Hybrid supercapacitors (HSCs), also called supercapattery, which can substitute for low power density batteries have attracted extensive interest. However, when HSCs comes to commercial applications, there is still space for improvement in energy density. It seems that designing of electrode with high capacity is an effective measure. Herein, amorphous–crystalline MoO3‐Ni3S2/NF‐0.5 nanosheet arrays...
Cisplatin is a first‐line drug in clinical cancer treatment but its efficacy is often hindered by chemoresistance in cancer cells. Reduced intracellular drug accumulation is revealed to be a major mechanism of cisplatin resistance. Nanoscale drug delivery systems could help to overcome this problem because of their more active cellular uptake and more accurate tumor localization. DNA nanostructures...
Materials exhibiting persistent luminescence (PersL) have great prospect in optoelectronic and biomedical applications such as optical information storage, bio‐imaging, and so on. Unfortunately, PersL materials with multimode emission properties have been rarely reported, although they are expected to be very desirable in multilevel anti‐counterfeiting and encryption applications. Herein, Cr3+‐doped...
Exosomes are secreted by most cell types and circulate in body fluids. Recent studies have revealed that exosomes play a significant role in intercellular communication and are closely associated with the pathogenesis of disease. Therefore, exosomes are considered promising biomarkers for disease diagnosis. However, exosomes are always mixed with other components of body fluids. Consequently, separation...
The atomic structure of free‐standing graphene comprises flat hexagonal rings with a 2.5 Å period, which is conventionally considered the only atomic period and determines the unique properties of graphene. Here, an unexpected highly ordered orthorhombic structure of graphene is directly observed with a lattice constant of ≈5 Å, spontaneously formed on various substrates. First‐principles computations...
In article number 1902637, Guosheng Shi, Yi Zhang, and co‐workers discover an orthorhombic crystal of graphene with an ≈5 Å period formed on various substrates, which can be applied to control the epitaxial self‐assembly of amyloid peptides. First‐principle computations show that this atomic structure can be attributed to dipoles between the graphene surface and substrates.
Structural deoxyribonucleic acid (DNA) nanotechnology offers a robust platform for diverse nanoscale shapes that can be used in various applications. Among a wide variety of DNA assembly strategies, DNA origami is the most robust one in constructing custom nanoshapes and exquisite patterns. In this account, the static structural and functional patterns assembled on DNA origami are reviewed, as well...
In article number 1901397, Yu Shrike Zhang, Ai‐Zheng Chen, and co‐workers fabricate highly open porous microspheres (HOPMs) using a microfluidic technique for harboring skeletal myoblasts towards cell delivery applications in situ. The structure of the HOPMs conveniently provides a favorable microenvironment for cell adhesion and proliferation, improved cell retention and vascularization, as well...
Microscale cell carriers have recently garnered enormous interest in repairing tissue defects by avoiding substantial open surgeries using implants for tissue regeneration. In this study, the highly open porous microspheres (HOPMs) are fabricated using a microfluidic technique for harboring proliferating skeletal myoblasts and evaluating their feasibility toward cell delivery application in situ....
