Sodium Bicarbonate Air-polishing

Sodium bicarbonate air-polishing is a minimally invasive dental cleaning technique that uses a pressurized spray to remove deposits and stains from tooth surfaces, making it relevant to preventive and clinical medicine. The system combines compressed air, water, and sodium bicarbonate powder, producing a directed abrasive stream that disrupts and clears plaque, biofilm, and extrinsic discoloration. Clinicians use the method for professional oral hygiene, stain removal, and surface preparation before selected dental procedures. By improving access to irregular surfaces and reducing reliance on manual instrumentation, sodium bicarbonate air-polishing can support efficient plaque control and contribute to overall oral health.

2008

This is a guide to modifying the shape of glass micropipettes. Specifically, by using heat and air pressure the taper is widened without increasing the tip opening, leading to lower pipette resistance. This is critical to obtain low noise recordings of small cells but is useful in many applications.

Roles of Electrolytes: Chloride and Bicarbonate

0 Views •

2024

Chloride ions contribute to the osmotic pressure gradient distinguishing the intracellular fluid (ICF) from the extracellular fluid (ECF). They counterbalance positively charged ions in the ECF and ensure its electrochemical stability. The renal system's process of chloride absorption and release generally mirrors that of sodium ions. Conditions such as hypochloremia can arise from insufficient chloride reabsorption by the kidneys, often compounded by extended bouts of diarrhea, vomiting, or...

Bicarbonate-Carbonic Acid Buffer

The carbonic acid-bicarbonate buffer system is critical for maintaining the body's pH balance. It operates on the equilibrium: H2CO3 ⇋ H+ + HCO3- In this system, bicarbonate ions (HCO3⁻) act as weak bases, and carbonic acid (H₂CO₃) serves as a weak acid. This dynamic equilibrium enables the system to respond effectively to changes in pH. When hydrogen ion (H+) levels increase, causing a drop in pH, the equilibrium shifts to the left, converting hydrogen ions into carbonic acid. The enzyme...

Convergent Polishing: A Simple, Rapid, Full Aperture Polishing Process of High Quality Optical Flats & Spheres

A novel optical polishing process, called “Convergent Polishing”, which enables faster, lower cost polishing, is described. Unlike conventional polishing processes, Convergent Polishing allows a glass workpiece to be polished in a single iteration and with high surface quality to its final surface figure without requiring changes to polishing parameters.
