Square wave anodic stripping voltammetry determination of eco-toxic metals in samples of biological and environmental importance
Authors: Anastasiadou Zefi , Jannakoudakis Panagiotis , Girousi Stella 
Published: September 2010

Abstract
Square wave anodic stripping voltammetry was used in simultaneous determinations of eco-toxic metals (Pb, Cd, Cu and Zn) on bismuth film electrodes. The electrodes were prepared in situ on a glassy-carbon electrode (GCE) from 0.1 M acetate buffer (pH 4.5) containing 200 μg L−1 of bismuth (III), as well ex situ on electrochemically oxidized graphitized polyacrylonitrile carbon fibres from 200 mg L−1 Bi(NO3)3 in 1% HNO3 (aqueous) solution. Preparation of a Bi-modified carbon fibre electrode (CFE) was by cation exchange of Bi+3 ions for H+ of the acidic surface groups of the electro-oxidized carbon fibres, followed by electrochemical reduction to Bi0. For the Bi-GCE the linear range was 20–280 μg L−1 for zinc, 10–100 μg L−1 for lead, 10–80 μg L−1 for copper, and 5–50 μg L−1 for cadmium. For the Bi-CFE it was 20–160 μg L−1 for zinc, 10–100 μg L−1 for lead, 10–100 μg L−1 for copper, and 2–120 μg L−1 for cadmium. For both kinds of bismuth modified carbon electrodes, low limits of detection and satisfactory precision were achieved. The method was successfully applied to certified reference materials of biological (bovine liver) and environmental (mussel tissue) importance.

AbstractThe long wavelength (8–12 μm) IR FPA 288×4 based on a hybrid assembly of n+-p diode photosensitive arrays (PA) of HgCdTe (MCT) MBE-grown structures and time delay integration (TDI) readout integrated circuits (ROIC) with bidirectional scanning have been developed, fabricated, and investigated. The p-type MCT structures were obtained by thermal annealing of as-grown n-type material in inert atmosphere. The MCT photosensitive layer with the composition 0.20–0.23 of mole fraction of CdTe was surrounded by the wide gap layers to decrease the recombination rate and surface leakage current. The diode arrays were fabricated by planar implantation of boron ions into p-MCT. The typical dark currents were about 4–7 nA at the reverse bias voltage of 150 mV. The differential resistance R was up to R0 = 1.6×107 Ω zero bias voltage, which corresponded to R0A ∼70 Ω ·cm2 and to the maximal value Rmax = 2.1 × 108 Ω. The bidirectional TDI deselecting ROIC was developed and fabricated by 1.0-μm CMOS technology with two metallic and two polysilicon layers.The IR FPAs were free of defect channels and have the average values of responsivity Sλ = 2.27×108 V/W, the detectivity Dλ * = 2.13 × 1011 cm × Hz1/2 × Wt1, and the noise equivalent temperature difference NETD = 9 mK.

Published: September 2010

AbstractThe acceptor doping of mercury cadmium telluride (HgCdTe) layers grown by MOCVD are investigated. (111)HgCdTe layers were grown on (100)GaAs substrates at 350°C using horizontal reactor and interdiffused multilayer process (IMP). TDMAAs and AsH3 were alternatively used as effective p-type doping precursors. Incorporation and activation rates of arsenic have been studied. Over a wide range of Hg1−xCdxTe compositions (0.17 < x < 0.4), arsenic doping concentration in the range from 5×1015 cm−3 to 5×1017 cm−3 was obtained without postgrowth annealing. The electrical and chemical properties of epitaxial layers are specified by measurements of SIMS profiles, Hall effect and minority carrier lifetimes. It is confirmed that the Auger-7 mechanism has decisive influence on carrier lifetime in p-type HgCdTe epilayers.

AbstractThe electrical properties of the interface between Hg1−xCdxTe (x = 0.22 and x = 0.32–0.36) and CdTe prepared in situ molecular beam epitaxy were estimated at 77 K. The methods of determination of main parameters of interface semiconductor/insulator and insulator from capacitance-voltage characteristics of MIS-structures based on graded-band Hg1−xCdxTe have been developed. The fixed charge states density, fast surface states density, and density of mobile charge are obtained from capacitance-voltage measurements. For improvement in stable and electrical strength of insulator coating for several samples over CdTe additional protective layers SiO2-Si3N4 are formed for x = 0.22 and ZnTe for x = 0.32–0.36.
Nature of gallium deep centres in lead telluride based semiconductors
Authors: Petrenko T.L. , Plyatsko S.V. 
Published: September 2010

AbstractDoped with Ga lead telluride was taken as a model object to explain the nature of group-III deep levels in IV-VI semiconductors and to elucidate the vapour phase doping mechanism. For this goal, interaction of various gallium-containing molecules with defect-free crystal as well as with native defects in PbTe was considered. Formation energies for different point defects created in PbTe as a result of interaction the Ga2Te molecules, Ga2 dimers and single Ga atoms with a host crystal were calculated using density functional theory. Particularly GaPb and Gai together with formation of accompanied self interstitials Pbi in various charge states were examined. In addition we propose the new type of defects - the impurity complex (2Ga)Pb which looks like <111>-oriented gallium dumbbell. Calculations suggest the double donor behaviour and DX-like properties of this defect together with extremely low formation energy values. Namely, (2Ga)Pb centres are preferably formed under Ga2Te doping while (Ga2)Pb+Pbi ones are formed under Ga2 or Ga doping. In all cases, formation energies are negative and resulting defect concentration is determined by reaction kinetics only. Mechanisms of the lead vacancy compensation with the vapour phase doping are considered as well.
High frequency response of near-room temperature LWIR HgCdTe heterostructure photodiodes

