A Non‐Equilibrium Flame Aerosol Process to Create High‐Entropy MOFs

S T Liu, Jiashun Liang, Mohd Ashhar Khan, Shaon Das et autres

High-entropy alloys and ceramics have demonstrated promising applications in the past decade. Ultrafast heating and cooling can kinetically trap immiscible elements into solid solutions, expanding the compositional space and optimizing the properties of high-entropy materials. However, the extreme temperatures required by these …

In Situ Transferrin-Mediated Sandwich-like Targeting with Engineered Ginger-Derived Extracellular Vesicles for Precision Oral Chemotherapy of Colorectal Cancer

Weilin Lv, S Li, Zhaohan Wei, Xin Li et autres

Oral chemotherapy for colorectal cancer (CRC) is limited by poor tumor selectivity and microenvironment-driven resistance. Addressing these limitations demands materials that integrate tumor-selective targeting with immune microenvironment modulation. Here, clinical analysis of CRC specimens revealed pronounced transferrin (Tf) enrichment in CRC-associated intestinal …

Real-Time Standoff Detection of Trace Levels of PFAS in Water Using Photothermal Nanomechanical Spectroscopy

Yaoli Zhao, Kyle Leatt, Krishnamurthy Prabakar, Diana S. Aga et autres

Real-time detection of hazardous chemicals in water that appear at parts-per-trillion level concentrations with high sensitivity and selectivity is challenging. Achieving ultrahigh sensitivity using techniques based on immobilized receptors and electrochemistry requires the use of preconcentrators for sample enrichment, which imposes a …

Advanced Photothermal Spectroscopy for Trace PFAS Detection

Yaoli Zhao, N.K. Jannabhatla, Thomas George Thundat

The widespread industrial and consumer use of per- and polyfluoroalkyl substances (PFAS) has led to their persistent presence in the environment, driven by their robust carbon-fluorine bonds and bioaccumulative properties. This contamination poses serious health and ecological risks, making real-time, selective, and …

Magnetic Iron Oxide Seed-mediated Formation of 2D ZnO Core–shell Nanostructures

Zhengxi Xuan, Yaoli Zhao, Shuo Liu, Avisek Dutta et autres

Metal oxide core–shell nanocomposites can derive bifunctionality from combining two or more intimately coupled domains of different dimensional nanomaterials. These properties can be tuned by adjusting the composition and reaction conditions to modulate the structure–function relationship. However, the colloidal synthesis of metal …

Chemical Sensing Using Thermocouple Cantilevers: Pushing Toward Quantum Sensing

Yaoli Zhao, Patatri Chakraborty, Ali Passian, Thomas George Thundat

Detecting and quantifying minuscule quantities of chemicals with high molecular selectivity remains a measurement challenge. We present a photothermal spectroscopic method that exploits the Seebeck effect in a finely engineered nanoscale thermocouple junction at the apex of a microcantilever. The temperature variations …

Rapid Detection of Trace Levels of Perfluorooctanoic Acid Using Photothermal Cantilever Deflection Spectroscopy

Yaoli Zhao, Kyle Leatt, P. Krishna Murthy, Thomas George Thundat

Real-time detection of chemical contaminants in the environment using portable, low-cost sensors with high selectivity, sensitivity, reproducibility, and wide dynamic range is challenging because of the complex nature of analytes and sample matrices. The challenge is exacerbated when the targeted chemical contaminants …

Deterministic Fabrication of Liquid Metal Nanopatterns for Nanophotonics Applications

Md. Abdul Kaium Khan, Yaoli Zhao, Shreyan Datta, Puspita Paul et autres

Gallium-based liquid metals (LMs) are widely used for stretchable and reconfigurable electronics thanks to their fluidic nature and excellent conductivity. These LMs possess attractive optical properties for photonics applications as well. However, due to the high surface tension of the LMs, it …

(Sensor Division Student Research Award) Ultra-Sensitive Photothermal Spectroscopy for Attogram-Level Detection

Yaoli Zhao, Patatri Chakraborty, Ali Passian, Thomas George Thundat

Molecular-level spectroscopy is crucial for sensing and imaging applications, yet detecting and quantifying minuscule quantities of chemicals remains a challenge, especially when they surface-adsorb in low numbers. Here, we introduce a photothermal spectroscopic technique that enables high selectivity sensing of adsorbates with …

Platinum Decorated Palladium Nanowires for Room‐Temperature Hydrogen Detection

Abhishek Kumar, Yaoli Zhao, Sadaf Mohsenifard, Vaishali Maheshkar et autres

Abstract The use of hydrogen as an energy carrier will require low‐cost, low‐power hydrogen sensors. Toward this goal, penta‐twinned palladium nanowires (Pd NWs) are synthesized and fabricated sensors from them by drop‐casting. Pd NWs drop‐cast onto an interdigitated electrode (IDE) gave a …
