A Zn anode can offset the low energy density of a flow battery for a balanced approach toward electricity storage. Yet, when targeting inexpensive, long‐duration storage, the battery demands a thick Zn deposit in a porous framework, whose heterogeneity triggers frequent dendrite formation and jeopardizes the stability of the battery. Here, Cu foam is transferred into a hierarchical nanoporous electrode...
Low responsiveness to anti‐programmed death‐1/programmed death‐ligand 1 (anti‐PD‐1/PD‐L1) for solid tumors indicates the presence of other immunosuppressive pathways. Siglec15, a newly discovered immune checkpoint, has been reported to repress immune responses in the tumor microenvironment (TME) and regulate osteoclast differentiation. However, the role of Siglec15 in the treatment for bone metastasis...
Polar domain walls in centrosymmetric ferroelastics induce inhomogeneity that is the origin of advantageous multifunctionality. In particular, polar domain walls promote charge‐carrier separation and hence are promising for energy conversion applications that overcome the hurdles of the rate‐limiting step in the traditional photoelectrochemical water splitting processes. Yet, while macroscopic studies...
The poor chemical miscibility between metal and organic materials usually leads to both structural and energetic mismatches at gold/organic interfaces, and thereby, high contact resistance of organic electronic devices. This study shows that the contact resistance of organic field‐effect transistors is significantly reduced by one order of magnitude, by reforming the contact interface between gold...
For expanding the applications of 2D transition metal dichalcogenides (TMDCs), integrating functional devices with diverse conduction polarities in the same parent material is a very promising direction. Improving the contact issue at the metal‐semiconductor interface also holds fundamental significance. To achieve these concurrently, step‐like Cr2S3 vertical stacks with varied thicknesses are achieved...
In article number 1906435, Qing Chen and co‐workers obtain high‐index {01} facets of ZnO during wet chemical etching of the (000) O‐terminated surface of ZnO and also provide the direct experimental evidence of the micromasking mechanism for the hillocks formation via an in situ liquid cell transmission electron microscopy study.
Special surface plays a crucial role in nature as well as in industry. Here, the surface morphology evolution of ZnO during wet etching is studied by in situ liquid cell transmission electron microscopy and ex situ wet chemical etching. Many hillocks are observed on the (000) O‐terminated surface of ZnO nano/micro belts during in situ etching. Nanoparticles on the apex of the hillocks are observed...
Glucose oxidase (GOx) can react with intracellular glucose and oxygen (O2) to produce hydrogen peroxide (H2O2) and gluconic acid, which can cut off the nutrition source of cancer cells and consequently inhibit their proliferation. Therefore, GOx is recognised as an ideal endogenous oxido‐reductase for cancer starvation therapy. This process can further regulate the tumor microenvironment by increasing...
An overview of the numerous latest research in microfiber humidity sensors is carried out with a specific focus on measurement methods, humidity sensitive materials, probe structures, and sensing properties of different sensors. First, five mainstream measurement structures, including taper, fiber grating, coupler, resonator, and interferometer are reviewed. It is concluded that these measurement...
