Medically reviewed by Laura Young, MD The luteal phase of the menstrual cycle occurs from just after ovulation, when an egg is released from the ovary, to the day before menstruation. During these 12 ...

What is a phase? Middle school science class provides an introduction to phases: solids, liquids and gases, and perhaps an argument to be made for plasma. When thinking of these materials at the ...

Ammonia borane (NH3BH3) is a promising hydrogen-storage material because of its high hydrogen density. It is employed as a hydrogen source when synthesizing superconducting polyhydrides under high ...

It's the first room-temperature quantum coherence of entangled quintet-state electrons, said study co-author Yasuhiro Kobori, a professor of chemistry at Kobe University, in the statement.

We report the high-temperature and high-pressure single-crystal x-ray diffraction study of PbHfO3. The increase of pressure enables an additional intermediate phase, located between the cubic and ...

The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.

2 University of Chinese Academy of Sciences, Beijing, China The subduction of calcite into deep Earth and subsequent phase change are important for global carbon cycle. However, the study of the phase ...

Simplified ternary phase diagram for the Na2O–B2O3–SiO2 system. (Bartl et al., 2001)8. Phase separation (and consquent crystallization) can also be regulated by adding glass modifiers and by adjusting ...
