Rechargeable aprotic lithium (Li)‐oxygen battery (LOB) is a potential next‐generation energy storage technology because of its high theoretical specific energy. However, the role of redox mediator on the oxide electrochemistry remains unclear. This is partly due to the intrinsic complexity of the battery chemistry and the lack of in‐depth studies of oxygen electrodes at the atomic level by reliable...
With the emergence of gene therapy utilizing viral vectors, the potential risks associated with these vectors have prompted increased attention toward non‐viral alternatives. DNA nanotechnology enables the assembly of specific oligonucleotide chains into nanostructures possessing defined spatial configurations. Due to their inherent characteristics, DNA nanostructures possess natural advantages as...
Quantum dots (QDs) are inorganic semiconductor nanocrystals capable of emitting light. The current major challenge lies in the use of heavy metals, which are known to be highly toxic to humans and pose significant environmental risks. Researchers have turned to indium (In) as a promising option for more environmentally benign QDs, specifically indium phosphide (InP). A significant obstacle remains...
Doxorubicin (DOX) is widely used as a chemotherapeutic agent for both hematologic and solid tumors and is a reasonable candidate for glioma treatment. However, its effectiveness is hindered by significant toxicity and drug resistance. Moreover, the presence of the blood–brain barrier (BBB) brings a crucial challenge to glioma therapy. In response, a GSH‐responsive and actively targeted nanoprodrug...
Fine‐tuning nanoscale structures, morphologies, and electronic states are crucial for creating efficient water‐splitting electrocatalysts. In this study, a method for electronic structure engineering to enhance overall water splitting in a corrosion‐resistant electrocatalyst matrix by integrating Pt, P dual‐doped Ni4Mo electrocatalysts onto a Ti4O7 nanorod grown on carbon cloth (Pt, P–Ni4Mo–Ti4O7/CC)...
“Perovskite / Carbon” interface has remained a key bottleneck for the hole‐conductor‐free perovskite solar cells based on carbon‐electrode (CPSCs), due to problems like loose physics contact, defects, energy mismatch, poor chemical coupling, etc. A previous study shows that octylammonium iodide (OAI) blending in carbon paste induced a kind of “in‐situ healing” effect for “perovskite / carbon” interface,...
Low‐cost and eco‐friendly Ni/NiO heterojunctions have been theoretically proven to be the ideal candidate for stepwise electrocatalysis of alkaline hydrogen evolution reaction, attributed to the preferred OHad adsorption by incompletely filled d orbitals of NiO phase and favorable Had adsorption energy of Ni phase. Nevertheless, most Ni/NiO compounds reported so far fail to exhibit excellent catalytic...
Some oxide‐based particulate photocatalyst sheets exhibit excellent activity during the water‐splitting reaction. The replacement of oxide photocatalysts with narrow‐bandgap photocatalysts based on nonoxides could provide the higher solar‐to‐hydrogen energy conversion efficiencies that are required for practical implementation. Unfortunately, the activity of nonoxide‐based photocatalyst sheets is...
Immunotherapy utilizing anti‐PD‐L1 blockade has achieved dramatic success in clinical breast cancer management but is often hampered by the limited immune response. Increasing evidence shows that immunogenic cell death (ICD) recently arises as a promising strategy for enlarging tumor immunogenicity and eliciting systemic anti‐tumor immunity effectively. However, developing simple but versatile, highly...
Violet phosphorus (VP) has attracted a lot of attention for its unique physicochemical properties and emerging potential in photoelectronic applications. Although VP has a van der Waals (vdW) structure similar to that of other 2D semiconductors, direct synthesis of VP on a substrate is still challenging. Moreover, optoelectronic devices composed of transfer‐free VP flakes have not been demonstrated...
The oxygen reduction reaction (ORR) catalyzed by transition‐metal single‐atom catalysts (SACs) is promising for practical applications in energy‐conversion devices, but great challenges still remain due to the sluggish kinetics of O═O cleavage. Herein, a kind of high‐density iron network‐like sites catalysts are constructed with optimized intermetallic distances on an amino‐functionalized carbon matrix...
As an innovative technology, four‐dimentional (4D) printing is built upon the principles of three‐dimentional (3D) printing with an additional dimension: time. While traditional 3D printing creates static objects, 4D printing generates “responsive 3D printed structures”, enabling them to transform or self‐assemble in response to external stimuli. Due to the dynamic nature, 4D printing has demonstrated...
Miniaturized flow cytometry has significant potential for portable applications, such as cell‐based diagnostics and the monitoring of therapeutic cell manufacturing, however, the performance of current techniques is often limited by the inability to resolve spectrally‐overlapping fluorescence labels. Here, the study presents a computational hyperspectral microflow cytometer (CHC) that enables accurate...
This work introduces a mixed‐transducer micro‐origami to achieve efficient vibration, controllable motion, and decoupled sensing. Existing micro‐origami systems tend to have only one type of transducer (actuator/sensor), which limits their versatility and functionality because any given transducer system has a narrow range of advantageous working conditions. However, it is possible to harness the...
Enzymatic activity depends on and can therefore be regulated by temperature. Selective modulation of the activity of different enzymes in one reaction pot would require temperature control local to each type of enzyme. It has been suggested previously that immobilization of enzyme on magnetic nanoparticles and exposing them to alternating magnetic field can enhance the reaction rate. This enhancement...
Due to the disadvantages of poor targeting, slow action, and low effectiveness of current commonly used cancer treatments, including surgery, chemotherapy, and radiotherapy, researchers have turned to DNA as a biomaterial for constructing drug delivery nanocarriers. DNA is favored for its biocompatibility and programmability. In order to overcome the limitations associated with traditional drug delivery...

Conventional rendering techniques are primarily designed and optimized for single‐frame rendering. In practical applications, such as scene editing and animation rendering, users frequently encounter scenes where only a small portion is modified between consecutive frames. In this paper, we develop a novel approach to incremental re‐rendering of scenes with dynamic objects, where only a small part...
