Summary: Using rational design, we developed a 17 kDa cyanobacteriochrome-based near-infrared (NIR-I) fluorescent protein, miRFP718nano, which efficiently binds endogenous biliverdin chromophore and emits bright fluorescence in mammalian cells and tissues. With a maximal emission at 718 nm and an emission tail in the short-wave infrared (SWIR) region, miRFP718nano enables deep-penetrating off-peak fluorescence imaging in vivo. We demonstrated the superiority of miRFP718nano-enabled SWIR imaging in various applications, including imaging of microbes in the mouse digestive tract, mammalian cells injected into the mouse mammary gland, and NF-kB activity in a mouse model of liver inflammation.

Summary: In this study, heterogeneous Ag2S-Au composite nanoparticles were successfully synthesized as effective catalysts for CO production through CO2RR. The nanocatalysts exhibited high CO Faradaic efficiency and stability. Density functional theory calculations revealed that the heterogeneous Ag2S-Au interface favored the generation of the COOH* intermediate for CO2RR, providing new application possibilities for noble metal-semiconductor nanocomposites.

Summary: Carbon-coated zinc telluride nanowires (ZnTe@C NWs) are designed as a high-performance cathode material for aqueous Zn batteries. The carbon-coated 1D nanostructure provides optimized transmission path for electrons and ions, maintains structure integrity upon volume variation and suppresses intermediates dissolution, resulting in improved cycling stability and reaction kinetics. A reversible six-electron reaction mechanism based on Te2-/Te4+ conversion is achieved, with excellent output capacity (586 mAh g(-1) at 0.1 A g(-1)) and lifespan (>250 mAh g(-1) retained for 400 cycles at 1 A g(-1)).

Summary: Wound healing is a complex biological process influenced by changes in the microenvironment, with cell polarity being a significant parameter. A method utilizing carbon dots to monitor cell polarity during wound healing has been successfully developed, with dynamic changes in polarity monitored for the first time in zebrafish. This study provides an important experimental basis for investigating wound healing using polarity-sensitive CDs.

Summary: The development of electrochemically active ultrafiltration membrane reactors has led to the synthesis of electrically conductive and flexible ultrafiltration membranes using drawable carbon nanotubes (CNT). These membranes show fine-tuned selectivity and high water permeance, as well as remarkable electrocatalytic properties for efficient water treatment. The results demonstrate the potential of CNT dry spinning technology for the scalable fabrication of highly permeable, selective membranes at an exceptional reaction rate.

Summary: We have designed matrix-free carbon dots with long wavelength and wavelength-tunable room-temperature phosphorescence (RTP) using microwave-assisted heating treatment. Three different RTP carbon dots were synthesized by using specific crosslink agents, acid catalyst, and carbonization-retardant matrix. After removing the matrix, the three matrix-free carbon dots exhibited RTP emission at 540, 550, and 570 nm under 365 nm excitation. The variations in RTP emission were attributed to particle size and band gap differences. Furthermore, these matrix-free carbon dots were successfully applied in information encryption and decryption.

Summary: In this study, we explore the use of quasi-aligned nano-array electrodes composed of SiC nanowire cores and sulfur-doped porous carbon shells (SiC@PC-S) as free-standing electrodes for Zn-ion hybrid supercapacitors. These electrodes exhibit an ultra-high areal capacitance of 38.24 mF/cm2 at a scan rate of 10 mV/s, with exceptional rate capability (-20.67 mF/cm2 even at 1000 mV/s). The constructed hybrid supercapacitors deliver a remarkable energy of 10.6 mu Wh/cm2, the highest among SiC-based supercapacitors ever reported. Furthermore, these hybrid devices demonstrate a high power density of 7.2 mW/cm2 and robust cycle stability with-97% capacitance retention after 5000 cycles at 2 mA/cm2, indicating promising practical applications.
