Chemically Tunable TiCT MXene Surfaces.

Modifying MXene surfaces is an effective strategy for controlling interactions with various chemical environments. Here, we demonstrate that treating TiCT MXene surfaces with dilute acids and bases results in surfaces enriched with oxygen species capable of reversible proton exchange. These treatments produce surfaces with varying dispersibilities in different organic solvents that can be toggled between "on" and "off" states through successive treatments.

Predictors of Cognitive Impairment among Filipino Patients with Type 2 Diabetes Mellitus in a Tertiary Government Hospital.

Background: Type 2 Diabetes Mellitus (T2DM) patients are predisposed to cognitive decline and dementia. The co-occurrence of the two diseases translate to a higher medical cost. Identification of factors contributing to cognitive impairment is warranted.

Chemical Treatment of Waste Abaca for Natural Fiber-Reinforced Geopolymer Composite.

The use of natural fibers in reinforced composites to produce eco-friendly materials is gaining more attention due to their attractive features such as low cost, low density and good mechanical properties, among others. This work thus investigates the potential of waste abaca (Manila hemp) fiber as reinforcing agent in an inorganic aluminosilicate material known as geopolymer. In this study, the waste fibers were subjected to different chemical treatments to modify the surface characteristics and to improve the adhesion with the fly ash-based geopolymer matrix.
