A Comprehensive Study of Quantum Dots: Ranging From Synthesis to Applications in Electrochemical Biosensors in the Detection of Biomolecules, Gastrointestinal Diseases, and Electrophysiology

Nano Select, EarlyView.
Quantum dots (QDs) typically refer to extremely small semiconductor particles, often no larger than 10 nm. The development of efficient biosensors for the sensitive and selective detection of biomolecules is essential for fundamental research in analytical chemistry, biomedicine, clinical diagnosis, and electrophysiology.

Extrasolar Planets and Their Host Stars

, 2017
In order to understand the exoplanet, you need to understand its parent star. Astrophysical parameters of extrasolar planets are directly and indirectly dependent on the properties of their respective host stars.

High‐Performance Oxidation and Nanomolar Detection of Phenylhydrazine Using a 6‐Hydroxyflavone‐Based Molecular Electrocatalyst Functionalized Multiwalled Carbon Nanotube in Batch Injection Analysis

ChemistryOpen, EarlyView.
This study presents a novel, rapid method for in situ functionalization of carbon electrodes using redox‐active form of the 6‐hydroxyflavone. The resulting multiwalled carbon nanotubes with redox‐active HFLA (MWCNT@HFLA‐Redox) electrode enables sensitive, selective detection of toxic phenylhydrazine, with excellent performance (limit of detection: 7 nM)

Spectral Energy Distributions of Be and Other Massive Stars

, 2010
We present spectrophotometric data from 0.4 to 4.2 microns for bright, northern sky, Be stars and several other types of massive stars. Our goal is to use these data with ongoing, high angular resolution, interferometric observations to model the density

Low Resistivity Sputter Deposited SnOx Thin Films: An Indium‐Free Transparent Conductive Oxide?

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
For sustainable, mass‐producible optoelectronic devices, indium‐free transparent conductive oxides are essential. This study examines how oxygen content during sputter deposition and thermal treatments influences the optoelectrical properties of amorphous SnOx films.

NICMOS Spectrophotometry and Models for A-Stars

, 2008
Absolute flux distributions for eight stars are well measured from 0.8-2.5mu m with NICMOS grism spectrophotometry at a resolution of R~100 and an accuracy of 1-2%. These SEDs are fit with Castelli & Kurucz model atmospheres; and the results are compared

Hydrophobic Radiative Cooling using Zein‐Functionalized Polyvinyl Alcohol Nanofibers with Dielectric Nanoparticles

Small, EarlyView.
A high‐performance radiative cooling material is fabricated from hydrophilic polyvinyl alcohol using a green, scalable method. The resulting nanofiber membrane exhibits robust hydrophobicity alongside high solar reflectance (91.7%) and thermal emissivity (96.9%). This combination enables a 6.9 °C sub‐ambient temperature drop, making it ideal for energy‐

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

Smart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.
