Summary: It has been found that graphene oxide (GO) undergoes transformation from micro to nanoscale and forms nanoscale GO (nanoGO) when subjected to adsorbed particular organic molecules. A new model is proposed to take nanosizing into account, and DFT calculations explain the selective adsorption behavior of different adsorbates on GO. The GO-nanoGO transformation is supported by marked changes in the surface area of GO during liquid phase adsorption of organic molecules.

Summary: A novel graphene oxide-supported TixAl1-xOy bimetallic oxide was successfully synthesized for uranium removal. The addition of graphene oxide improved the dispersion of TixAl1-xOy nanoparticles and increased the active sites of the complexes. The adsorption efficiency and capacity of GO@TixAl1-xOy for uranium significantly outperformed other bimetallic oxides, reaching 97.8% and 614.6 mg g-1 at T = 298 K and pH = 4. The adsorption process followed the pseudo-second-order and Langmuir models, indicating a uniform chemisorption mechanism. The excellent adsorption performance was attributed to strong complexation, oxygen vacancy filling, and reduction.

Summary: The surface porosity of graphene-based aerogels plays a crucial role in applications involving mass transfer. Through experiments and simulations, it is found that high shear stress during the fabrication process leads to a non-porous surface, while crosslinking of the sheets results in a porous surface. Controlling the surface porosity of printed graphene-oxide aerogels (GOA) can be achieved by regulating the crosslinking agents and shear stress. The study demonstrates the performance advantages of GOA with porous surface in dye adsorption, highlighting the importance of surface porosity in specific applications.

Summary: In order to increase the specific capacitance of supercapacitors, polyaniline (PANI) has been used as an additive electrode material. In this study, a molecular-level uniform reduced graphene oxide/PANI (rGO/PANI) composite film was synthesized through self-assembly and specific thermal reduction, which showed great potential in flexible supercapacitors with high areal capacitance. The performance of the rGO/PANI film, such as specific areal capacitance and cycling stability, was significantly enhanced compared to the pure rGO electrode.

Summary: This study introduces a novel Type II heterojunction consisting of BiVO4 thin film and diamond-like carbon (DLC) to the PEC system, which significantly enhances the PEC water-splitting activity. Compared to the pure BiVO4, the BiVO4/DLC heterojunction exhibits increased photocurrent density and improved stability. The enhancement in PEC performance is attributed to the Type II heterojunction photoanodes that promote carrier mobility and reduce the recombination rate of electron-hole pairs. Furthermore, the sp2 carbon phase in DLC acts as a conductive channel, while the sp3 carbon phase provides stable support and passivation effect, leading to an enhancement in both PEC water splitting performance and long-time stability.

Summary: Prostate cancer is a lethal cause of cancer-related death in males, characterized by genomic instability and disrupted signaling transduction. This study used CRISPR system to screen E3 ubiquitin ligases in PCa cells and found RNF19A as a novel oncodriver. RNF19A was frequently amplified and highly expressed in PCa, correlated with advanced Gleason Score and predicted castration resistance. Mechanistically, RNF19A ubiquitylated TRIP13 and was transcriptionally activated by AR and HIF1A. Targeting AR/HIF1A-RNF19A-TRIP13 signaling could be an alternative option for PCa diagnosis and therapy.

Summary: A 2D bimetallic phthalocyanine-based COF (COF-CuNiPc) was reported as a chemiresistive gas sensor with high gas-sensing performance for nitrogen dioxide (NO2). COF-CuNiPc with an asymmetric synergistic effect achieved a fast adsorption/desorption process to NO2. The bimetallic structure of COF-CuNiPc provided a proper band gap and the CuNiPc heterometallic active site accelerated the adsorption/desorption processes. The concept of a synergistic effect enabled by bimetallic phthalocyanines in this work can provide an innovative direction for designing high-performance chemiresistive gas sensors.

Summary: All-carbon nano-heterostructure photodetectors based on different carbon allotropes exhibit excellent photoelectric performance. However, the performance is limited by the interfacial charge transfer and large dark current of graphene. In this study, asymmetric all-carbon nano-heterostructures with C-60/graphene/single-walled carbon nanotube (SWCNT) heterojunctions were designed and demonstrated to have excellent photoelectric response in the visible to NIR range, high responsivity, ultrahigh detectivity, and fast response time. The interfacial charge transfer mechanism was also investigated. This work provides insights into interfacial charge transfer in carbon-based heterostructures and offers a strategy for designing and fabricating high-performance all-carbon nano-heterostructure photodetectors.

Summary: The interfacial charge transfer between single-walled carbon nanotubes (SWCNTs) and graphene is systematically investigated under different external conditions, including bias voltage, temperature, and atmosphere. It is found that electrons are transferred from SWCNTs to graphene when the applied voltage deviates from the neutral point voltage of -4 V. The built-in electric field induces the transfer of electrons from SWCNTs to graphene under various atmospheric and temperature conditions. This study provides important insights into the interfacial charge transfer between SWCNTs and graphene and offers guidance for designing high-performance all-carbon vdW heterostructure nanodevices.
