The synthesis of enantiopure molecules from achiral precursors without the need for pre-existing chirality is a major challenge associated with the origin of life. We here show that an enantiopure product can be obtained from achiral starting materials in a

Multicapillary column ion-mobility spectrometry (MCC-IMS) may identify volatile components in exhaled gas. The authors therefore used MCC-IMS to evaluate exhaled gas in a rat model of sepsis, inflammation, and hemorrhagic shock. Male Sprague-Dawley rats were anesthetized and ventilated via tracheostomy

The hypothesis that endovascular treatment with covered stents has equal risks but higher efficacy than bare-metal stents (BMS) in long femoropopliteal artery disease was tested. Although endovascular treatment of short superficial femoral artery lesions revealed excellent results, efficacy in long

Highly regular NaTi2 (PO4 )3 nanocubes with synergistic nanocoatings of rutile TiO2 and carbon are prepared as an electrode material for sodium-ion batteries. It exhibits a high rate and ultralong life performance simultaneously, and a capacity retention of 89.3% after

Given the critical role of pure, organic compound primary reference standards used to characterize and certify chemical Certified Reference Materials (CRMs), it is essential that associated mass purity assessments be fit-for-purpose, represented by an appropriate uncertainty interval, and metrologically sound.

Questions

1–2 of 2 Questions  
  1. What size are the beads? Are they round?

    1 answer
    1. The shape and particle size of this product is not determined on a lot to lot basis. However, historical data indicate that the bulk of the material will have a particle size range of 250 - 840 um.

  2. How would I go about diluting this powder in order to spread out the individual beads? Obviously, I cannot use water as PTFE is hydrophobic. Will ethanol work?

    1 answer
    1. There are no known solvents which could dilute PTFE at room temperature. The surface of PTFE at room temperature is affected only by molten alkali and fluorine in some cases, this will result in dissolving PTFE but not diluting. There are commercially available PTFE aqueous dispersions available. These commercial grade products utilize non-ionic surfactants to maintain dispersion.
