“…In Figure 4, referring to the derivative of the thermal degradation curve, it is possible to observe that the temperature at which PCL degradation rate is maximum ( T max ) is approximately 448°C. The obtained values of T i and T f in the present study varied by approximately 20°C, in relation to the studies found in the literature, which may have occurred due to the use of different heating rates and also the shape of the material, since in this work it was analyzed PCL pellets 49–51 …”

Sodium alendronate (ALD) is a bisphosphonate used to treat osteoporosis. However, its oral administration has been associated with side effects as gastroesophageal reflux. Moreover, there are some particularities for the intake of the medicine, which also hinder the patient's compliance, for example, the instruction that it has to be taken with an empty stomach, 30 to 60 min before breakfast and avoid the decubitus position after using the drug. Therefore, biomaterials for applications in osteoporotic bones are a good alternative. Thus, this work aimed to produce a Polycaprolactone (PCL) and ALD‐based powder as a supply to build biomaterials by selective laser sintering, compression molding (CM), solvent casting (SC), among others. The powder was produced by coating the ALD particles with PCL and films were produced by SC and CM techniques. The samples were characterized by Scanning Electron Microscopy, Energy‐dispersive X‐ray spectroscopy, X‐ray diffraction, Fourier transform infrared spectrometry and thermal analysis. Furthermore, the drug release was evaluated by UV–Vis spectroscopy. Results showed that ALD particles were successfully coated by PCL and applied to the production of biomaterials, highlighting its potential in the treatment of osteoporosis.

“…Soy-based adhesive has attracted more and more attention due to its advantages of easy degradation, renewable, and rich in yield. 1,2 However, soy-based adhesives have extremely low wet bonding performance due to the fact that the bonding force is only provided by intermolecular hydrogen bonds and the physical entanglement from the peptide chains, limiting the application of soy-based adhesives. In various soybased adhesives, the soy protein adhesive has the best performance but still inferior to petroleum-based resins.…”

“…In the stage of 60 to 150 • C (stage I), the thermal weightlessness rate (M SI ) was relatively low (≤5%), which was mainly caused by releasing of moisture in the adhesive, while there was no protein degradation [35]. In the stage II, the temperature was between 150 and 260 • C, the degradation behavior was mainly attributed to the unreacted micromolecular decomposition and some unstable chemical bond cleavage, including intra-/intermolecular hydrogen bonding, electrostatic bonds, and cleavage of the covalent bonding between the peptide bonds [36,37]. The degradation of protein skeleton occurred in the stage III (260-600 • C).…”

Despite the recent advances in protein-based adhesives, achieving strong adhesion and mold resistance in wet environment is challenging. Herein, a facile fabrication technology of preparing tough bio-adhesive by incorporating soybean meal and blood meal is presented. Inspired by the marine mussel byssi and brown algae, metal coordination was introduced into a loosely bound protein system to construct multiple chemical cross-linking networks. Mixed alkali-modified blood meal (mBM) was mixed with soybean meal, then 1,6-hexane dioldiglycidyl ether (HDE) and zinc ion were introduced to fabricate soybean meal and blood meal-based adhesives. The attained adhesives exhibited good thermal stability, water resistance (the wet shear strength is 1.1 MPa), and mold resistance, with appropriate solid content (34.3%) and relatively low moisture uptake (11.9%). These outstanding performances would be attributed to the reaction of 1,6-hexane dioldiglycidyl ether with protein to form a preliminary cross-linking network; subsequently, the coordination of zinc ions with amino or carboxyl strengthened and toughened the adhesive. Finally, the calcium ions gelled the adhesives, providing cohesion force and making the network structure more compact. This study realized the value-added utilization of protein co-products and developed a new eco-friendly bio-based adhesive.
