Biochar from waste banana peels as growth promoter for holy basil (Ocimum tenuiflorum) and chili pepper (Capsicum annuum)

Tan N., So R.C., Ateneo de Manila University, PH

Biochars are porous materials prepared by combustion of biomass under the presence of low oxygen levels. Its application as soil fertilizer has been shown to have positive effects on the plants by increasing the fertility [...]

Poly-Paper: an Innovative Thermoplastic Eco-Composite Material Recyclable with Paper and Cardboard

Del Curto B., Politecnico di Milano, IT

Environmental, economic, technical and legislative issues can be considered drivers for the development of bio-based and/or biodegradable plastics. According to this numerous studies have been focused on the development of packaging materials based on circular [...]

Materials for Sustainability & Efficiency

Molecular Modeling of Low-Emissivity Materials

Schweizer S., Low J.J., Subramanian L., Scienomics, US

Reducing heat transfer through thermal radiation is of main importance for energy efficient building. The emissivity of a material plays a central role in this context. Using low-emissivity (low-e) building materials is a very efficient [...]

Nanostructured Calcium Silicate Phase Change Materials for Thermal Buffering in Packaging and Construction Applications

Johnston J.H., Victoria University of Wellington, NZ

This paper presents the formation and use of a novel composite nanostructured calcium silicate phase change material with significant thermal buffering capacity for use in thermally responsive packaging and construction materials. Phase change materials (PCMs) [...]

Concrete crack-healing materials using biocalcification by ureolytic bacteria isolated in marine environment: An overview

Kim H-Y, Son H.M., Lee H.K., Korea Advanced Institute of Science and Technology, KR

Micro-cracks on the surface of concrete structures frequently occur due to external force and shrinkage [1]. The deterioration of concrete durability is accelerated by the penetration of moisture and chemicals into microcracks and pores [2]. [...]

Carbon Nanotube Fiber-Based Tensegrity Structures

Zajac D., University of California-Berkeley, US

Tensegrity structures characterized by self-equilibrium and super-stability are space structures, which due to their properties are of interest to architects and civil engineers. This paper reviews the possible usage of carbon nanotube (CNT) fibers as [...]

Rapid compressive strength achievement of coal bottom ash based geopolymer by employing microwave energy

Kim H., Hong S., University of Seoul, KR

Geopolymer has been introduced as a green alternative to Portland cement to reduce CO2 from cement industry. Unlike coal fly ash, coal bottom ash has not been used widely as a source material for geopolymer [...]
