Carboxylic resins containing hydrogen or ammonium ions, taken by mouth, remove sodium ions from the gastrointestinal tract and control edema; other resins are consumed to lower acidity in the stomach and hence to soothe stomach ulcers.
Enhanced catalytic properties of CoMo/Cx/Al2O3 catalysts were related to lower acidity of CCA supports.
The lower acidity of the acid sites in SAPO-34 led to the complete utilization of the micropore space.
When the IS,min values are low, there is a greater tendency for a proton to transfer back to form the neutral acid, leading to a lower acidity and a higher pKa (Gross et al., 2001; Ma et al., 2004).
In particular, under the nonthermal O2 plasma pretreatment, the formed NO3− species lowered the acidity of ZSM5 surfaces as well as anchored the Au nanoparticles, resulting in nearly 100% selectivity toward selective oxidation instead of acid-catalyzed reactions even under high reaction temperature.
Among the three Y-zeolites, best selectivity to sym-OHA was achieved with NiHY, which has lower acidity and lower content of stronger acid sites.
Molecular dynamic simulations indicate that the interaction of isolated sulphonic acid moieties with surface silanol groups is the primary cause of the lower acidity and activity of submonolayer samples within the MCM SO3H series.
So one crucial factor to less sugar is lower acidity.
Despite lower acidity levels than in 2010, the 2011s are also fresh and lively.
Alternatively, try cold-brewed iced coffee, which has lower acidity than espresso: grind 30g coffee beans, mix with 350ml water in a cafetière, and refrigerate for 12-24 hours, depending on the coffee's strength.
