Aviation Spline Research
Splines are irreplaceable in high-speed aviation fields due to their simplicity, reliability, and high specific power. Aviation splines are not only subjected to severe operating mechanical loads, but also sometimes operate under grease-lubricated and non-lubricated environments. All of this results in aviation splines suffering widespread failures.

Avocado Peel Extracts in Topical Formulations
The avocado fruit, a derivative of the avocado tree of botanical name Persea americana Mill.. Avocado peel is a cheap and promising option for the retrieval of phenolic compounds, and it was reported that this by-product possesses higher total phenolic content, radical scavenging capacity, and antioxidant activity compared to the pulp. These results highlight the possibility of obtaining sustainable cosmetics, reducing significantly the negative impacts on the environment by the incorporation of extracts sourced from the avocado peel, an  interesting source of phenolic compounds, abundant and low-cost by-product.

B-Lymphocytes in Progression to Osteoporosis
B-lymphocytes—typically appreciated for their canonical role in adaptive, humoral immunity—have emerged as critical regulators of bone remodeling. B-lymphocytes communicate with osteoclasts and osteoblasts through various cytokines, including IL-7, RANK, and OPG. In inflammatory conditions, B-lymphocytes promote osteoclast activation and differentiation. However, B-lymphocytes also possess immunomodulatory properties, with regulatory B-lymphocytes (Bregs) secreting TGF-β1 to restrain pathogenic osteoclastogenesis.

Bacteria-Based Self-Healing Concrete
Cracking is one of the main ways that concrete ages, allowing pollutants to seep within and potentially lowering the physical and mechanical strength and endurance of concrete structures. One of the healing procedures that merits research is the use of bacterially generated calcium carbonate precipitation in concrete mixtures to mend concrete cracks.
