Pulmonary arterial hypertension (PAH) is a severe medical condition characterized by elevated blood pressure in the pulmonary arteries. Nitric oxide (NO) is a gaseous signaling molecule with potent vasodilator effects; however, inhaled NO is limited in clinical practice because of the need for tracheal intubation and the toxicity of high NO concentrations. In this study, inhalable NO‐releasing microspheres...
Phase‐change random‐access memory is a promising non‐volatile memory technology. However repeated phase‐change operations can cause durability issues owing to defects formed by long‐distance atom diffusion. To mitigate these issues, phase‐change heterostructure (PCH) devices with confinement material (CM) layers based on transition metal dichalcogenides (TMDs) such as TiTe2 have been proposed. This...
Phase‐Change Heterostructure Memory
In article number 2303659, Tae Geun Kim and co‐workers present phase‐change heterostructure (PCH) memory devices that control vertical atomic diffusion during operation. The device performance, such as power consumption and thermal stability, is determined by the choice of transition metal dichalcogenide‐based confinement materials with different cohesive energies,...
Phase‐Transition Ion Gels
In article number 2301868, Hong Chul Moon and co‐workers report highly deformable and thermo‐responsive ion gels produced by simply blending PS‐r‐PnBMA (copolymer gelator) and [BMI][TFSI] (ionic liquid). The functional gel‐based sensory platforms can successfully recognize thermal and mechanical environmental changes through variations in the optical (transmittance) and electrical...
Wearable ionoskins are one of the representative examples of the many useful applications offered by deformable stimuli‐responsive sensory platforms. Herein, ionotronic thermo‐mechano‐multimodal response sensors are proposed, which can independently detect changes in temperature and mechanical stimuli without crosstalk. For this purpose, mechanically robust, thermo‐responsive ion gels composed of...
Lithium–Sulfur Batteries
In article number 2200326, Kang‐Jun Baeg, Jun‐Woo Park, an co‐workers develop high‐energy‐density flexible lithium–sulfur (Li–S) batteries with high‐loading, free‐standing cathodes and chemically functionalized carbon mixture interlayers. The multimodal capturing effect via simultaneous physical trapping and strong chemical interactions is highly efficient for immobilizing...
The widespread adoption of Li‐ion batteries is currently limited by their unstable electrochemical performance and high flammability under mechanical deformation conditions and a relatively low energy density. Herein, high‐energy‐density lithium–sulfur (Li–S) batteries are developed for applications in next‐generation flexible electronics and electric vehicles with long cruising distances. Freestanding...
In this study, high‐purity and centimeter‐scale bulk Ta2Ni3Se8 crystals are obtained by controlling the growth temperature and stoichiometric ratio between tantalum, nickel, and selenium. It is demonstrated that the bulk Ta2Ni3Se8 crystals could be effectively exfoliated into a few chain‐scale nanowires through simple mechanical exfoliation and liquid‐phase exfoliation. Also, the calculation of electronic...
ABO3 perovskite materials and their derivatives have inherent structural flexibility due to the corner sharing network of the BO6 octahedron, and the large variety of possible structural distortions and strong coupling between lattice and charge/spin degrees of freedom have led to the emergence of intriguing properties, such as high‐temperature superconductivity, colossal magnetoresistance, and improper...
Nonfullerene organic solar cells (NFOSCs) are attracting increasing academic and industrial interest due to their potential uses for flexible and lightweight products using low‐cost roll‐to‐roll technology. In this work, two wide bandgap (WBG) polymers, namely P(fTh‐BDT)‐C6 and P(fTh‐2DBDT)‐C6, are designed and synthesized using benzodithiophene (BDT) derivatives. Good oxidation stability and high...
Penetrating electronics have been used for treating epilepsy, yet their therapeutic effects are debated largely due to the lack of a large‐scale, real‐time, and safe recording/stimulation. Here, the proposed technology integrates ultrathin epidural electronics into an electrocorticography array, therein simultaneously sampling brain signals in a large area for diagnostic purposes and delivering electrical...
In article number 1801732, Sungchil Yang, Jong‐Hyun Ahn, Sunggu Yang, and co‐workers present an approach of diagnostic and therapeutic epidural electronics. Ultrathin graphene electrodes are integrated into an electrocorticography (ECoG) array, therein simultaneously sampling brain signals in a large area for diagnostic purposes, and delivery of electrical pulses for treatment of epilepsy.
2D layered materials with sensitive surfaces are promising materials for use in chemical sensing devices, owing to their extremely large surface‐to‐volume ratios. However, most chemical sensors based on 2D materials are used in the form of laterally defined active channels, in which the active area is limited to the actual device dimensions. Therefore, a novel approach for fabricating self‐formed...
High‐quality and large‐area molybdenum disulfide (MoS2) thin film is highly desirable for applications in large‐area electronics. However, there remains a challenge in attaining MoS2 film of reasonable crystallinity due to the absence of appropriate choice and control of precursors, as well as choice of suitable growth substrates. Herein, a novel and facile route is reported for synthesizing few‐layered...
