The conventional reconfiguration of transistors requires an additional independent terminal for controllable gate input, which complicates the device structure and makes circuit integration difficult. In this work, we propose a reconfigurable diode based on a 2D layered copper indium thiophosphate (CIPS) and graphene (Gr) van der Waals lateral heterojunction, exhibiting distinctively bias-dependent reconfiguration. The reconfiguration characteristics include reversible memristive behaviors with a current on/off ratio of about 10 and switchable rectifying polarity with a rectifying ratio of up to 3 × 10.

Article Synopsis
  • - Small extracellular vesicles (sEVs) play a crucial role in communicating signals within the hypoxic tumor microenvironment, affecting cancer progression, but the details of how hypoxia influences their production are not well understood.
  • - In head and neck squamous cell carcinoma (HNSCC) cells under low oxygen levels, researchers observed increased sEV secretion and changes in their cargo, along with an upregulation of HRS, a key protein involved in vesicle transport.
  • - HRS, activated by hypoxia inducible factor-1α (HIF-1α), helps reduce degradation of multivesicular bodies, thus altering the packaging of certain proteins into sEVs that promote tumor growth and influence surrounding macroph

The development of negative photoconductivity (NPC)-related devices is of great significance for numerous applications, such as optoelectronic detection, neuromorphic computing, and optoelectronic synapses. Here, an unusual but interesting NPC phenomenon in the novel cesium cobalt chlorine (CsCoCl) single crystal-based optoelectronic devices is reported, which simultaneously possess volatile resistive switching (RS) memory behavior. Joint experiment-theory characterizations reveal that the NPC behavior is derived from the intrinsic vacancy defects of CsCoCl, which could trap photogenerated charge carriers and produce an internal electric field opposite to the applied electric field.

  • - The fabrication of halide perovskite (HP) solar cells typically faces challenges due to incompatibility between material layers, but a new method called lamination allows for separate processing of half-stacks that are bonded together to create the final device.
  • - This study focuses on how different lamination conditions (temperature, pressure, and time) affect important properties like bonding quality, grain size, and light emission in the solar cells.
  • - The research finds that a lamination temperature of 150 °C is optimal, leading to over 95% bonding success and improved grain size and light emission, ultimately impacting the performance of the solar cells.

  • The overuse of antibiotics is leading to bacterial resistance, posing serious risks to human health and ecosystems.
  • Recent studies suggest that black phosphorus (BP), a two-dimensional nanomaterial, may have antibacterial properties but also impacts the spread of antibiotic resistance genes (ARGs).
  • Findings indicate that low concentrations of 2D-BP actually promote the transfer of ARGs between bacteria through oxidative stress and changes in bacterial membrane permeability, while high concentrations reduce this transfer.

The structure of zwitterion has great impact on the separation properties of zwitterionic hydrophilic stationary phases. To better understand the role of anionic groups of zwitterions, a novel carboxybetaine-based zwitterionic monolithic column was first prepared through thermo-initiated copolymerization of functional monomer (3-acrylamidopropyl)-dimethyl-(2-carboxymethyl) ammonium (CBAA) and crosslinker ethylene dimethacrylate (EDMA) within 100 μm ID capillary. The optimal poly(CBAA-co-EDMA) monolithic column exhibited satisfactory mechanical and chemical stability, good repeatability, high column efficiency (96,000 plates/m), and excellent separation performance for different classes of polar compounds (i.

The somatic embryo (SE) has bipolar characteristics, which is an ideal material for large-scale microproduction of woody plants represented by apples, and the somatic embryo is also an excellent receptor for genetic transformation. The formation of embryogenic cells is a prerequisite for somatic embryogenesis to occur. The embryogenic cells of apples cannot be obtained without induction of exogenous auxin, but how the auxin pathway regulates this process remains unknown.

The emergence of covalent adaptable networks (CANs) based on dynamic covalent bonds (DCBs) presents a promising avenue for achieving resource recovery and utilization. In this study, we discovered a dynamic covalent bond called selenacetal, which is obtained through a double click reaction between selenol and activated alkynes. Density functional theory (DFT) calculations demonstrated that the ΔG for the formation of selenoacetals ranges from 12 to 18 kJ mol, suggesting its potential for dynamic reversibility.
