Desulfurization of 2-phenylcyclohexanethiol over transition-metal phosphides
2-Phenylcyclohexanethiol Cycloalkyl C-S bond Desulfurization Ni2P MoP WP Transition-metal phosphosulfide Piperidine
2023/6/19
The desulfurization of 2-phenylcyclohexanethiol (2-PCHT) was studied over Ni2P, MoP, and WP under 4.0 MPa H-2 or Ar at 240 degrees C. The hydrodesulfurization of 2-PCHT proceeded through three paralle...
Framatome has completed the development of the main component of innovative monolithic molybdenum-uranium (U-Mo) fuel for the FRM II research reactor at the Technical University of Munich (TUM). Local...

Former White House climate adviser Gina McCarthy brought her characteristic brand of climate optimism and pragmatism — tinged with humor and topped with a call to action — to Harvard on Wednesday, say...
Swift and significant gains against climate change require the creation of novel, environmentally benign, and energy-efficient materials. One of the richest veins researchers hope to tap in creating s...
In a world powered increasingly by clean energy, drilling for oil and gas will gradually give way to digging for metals and minerals. Today, the “critical minerals” used to make electric cars, solar p...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Existence of phase transition for percolation using the Gaussian Free Field
高斯自由 伯努利渗透 相变存在
2023/5/8
In this talk, we prove that Bernoulli percolation on graph undergoes a non-trivial phase transition if the graph has bounded degrees and random walk on the graph has a heat kernel with rapid decay. Th...

When temperature changes, many materials undergo a phase transition, such as liquid water to ice, or a metal to a superconductor. Sometimes, a so-called hysteresis loop accompanies such a phase change...
Burial depth interval of the shale brittle–ductile transition zone and its implications in shale gas exploration and production
Shale Brittleness Fracture Overconsolidation ratio (OCR) Confining pressure
2018/4/2
Brittleness and ductility of shale are closely related to shale gas exploration and production. How to predict brittleness and ductility of shale is one of the key issues in the study of shale gas pre...
Diet quality of US adolescents during the transition to adulthood: changes and predictors

Background: Influences on diet quality during the transition from adolescence to adulthood are understudied.
Turbo codes: the phase transition
Turbo code noise channel disordered spin model the stability threshold
2015/8/21
Turbo codes are a very efficient method for communicating reliably through a noisy channel. There is no theoretical understanding of their effectiveness. In Ref. [1] they are mapped onto a ...
