A Peptide Nucleic Acid‐Functionalized Heterojunction Thin Film Transistor as a Scalable and Reusable Platform for Label‐Free Detection of MicroRNA

open access: yesAdvanced Functional Materials, EarlyView.
A miniaturized, label‐free, and enzyme‐free biosensor (miR‐TFT) enables direct electrical detection of microRNA (miRNA) with single‐nucleotide specificity and a detection limit of 0.6 fM. Built on a tri‐channel In2O3/ZnO heterojunction and functionalized with bespoke peptide nucleic acid (PNA) probes, the device is robust, reusable, and compatible with

Drainage system of the upper unsaturated zone of a karst aquifer– a case study of the Hubelj spring catchment

open access: yesGeologija, 2004
A drainage system and a solute transport of a karst aquifer were studied by using an indirect research method basing on natural tracers. The research of mechanisms that cause the flow and solute transport from an aquifer upper unsaturated zone was ...

Label‐Free and Low‐Power Driven Cancer Biomarker Detection Enabled by 2D Hexagonal Titanium Oxide

open access: yesAdvanced Functional Materials, EarlyView.
A low‐power driven FET biosensor based on 2D hexagonal TiO2 detects the cancer biomarker carcinoembryonic antigen with high sensitivity, a low detection limit of 0.22 pg mL−1, and excellent selectivity. Leveraging the unique electronic properties of the material, this work demonstrates strong potential for integration into miniature and portable cancer

Numerical Three-Dimensional Model of Airport Terminal Drainage System

open access: yesStudia Geotechnica et Mechanica, 2014
During the construction of an airport terminal it was found that as a result of the hydrostatic pressure of underground water the foundation plate of the building had dangerously shifted in the direction opposite to that of the gravitational forces.

Epitaxial Interface‐Driven Photoresponse Enhancement in Monolayer WS2–MoS2 Lateral Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Surface potential distribution image, along with the derived electric field distribution across the interface, reveals that the electric field reaches its peak at the interface. Additionally, the spectral response of the heterointerface exhibits higher and broader features compared to its bare counterparts.

Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

open access: yesAdvanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...
