Hybrid Cell Composed of Triboelectric Nanogenerator
Triboelectric Nanogenerators, 2016Co-Authors: Zhong Lin Wang, Jun Chen, Long Lin, Simiao NiuAbstract:There are multiple different forms of energies in our ambient environment, including mechanical energy, thermal energy, solar energy and electrochemical energy. Therefore, a Hybrid Cell with properly designed configurations is highly desired for harvesting these energies simultaneously to meet the power needs of mobile electronics. Here, different types of Hybrid Cells composed of a TENG and other energy harvesters are introduced, including AC–AC and AC–DC Hybrid Cells. In the AC–AC Hybrid Cells, TENG-EMG Hybrid generator is most intensively studied to harvest mechanical energy with high efficiency, and TENG is also Hybridized with piezoelectric and pyroelectric nanogenerators to generate power from mechanical energy and thermal energy simultaneously. In the AC–DC Hybrid Cell, TENG can be Hybridized with solar Cell, thermoelectric Cell and electrochemical Cell for simultaneously harvesting multi-types of energies whenever and wherever they are available.

silicon based Hybrid Cell for harvesting solar energy and raindrop electrostatic energy
Nano Energy, 2014Co-Authors: Zhong Lin Wang, Li Zheng, Gang Cheng, Wenzhuo WuAbstract:Abstract Silicon-based solar Cell is by far the most established solar Cell technology. The surface of a Si solar Cell is usually covered by a layer of transparent material to protect the device from environmental damages/corrosions. Here, we replaced this protection layer by a transparent triboelectric nanogeneartor (TENG), for simultaneously or individually harvesting solar and raindrop energy when either or both of them are available in our living environment. The TENG is made of a specially processed polytetrafluoroethylene (PTFE) film, an indium tin oxide (ITO) and a polyethylene terephthalate (PET) layer. Under solar light irradiation (12 W/m 2 ) in a rainy day, the fabricated high-efficiency solar Cell provides an open-circuit ( V oc ) of 0.43 V and short-circuit current density ( J sc ) of 4.2 A/m 2 . And the TENG designed for collection of raindrop energy gives an AC V oc of 30 V and J sc of 4.2 mA/m 2 when impacted by water drops at a dripping rate of 0.116 ml/s. In rainy days, the performance of solar Cell decreased greatly, while TENG can be a good compensation as for green energy harvesting. From these results, we can see that the Hybrid Cell formed by a solar Cell and a water-drop TENG have great potential for simultaneously/individually harvesting both solar energy and raindrop electrostatic energy under different weather conditions, especially in raining season.

Flexible Hybrid Cell for simultaneously harvesting thermal and mechanical energies
Nano Energy, 2013Co-Authors: Sangmin Lee, Long Lin, Sung-hwan Bae, Seunghyun Ahn, Chan Park, Sang-woo Kim, Seung-nam Cha, Young-jun Park, Zhong Lin WangAbstract:A flexible Hybrid Cell (HC) to simultaneously harvest thermal and mechanical energies is demonstrated. The output voltage and current of the HC can be well integrated under simultaneous working condition without sacrificing each output. We also demonstrate the possibility of scavenging both thermal and mechanical energies from skin temperature and body motion. This strategy can provide a highly promising platform as Hybrid Cells that simultaneously harvest multi-types of energy so that the energy resources can be effectively and complementarily utilized for power sensor network and micro/nano-systems. & 2013 Elsevier Ltd.

Optical Fiber-Based Core–Shell Coaxially Structured Hybrid Cells for Self-Powered Nanosystems
Advanced Materials, 2012Co-Authors: Caofeng Pan, Wenxi Guo, Lin Dong, Guang Zhu, Zhong Lin WangAbstract:An optical fiber-based 3D Hybrid Cell consisting of a coaxially structured dye-sensitized solar Cell (DSSC) and a nanogenerator (NG) for simultaneously or independently harvesting solar and mechanical energy is demonstrated. The current output of the Hybrid Cell is dominated by the DSSC, and the voltage output is dominated by the NG; these can be utilized complementarily for different applications. The output of the Hybrid Cell is about 7.65 μA current and 3.3 V voltage, which is strong enough to power nanodevices and even commercial electronic components.

Rearrangements between irradiated chromosomes in three-species radiation Hybrid Cell lines revealed by two-color in situ Hybridization
Human Genetics, 1993Co-Authors: C. Philippe, V. C. Nguyen, R. Slim, L. Holvoet-vermaut, M. C. Hors-cayla, A. BernheimAbstract:A human-hamster Hybrid Cell line containing only the human X chromosome (GM06318B) was exposed to 6,000–7,000 rad of X-rays and fused with a mouse Cell line (CL1D,TK^-). Three radiation Hybrids, LXKC40, LXKC50, and LXKC56, were selected among 39 independent clones containing human material. Two-color in situ Hybridization with total genomic DNA probes (cotl human DNA and hamster total genomic DNA) was used to analyse the irradiated chromosome rearrangements. With this three-species model system (human-hamster-mouse) and the chromosome painting process it was possible to determine the origin of each chromosomal fragment in metaphase and interphase. The results obtained indicate preferential rearrangement between irradiated human and hamster chromosomes. Whole, apparently intact hamster chromosomes were observed in all the mitoses. We suggest that these chromosomes could be neoformated from random fragments after irradiation. Hamster and human “minichromosomes” were also detected. While the integration of human material into the mouse genome was exceptional, the integration of hamster material into mouse chromosomes was more frequent. During interphase the irradiated chromosome domains were often at the periphery of the nucleus. Irradiated material protruded at the periphery of the nuclei. Micronuclei containing hamster material were detected in the vicinity of these protrusions.

