traffic and crossed the bridge into the Commonwealth or wherever we call home.Īs far as EOD, I view that as marking the day as a whole, meaning 11:59 PM prior to the clock striking midnight and a new calendar day beginning. For many of us, until March 2020, that was about the time we got a drink with a peer or new business prospect or began the trudge home in D.C.
PST NUCLEAR TIME PROFESSIONAL
That means that greater clarity on who is assigned to what and when the service will be performed and/or product delivered, is even more important, as in-person team meetings and popping into someone’s office is largely nonexistent. Follow-up requires a call, text, email, Slack, etc.Īs far as COB, I view the close of business as the traditional time when professional employers cease operation and the markets have already ended regular trading hours. In today’s business world with people tethered to their iPhones and working remotely, the traditional time stamps for the average business day have been blurred more so than they were pre-COVID. I find people tend to use either or both interchangeably, and in my mind, it can lead to miscommunication on occasion. I believe there is a clear difference between COB and EOD.
PST NUCLEAR TIME PLUS
Therefore, a couple members of the PLUS team weighed in with their views on this matter for the sake of airing it out. The vernacular is often used interchangeably without much thought to whether there is a distinction between the two. In meetings, previously in-person and now over Zoom, someone would routinely say to another colleague or client, we will get the document, creative, research or plan to you by close of business (COB) or end of day (EOD).

Production of polyhydroxyalkanoates: The future green materials of choice. Several NMR parameters were beneficial for analyzing the manufacturing process as the indexes of polymer compatibility and molecular motions.Ĭopolymerization inedible biomass nuclear magnetic relaxation plasticization polyester solid-state nuclear magnetic resonance (NMR) variable temperature measurement.Īkaraonye E., Keshavarz T., Roy I. Slow molecular motions (kHz order) were enhanced more by the addition of PBS than PLA, although rapid molecular motions (MHz order) were enhanced by either polyester. Meanwhile, the decrease of T₁C values was dominated by increasingly rapid molecular motions of PHB because of the lowered crystallinity due to the plasticization. A variable temperature relaxation time analysis showed that the decrease of T₁H values was dominated by the ¹H spin diffusion via the interface between PHB and the added polyester because of the good compatibility.
Both the signals of ¹H MAS (magic-angle spinning) and 13C PST (pulse saturation transfer) MAS nuclear magnetic resonance (NMR) spectra were sharpened and increased by copolymerization with PBS. For the case of a poly(3-hydroxybutyrate) (PHB) unit in plasticized PHA, copolymerization of either PBS or PLA decreased ¹H and 13C spin-lattice relaxation times in the laboratory frame ( T₁H and T₁C) in the same manner, while PBS produced a lower ¹H spin-lattice relaxation time in the rotating frame ( T₁ ρH) than PLA. The molecular mobility and compatibility of plasticized polyhydroxyalkanoates (PHA) were investigated, focusing on changes due to copolymerization using either flexible poly (butylene succinate) (PBS) or rigid poly(lactic acid) (PLA) units.
