  • Publication number: 20250101334
    Abstract: This invention relates to a diesel engine lubricating oil composition comprising or resulting from the admixing of: (i) base oil, (ii) a functionalized polymer, (iii) an overbased magnesium based detergent, and (iv) one or more, optionally borated, higher and/or lower molecular weight PIBSA-PAM dispersant. The composition has a total sulfated ash of less than or equal to 0.9 wt. %, a kinematic viscosity at 100° C. of 5 to 20 cSt, a total phosphorous level of less than or equal to 0.120 wt. %, and a total sulfur level of less than or equal to 0.35 wt. % and provides a Detroit DD-13 scuffing test result of at least 31 hours. Also provided are a method of making the composition, a method of lubricating a diesel engine, a method of improving wear performance and engine cleanliness and reducing emissions of a diesel engine, and a diesel engine oil additive concentrate composition.

  • Publication number: 20230201121
    Abstract: A drug delivery system comprises a porous, self-healing biodegradable polymer matrix having a ionic, charged, biopolymer and a pH modifying species disposed within the pores. An ionic macromolecule having the opposite charge binds the biopolymer and forms a nonsoluble polyelectrolyte complex. The molecular weight of the biopolymer, the self healing polymer matrix, the concentration of pore forming agent and the concentration of the pH modifying species are selected for optimal binding and release of the macromolecule.
