From diffusive to ballistic transport in etched graphene constrictions and nanoribbons
, 2017 Graphene nanoribbons and constrictions are envisaged as fundamental components of future carbon-based nanoelectronic and spintronic devices. At nanoscale, electronic effects in these devices depend heavily on the dimensions of the active channel and the ...

Designing multifunctional chemical sensors using Ni and Cu doped carbon nanotubes [PDF]
, 2010 We demonstrate a "bottom up" approach to the computational design of a multifunctional chemical sensor. General techniques are employed for describing the adsorption coverage and resistance properties of the sensor based on density functional theory (DFT)

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
FEBS Letters, EarlyView.This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]
, 2014 Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is

Monitoring of the carbon footprint of road freight transport activities
Monitoring of the carbon footprint of road freight transport activities, 2023 The article analyzes the process of monitoring the carbon footprint of road freight transport. The significance of the influence of road transport on climate warming is revealed. In order to select the most appropriate method for calculating pollution with greenhouse gases, the methodology for calculating pollution is analyzed.

FEBS Letters, EarlyView.Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Organic carbon transport and impacts of human activities in the Yellow River [PDF]
Biogeosciences, 2012 Abstract. Based on four field investigations during 2003 and 2009 along the Yellow River mainstream, we examined the distributions, seasonal variations and transport features of organic carbon, with a focus on the impacts of human activities (reservoir construction and regulation scheme).
