14 of June 4th, 2007) allows to exploit oil produced from secular olive trees by labeling it with the special mention: “extra virgin oil from the Apulia secular olive trees”. Characterization of extra virgin olive oils obtained from secular trees may be an optimal solution to increase the value for this product and make it available on the market. On the other hand this economic issue is very important to preserve the unique landscape offered by the ancient olive groves of the Apulia region in south east Italy.

AbstractA series of new D–D–π–A‐type organic dyes – CCTnA (n = 1–3), CCT3N and CCT2PA, bearing the 3‐(3′,6′‐di‐tert‐butylcarbazol‐N′‐yl)‐N‐dodecylcarbazol‐6‐yl system as an electron donor moiety (D–D) – were synthesized by convenient methods and successfully utilized as dye sensitizers for dye‐sensitized solar cells (DSSCs). The central π‐conjugated bridges were made of oligothiophene and oligothiophene‐phenylene units, whereas the acceptor groups were either cyanoacrylic acid or cyanoacrylamide. Detailed investigation into the relationship between the structures, spectral and electrochemical properties, and performances of the DSSCs is described. The DSSC devices performed remarkably well, with typical overall conversion efficiencies of 3.60–5.69 %, and optimal incident photon‐to‐current conversion efficiencies (IPCEs) exceeding 80 %. The devices containing oligothiophene bridging groups performed better than those with oligothiophene‐phenylene bridging groups. Of solar cells based on these dyes, the CCT3A‐based one gave a maximum IPCE value of 84 %, a short‐circuit photocurrent density (Jsc) of 11.31 mA cm–2, an open‐circuit voltage (Voc) of 0.71 V and a fill factor (FF) of 0.71, corresponding to an overall conversion efficiency (η) of 5.69 % (>96 % of that of the reference N719‐based cell, η = 5.92 %). This work suggests that the organic dyes based on donor moieties or donor molecular architectures of this type are promising candidates for improvement of the performances of DSSCs.

AbstractRecent studies have demonstrated resting‐state abnormalities in midline regions in vegetative state/unresponsive wakefulness syndrome and minimally conscious state patients. However, the functional implications of these resting‐state abnormalities remain unclear. Recent findings in healthy subjects have revealed a close overlap between the neural substrate of self‐referential processing and the resting‐state activity in cortical midline regions. As such, we investigated task‐related neural activity during active self‐referential processing and various measures of resting‐state activity in 11 patients with disorders of consciousness (DOC) and 12 healthy control subjects. Overall, the results revealed that DOC patients exhibited task‐specific signal changes in anterior and posterior midline regions, including the perigenual anterior cingulate cortex (PACC) and posterior cingulate cortex (PCC). However, the degree of signal change was significantly lower in DOC patients compared with that in healthy subjects. Moreover, reduced signal differentiation in the PACC predicted the degree of consciousness in DOC patients. Importantly, the same midline regions (PACC and PCC) in DOC patients also exhibited severe abnormalities in the measures of resting‐state activity, that is functional connectivity and the amplitude of low‐frequency fluctuations. Taken together, our results provide the first evidence of neural abnormalities in both the self‐referential processing and the resting state in midline regions in DOC patients. This novel finding has important implications for clinical utility and general understanding of the relationship between the self, the resting state, and consciousness.

Published: July 2013

AbstractBackgroundLow back pain (LBP) is a prevalent problem and tends to be socio‐economically patterned. Relatively little is known about life‐course socio‐economic circumstances as determinants of different types ofLBP. Our aim was to examine whether childhood and adult socio‐economic position and social mobility are associated with radiating and non‐specificLBPand sciatica.MethodData were derived from theYoungFinnsStudy (n = 2231). Childhood socio‐economic position was based on parental education, occupational class and family income at baseline in 1980. Data on own education andLBPoutcomes were collected at the end of follow‐up in 2007. Social mobility was based on parental and own education. Covariates were composed of age, parental body mass index and smoking.ResultsBoth childhood and own socio‐economic position remained associated with radiatingLBPand sciatica after adjustments. However, the associations varied by socio‐economic indicator and gender. Stable lower socio‐economic position and downward mobility were associated with radiatingLBP.ConclusionChildhood socio‐economic circumstances affect the risk of radiatingLBPand sciatica in adulthood. To prevent low back disorders, early socio‐economic circumstances need to be considered alongside own socio‐economic position.

