P‐type Sb2Te3 has been recognized as a potential thermoelectric material for applications in low‐medium temperature ranges. However, its inherent high carrier concentration and lattice thermal conductivity led to a relatively low ZT value, particularly around room temperature. This study addresses these limitations by leveraging high‐energy ball milling and rapid hot‐pressing techniques to substantially...
This work reports a covalent organic framework composite structure (PMDA‐NiPc‐G), incorporating multiple‐active carbonyls and graphene on the basis of the combination of phthalocyanine (NiPc(NH2)4) containing a large π‐conjugated system and pyromellitic dianhydride (PMDA) as the anode of lithium‐ion batteries. Meanwhile, graphene is used as a dispersion medium to reduce the accumulation of bulk covalent...
The recently developed defective 19‐electron half‐Heusler (HH) compounds, represented by Nb1−δCoSb, possess massive intrinsic vacancies at the cation site and thus intrinsically low lattice thermal conductivity that is desirable for thermoelectric (TE) applications. Yet the TE performance of defective HHs with a maximum figure of merit (zT) <1.0 is still inferior to that of the conventional 18‐electron...
In China, iron (Fe) availability is low in most soils but cadmium (Cd) generally exceeds regulatory soil pollution limits. Thus, biofortification of Fe along with mitigation of Cd in edible plant parts is important for human nutrition and health. Carbon dots (CDs) are considered as potential nanomaterials for agricultural applications. Here, Salvia miltiorrhiza‐derived CDs are an efficient modulator...
1D carbon nanotubes have been widely applied in many fields, such as catalysis, sensing and energy storage. However, the long tunnel‐like pores and relatively low specific surface area of carbon nanotubes often restrict their performance in certain applications. Herein, a dual‐silica template‐mediated method to prepare nitrogen‐doped mesoporous carbon nanotubes (NMCTs) through co‐depositing polydopamine...
Liquid hydrogen carriers featuring high hydrogen content, safety, and hydrogen release on demand have motivated great endeavors for sustainable hydrogen supply. Nonetheless, direct hydrogen release is limited by the ultralow hydrogen evolution rate, while the conventional manner of extra additive and solvent addition for promoting rates greatly deteriorates its hydrogen storage density. Thus, it is...
Developing efficient and robust non‐precious‐metal‐based catalysts to accelerate electrocatalytic reaction kinetics is crucial for electrochemical water‐urea splitting. Herein, Fe‐doped NiS–NiS2 heterostructured microspheres, an electrocatalyst, are synthesized via etching Prussian blue analogues following a controlled annealing treatment. The resulting microspheres are constructed by mesoporous nanoplates,...
Wearable thermoelectric generators have great potential to be utilized as the power supply for wearable electronics. However, the limited temperature difference across the thermoelectric generators significantly degrades the output performance, which is anticipated to be improved by enhancing the thermal radiation at the cold side without extra energy consumption. In this paper, the impact of thermal...
Solid phase conversion sulfur cathode is an effective strategy for eliminating soluble polysulfide intermediates (LiPSs) and improving cyclability of Li‐S batteries. However, realizing such a sulfur cathode with high sulfur loading and high capacity utilization is very challenging due to the insulating nature of sulfur. In this work, a strategy is proposed for fabricating solid phase conversion sulfur...
The development of high‐efficiency, robust, and available electrode materials for oxygen evolution reaction (OER) and lithium‐ion batteries (LIBs) is critical for clean and sustainable energy system but remains challenging. Herein, a unique yolk–shell structure of Fe2O3 nanotube@hollow Co9S8 nanocage@C is rationally prepared. In a prearranged sequence, the fabrication of Fe2O3 nanotubes is followed...
For the proliferation of the supercapacitor technology, it is essential to attain superior areal and volumetric performance. Nevertheless, maintaining stable areal/volumetric capacitance and rate capability, especially for thick electrodes, remains a fundamental challenge. Here, for the first time, a rationally designed porous monolithic electrode is reported with high thickness of 800 µm (46.74 mg...
Significantly enhanced thermoelectric performance is achieved for eco‐friendly SnTe by a coorperative effect between a dopant resonant energy level and interstitial defects. By manipulating the band structure through indium doping, the Seebeck coefficient is remarkably improved, leading to an enhanced power factor, with a high level of ≈29 µW cm−1 K−2 at 873 K. Lattice thermal conductivity is sharply...
Pancreatic cancer is a highly aggressive malignancy that strongly resists extant treatments. The failure of existing therapies is majorly attributed to the tough tumor microenvironment (TME) limiting drug access and the undruggable targets of tumor cells. The formation of suppressive TME is regulated by transforming growth factor beta (TGF‐β) signaling, while the poor response and short survival of...
Solution‐processable small molecules (SMs) have attracted intense attention due to their definite molecular structures, less batch‐to‐batch variation, and easier structure control. Herein, two new SM donors based on substituted isatin unit (DI3T, DI3T‐2F) are synthesized and applied as electron donors with the mixture of PC71BM to construct organic photovoltaics. As a result, 5,6‐difluoro isatin derivative...
Hydrogen evolution reaction (HER) has prospect to becoming clean and renewable technology for hydrogen production and Ni–Mo alloy is among the best HER catalysts in alkaline electrolytes. Here, an in situ topotactic reduction method to synthesize ultrathin 2D Ni–Mo alloy nanosheets for electrocatalytic hydrogen evolution is reported. Due to its ultrathin structure and tailored composition, the as‐synthesized...
The diverse biological effects of nanomaterials form the basis for their applications in biomedicine but also cause safety issues. Induction of autophagy is a cellular response after nanoparticles exposure. It may be beneficial in some circumstances, yet autophagy‐mediated toxicity raises an alarming concern. Previously, it has been reported that upconversion nanoparticles (UCNs) elicit liver damage,...
Antibody–drug conjugate (ADC) targeting antigens expressed on the surface of tumor cells are an effective approach for delivering drugs into the cells via antigen‐mediated endocytosis. One of the well‐known tumor antigens, the CD20 of B‐lymphocyte, has long been suggested to be noninternalizing epitope, and is thus not considered a desirable target for ADCs. Here, sortase A (srtA)‐mediated transpeptidation...
Many nanomaterials are reported to disrupt lysosomal function and homeostasis, but how cells sense and then respond to nanomaterial‐elicited lysosome stress is poorly understood. Nucleus translocation of transcription factor EB (TFEB) plays critical roles in lysosome biogenesis following lysosome stress induced by starvation. The authors previously reported massive cellular vacuolization, along with...
