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

open access: yesNano 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.

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

The bZIP3‐AS1 complex promotes CONSTANS‐induced FLOWERING LOCUS T activation in a daylength‐dependent manner

open access: yesJournal of Integrative Plant Biology, EarlyView.
The Arabidopsis bZIP3 protein works in conjunction with ASYMMETRIC LEAVES1 to facilitate the function of the CONSTANS protein in activating FLOWERING LOCUS T expression at the end of the day in a day length‐dependent manner. ABSTRACT Plants monitor daylength to synchronize their flowering time with their surroundings and thus maximize reproductive ...

Iron and copper sulfides in asteroid (162173) Ryugu: Formation conditions and a comparison to the CI and CY chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 506-528, March 2025.
Abstract JAXA's Hayabusa2 sample return mission visited the volatile‐rich carbonaceous (C‐type) asteroid (162173) Ryugu with the aim of ground‐truthing remote observations, returning a pristine sample from a C‐type asteroid, and strengthening links between asteroids and the meteorite collection. Here, we have conducted a systematic study of coarse (>10

Methyl jasmonate elicits rapid changes in carbon and nitrogen dynamics in tomato.

open access: yesNew Phytologist, 2010
• Evidence is emerging to support the notion that in response to herbivory, plants undergo changes in their primary metabolism and are able to fine-tune the allocation of new and existing resources and temporarily direct them to storage organs.
