There is a rising interest in employing the negative capacitance (NC) effect to achieve sub-60 mV/decade (below thermal limit) switching field-effect transistors (FETs). The NC effect, which an effectual amplification of applied gate potential, realized by incorporating ferroelectric material series with dielectric stack FET. One leading challenges such NC-FETs variable substrate exhibited 3D semiconductor channels (bulk, Fin, or nanowire) that minimizes extent switching. In this work, we...
Atomically thin two-dimensional (2D) materials are promising candidates for sub-10 nm transistor channels due to their ultrathin body thickness, which results in strong electrostatic gate control. Properly scaling a technology requires reducing both the channel length (distance from source drain) and contact that drain interface with semiconducting channel). Contact remains an unresolved epidemic scaling, affecting devices all semiconductors-silicon 2D materials. Here, we show clean edge...
Urinary tract infections are predominantly caused by uropathogenic Escherichia coli (UPEC). UPEC infects bladder epithelial cells (BECs) via fusiform vesicles, escapes into the cytosol to evade exocytosis, and establishes intracellular bacterial communities (IBCs) for next round of infection. The vesicle escape mechanism remains unclear. Here we show that senses host immune responses initiates upregulating a key phospholipase. phospholipase PldA disrupts membrane, pldA expression is...
Abstract Prime editing is a versatile gene tool that enables precise sequence changes of all types in the genome, but its application rather limited by efficiency. Here, we first apply Suntag system to recruit transcription factor P65 and enhance desired outcomes prime system. Next, MS2 hairpins are used MS2-fused confirmed recruitment protein could effectively improve efficiency both PE3 PE5 systems. Moreover, this suggests increased most likely associated with induction chromatin...

Thousands of reports have demonstrated the exceptional performance sensors based on carbon nanotube (CNT) transistors, with promises transformative impact. Yet, effect long-term bias stress individual CNTs, critical for most sensing applications, has remained uncertain. Here, we report ranges under which CNT transistors can operate continuously months or more without degradation. Using a custom characterization system, impacts defect formation and charge traps stability CNT-based extended...
Two-dimensional (2D) van der Waals materials are subject to mechanical deformation and thus forming bubbles wrinkles during exfoliation transfer. A lack of interfacial "flatness" has implications for interface properties, such as those formed by metal contacts or insulating layers. Therefore, an understanding the detailed properties 2D interfaces, especially their flatness under different conditions, is high importance. Here we use cross-sectional scanning transmission electron microscopy...

Two-dimensional (2D) materials offer exciting possibilities for numerous applications, including next-generation sensors and field-effect transistors (FETs). With their atomically thin form factor, it is evident that molecular activity at the interfaces of 2D can shape electronic properties.