Published: September 2010

AbstractThe high frequency response of near-room temperature long wavelength infrared (LWIR) HgCdTe heterostructure photodiodes is investigated using a Fourier space method. The MOCVD HgCdTe multilayer heterostructures were grown on GaAs substrates. The response time of devices as a function of bias has been measured experimentally by using 10-μm quantum cascade laser and fast oscilloscope with suitable transimpedance amplifier. Results of theoretical predictions are compared with experimental data. It is shown that the response time at weak reverse bias condition is mainly limited by the drift time of carriers moving into π-n+ junction. Using the reverse bias higher than 50 mV, the transit time across the absorber region limits the response time. The response time of small-area devices decreases in the region of week reverse bias achieving value below 1 ns.

Understanding attitudes toward people with Down syndrome
Authors: Pace Jill E. , Shin Mikyong , Rasmussen Sonja A. 
Published: September 2010

AbstractUnderstanding attitudes of the public toward people with Down syndrome is important because negative attitudes might create barriers to social integration, which can affect their success and quality of life. We used data from two 2008 U.S. surveys (HealthStyles© survey of adults 18 years or older and YouthStyles© survey of youth ages 9–18) that asked about attitudes toward people with Down syndrome, including attitudes toward educational and occupational inclusion and toward willingness to interact with people with Down syndrome. Results showed that many adults continue to hold negative attitudes toward people with Down syndrome: A quarter of respondents agreed that students with Down syndrome should go to special schools, nearly 30% agreed that including students with Down syndrome in typical educational settings is distracting, and 18% agreed that persons with Down syndrome in the workplace increase the chance for accidents. Negative attitudes were also held by many youth: 30% agreed that students with Down syndrome should go to separate schools, 27% were not willing to work with a student with Down syndrome on a class project, and nearly 40% indicated they would not be willing to spend time with a student with Down syndrome outside of school. Among both adult and youth, female sex and respondents with previous relationships with people with Down syndrome were consistently associated with more positive attitudes. These results may be helpful in the development of educational materials about Down syndrome and in guiding policies on educational and occupational inclusion. Published 2010 Wiley‐Liss, Inc.
Imprinted genes and human disease
Authors: Weksberg Rosanna 
Published: September 2010

AbstractThis issue of Seminars of Medical Genetics features a series of articles on human disorders caused by the dysregulation of imprinted genes. At the outset, there is a review of the general mechanisms by which genomic imprinting is normally regulated followed by an exploration of the clinical and molecular aspects of human imprinting disorders. As we enter an era of bioinformatics and genome‐wide analyses with increasing access to high density microarrays and next generation sequencing, it is becoming apparent that the concept of a single mutation or epimutation leading to a disease is outdated. The role of the clinician will become increasingly important, in concert with these molecular advances, in terms of evaluating phenotypic variation to further our understanding of imprinting disorders. Such investigations will benefit children and families as we become better able to define recurrence risk, predict phenotype, and tailor medical management. © 2010 Wiley‐Liss, Inc.
Uniparental disomy and human disease: An overview
Authors: Yamazawa Kazuki , Ogata Tsutomu , Ferguson‐Smith Anne C. 
Published: September 2010

AbstractUniparental disomy (UPD) refers to the situation in which both homologues of a chromosomal region/segment have originated from only one parent. This can involve the entire chromosome or only a small segment. As a consequence of UPD, or uniparental duplication/deficiency of part of a chromosome, there are two types of developmental risk: aberrant dosage of genes regulated by genomic imprinting and homozygosity of a recessive mutation. UPD models generated by reciprocal and Robertsonian translocation heterozygote intercrosses have been a powerful tool to investigate genomic imprinting in mice, whereas novel UPD patients such as those with cystic fibrosis and Prader–Willi syndrome, triggered the clarification of recessive diseases and genomic imprinting disorders in human. Newly developed genomic technologies as well as conventional microsatellite marker methods have been contributing to the functional and mechanistic investigation of UPD, leading to not only the acquisition of clinically valuable information, but also the further clarification of diverse genetic processes and disease pathogenesis. © 2010 Wiley‐Liss, Inc.
Transient neonatal diabetes mellitus type 1
Authors: Mackay Deborah J.G. , Temple I. Karen 
Published: September 2010

AbstractTransient neonatal diabetes mellitus type 1 (TNDM1) is a rare but remarkable form of diabetes which presents in infancy, resolves in the first months of life, but then frequently recurs in later life. It is caused by overexpression of the imprinted genes PLAGL1 and HYMAI on human chromosome 6q24. The expression of these genes is normally restricted to the paternal allele as a result of maternal DNA methylation. TNDM1 is not associated with mutation of PLAGL1 or HYMAI, but rather with their overexpression via uniparental disomy, chromosome duplication, or relaxation of imprinting. Study of patients with TNDM1 has provided valuable insights into the causes of imprinting disorders. Over half of patients with maternal hypomethylation at the TNDM1 locus have additional hypomethylation of other maternally methylated imprinted genes throughout the genome, and the majority of these patients have mutations in the transcription factor ZFP57. TNDM1 with maternal hypomethylation has also been observed in patients conceived by assisted reproduction, and in discordant monozygotic twins. The variable clinical features of TNDM1 may be associated with variation in the nature of the underlying epigenetic and genetic mutations, and future study of this disorder is likely to yield further insights not only into the biological mechanisms of imprinting, but also into the contribution of epigenetics to diabetes. © 2010 Wiley‐Liss, Inc.
