Structured program for the development of compact jet engines for unmanned vehicles [PDF]

open access: yes, 1994
A case is made out for embarking upon an ab-initio design of expendable but compact jet engine gas turbine. Application areas in defence sector are explored and the timely need for this developmental programme is established.

Think Global, Act Local? Fortune 500 Business Strategies for Sustainable Cities and Communities (SDG 11)

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The role of business towards achieving the 17 Sustainable Development Goals (SDGs) has been well established. However, SDG contextualization continues to pose a conundrum, particularly for firms operating in multiple contexts. This becomes even more problematic in the case of SDG 11, the only goal in the sustainable development agenda directly

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

open access: yesChemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants

open access: yesChemie Ingenieur Technik, EarlyView.
The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.
