Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]

, 2005
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.

Alkynyltriazenes in Photochemical Metal‐Free Doyle–Kirmse Rearrangements

Angewandte Chemie International Edition, EarlyView.
A metal‐ and additive‐free photocatalytic Doyle–Kirmse reaction of alkynyl triazenes is described, proceeding via cyanocarbene intermediates. This strategy enables the efficient construction of highly substituted asymmetric carbon centers with broad substrate scope, delivering synthetically valuable nitriles.

Synergism and Radicals Dynamics in the Efficient Degradation of Basic Blue 41 via UV/Chlorine Process: Dependence on Processing Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The UV/chlorine process, a promising advanced oxidation process, demonstrates remarkable synergism and radical dynamics for the efficient degradation of Basic Blue 41 (BB41). This study investigates the effects of processing conditions, including solution temperature (25°C–45°C), pollutant dose (10–40 mg/L), chlorine concentration (100–1000 μM)

Fe(II)/Chlorine‐Driven Advanced Oxidation of Textile Dyes in a Tubular Microreactor: Continuous‐Flow Performance and Matrix Effects

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The Fe(II)/chlorine system has emerged as a promising advanced oxidation technology for water treatment, yet its application in continuous‐flow systems remains unexplored. This study presents the first comprehensive investigation of the Fe(II)/chlorine process in a tubular microreactor, a setup that significantly enhances mass transfer and ...

Evaluation of Spontaneous Overtime Methemoglobin Formation in Post-Mortem Blood Samples from Real Cases in Critical Storage Conditions

Toxics
Nitrite/nitrate poisoning is an emerging problem, with an ongoing escalation of reported self-administration with suicidal intent in several countries. Nitrites toxicity mainly consists of their interaction with hemoglobin (Hb), causing its oxidization ...

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...
