The role of fluorine-containing ultra-thin layer in controlling boron thermal diffusion into silicon
Journal of Telecommunications and Information Technology, 2023 We have investigated the influence of silicon dioxide reactive ion etching (RIE) parameters on the composition of the polymer layer that is formed during this process on top of the etched layer, and finally, the role of this layer in high- temperature ...

Gas Diffusivity in the Forest Humus Layer
Soil Science, 2019 While several diffusivity models have been developed for mineral soils, there are few data for the forest humus layers that overlie, and are distinct from, the mineral soil. We measured soil gas diffusivity of the organic layer of spruce and beech stands.

Formation of the diffusion layer in gas boring
IOP Conference Series: Materials Science and Engineering, 2018 © Published under licence by IOP Publishing Ltd. Boriding in powder media is successfully used to increase the life of parts. To increase the depth of the diffusion layer and improve its properties, a method for activating the surface of a saturable part by means of electromechanical processing is proposed. The results on the structure of the resulting

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer
Molecular Oncology, EarlyView.Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.
