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,...

In article number 2202694, Dong‐Hyun Kim and co‐workers develop reactive oxygen species (ROS)–responsive biodegradable metallic nanoparticles that can be used for various biomedical applications. Given the challenges of non‐biodegradability of potent inorganic nanoparticles, the introduction of a ROS‐responsive cleavable hierarchical metallic supra‐nanostructure provides an exciting...
A reactive oxygen species (ROS) responsive cleavable hierarchical metallic supra‐nanostructure (HMSN) is reported. HMSN structured with thin branches composed of primary gold (Au) nanocrystals and silver (Ag) nano‐linkers is synthesized by a one‐pot aqueous synthesis with a selected ratio of Au/Ag/cholate. ROS responsive degradability of HMSN is tested in the presence of endogenous and exogeneous...
Next‐generation energy storage devices such as lithium–sulfur batteries (LSBs) face several challenges including fast charging and high‐power delivery. Thus, it is necessary to improve the stability of the electrodes with efficient electrochemical system. In this work, a durable sulfur cathode even at high rates is enabled via lean binder content. The binder consists of a chitosan cross‐linked with...
Ferumoxytol capped anti PD‐L1 antibodies (aPD‐L1) loaded ultra‐large pore mesoporous silica nanoparticles (Fer‐ICB‐UPMSNPs) are delivered with image guidance after cabazitaxel (Cbz) chemotherapy for the treatment of prostate cancer. Sustained release of ICB from UPMSNP inhibits the immunosuppressive tumor microenvironment and activates tumor specific dendritic cells (DC). Activated antigen presenting...
Herein, ferumoxytol (Fer) capped antiprogrammed cell death‐ligand 1 (PD‐L1) antibodies (aPD‐L1) loaded ultralarge pore mesoporous silica nanoparticles (Fer‐ICB‐UPMSNPs) are formulated for a sequential magnetic resonance (MR) image guided local immunotherapy after cabazitaxel (Cbz) chemotherapy for the treatment of prostate cancer (PC). The highly porous framework of UPMSNP provides a large capacity...
Branched gold nanoparticle (BGNP)‐coated Clostridium novyi‐NT (C. novyi‐NT) spores are developed for computed tomography (CT)‐guided bacteriolytic tumor therapy. The BGNP‐coated spores are successfully injected into a tumor site under CT image guidance. As a result, a strong antitumor effect is observed in a PC3 prostate tumor‐bearing mouse model.
Anaerobic Clostridium novyi‐NT (C. novyi‐NT) has proved to be effective for treating tumors. X‐ray computed tomography (CT) image guided delivery of this strain of bacteria to tumors has several great advantages over previous methods. In article number 1602722, A. C. Larson, D.‐H. Kim, and co‐workers developed an approach to coat the surface of C. novyi‐NT spores with gold nanoparticles for CT‐guided...
