Physical properties

This study examined the physical and microbial properties of the breadfruit flour over a 16-week storage period at 25°C. Four packaging materials, including high- and low- density polyethylene (HDPE and LDPE), polyamide (PA), and polyamide/aluminum (PAAl), were used.

Metal forming to make large parts, take large reductions, use high strength materials, work to net shape (precision flashless closed die forging), and use cold forming to obtain certain physical properties all require high forming forces. These forces may be larger than the capacity of existing machinery.

Solubility parameters of carbon quantum dots (CQDs) are important physical properties to deploy CQDs in various applications such as organic light emitting diodes (OLEDs), light-converting materials in LEDs, and photoluminescent sensors for metal ion detection. Because of the low toxicity and tunable emission most CQDs have been designed to be water-soluble and biocompatible; oilsoluble CQDs that are essential for OLEDs are not yet explored.
