Three-dimensional (3D) bulk fin-typed field effect transistors (FinFETs) have emerged as key devices that can scale down the technology node beyond 22-nm. However, the scaled devices have created new sources of fluctuation inherent in 3D geometry. The interface trap is one such fluctuation that is caused by the trapping and de-trapping of charge carriers and has an adverse effect on device characteristics and variability. In this work, we study impacts of random interface traps (RITs) on electrical characteristic of bulk FinFETs by using a 3D quantum-mechanically corrected device simulation. RIT position effects on short channel effects (SCEs) are examined with physical governed influence to show the major fluctuations. More than 50% reductions of the RITs-induced characteristic fluctuation of the germanium (Ge) devices are observed, compared with Si devices. The Ge ones can reduce SCE variations and exhibit high immunity to RITs.

Label-free reflectometry sensors detect proteins by measuring the reflectance properties of a thin film on a substrate. As light encounters a thin film layer stack, reflections from the layer boundaries interfere with each other encoding information about layer properties onto the reflected light. Existing reflectometric techniques measure changes in thin film thickness by observing a change in the interference spectrum, polarization state or reflectance relative to an initial antireflective condition at fixed angle and wavelength. These techniques are used for biosensing by detecting changes in film thickness as analyte binds to surface-bound ligand. Existing approaches are limited by low multiplexing capability, limited sensitivity, or by requiring high manufacturing tolerances of the detector substrates. Lambda Theta Reflectometry (LTR) is a novel reflectometric technique that measures changes in film thickness by measuring the location of null reflectivity as a function of wavelength (lambda) and angle of incidence (theta). The substrate is simultaneously illuminated with a range of angles and wavelengths and reflected light is angularly and spectrally resolved. The optical thickness of the thin film is retrieved by fitting the location of the null in lambda theta space. A prototype LTR reflectometer has demonstrated the ability to measure SiO2 layer thickness with milli-Ångstrom precision. LTR measurements of SiO2/Si oxide films are in excellent agreement with spectroscopic ellipsometry for films thickness ranging from 1390-1465 Å. LTR enables sensitive measurements across a range of analyte concentrations without requiring stringent control over initial layer stack thickness. © 2025 SPIE.

A paper-based biosensor integrating a functionalized porous silicon (PSi) membrane as the active sensing element for quantifiable protein detection has been developed. For similar short-time exposures to an analyte, improved molecular transport in PSi membranes when on paper leads to larger signal changes compared to traditional PSi films that remain on a silicon substrate. In this work, we discuss controlling the incubation time of the analyte and the overall testing time of the sensor by incorporating different combinations of wicking and absorbent paper beneath the PSi membrane. With this control, the PSi-on-paper sensor platform has the potential to serve as an effective low-cost rapid diagnostic test with highly sensitive, quantitative readout for a wide range of analytes. © 2025 SPIE.

A new approach to treating vascular blockages has been developed to overcome the limitations of current thrombolytic therapies. This approach involves biosafety and multimodal plasma-derived theranostic platelet vesicle incorporating iron oxide constructed nano-propellers platformed technology that possesses fluorescent and magnetic features and manifold thrombus targeting modes. The platform is capable of being guided and visualized remotely to specifically target thrombi, and it can be activated using near-infrared phototherapy along with an actuated magnet for magnetotherapy. In a murine model of thrombus lesion, this proposed multimodal approach showed an approximately 80 % reduction in thrombus residues. Moreover, the new strategy not only improves thrombolysis but also boosts the rate of lysis, making it a promising candidate for time-sensitive thrombolytic therapy. © 2023 The Authors

Fact-checking techniques can mitigate hallucinations in Large Language Models (LLMs), a prominent issue in specialized domains. As parameter-efficient techniques such as Low-Rank Adaptation (LoRA) can overcome substantial computational overhead, some studies have explored the integration of multiple LoRAs. While previous studies focus on parallel integration, this paper investigates methods to establish connections among multiple LoRAs. We create three reasoning datasets tailored to fact-checking and fine-tune individual LoRAs, allowing them to view and reason from diverse perspectives. Then, we explore strategies for allocating these reasoning LoRAs and introduce LoraMap, an approach to map connections between them. The results of the fact-checking task demonstrate that the performance of LoraMap is superior to LoraHub, an existing method for integrating LoRAs. LoraMap also outperforms with significantly fewer trainable parameters than LoraConcat, which concatenates LoRAs and further fine-tunes them. Copyright © 2024, The Authors. All rights reserved.

A physical picture of liquid–liquid phase separation of proteins

Liquid-liquid phase separation (LLPS) of proteins, by which they assemble and partition into a protein-dense phase and a protein-dilute phase, has caught much attention due to its essential roles in a variety of biological processes. Nevertheless, its mechanism remains to be unveiled. Here we develop a physical picture covering almost all the aspects of LLPSs of diverse systems. In our view, when only the proteins are looked at, one of the two phases is liquid-like and the other is gas-like. We relate LLPS to gas–liquid phase separation (GLPS) of simple fluids wherein the pivotal quantity is kBT (kB is the Boltzmann constant and T is the absolute temperature) divided by the absolute value of the minimum of interaction potential between fluid particles. GLPS occurs only if the pivotal quantity is sufficiently small. For LLPS, the interaction potential must be replaced by the potential of mean force (PMF) between protein molecules in aqueous solution. We do not explicitly consider aqueous solution, and its influence on properties of protein molecules is incorporated in PMF. PMF can reach its deep minimum when the two protein molecules associate. A physical interpretation is given for GLPS from a statistical-mechanics point of view, and it is extended to LLPS. In the extension, we discuss not only the similarities between the two phase separations but also the physical factors to be taken into account only in LLPS due to the fact that proteins are large molecules possessing polyatomic structures and they are immersed in aqueous solution. LLPS can be categorized as a biological self-assembly process. By reconsidering the results obtained in our earlier studies on biological self-assembly processes, we specify the entropic and energetic factors driving or opposing coacervation (association) of protein molecules followed by LLPS. We clarify the differences between LLPSs of folded proteins (i.e., proteins in the native states) and intrinsically disordered proteins. There c

Nickel-based compounds are widely applied as the active material for energy storage devices, owing to high theoretical capacity and easy-fabricated process. Bimetallic compounds having multiple redox states can provide abundant redox reactions for charge storage. Structure directing agent (SDA) can promote the preferable growth of active materials and to enhance energy storage abilities. In this work, NH4BF4 and NH4HF2 are firstly used as SDA to synthesize nickel-based compounds along with 2-methylmidozole in the one-step solution process for energy storage applications. The bimetallic compounds are synthesized by incorporating Al, Mn, Co, Cu and Zn salts in the precursor solution including the Ni salt. The system with Al, Cu or Zn possesses single metal compound and barely nickel compound. Mn and Co-incorporated systems present clear bimetallic components with nickel hydroxide. The highest specific capacitance (CF) of 1336.3 F/g (297.0 mAh/g) are achieved at 20 mV/s for the NiCo-based electrode, owing to the bimetallic feature and favorable two-dimensional sheet-like structures. An energy storage device is assembled using the NiCo-based compound and reduced graphene oxide electrodes. The maximum energy density of 10.5 Wh/kg at 0.3 kW/kg, and the CF retention of 78.5% and Coulombic efficiency of 85.2% are achieved after 10,000 times charge/discharge cycles. © 2023 Elsevier Ltd
