Novel 2D materials with low‐symmetry structures exhibit great potential applications in developing monolithic polarization‐sensitive photodetectors with small volume. However, owing to the fact that at least half of them presented a small anisotropic factor of ≈2, comprehensive performance of present polarization‐sensitive photodetectors based on 2D materials is still lower than the practical application...
Noble metallic aerogels with the self‐supported hierarchical structure and remarkable activity are promising for methanol fuel cells, but are limited by the severe poisoning and degradation of active sites during electrocatalysis. Herein, the highly stable electrocatalyst of N‐doped carbon dots‐PtNi (NCDs‐PtNi) aerogels is proposed by confining NCDs with alloyed PtNi for methanol oxidation and oxygen...
Quasi‐solid state thermocells hold immense potential for harnessing untapped low‐grade heat and converting it into electricity via the thermogalvanic effect. However, integrated N‐type thermocells face limitations in thermoelectric performance due to the rare N‐type systems and the poor electroactivity of the electrode interfaces. Herein, a low‐cost, high‐power N‐type quasi‐solid state thermocell...
Persistent luminescence (PersL) materials exhibit thermal‐favored optical behavior, enabling their unique applications in security night vision signage, in vivo bioimaging, and optical anti‐counterfeiting. Therefore, developing efficient and color‐tunable PersL materials is significantly crucial in promoting advanced practical use. In this study, hexagonal Zr4+‐doped CsCdCl3 perovskite is synthesized...
Targeted Multimodal Cancer Therapies
The immunogenic cell‐based microrobots capable of multimodal cancer therapy are constructed by loading bioengineered bacterial outer membrane vesicles (OMVs) and magnetic nanoparticles with macrophages. Such active medical platform integrates steerable magnetic propulsion, antitumor immune regulation and anticancer peptides of OMVs, and tumor targeting and inhibition...
Motile microrobots open a new realm for disease treatment. However, the concerns of possible immune elimination, targeted capability and limited therapeutic avenue of microrobots constrain its practical biomedical applications. Herein, a biogenic macrophage‐based microrobot loaded with magnetic nanoparticles and bioengineered bacterial outer membrane vesicles (OMVs), capable of magnetic propulsion,...
In recent decades, the growing demands for energy saving and accompanying heat mitigation concerns, together with the vital goal for carbon neutrality, have drawn human attention to the zero‐energy‐consumption cooling technique. Recent breakthroughs in passive daytime radiative cooling (PDRC) might be a potent approach to combat the energy crisis and environmental challenges by directly dissipating...
Next‐generation imaging systems require photodetectors with high sensitivity, polarization sensitivity, miniaturization, and integration. By virtue of their intriguing attributes, emerging 2D materials offer innovative avenues to meet these requirements. However, the current performance of 2D photodetectors is still below the requirements for practical application owing to the severe interfacial recombination,...
Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is a common respiratory critical syndrome that currently has no effective therapeutic interventions. Pulmonary macrophages play a principal role in the initiation and progression of the overwhelming inflammation in ALI/ARDS. Here, a type of fluorous‐tagged bioactive peptide nanoparticle termed CFF13F is developed, which can be efficiently...
Polarization‐sensitive photodetectors based on van der Waals heterojunctions (vdWH) have excellent polarization‐resolved optoelectronic properties that can enable the applications in polarized light identification and imaging. With the development of optical microcomputer control systems (OMCS), it is crucial and energy efficient to adopt the self‐powered and polarization‐resolved signal‐generators...
The advantage of using flexible metallic structures as the substrate of flexible lasers over plastic materials is its strong mechanical strength and high thermal conductivity. Here, it is proposed to deposit CsPbBr3 perovskite quantum dots onto Ni porous foam for the realization of flexible lasers. Under two‐photon 800 nm excitation at room temperature, incoherent random lasing emission is observed...
Understanding the conformation effect on molecular packing, miscibility, and photovoltaic performance is important to open a new avenue for small‐molecule acceptor (SMA) design. Herein, two novel acceptor–(donor‐acceptor1‐donor)–acceptor (A‐DA1D‐A)‐type asymmetric SMAs are developed, namely C‐shaped BDTP‐4F and S‐shaped BTDTP‐4F. The BDTP‐4F‐based polymer solar cells (PSCs) with PM6 as donor, yields...
Efficient organic solar cells (OSCs) are fabricated using polymer PM6 as donor, and IPTBO‐4Cl and MF1 as acceptors. The power conversion efficiency (PCE) of IPTBO‐4Cl based and MF1 based binary OSCs individually arrive to 14.94% and 12.07%, exhibiting markedly different short circuit current density (JSC) of 23.18 mA cm−2 versus 17.01 mA cm−2, fill factor (FF) of 72.17% versus 78.18% and similar open...
Silicon‐based electronic devices, especially graphene/Si photodetectors (Gr/Si PDs), have triggered tremendous attention due to their simple structure and flexible integration of the Schottky junction. However, due to the relatively poor light–matter interaction and mobility of silicon, these Gr/Si PDs typically suffer an inevitable compromise between photoresponsivity and response speed. Herein,...
Efficient ternary organic solar cells (OSCs) are fabricated by employing a polymer PBT1‐C as the donor and two non‐fullerene materials, MeIC and MeIC2, as one alloyed acceptor. The optimized ternary OSCs with 30 wt% MeIC2 in acceptors achieve a power conversion efficiency (PCE) of 12.55%, which is much higher than that of 11.47% for MeIC‐based binary OSCs and 11.41% for MeIC2‐based binary OSCs. The...
T. Si, Q. He, and co‐workers demonstrate the fuel‐free, highly efficient propulsion of gold nanoshell‐functionalized polymeric multilayer rockets under NIR illumination. On page 577, the NIR‐driven rockets, fabricated by nanoporous template‐assisted polyelectrolyte layer‐by‐layer assembly, can move at a speed of 160 μm s−1 owing to the self‐thermophoretic forces generated by the photothermal effect...
A gold nanoshell‐functionalized polymer multilayer nanorocket performs self‐propulsion upon the irradiation with NIR light in the absence of chemical fuel. Theoretical simulations reveal that the NIR light‐triggered self‐thermophoresis drives the propulsion of the nanorocket. The nanorocket also displays efficient NIR light‐triggered propulsion in biofluids and thus holds considerable promise for...
