Countries such as China are facing a bottleneck in their paths to carbon neutrality: abating emissions in heavy industries and heavy-duty transport. There are few in-depth studies of the prospective role for clean hydrogen in these ‘hard-to-abate’ (HTA) sectors. Here we carry out an integ...
In this Review, we disentangle the respective roles of the arrow of time and the non-Boltzmann nature of steady-state fluctuations in this rich phenomenology. We show that effective, time-reversible descriptions of active systems may be found at all scales and discuss how interactions, either ...
Identify the type of reaction shown in the following chemical equation. {eq}MgO(s) + CO_2(g) \to MgCO_3(s) {/eq} Reaction Types: There are hundreds of thousands of compounds (on earth) and even more in reactions such that it would not be ...
The microscopic origin of high-temperature superconductivity in cuprates remains unknown. It is widely believed that substantial progress could be achieved by better understanding of the pseudogap phase, a normal non-superconducting state of cuprates1,2. In particular, a central issue is whether the...
The point indicated by the arrow is the location of an actual casing collapse event at 3556 m in well MN#410 that occurred during April 2015 in the Marun oil field. See Fig. 19 for lithology details at point of casing collapse. Download: Download high-res image (390KB) Download: ...