a comparative radiation Hybrid map of bovine chromosome 18 and homologous chromosomes in human and mice
Proceedings of the National Academy of Sciences of the United States of America, 2002Co-Authors: Tom Goldammer, Srinivas R Kata, R M Brunner, Ute Dorroch, Hanka Sanftleben, M Schwerin, J E WomackAbstract:A comprehensive radiation Hybrid (RH) map and a high resolution comparative map of Bos taurus (BTA) chromosome 18 were constructed, composed of 103 markers and 76 markers, respectively, by using a cattle-hamster somatic Hybrid Cell panel and a 5,000 rad whole-genome radiation Hybrid (WGRH) panel. These maps include 65 new assignments (56 genes, 3 expressed-sequence tags, 6 microsatellites) and integrate 38 markers from the first generation WGRH5,000 map of BTA18. Fifty-nine assignments of coding sequences were supported by somatic Hybrid Cell mapping to markers on BTA18. The total length of the comprehensive map was 1666 cR5,000. Break-point positions within the chromosome were refined and a new telomeric RH linkage group was established. Conserved synteny between cattle, human, and mouse was found for 76 genes of BTA18 and human chromosomes (HSA) 16 and 19 and for 34 cattle genes and mouse chromosomes (MMU) 7 and 8. The new RH map is potentially useful for the identification of candidate genes for economically important traits, contributes to the expansion of the existing BTA18 gene map, and provides new information about the chromosome evolution in cattle, humans, and mice.

Painting of human chromosomes with probes generated from Hybrid Cell lines by PCR with Alu and L1 primers
Human Genetics, 1990Co-Authors: C. Lengauer, H. Riethman, T. CremerAbstract:Specific amplification of human sequences of up to several kb length has recently been accomplished in man-hamster and man-mouse somatic Hybrid Cell DNA by IRS-PCR (interspersed repetitive sequence — polymerase chain reaction). This approach is based on oligonucleotide primers that anneal specifically to human Alu- or L1-sequences and allows the amplification of any human sequences located between adequately spaced, inverted Alu- or L1-blocks. Here, we demonstrate that probe pools generated from two somatic Hybrid Cell lines by Alu- and L1-PCR can be used for chromosome painting in normal human lymphocyte metaphase spreads by chromosomal in situ suppression (CISS-) Hybridization. The painted chromosomes and chromosome subregions directly represent the content of normal and deleted human chromosomes in the two somatic Hybrid Cell lines. The combination of IRS-PCR and CISS-Hybridization will facilitate and improve the cytogenetic analysis of somatic Hybrid Cell panels, in particular, in cases where structurally aberrant human chromosomes or human chromosome segments involved in interspecies translocations cannot be unequivocally identified by classical banding techniques. Moreover, this new approach will help to generate probe pools for the specific delineation of human chromosome subregions for use in cytogenetic diagnostics and research without the necessity of cloning.

sensitivity of a human Hybrid Cell line hela skin fibroblast to radiation induced neoplastic transformation in g2 m and mid g1 phases of the Cell cycle
Radiation Research, 1990Co-Authors: J L Redpath, C SunAbstract:The dependence of gamma-radiation-induced neoplastic transformation frequency on position in the Cell cycle was measured for a human Hybrid Cell line (HeLa X skin fibroblast). The end point used was the induction of a tumor-associated antigen which in these Cells correlates with tumorigenicity. Induction was measured in Cells at G2, M, and mid-G1 phases and compared with the frequency induced in asynchronous Cells. For studies of Cells in G2 phase, the Cells of an asynchronous population were collected for 3 h post-irradiation using the mitotic shake-off technique. For studies of Cells in M and mid-G1 phases, Cells were collected by mitotic harvest and then treated at the appropriate time. The data show that Cells in G2 and M phase are very radiosensitive in terms of both Cell killing and induction of neoplastic transformation compared to Cells in mid-G1 or asynchronous populations. At a dose of 1 Gy, the transformation frequency was 10- to 20-fold higher for Cells in M and G2 phase than for Cells in mid-G1 or for asynchronous Cells. However, the data indicate that the transformation frequencies were similar in the different phases of the Cell cycle when correlated with surviving fraction. The results indicate that transformation frequency is more sensitive to changes in dose than is Cell survival.
