Analysis of a Newly Developed Afterburner System Employing Hydrogen–Methane Blends

open access: yesInventions
A considerable number of Combined Heat and Power (CHP) systems continue to depend on fossil fuels like oil and natural gas, contributing to significant environmental pollution and the release of greenhouse gases.

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

The position of gas turbine power plants with respect to the emission of nitrogen oxides by fossil-fueled energy installations [PDF]

open access: yes
The amount of nitrogen oxides introduced into the atmosphere by gas turbines is very significant in relation to the total amount of nitrogen oxide emissions produced by chemical installations and combustion engines.

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Effect of Cycle Frequency on High Temperature Oxidation Behavior of Alumina-forming Coatings Used for Industrial Gas Turbine Blades [PDF]

open access: yes, 2004
Oxidation kinetics of platinum modified aluminide and overlay coatings on nickel base superalloys were investigated. Isothermal oxidation tests were carried out at 1050°C in synthetic air. Cyclic oxidation tests were performed with 2 cycle frequencies :

Sustainability Assessment of Circular Strategies in the Agri‐Food Industry: The Case of Olive Mills' By‐Product Valorization

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study integrates multidimensional sustainability indicators into a unified assessment approach to evaluate circular strategies in agri‐food industry businesses. This methodological approach is applied to empirically examine the case of the olive oil industry's by‐product valorization.
