The methods of severe plastic deformation (SPD) have gained attention within the last decades primarily owing to their ability to substantially refine the grains within metallic materials and, therefore, significantly enhance the properties. Among one of the most efficient SPD methods is the equal channel angular pressing (ECAP)-based twist channel angular pressing (TCAP) method, combining channel twist and channel bending within a single die. This unique die affects the processed material with three independent strain paths during a single pass, which supports the development of substructure and efficiently refines the grains. This review is intended to summarize the characteristics of the TCAP method and its main features documented within the last decade, since its development in 2010. The article is supplemented with a brief characterization of other known SPD methods based on the combination of ECAP and twist extrusion (TE) within a single die.

When sng meets acupuncture -- a paradigm-shift biomarker for translational research.

The sensation of sng (pronounced/səŋ/, the Romanization form of or soreness in Taiwanese Southern Min) associated with a composite of unique sensations, is a novel phenotype for acupoint stimulation. It is perceived by test participants but also by experienced practitioners as a sensation of "taking the bait" (by fish when fishing), a characteristic heavy and tight sensation from the needle. Here, we propose that sng is a powerful biomarker for associated with successful manual acupuncture.

In this study, a supramolecular fluorescent material was constructed by using double-cavity twisted cucurbit[14]uril (tQ[14]) and positively charged Astrazon Pink FG (APFG) based on the non-covalent host-guest interaction for the first time. The thermodynamic parameters of the APFG@tQ[14] in aqueous solution were determined by isothermal titration calorimetry (ITC), the results indicated that the spontaneous assembly of APFG@tQ[14] is mainly driven by enthalpy. The intramolecular charge transfer (ICT) effect induced the APFG@tQ[14] probe to emit a strong orange-red fluorescence.

Chronic allodynia stemming from peripheral stump neuromas can persist for extended periods, significantly compromising patients' quality of life. Conventional managements for nerve stumps have demonstrated limited effectiveness in ensuring their orderly termination. In this study, we present a spatially confined conduit strategy, designed to enhance the self-organization of regenerating nerves after truncation.

Article Synopsis
- Covalent organic frameworks (COFs) are being explored for efficient hydrogen peroxide (HO) photosynthesis, but achieving high performance has been difficult due to challenges in separating photogenerated charges.
- The introduction of ethenyl group-modified bicarbazole-based COFs (COF-DH-Eth) led to a significant improvement, achieving a HO production rate of 9212 μmol g h, which is 2.5 times higher than that of non-modified COFs.
- The enhanced performance is attributed to the interaction between an ultrasonic-induced electric field and effective charge transfer pathways, indicating that the twisted structure of organic ligands is key to establishing the piezoelectric properties necessary for better hydrogen peroxide synthesis.
