Summary: SiNW-FET sensors have been developed as highly sensitive detectors for a variety of molecules due to their exceptional electrical properties. The bottom-up approach allows for the synthesis of silicon nanowires in a range of diameters, while the top-down approach utilizes advanced lithography techniques to fabricate SiNW out of high-quality SOI wafers. Despite the advancements in fabrication techniques, sensor-to-sensor variation remains a challenge for large-scale production in commercial applications.

Summary: By combining biotemplate and neutral beam etching processes, we fabricated high aspect ratio Si nanopillar arrays to investigate the wettability with and without surface silicon oxide film. The presence of silicon native oxides in the gaps resulted in super-hydrophilicity, while selectively removing the oxides led to high hydrophobicity in the Si nanopillars. This study demonstrates the controllable surface wettability achieved by manipulating the gap sizes and the presence of silicon native oxides on the surfaces.

Summary: Piezoresistive strain gauges provide precise electronic readout of mechanical deformations and are now being scaled down for nanotechnology applications. We conducted experiments to study the physical attributes of nanoresistors at different frequencies, finding that the gauge factor increased monotonically with frequency, possibly due to unexpected physics phenomena.

Summary: Silicon nanowire (SilNW), with its distinctive optical, mechanical, and electrical characteristics, has emerged as a potential sensing nanomaterial. It has found applications in high-sensitive sensors due to its large surface-volume ratios and high sensitivity. SilNW FET-based sensors, known for their high charge sensitivity, have been extensively used for sensing various chemical and biological species. This study focuses on the sensing performance and applications of different SilNW biosensors, gas sensors, chemical sensors, metal ion sensors, as well as the latest developments and sensing performance of SilNW-based Covid-19 sensors.

Summary: Control of surface defects and impurity doping is crucial for semiconductor nanowires-based devices. In this study, p-Si/i-Ge core-shell nanowires with radial heterojunctions were fabricated to suppress impurity scattering. Heat treatment to repair surface damage and oxidation and chemical etching prior to shell formation reduced the surface roughness and diameter of the nanowires. Furthermore, hole gas accumulation was observed in the i-Ge layers, which is important for suppressing impurity scattering.

Summary: A technological process was developed to integrate silicon-nanowire-based field-effect nanodevices on a silicon-on-insulator (SOI) substrate. The fabrication of SiNW-FET and SiNW-ISFET devices was achieved through a double reactive ion etching process and a gate process involving SiO2 thermal oxidation growth and Al2O3 atomic layer deposition. The devices exhibited excellent electrical characteristics and demonstrated sensitivity in pH analysis at the submicronic scale.

Summary: In this study, it was found that switchgrass adapts well to marginal soils with low phosphorus content. The research also discovered that phosphorus limitation affects the chemical composition and quality of switchgrass, and different soil conditions impact nutrient allocation strategies, which in turn affects biomass yields in the subsequent year. The use of a machine learning model effectively addresses these challenges and provides important information about switchgrass growth conditions and feedstock quality.

Summary: Autonomous experimentation is a growing field of research that focuses on autonomous vehicles, combinatorial discovery in materials science and drug discovery, and iterative research loops. However, applying autonomous approaches to high-dimensional mapping technologies like scanning hyperspectral imaging of biological systems is challenging due to sample complexity and heterogeneity. This article explores adaptive sampling algorithms and surrogate modeling to define autonomous adaptive data acquisition as a flexible building block for future biological imaging experimentation. It discusses recent implementations of autonomous adaptive data acquisition for scanning hyperspectral imaging, emphasizes the design variation from a goal-oriented perspective, and presents a modular architecture to address time resolution challenges in high-dimensional scanning hyperspectral imaging of nonequilibrium dynamical systems.
