Mechanically Interlocked Hydrogel–Elastomer Hybrids for On‐Skin Electronics

Soft electronics that seamlessly interface with skin are of great interest in health monitoring and human–machine interfaces. However, achieving mechanical softness, skin adhesiveness, and high conductivity concurrently has always been a major challenge due to the difficulty in bonding dissimilar materials while retaining their respective properties. Herein, the mechanically interlocked hydrogel–elastomer hybrid is reported as a viable solution to this problem. Hydrogels with low moduli and high adhesiveness are employed as the substrate, while porous elastomer webs are used as matrices to load conductive films and lock the hydrogels through a mechanically interlocked structure. The bonding strength between the hydrogel and elastomer in the interlocking hybrid structure is 14.3 times of that obtained via the physical stacking method. As a proof of concept, interlocking hybrids are used as on‐skin electrodes for electrophysiological signal recording including electromyography and electrocardiography. The robust hybrid electrodes are able to detect signals after multiple cycles. The proposed strategy not only is an effective approach to achieve interlocking structures, but also provides a new perspective for soft and stretchable electronics.     

Reinvestigation of the high spin states in ^（161）Er and enhanced E1 transitions in the N=93 isotones

High-spin states in 161Er have been studied experimentally using the 150Nd（16O, 5n） reaction at a beam energy of 86 MeV. The relatively enhanced E1 transitions between the 5/2＋[642] and 3/2-[521] bands are observed in 161Er, and the B（E1） values are extra

The Beneficial Influence of Enzymatic Scouring on Cotton Properties

Abstract

Enzymatic scouring has been investigated for over two decades as an environmentally friendly process. Replacement of harsh alkalis by enzymes minimizes not only the COD and BOD in effluents, but also the amount of effluents, because the rinsing step may be omitted. However, advantages of enzymatic scouring on treated fabrics should also be highlighted. The benefits provided by enzymatic scouring are introduced in this paper. Enzymatic scouring was conducted under optimized conditions established previously. The weight loss, damage to fiber surface, softness, and pilling tendency of enzymatically treated fabrics were measured and compared with alkali scoured fabrics. Furthermore, K/S values of the scoured and dyed fabrics were measured before and after a number of washes in order to investigate the effect of residual enzymes on dye-ability and colorfastness.
