MoS nanosheets on plasma-nitrogen-doped carbon cloth for high-performance flexible supercapacitors.

With the surging demand for flexible and portable electronic devices featuring high energy and power density, the development of next-generation lightweight, flexible energy storage devices is crucial. However, achieving the expected energy and power density of supercapacitors remains a great challenge. This work reports a facile plasma-enabled method for preparing supercapacitor electrodes made of MoS nanosheets grown on flexible and lightweight N-doped carbon cloth (NCC).

Probing the Migration of Free Radicals in Solid and Liquid Media via Cr(VI) Reduction by High-Energy Electron Beam Irradiation.

To probe the migration of free radicals (FRs), the reduction behaviours of hexavalent chromium (Cr(VI)) in water and ice by high-energy electron beam (HEEB) irradiation were investigated. Interestingly, the reductive efficiency (RE) of Cr(VI) in water was appreciably higher than that in ice. Thus, it was proposed that the migration ability of FRs in water is distinctly higher than that in ice, likely because the migration performance of FRs is closely related to the intermolecular distance of water molecules.

Waste Carton-Derived Nanocomposites for Efficient Removal of Hexavalent Chromium.

A new nanocomposite (SCZ), microspherical carbon (SC) loaded with nanoscale zerovalent iron (ZVI), was fabricated to efficiently remove hexavalent chromium (Cr(VI)) in water. Therein, SC was derived from waste carton through hydrothermal treatment after pretreatment of removing hemicellulose and lignin, and the optimal hydrothermal conditions (200 °C, hydrothermal time of 12 h) for the preparation of SC were obtained. Subsequently, SC could effectively load ZVI nanoparticles which displayed high dispersion on the surface of SC and in the pores among SC particles owing to steric hindrance effect.

Spatial function of the oxidative DNA damage response in radiation induced bystander effects in intra- and inter-system of .

Though the signaling events involved in radiation induced bystander effects (RIBE) have been investigated both and , the spatial function of these communications, especially the related signaling pathways, is not fully elucidated. In the current study, significant increases of DNA damage were clearly observed in germline upon irradiation to both intra-system of posterior pharynx and inter-system of vulva, in which more severe damage, even to F1 generation worms, was shown for vulva irradiation. Spatial function assay indicated the DDR key components of were indispensable in germ cells for both sites irradiation, while those components in somatic cells were either not () or partially () required to promote apoptosis.

Interaction between Radioadaptive Response and Radiation-Induced Bystander Effect in Caenorhabditis elegans : A Unique Role of the DNA Damage Checkpoint.

Although radioadaptive responses (RAR) and radiation-induced bystander effects (RIBE) are two important biological effects of low-dose radiation, there are currently only limited data that directly address their interaction, particularly in the context of whole organisms. In previous studies, we separately demonstrated RAR and RIBE using an in vivo system of C. elegans .

Radioadaptive Response for Reproductive Cell Death Demonstrated in In Vivo Tissue Model of Caenorhabditis elegans.

Reproductive cell death (RCD) occurs after one or more cell divisions resulting from an insult such as radiation exposure or other treatments with carcinogens or mutagens. The radioadaptive response for RCD is usually investigated by in vitro or in vivo clonogenic assay. To date, this has not been demonstrated in the vulval tissue in Caenorhabditis elegans ( C.

Radiation-induced bystander signaling from somatic cells to germ cells in Caenorhabditis elegans.

Recently, radiation-induced bystander effects (RIBE) have been studied in mouse models in vivo, which clearly demonstrated bystander effects among somatic cells. However, there is currently no evidence for RIBE between somatic cells and germ cells in animal models in vivo. In the current study, the model animal Caenorhabditis elegans was used to investigate the bystander signaling from somatic cells to germ cells, as well as underlying mechanisms.

Targeted irradiation of shoot apical meristem of Arabidopsis embryos induces long-distance bystander/abscopal effects.

Bystander effects induced by low-dose ionizing radiation have been shown to occur widely in many cell types and may have a significant impact on radiation risk assessment. Although the region of radiation damage is known to be much greater than the initial target volume irradiated, it remains to be seen whether this response is limited to the specific organ irradiated, spans a limited region of the body, or even covers the whole body of the target. To determine whether long-distance bystander/abscopal effects exist in whole organisms and to clarify the problem of intercellular communication, in the present study a specific cell group, the shoot apical meristem in Arabidopsis embryo, was irradiated with a defined number of protons and examined for root development postirradiation.

Velocity of polymer translocation through a pore.

We theoretically study the translocation time and the mean velocity of a long polymer threading a long nanopore on an external electric field. Theoretical method, which explicitly takes into account the nucleation theory, is presented based on the built polymer expanded model. We overcame the previous theory's defect which did not consider the real length of the pore.
