Macroscopic quantum self-trapping and atomic tunneling in two-species Bose-Einstein condensates

open access: yes, 2000
We present a new theoretical treatment of macroscopic quantum self-trapping (MQST) and quantum coherent atomic tunneling in a zero-temperature two-species Bose-Einstein condensate system in the presence of the nonlinear self-interaction of each species ...

Thermodynamic Evaluation of Dual Substrate Growth

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Various C₁–C₂ compounds are increasingly available through electrochemical reduction of CO2. Although not always suitable as a sole substrate, these compounds can supplement a primary substrate like glucose to enhance microbial growth. Yet, the mechanisms underlying the effects of dual substrate consumption on growth rate and growth yield ...

A review of interspecies electron transfer in anaerobic digestion

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract Anaerobic digestion (AD) is an effective way to recover energy from organic waste. About 70% of the methane emitted into the atmosphere is derived from the degradation of organic matter by microorganisms under anaerobic conditions.

Interspecies Electron Transfer during Propionate and Butyrate Degradation in Mesophilic, Granular Sludge [PDF]

open access: yesApplied and Environmental Microbiology, 1995
Granules from a mesophilic upflow anaerobic sludge blanket reactor were disintegrated, and bacteria utilizing only hydrogen or formate or both hydrogen and formate were added to investigate the role of interspecies electron transfer during degradation of propionate and butyrate.

Carbon nanotubes accelerate methane production in pure cultures of methanogens and in a syntrophic coculture [PDF]

open access: yes, 2017
Carbon materials have been reported to facilitate direct interspecies electron transfer (DIET) between bacteria and methanogens improving methane production in anaerobic processes. In this work, the effect of increasing concentrations of carbon nanotubes

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Co-occurrence of Methanosarcina mazei and Geobacteraceae in an iron(III)-reducing enrichment culture

open access: yesFrontiers in Microbiology, 2015
Methanosaeta harundinacea and Methanosarcina barkeri, known as classic acetoclastic methanogens, are capable of directly accepting electrons from Geobacter metallireducens for the reduction of carbon dioxide to methane, having been revealed as direct ...

All-Optical Formation of Quantum Degenerate Mixtures

open access: yes, 2008
We report the realization of quantum degenerate mixed gases of ytterbium (Yb) isotopes using all-optical methods. We have succeeded in cooling attractively interacting 176Yb atoms via sympathetic cooling down to below the Bose-Einstein transition ...

Differential Proteomic Analysis to Reveal the Mechanism of Heat Damage in Soybean Using a Data‐Independent Acquisition (DIA) Strategy

open access: yesFood Safety and Health, EarlyView.
Heat‐stressed soybeans adapt to elevated temperatures through coordinate regulation of destructive and protective protein expression ‐ suppressing detrimental proteins while enhancing beneficial ones. ABSTRACT Soybean represents the largest imported agricultural product in China. Imported soybeans are typically transported via maritime shipping. During

Macroscopic electromagnetic stress tensor for ionized media

open access: yes, 2009
Following the arguments presented by Mansuripur [Opt. Express 16, 14821-14835 (2008)], we suggest a form for the macroscopic electromagnetic stress tensor appropriate for ionized media.
