Particle size-distributions Sample Clauses

Particle size-distributions. In D2.10, several methods were assessed for quantification of particle size-distributions according to the EC recommended definition of a NM. It was concluded that electron microscopy was the most suitable technique for sizing the minimum particle diameter size-distribution of a NM sample. A suite of thoroughly tested SOPs were been developed to enable production of comparable results. The SOPs include sample preparation methods, imaging methods, image analysis, and data-treatment. The SOPs were all applied on near-spherical and fractal-like MNM in an inter-laboratory comparison test using up to 9 different laboratories. The results showed that all materials could be sized quantitatively with in most cases with less than 10% uncertainty. It should be mentioned that the relative uncertainty is expected to vary with size and the morphological complexity of the materials. It was found that the sample preparation was the most critical step to enable a good analysis and that a full quantification following the established SOPs can be done with reasonable work-effort using semi-automatic analysis. There are on-going developments to enable higher levels of automation, which will reduce the time for analysis even further. WP2 did not specifically test SOPs for sizing flakes and fibrous NM. SOPs based on Scanning Electron Micoscopy -imaging were applied for fibers and tubes (nanocellulose and carbon nanotubes). Whereas fibrous objects that can be dispersed can be sized for both length and diameters, it is still not possible to provide good quantitative length data for entangled materials. This challenge may be solved by improved sample preparation techniques. The quantitative measurement of fibers, entangled fibers and odd structures should be considered in future work. Whereas, electron microscopy techniques are technologically well advanced, there are still challenges in accurate sizing around the lower end of the nanoscale. The application of Atomic Force Microscopy (AFM) for sizing flakes should also be considered in future research. A tiered approach applying also other techniques (e.g., mass spectrometry methods) for sizing very small nanoparticles around 1 nm-size may also need to be considered.

  • Distributions Generally (a) Subject to Section 7.01 respecting the final distribution on the Certificates, on each Distribution Date the Trustee or the Paying Agent shall make distributions in accordance with this Article V. Such distributions shall be made by check mailed to each Certificateholder's address as it appears on the Certificate Register of the Certificate Registrar or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date by any Certificateholder owning an aggregate initial Certificate Principal Amount of at least $1,000,000, or in the case of a Class of Interest-Only Certificates or Residual Certificate, a Percentage Interest of not less than 100%, by wire transfer in immediately available funds to an account specified in the request and at the expense of such Certificateholder; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Certificate Registrar's Corporate Trust Office; provided, further, that the foregoing provisions shall not apply to any Class of Certificates as long as such Certificate remains a Book-Entry Certificate in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Wire transfers will be made at the expense of the Holder requesting such wire transfer by deducting a wire transfer fee from the related distribution. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of each REMIC and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Certificate Registrar's Corporate Trust Office. If any payment required to be made on the Certificates is to be made on a day that is not a Business Day, then such payment will be made on the next succeeding Business Day. (b) All distributions or allocations made with respect to the Certificateholders within each Class on each Distribution Date shall be allocated among the outstanding Certificates in such Class equally in proportion to their respective initial Class Principal Amounts or initial Class Notional Amounts (or Percentage Interests).

  • Certain Distributions If the Company elects to: (I) distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued pursuant to a stockholder rights plan prior to separation of such rights from the Common Stock) entitling them, for a period of not more than 60 calendar days after the date such distribution is announced, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced (determined in the manner set forth in the third paragraph of Section 5.05(A)(ii)); or (II) distribute, to all or substantially all holders of Common Stock, assets or securities of the Company or rights to purchase the Company’s securities (other than rights issued pursuant to a stockholder rights plan prior to separation of such rights from the Common Stock), which distribution per share of Common Stock has a value, as reasonably determined by the Company in good faith, exceeding 10% of the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before the date such distribution is announced, then, in either case, (x) the Company will send written notice of such distribution, and of the related right to convert Notes, to Holders, the Trustee and the Conversion Agent at least 50 Scheduled Trading Days before the Ex-Dividend Date for such distribution; and (y) once the Company has sent such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend Date and the Company’s announcement that such distribution will not take place; provided, however, that the Notes will not become convertible pursuant to clause (y) above (but the Company will be required to send notice of such distribution pursuant to clause (x) above) on account of such distribution if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder, in such distribution without having to convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the record date for such distribution; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date; provided, further, that if the Company is then otherwise permitted to settle conversions of Notes by Physical Settlement (and, for the avoidance of doubt, the Company has not elected another Settlement Method to apply, including pursuant to Section 5.03(A)(i)), then the Company may instead elect to provide such notice at least ten Scheduled Trading Days before such Ex-Dividend Date, in which case (x) the Company must settle all conversions of Notes with a Conversion Date occurring on or after the date the Company provides such notice and on or before the Business Day immediately before the Ex-Dividend Date for such distribution (or any earlier announcement by the Company that such distribution will not take place) by Physical Settlement; and (y) such notice must state that all such conversions will be settled by Physical Settlement; provided, further, that, notwithstanding anything to the contrary in this Section 5.01(C)(i)(3)(a), in the case of any separation, from the Common Stock, of rights issued pursuant to a stockholder rights plan as set forth in clauses (I) and (II) above, in no event will the Company be required to provide such notice before the Business Day after the date the Company becomes aware of the event causing such separation.
