Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m
Early reprogramming regulators identified by prospective isolation and mass cytometry. Nature 521, 352–356 (2015). Lujan et al . identified transcriptional activators that are associated with the induction of pluripotency but are not necessary for the maintenance of self-renewal. Article CAS PubMed ...
Figure 1 Mass/charge spectra of Ho3N@C80 ionized with laser pulses of 800 nm, 30 fs pulse duration and an intensity of 4 × 1014 W/cm2. Full size imageIn this work, we investigated the dependence of Ho3N@C80 q+ (q = 1–2) yields as a function of the peak las...
The supernatant was analyzed by gas chromatography-mass spectrometry (GC‒MS-QP2010 Ultra; Shimadzu) with the temperature program: initial temperature of 70 °C (1 min hold), increase to 160 °C at 10 °C/min, and then ramp to 240 °C at 5 °C/min. Finally, increase to 280 °C ...
In the secondary ion mass spectrometry (SIMS) studies of the thin zinc-blende GaN layers (< 5μm) we were able to sputter through the GaN layer into the GaAs substrate [45]. We have used calibration standards for As in GaN in order to quantify the As concentrations in our layers. ...

In a wide variety of bacteria, PHB is often known as a polymer of high molecular mass that constitutes a carbon store in the form of crystalline cytoplasmic granules that may constitute up to 90% of the cell’s dry weight [19]. However, a short chain form of PHB with a low molecular...
The extent to which convergent evolutionary events are a common theme in ccRCC remains to be determined, but may indicate that critical genes will be represented across the tumour landscape for an individual mass. In general, the large sample size seemed to overcome the intrinsic challenges of ...
The formation of VOCs with low molecular mass has been known since the middle of the 20th century. Recent advances in analytical methods, such as gas chromatography-mass spectrometry, allowed for the experi- mental identification of several compounds emitted during paper degradation, e.g. furfural ...
Here, ϑ(τ) denotes the momentary deviation of the lipid direction vectors from the average normal vector of the membrane plane. This vector is estimated by calculating the average center of mass of all lipids located at the four edges of the membrane, separately for both sides of the bila...
