Compressibility of Calcium Nitride to 137 Kb

Origin of the low compressibility in hard nitride spinels

Compressibility and thermal expansion of cubic silicon nitride

Evidence for a low-compressibility carbon nitride polymorph elaborated at ambient pressure and mild temperature

Superhard materials like diamond are essential for abrasive or cutting tool applications. In this way, carbon nitrides are of relevant interest because they are expected to exhibit exceptional mechanical properties, high values of bulk modulus being predicted. A smart and simple method was used to synthesize carbon nitrides and allowed elaborating a low-compressibility polymorph. The processing...

128-137 Challenges to Reading

Curriculum Change in South Africa Since 1994 The development of a national curriculum is a major challenge for any nation, and when a whole country depends on it to transform society in one broad stroke, it imposes tremendous expectations on such a curriculum. South Africa’s democratic government has inherited a divided and unequal system of education and must recognise that apartheid is not th...

Kobayashi compressibility

Kobayashi [Kob81] introduced a uniform notion of compressibility of infinite binary sequences X in terms of relative Turing computations with sub-linear use of the oracle. Given f : N → N we say that X is f -compressible if there exists Y such that for each n we can uniformly compute X ↾n from oracle Y ↾ f (n). Kobayashi compressibility has remained a relatively obscure notion, with the excepti...
