![]() ![]() The same kind of crude information can be extracted from charge density plots, where bond paths, nuclear sites, and cage structures as in benzene molecules are associated with the critical points of the dynamical system defined by the charge density gradient, i.e., saddle points, maxima and minima, respecttively. Thus ELF provides a faithful and direct space depiction of electron distribution with no restrictions on the size or the type of the system to be probed. As discussed by Becke and Edgecombe, the local value of ELF at position indicates the probability of finding an electron at that locality given the existence of neighbouring electrons. The denominator of Equation (1), which depends on the kinetic energy, is related to the leading term in the Taylor expansion of conditional pair probability. In the absence of significant electronic populations, ELF dwindles to nullity. The electron localization function (ELF), which is inversely proportional to the square of the ratio of the kinetic energy of the system under study D and the kinetic energy characteristic of a homogeneous electron gas D h to within an additive constant of unitary magnitude, gauges electron dispersiveness at position :Īs can be seen from Equation (1), ELF equals 0.5 in the case of a metallic or jellium-like electron distribution and it approaches unity for highly localized electronic clouds. In the present article, we shall expostulate that in both cases, the bonds are essentially ionic dominated and that this ionic character is capable of explaining the mechanical properties of TiC and TiN. Despite the fact that most researchers acknowledge some ionic features in the Ti-X bonds, the generally accepted viewpoint categorizes TiC and TiN as either covalent materials or substances with mixed bonding characteristics. Their results, although not indicative of notable overall covalence, are suggestive of “dominant covalency” in TiX bonds with the exception of Ti-O bonds. In a more recent investigative endeavour, Mizuno and co-workers computed bond overlap population densities and densities of states for a host of TiX compounds (where X could be B, C, N, O, Si, P or S) using firstprinciple calculations with numerical atomic orbitals. The latter proposition is adopted in the subsequent pieces of research, since it provides an explanation for the unusual mechanical and thermal properties of TiX compounds. In an early complementary density functional theory (DFT) base study of TiC and TiN bonding, however, Blaha and co-authors suggested the possibility of a charge transfer due to orbital overlaps as an alternative mechanism pointing to covalent bonding. In their exhaustive experimental studies of TiC and TiN bonds, Dunand and collaborators reported high resolution diffraction results exploited to generate charge density plots hinting at electron transfer from metallic s and d orbitals to nonmetallic p and s orbitals, and devoid of any trace of shared electronic clouds in the interstitial regions segregating the nuclei, as is the case with ionic bonds. In contrast, the electric transport properties of TiX compounds evince sharp resemblance to metallic resistivity. ![]() Mechanical features such as high hardness and brittleness, and thermodynamic characteristics like high melting points are commonly believed to result from covalent bonding or some residual covalence in bonds of mixed nature. The mechanical, thermo-physical and dielectric properties exhibited by titanium carbide (TiC), titanium nitride (TiN) and similar titanium-metalloid (TiX) compounds, on the one hand, render the aforesaid substances appealing candidates for myriads of technological applications, and on the other hand, serve as motivation to a considerable number of investigations aiming at elucidating the nature of chemical bonds involved therein. It is also suggested that the high mechanical hardness of TiC and TiN can be explained without evoking strong covalence. ![]() Our results clearly demonstrate the dominantly ionic bonding characteristics of TiC and TiN. ![]() The ELF approach was initially validated through typical examples of covalent-bonding Diamond (C) and ionic-bonding sodium chloride NaCl. Using ab initio density functional theory calculations, the electron localization function (ELF) of typical transition metal carbide TiC and nitride TiN were computed and analyzed to reveal their nature of the chemical bonds.

This was in all but name a sacred ritual, honouring Charles as the one true king and the Church of England as the one true religion.Īnd in truth, it quickly all began to drag a little. Other faiths were restricted to either a one-line cameo or just a walk-on part. We’d been told that the king had wanted this to be a celebration of all faiths, but in reality this was a full-on Protestant extravaganza.

Prince William, Kate and their children all looked as if they were extras from a remake of Cinderella. What on earth was he doing here? He gets everywhere you don’t want him and even the royals haven’t found a way of keeping him out. Once the king and Camilla reached the abbey, a new procession made its way to the altar. This was too much lese-majesty for the occasion. Nor did we get to hear Andrew being booed. Then the cameras also forgot to broadcast the procession going through Trafalgar Square, where republican protesters were gathered. Balding pointed out all the flags of the Commonwealth countries, forgetting that many of them wanted to have their own heads of state. Out in the Mall, Clare Balding was watching a horse walk sideways while the royal coach carrying King Charles and Camilla made its way to the Abbey. Huw could barely bring himself to mention either of them. ![]() But don’t dare marry a black woman and spill the beans in your autobiography.

President Macron wandering in, totally at home. The US president never attends these kinds of dos. Jill Biden and her granddaughter near the back. He didn’t know which was which but few do.

The age of pregnancy can also be estimated by measuring the levels of hCG (Human Chorionic Gonadotropin) in the mother's blood. Several situations including the following: LMP is not known or is not certain, birth control pills were taken in the two months before LMP, the menstrual cycle is irregular, you are carrying multiples (twins or more).Īlthough the age of pregnancy based on ultrasound measurements is more accurate than the age of pregnancy based on LMP, both are estimates and not definitive statements. Your pregnancy may also be dated by ultrasound measurement if an LMP formula was not appropriate for your pregnancy for any reason. Significant difference between gestational age according to LMP and gestationalĪge according to the ultrasound, you may be given a new gestational age and dueĭate based on the ultrasound measurements. Measured and the age of pregnancy is estimated by comparing baby's size against recorded averages. Ultrasound in the first trimester is the most accurate method of dating *LMP date may be adjusted if unknown or following ultrasound.Įach of these methods will give you the gestational age of your pregnancy. LMP + Time Passed = How Far Along I Am (Gestational) The age of pregnancy may be revised following your The LMP formula is good for working out an initial age of pregnancy but Historically, the first day of the last menstrual period (LMP) became the date from which pregnancy is counted even though conception occurs about two weeks later. Pregnancy is counted from a women's last menstrual period because the start of a period is easily observable and usually known to a woman whereas theĭate of conception is much less likely to be known. Why Pregnancy is Counted from the Last Menstrual Period (LMP) Read more about ultrasound on this page or ourĭue date page. This initial estimation may then be superseded or confirmed by an ultrasound. Generally, obstetricians or physicians initially calculate pregnancy from your last period without adjusting for an irregularĬycle length. Irregular menstrual periods are generally calculated by early ultrasound. One for you, most likely based on ultrasound measurements. If you don't have a valid last menstrual period date for any reason, your doctor will provide (270 days) to 41 weeks and three days (290 days) with a probability of 70%.
