“…In the work of Koley et al (2016), sericin/HAp materials were used to purify water, exhibiting excellent adsorption of toxic heavy metal ions. While HAp has stability, sericin is a water-soluble material, capable of forming hydrogen bonds and with strong metal binding properties (Khosa et al, 2014).…”

Calcium phosphates (CaPs) have been widely used in the field of biomedical engineering as bone graft substitutes or as carriers for drug delivery applications. Recent developments have focused on combining CaPs with proteins to obtain functional biomaterials that accommodate a broader spectrum of functional requirements. Silk sericin was considered an unutilized protein by-product from the textile industry, generating tons of residues every year. However, much effort has been dedicated to its recovery after being associated with numerous biological properties such as antioxidant, antibacterial, anti-coagulation and regenerative activities. In the past years, sericin has also demonstrated to be suitable as a template for CaP mineralization. The present review focuses on the recent developments for the production of sericin/CaP composites, exploring their potential applications in bioengineering and opening new avenues in other research fields such as in the cosmetic, food and environmental sectors. In addition, this paper can also be useful as a guideline to design future research based on sericin/CaP biomaterials.

“…The global yearly production of sericin is about 50,000 metric tons [21]. Strong polar side groups such as hydroxyl, carboxyl, and amino groups exist in sericin due to the 18 kinds of amino acids contained in it, making sericin a low-cost biosorbent for organic dyes or heavy metal ions through electrostatic interaction or chelation [22][23][24].…”

“…As well-known, the enthalpy of fusion of ice (latent heat of fusion: 333.5 kJ/kg) is six times lower than its enthalpy of vaporization (latent heat of vaporization of water: 2256.7 kJ/kg). This means that only 420 kJ/kg of energy is required to remove salt for the production of 1 kg of fresh water, which is six times lower than what multi-stage flash desalination requires [36,37].…”

Abstract:Osmotic energy, as a sustainable energy source with little environmental impact, has drawn much attention in both academia and industry in recent years. Osmotically driven membrane processes can harvest the osmotic energy and thus have great potential to produce sustainable clean water or electric energy. The draw solution, as an osmotic component, has been more and more explored by scientists in recent years in order to achieve a high osmotic pressure and suitable molecular size. In this work, a novel draw solute-sodium tetraethylenepentamine heptaacetate (STPH)-is synthesized and identified by nuclear magnetic resonance spectroscopy ( 1 H-NMR) and Fourier transform infrared (FTIR). Its solution properties are optimized in terms of the solution pH and concentration, and related to the forward osmosis (FO) performance. A water flux of 28.57 LMH and a low solute flux of 0.45 gMH can be generated with 0.5 g/mL STPH draw solution and de-ionized water (DI water) as the feed solution under pressure retarded osmosis (PRO) mode, which is superior to the FO performance with many other draw solutes reported. Further FO desalination test shows a stable water flux of 9.7 LMH with 0.3 g/mL STPH draw solution and 0.6 M NaCl feed solution. In addition, the draw solution recovery is also investigated.
