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.

A Qualitative Analysis of Social Indicators in Highly Polluting Sectors: The Challenge for Multifaceted Standards in Emerging Economies

open access: yesBusiness Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT The institutional current effort to regulate and increase the quantity and quality of sustainability information reported by companies is undeniable. However, the growing complexity of sustainability reporting standards creates isolated compartments for each major dimension of sustainability, leaving aside their interconnectedness and combined

Experimental evaluation of a diesel engine with diesel oil and fish oil blends.

open access: yes, 1998
It is proposed to use fish oil mixed with Diesel 2 oil in diesel engines, by adding it in volumetric proportion to the amount of diesel fuel. This mixture is used as an alternative fuel to reduce diesel fuel consumption; its use is low cost, which makes it feasible and convenient for use in diesel engines of small and medium power fishing boats.

Environmentally adjusted productivity growth and shadow prices for dairy farms

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.
