The influence of surface composition of carbon nanotubes on the photobioelectrochemical activity of thylakoid bioanodes mediated by osmium-complex modified redox polymer

A combination of photosynthetic biocatalysts with high surface area conductive materials mediated by an osmium-complex modified redox polymer (OsRP)holds promising features for the development of sustainable “green” systems for solar energy conversion. In this work we performed a comparative study of two types of carbon nanotubes (CNTs)synthesized by pyrolysis of polymeric precursors. Both CNTs w

The mirror-based eyes of scallops demonstrate a light-evoked pupillary response

Light levels in terrestrial and shallow-water environments can vary by ten orders of magnitude between clear days and overcast nights. Light-evoked pupillary responses help the eyes of animals perform optimally under these variable light conditions by balancing trade-offs between sensitivity and resolution [1]. Here, we document that the mirror-based eyes of the bay scallop Argopecten irradians an

Do forest biorefineries fit with working principles of a circular bioeconomy? A case of Finnish and Swedish initiatives

Pursuit of the Bioeconomy (BE) and the Circular Economy (CE) is high on the political agendas of many countries. Application of the concepts is intended to ameliorate a number of sustainability challenges, such as raw material constraint concerns and global warming. The concepts of BE and CE are increasingly combined to describe a ‘circular bioeconomy’ (CBE), which emphasises value retention for r

Lifecycle profit analysis of prefabricated multi-active façades

Purpose: The purpose of this paper is to identify appropriate concepts of multi-active façades for the renovation of multifamily buildings in Sweden and to determine which, if any, are financially viable. Design/methodology/approach: A lifecycle profit (LCP) analysis was used to examine financial viability through a ten-step process, which included identifying concepts, assessing costs and prices,

Evolving charge correlations in a hybrid model with both hydrodynamics and hadronic Boltzmann descriptions

Background: Correlations from charge correlation, known as charge balance functions, provide critical tests of the chemical evolution of matter in a heavy-ion collision. Comparisons of experimental balance functions with calculations from parametric descriptions of the final state suggest that the charge production in the earliest stages of a heavy-ion collision are consistent with having generate

On Whitham's conjecture of a highest cusped wave for a nonlocal dispersive equation

We consider the Whitham equation u t +2uu x +Lu x =0, where L is the nonlocal Fourier multiplier operator given by the symbol m(ξ)=tanh⁡ξ/ξ. G. B. Whitham conjectured that for this equation there would be a highest, cusped, travelling-wave solution. We find this wave as a limiting case at the end of the main bifurcation curve of P-periodic solutions, and give several qualitative properties of