9.1: Frontal Projection‐type Three‐dimensional Display with Enhanced Brightness Uniformity

Published: July 2013

AbstractA method to uniformize the brightness of elemental image for the frontal projection‐type three‐dimensional (3D) display is proposed. A frontal projection three‐dimensional display which is possible to realize glasses‐free 3D display by combining a polarizing screen with a front projector has been proposed recently. This method uses a quarter‐wave retarding film (QWRF) and a polarizer with slits, and makes the audience see different directional views. This structure can change the polarization state orthogonally, so the image from projector is partially blocked when the image is reflected and meets the films. However, in this method, the quality of the reconstructed 3D image could be degraded since the light intensity at the barrier‐free regions of parallax barrier polarizer is brighter than that at the parallax barrier polarizer. We proposed two methods to relieve this difference, a parallax barrier rearrangement method and gray level compensation of illumination. By adopting two methods, we anticipate that the quality of reconstructed 3D image can be enhanced because of brightness uniformity in directional‐view images in the frontal projection‐type 3D display method.

Published: July 2013

AbstractIn this study, we reported the capability of a new composition oxide TFTs, fabricated using sputtering process and successfully developed including sputtering target with single‐phase. In order to compare single‐phase target with multiphase target, as‐deposited films by same sputtering condition for sputtering process were prepared and the chemical characterization of target, as‐deposited film, and annealed films, respectively by using EPMA and ICP analyses were evaluated. Single‐phase target had a uniform and homogeneous metal composition distribution without segregation. In addition, after annealing process, the films were maintained the chemical composition. We, therefore, selected single target and evaluated the electrical performances. The saturation mobility (μsat) was measured to be 22.4 cm2V−1s−1. In addition, threshold voltage (Vth) was 0.75 V and subthreshold swing (SS) was 0.44 V/decade, respectively. This study could encourage in developing a novel composition oxide TFTs with high mobility.

Published: July 2013

AbstractThe effect of polymer system on polymer‐stabilized blue phase liquid crystals (PSBPLCs) is investigated. The experimental results indicate that the electro‐optic properties of PSBPLC are affected by the interface energy between the liquid crystal molecules and polymer system. As the anchoring energy of polymer system decreases, the driving voltage will decrease, but hysteresis and residual birefringence will increase. In addition, if the anchoring energy is less than a threshold value, the BPLC cannot be stabilized well by polymer network.

Published: July 2013

AbstractThis paper proposes a 3.4Gbps/lane intra‐panel interface with 11.1% of the protocol overhead for the raw data to be transmitted. The proposed intra‐panel interface uses a point‐to‐point interface architecture with embedded clock. To reduce the EMI radiation, the scrambling scheme was adopted. The protocol of the proposed intra‐panel interface provides a PLL based clock and data recovery (CDR) scheme for the receiver. Timing controller (TCON) and source driver (SD) are implemented using 45nm/1.1V and 0.18um/1.8V CMOS processes, respectively. The proposed interface is verified on a 55‐inch Full‐HD TFT‐LCD panel with 8bit RGB and 120‐Hz frame rates. The maximum data rate per lane was measured as up to 3.4Gbps/lane.

35.4: Programmable Pulse Width LTPS TFT Shift Register for High Resolution and High Frame Rate Active Matrix Flat Panel Displays
Authors: Song Eunji , Nam Hyoungsik 
Published: July 2013

AbstractThis paper proposes a programmable pulse width LTPS TFT shift register where an output pulse width is programmed only by adjusting a start pulse width without any additional clock signals and reconfiguration. Since an overlap interval of the output pulses is easily controlled in the shift register which operates with precharging scheme, the proposed shift register can be applied to high resolution and high frame rate display without the problem of insufficient line time. The performance of this circuit is verified by SMART SPICE at low‐temperature poly silicon (LTPS) thin film transistor (TFT) process. The pulse width is changed by the step size of two line time with only two input clock signals which leads to small area for circuit implementation and simulated power consumption is similar to that of the conventional shift register.
