Chloride Ions: Essential Agents for Achieving Spontaneous Delamination of MXene

open access: yesAdvanced Materials, EarlyView.
This work first identifies chloride ions as essential agents for spontaneous MXene delamination. Without Cl−, etched Ti3C2Tx remains multilayered; with Cl−, interlayer modification enables Li+ intercalation and osmotic swelling. The SPEED process couples HF‐assisted Al extraction, Cl−‐mediated interlayer expansion, and Li+‐driven swelling to produce ...

Thermal influences on spontaneous rock dome exfoliation

open access: yes, 2018
Rock domes, with their onion-skin layers of exfoliation sheets, are among the most captivating landforms on Earth. Long recognized as integral in shaping domes, the exact mechanism(s) by which exfoliation occurs remains enigmatic, mainly due to the lack ...

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

open access: yesAdvanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

About residual stresses after rolling and exfoliation of two-ply stripe

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2010
The residual stress definition problem was solved for stripe after rolling in one mill. Lengthwise residual stresses are basic cause of the defect initiation of stripe geometry of the buckles or corrugation type. Lengthwise residual stresses exist in the
