A French startup TIAMAT develops Na + ion batteries based on a sodium-vanadium-phosphate-fluoride cathode material Na 3 V 2 (PO 4) 2 F 3, which undergoes two reversible 0.5 e-/V transitions: at 3.2V and at 4.0 V. [48] A startup from Singapore, SgNaPlus is developing and commercialising Na 3 V 2 (PO 4) 2 F 3 cathode material, which shows very ...
For example, 15-crown-5 has a high affinity for sodium because the cavity size of 15-crown-5 is 1.7–2.2 Å, which is enough to fit the sodium ion (1.9 Å). [ 34 ] [ 35 ] Cryptands, like crown ethers and other ionophores , also have a high affinity for the sodium ion; derivatives of the alkalide Na − are obtainable [ 36 ] by the addition of ...
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
Sodium voltage-gated channel alpha subunit 9 (also Na v 1.7) is a sodium ion channel that, in humans, is encoded by the SCN9A gene. [5] [6] [7] It is usually expressed at high levels in two types of neurons: the nociceptive (pain) neurons at the dorsal root ganglion (DRG) and trigeminal ganglion; and sympathetic ganglion neurons, which are part of the autonomic (involuntary) nervous system.
Small granite pillars have failed under loads that averaged out to about 1.43 ⋅ 10 8 Newtons/meter 2 and this kind of rock has a sonic speed of about 5.6 ± 0.3 ⋅ 10 3 m/sec (stp), a density of about 2.7 g/cm 3 and specific heat ranging from about 0.2 to 0.3 cal/g °C through the temperature interval 100-1000 °C [Stowe pages 41 & 59 and ...
Na v 1.8 is a sodium ion channel subtype that in humans is encoded by the SCN10A gene. [5] [6] [7] [8]Na v 1.8-containing channels are tetrodotoxin (TTX)-resistant voltage-gated channels.
NaK containing 40% to 90% potassium by mass is liquid at room temperature.The eutectic mixture consists of 77% potassium and 23% sodium by mass (NaK-77), and it is a liquid from −12.6 to 785 °C (9.3 to 1,445.0 °F), and has a density of 0.866 g/cm 3 at 21 °C (70 °F) and 0.855 g/cm 3 at 100 °C (212 °F), making it less dense than water.

Sodium silicate glass-to-glass bonding has the advantage that it is a low-temperature bonding technique, as opposed to fusion bonding. [21] It also requires less processing than glass-to-glass anodic bonding, [ 23 ] which requires an intermediate layer such as silicon nitride (SiN) to act as a diffusion barrier for sodium ions.
