V496 Scuti: Detection of CO emission and dust shell in a moderately fast Fe II nova

open access: yes, 2013
We present near-infrared and optical observations of moderately fast FeII-class Nova Scuti 2009 (V496 Sct) covering various phases; pre-maximum, early decline and nebular, during the first 10 months after its discovery followed by limited observations up to 2011 April.

Rod‐Like PLGA Microrobots with Enhanced Motion and Biodegradation for Magnetic‐Guided Drug Delivery

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents drug‐loaded Poly (lactic‐co‐glycolic acid) (PLGA) microrobots fabricated from an oil‐in‐water (O/W) emulsion of PLGA, Fe3O4 nanoparticles, and Adriamycin (DOX). They are formed by film‐forming and stretching microrobots, and exhibit motion analyzed via video‐snapshots, speed graphs, and shape changes, advancing targeted for drug ...

Language‐Guided Robot Grasping Based on Basic Geometric Shape Fitting

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents a language‐guided, model‐free grasping framework that integrates multimodal perception with primitive‐based geometric fitting. By explicitly modeling object geometry from RGB‐D data, the method enables semantically controllable grasp pose generation and achieves robust performance in both structured and cluttered real‐world ...

Electrochemical Protection of Cyanobacterial Cells from Molecular Oxygen Enables Sustained PhotoH2 Production

open access: yesAngewandte Chemie International Edition, EarlyView.
Photosynthetic microorganisms can be used to perform H2 evolution driven by light. However, a crucial limitationlies in the associated generation of molecular oxygen as a by‐product of photosynthesis, which compromises the activity of the biocatalyst performing H2 production, i.e., the hydrogenase.

Noninvasive Glucose Detection with Biodegradable Electrodes from Rice Starch Functionalized with a Carbon Quantum Dot/Nickel Oxide Nanocomposite

open access: yesAnalysis &Sensing, EarlyView.
The graphical abstract shows an eco‐friendly approach to fabricating a biodegradable electrochemical sensor. Carbon quantum dot/nickel oxide (CQD/NiO) nanocomposites are synthesized using Aloe arborescens leaf extract, which served as a natural reducing and stabilizing agent.

Converting Durian Husk Into Adsorbent Beads for Methylene Blue Adsorption: Synthesis, Kinetics, Isotherms, and Reusability

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Environmental pollution from textile dyeing wastewater, particularly the discharge of harmful dyes like methylene blue (MB), poses a significant challenge. This study presents an innovative solution for dyeing wastewater treatment by utilizing durian husk, an agricultural waste, as an adsorbent for MB removal.

An extremely fast fading population II dwarf nova candidate: caught spectroscopically on the rise

open access: yes
We present AT2022kak, a rapidly evolving optical transient discovered by the KiloNova and Transients Program (KNTraP). This interesting burst exhibited extremely fast evolution, with a large amplitude blue outburst of m > 3.3 in a single night, and a rapid fade back to quiescence in the following two nights.

Sustainable Graphene Oxide–Intercalated Bentonite Composite for the Effective Removal of Imidacloprid From Water: Adsorption Performance, Isotherm, and Kinetics

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.
