Energy use and Green house gas emission in organic agriculture [PDF]

open access: yes, 2008
Reduction of fossil energy use has a two-fold aim namely reducing the dependence of a limited, non-renewable resource and reduction of emissions of green house gasses (GHG).

Harnessing Macromolecular Crowding of Proteins for Engineering Sustainable Nanofiltration Membranes

open access: yesSusMat, EarlyView.
Novel biodegradable and solvent‐resistant nanofiltration membranes fabricated by harnessing the macromolecular crowding of zein protein induced by solvent interactions. Scattering experiments and molecular dynamics simulations confirmed the macromolecular crowding formation and revealed the structural characteristics of the membranes.

Characteristics and operational control strategies of grid‐forming long‐/short‐duration energy storage systems: A review

open access: yesEnergy Conversion and Economics, EarlyView.
Abstract Energy storage systems (ESSs) are increasingly critical for maintaining the stability and flexibility in power systems with rising renewable penetration. Grid‐forming (GFM) ESSs have emerged as a pivotal technology, capable of providing essential voltage and frequency support by establishing grid references in converter‐dominated systems. This

Is photovoltaic power a cost-effective energy solution for rural peoples in western Sudan? [PDF]

open access: yes, 2006
Sudan like most poor countries suffers from a deficiency in the supply of electrical power, especially for rural areas. Less than 10% of the total population, can benefit from the national grid connection.

‘CLOSING THE CARBON LOOP’: Climate Policy Discourses and the Material Politics of Municipal Waste‐to‐Biofuel Programs

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Waste‐to‐biofuel (WTB) programs have gained popularity as a municipal circular economy and an emissions reduction strategy. The upgrading of biofuels to renewable natural gas (RNG) has drawn particular interest, as RNG can displace conventional fossil fuels in any existing natural gas end use and be delivered through existing pipeline ...

Development of hybrid force-position controller for ultrasound-guided breast biopsy robotic system [PDF]

open access: yes, 2018
Conventional ultrasound-guided breast biopsy (UGBB) procedure is commonly performed to assess abnormal masses within the breast. It requires a radiologist to handle multiple devices at once, which could reduce the abilities in performing such procedure ...

Consumers' Willingness to Pay for Solar Fuel Adoption in Quebec, Canada: Evidence From a Discrete Choice Experiment

open access: yesThe American Journal of Economics and Sociology, EarlyView.
ABSTRACT This study investigates consumer preferences for renewable fuels in Quebec, with a particular focus on a solar fuel produced through artificial photosynthesis. Using a discrete choice experiment (DCE) and both conditional logit (CL) and random parameters logit (RPL) models, we estimate marginal willingness to pay (MWTP) for key fuel attributes,
