Technology Transfer Challenges in the Renewable Energy Sector
The use of fossil fuels to generate energy is often associated with serious negative effects on the environment. The greenhouse gas emissions resulting from burning these fuels destroy the ozone layer and lead to global warming. As a strategic approach to the solution of this problem, calls for research and development, as well as the implementation of technologies associated with renewable energy sources within the European Union (EU), have intensified in recent years.

Frugal Engineering
Frugal innovations are all the rage! With their genesis at grassroots levels of society, these products have evolved into Advanced Frugal Innovations (AFIs) possessing good technological sophistication. Many advanced frugal products need cutting edge research other than routine science and technology for their fruition. Frugal engineering is an important tool for tackling the challenges thrown by climate-change and other planetary and manmade crises of our time.  Frugal engineering is significant for all-round sustainable development.  Frugal engineering will increasingly impact all human endeavours, both commercial and public, for widespread sustainable development. Instances include, but not limited to, UN’s Sustainable Development Goals (SDGs), pandemic-related efforts, commercial and academic interests.  Irrespective of your field of interest or current vocation, please drop Professor Balkrishna Rao a line for your interest and/or need for research-solution using principles of frugal engineering.

The Method of 3D Printing in Clothing
Clothing is considered to be an important element of human social activities. With the increasing maturity of 3D printing technology, functional 3D printing technology can realize the perfect combination of clothing and electronic devices while helping smart clothing to achieve specific functions. Furthermore, the application of functional 3D printing technology in clothing not only provides people with the most comfortable and convenient wearing experience, but also completely subverts consumers’ perception of traditional clothing.

Molybdenum Tailings in Concrete Manufacturing
Dealingwithmineral tailings is one of themost important topics for solving the environmental problems in the mining industry. Among the techniques converting stacked molybdenum tailings to reusable cleaner products, one of the most effective ones is to use molybdenum tailings in concrete productions. The physical properties including density, microscopic structure and finesse module, and chemical composition of molybdenum tailings are similar with those of natural sand. The radionuclide assessment of molybdenum tailing meets the requirements for using as structural materials. Therefore, Molybdenum tailing is suitable to be used as the replacement of cement and fine aggregates in mortarand concrete. Based on the results of strength and duration performance comparison, the usage of molybdenum tailing as a replacement of natural sand is a more feasible way than that of ground super-fine molybdenum tailings in cement binder. It is feasible to use molybdenum tailings as fine aggregate in the preparation of structural concrete. When the amount of ground super-finemolybdenum tailings replacing cement is less than 10%, it is beneficial to improve the freeze-thaw and carbonization resistance of the concrete.

Skywell Shape in Huizhou Traditional Architecture
The skywell is a typical feature of Huizhou architecture and an important space; thus, there is the saying that “all halls are wells” . In traditional Huizhou architecture, the skywell, as a transition space between the interior and exterior, not only has positive significance for the lighting and ventilation of the building interior but also contains a lot of traditional Huizhou culture. Huizhou is famous for Huizhou merchants, who do not lack money and pay more attention to the construction of their own houses and the comfort and beauty of their houses; they set up skywells in their houses to acquire the aura of the “unity of heaven and man” and the pride of “standing on top of the sky”. On sunny days, the sun shines through the skywell to the front of the hall and the rooms, which means “sprinkling gold”; in rainy and snowy weather, rainwater flows down from the eaves around the skywell and sinks into the tank below the skywell, which means “flowing silver” and is a metaphor for wealth, also known as the “four waters to the hall”. In the skywell, combined with the through corridors and open halls, when the outdoor wind speed is high, wind pressure ventilation makes up the majority of the wind entering into the room from the skywell out, reducing the amount of indoor ventilation. When the outdoor wind is still, the skywell-shaped thermal pressure, which promotes indoor and outdoor ventilation, thus forms a complete ventilation system and plays the role of “hiding wind and gathering air”.

Recycled Concrete Aggregates Applications in Asphalt Paving
The sustainability of road pavements is highly influenced by the proper selection of the materials used in the production and construction. The material circularity principle aims to completely or partially replace traditional aggregates and fillers with wastes or by-products. Adapting asphalt mixtures to incorporate waste materials reduces the consumption of naturally mined materials, minimizing the carbon footprint and pavement industry’s impact on the environment. Furthermore, the use of waste materials minimizes landfill volumes and limits the disposal of waste produced from various sources. Thus, this document discusses the use of recycled concrete aggregates (RCA) from construction and demolition waste (CDW) as alternative aggregates for application in asphalt paving.
