Human gustatory system recognizes salty/sour or sweet tastants based on their different ionic or nonionic natures using two different signaling pathways. This suggests that evolution has selected this detection dualism favorably. Analogically, this work constructs herein bioinspired stimulus‐responsive hydrogels to recognize model salty/sour or sweet tastes based on two different responses, that is,...
Lithium–sulfur (Li–S) batteries hold the superiority of eminent theoretical energy density (2600 Wh kg−1). However, the ponderous sulfur reduction reaction and the issue of polysulfide shuttling pose significant obstacles to achieving the practical wide‐temperature operation of Li–S batteries. Herein, a covalent organic nanosheet‐wrapped carbon nanotubes (denoted CON/CNT) composite is synthesized...
This work reports a portable, origami‐type paper device with a plasmonic fluor‐labeled microneedle sensing module for the multiplexed quantification of anemia biomarkers in whole blood. Sequential steps, including serum separation, target enrichment, and multiplexed readout by a gel imager, are rapidly accomplished with the flexible and highly integrated device. The microneedle array enabled efficient...
Carbon materials, as promising anode candidates for K+ storage due to their low cost, abundant sources, and high physicochemical stability, however, encounter limited specific capacity and unfavorable cycling stability that seriously hinder their practical applications. Herein, a feasible strategy to tailor and stabilize the nitrogen species in unique P/N co‐doped disk‐like carbon through the Sn incorporation...
Inspired by the action and healing process from living organisms, developing deployable devices using stimuli‐responsive materials, or “smart” deployable devices, is desired to realize remote‐controlled programmable deformation with additional in situ repair to perform multiple tasks while extending their service life in aerospace. In this work, a photoorganizable triple shape memory polymer (POTSMP)...
Wearable sensors have gained much attention due to their potential in personal health monitoring in a timely, cost‐effective, easy‐operating, and noninvasive way. In recent studies, nanomaterials have been employed in wearable sensors to improve the sensing performance in view of their excellent properties. Here, focus is mainly on the nanomaterial‐enabled wearable sensors and their latest advances...
In article number 1902881, Liang Shi, Jianming Li, Genqiang Zhang, and co‐workers achieve the designed formation of hybrid nanoboxes composed of carbon protected CoSe2 nanoparticles strongly coupled with nitrogen‐doped carbon skeleton (denoted as CoSe2@C∩NC) via a template assisted refluxing process followed by conventional selenization treatment, which enables excellent electrochemical performance...
Research on sodium‐ion batteries (SIBs) has recently been revitalized due to the unique features of much lower costs and comparable energy/power density to lithium‐ion batteries (LIBs), which holds great potential for grid‐level energy storage systems. Transition metal dichalcogenides (TMDCs) are considered as promising anode candidates for SIBs with high theoretical capacity, while their intrinsic...
The intensity ratio of the 2D band to the G band, I2D/IG, is a good criterion in selecting high quality monolayer graphene samples; however, the evaluation of the ultimate value of I2D/IG for intrinsic monolayer graphene is a challenging yet interesting issue. Here, an interesting tension‐induced Raman enhancement phenomenon is reported in supported graphene membranes, which show a transition from...
