“…Further, as shown in Figure 11e, compared with previously reported ICE sensors based on LA in terms of breaking stress, stretchability, gauge factor, underwater adhesion, and underwater sensor ability, the ICE 3‐5 sensor exhibited excellent comprehensive performance, particularly its underwater performance.

“…[ 18,30–34 ] Recently, many researchers have successfully fabricated conductive elastomers based on LA. [ 10,24,25,35–39 ] Despite the excellent transparency, ionic conductivity, and self‐healing efficiency, most conductive elastomers suffer from a relatively low mechanical strength, especially stabilized LA by vinylic compounds. The metal ions (Fe 3+ and Al 3+ ) and double‐network are hence introduced into the poly(LA) network, so as to construct multiple interactions (such as coordinate covalent bonding and hydrogen bonding) to improve the mechanics.…”

Flexible wearable sensors recently have made significant progress in human motion detection and health monitoring. However, most sensors still face challenges in terms of single detection targets, single application environments, and non‐recyclability. Lipoic acid (LA) shows a great application prospect in soft materials due to its unique properties. Herein, ionic conducting elastomers (ICEs) based on polymerizable deep eutectic solvents consisting of LA and choline chloride are prepared. In addition to the good mechanical strength, high transparency, ionic conductivity, and self‐healing efficiency, the ICEs exhibit swelling‐strengthening behavior and enhanced adhesion strength in underwater environments due to the moisture‐induced association of poly(LA) hydrophobic chains, thus making it possible for underwater sensing applications, such as underwater communication. As a strain sensor, it exhibits highly sensitive strain response with repeatability and durability, enabling the monitoring of both large and fine human motions, including joint movements, facial expressions, and pulse waves. Furthermore, due to the enhancement of ion mobility at higher temperatures, it also possesses excellent temperature‐sensing performance. Notably, the ICEs can be fully recycled and reused as a new strain/temperature sensor through heating. This study provides a novel strategy for enhancing the mechanical strength of poly(LA) and the fabrication of multifunctional sensors.

“…Yet, existing studies on co-transcriptional folding of SRP RNA have been conducted mostly with the mature sequence lacking the 5 0 precursor (Wong et al, 2007). The fact that the 138-nt pre-SRP RNA is not isolated from bacteria unless the processing enzyme RNase P, which is five times less abundant, is impaired, which generates a mixture of pre-and mature products, suggests an extremely rapid or co-transcriptional maturation of SRP RNA (Altman and Kirsebom, 1999;Bothwell et al, 1976;Dong et al, 1996) Therefore, we looked into each intermediate detected along the SRP RNA folding trajectory for specific structural and sequence elements that match those recognized by RNase P, namely, a hairpin stem at least $3-4 bp in size with little to no 3 0 end single strand and a 5 0 -U À1 G +1 /C 21 R 22 -3 0 base-pairing sequence at its hairpin junction (Figure 4A) (Li et al, 2005;McKinney et al, 2001;Peck-Miller and Altman, 1991;Sinapah et al, 2011). RNase P reportedly cuts between the U À1 and G +1 to remove the 5 0 precursor and yields mature functional RNA substrates, including tRNAs (McKinney et al, 2001;Sinapah et al, 2011).…”

The paper reviews the results of using the process of self-propagating high-temperature synthesis (SHS) to obtain high-temperature nickel alloys and composites based on titanium carbide (TiC) and nickel. In order to reduce the brittleness of these composites, it was proposed to replace the TiC ceramic phase by the MAX phase of titanium silicon carbide (Ti3SiC2) and use the SHS process to obtain a Ti3SiC2–Ni skeleton composite. Nickel for Ti3SiC2skeleton infiltration was introduced in three variants: by introducing to the reaction mixture; in the form of a briquette located between two SHS charge briquettes; and similar to the second variant, but with the barrier layers of paper between the Ni and SHS charge briquettes. It was shown that Ni melt in all three variants prevents the formation of the titanium silicon carbide MAX phase thus leading to its degradation. Ni introduction into the reaction mixture according to the first variant made it possible to obtain a homogeneous composite, which became almost non-porous with an increase in Ni concentration up to 50 %. When the Ni briquette was placed between two compacted briquettes of SHS charge, it was possible to melt a relatively small amount of Ni (23–29 % of the mass of synthesized composite samples), which was not enough to completely fill the porous layered skeletons of Ti3SiC2. 20 % of Si added to the Ni briquette increased infiltration depth, lowered the degree of MAX phase degradation at the infiltration point, and formed a more homogeneous composite consisting of a porous skeleton of TiC, TiSi2and Ti3SiC2phases partially filled with metallic nickel during Ni(Si) melt infiltration.
