From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

Chemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

An assessment of N, P, Fe, Zn, Ni and Mo limitation on suspended nutrient diffusing substrates in nearshore areas of Lake Michigan and Lake Erie

Journal of Freshwater Ecology
In large lakes, metal availability sometimes limits the acquisition of nutrients (nitrogen, N and phosphorus, P) in offshore waters that are relatively isolated from tributaries and sediments.

Laser neoureterocystostomy to treat ectopic ureters

Equine Veterinary Journal, EarlyView.
Abstract Background Ureteral ectopia is an uncommon but clinically important congenital abnormality in horses. If left untreated, it can lead to persistent dermatitis, urinary tract infections, and failure to thrive. Surgical correction is necessary, but traditional approaches have produced mixed results with high morbidity.

Satellite Retrievals of Karenia brevis Harmful Algal Blooms in the West Florida Shelf Using Neural Networks and Comparisons with Other Techniques

Remote Sensing, 2016
We describe the application of a Neural Network (NN) previously developed by us, to the detection and tracking, of Karenia brevis Harmful Algal Blooms (KB HABs) that plague the coasts of the West Florida Shelf (WFS) using Visible Infrared Imaging ...

CO2 capture by accelerated weathering of limestone using waste limestone at elevated CO2 concentrations

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Accelerated weathering of limestone (AWL) using waste limestone (WL) for industrially relevant CO2 capture remains underexplored. Previous studies on potable water‐operated AWL have mainly examined idealised conditions, such as the use of high‐purity limestone or relatively low CO2 concentrations, which may not reflect selected ...

The HABS Culture of Documentation with an Analysis of Drawing and Technology [PDF]

, 2011
The Historic American Buildings Survey (HABS) is one of the oldest federal programs in the United States. In 1933, the HABS culture of documentation started with the mission of creating a permanent record of the nation's architectural heritage. Since the

Teaching of Engine‐Driven Root Canal Treatment Globally—A “Questionnaire Based” Study

Journal of Dental Education, EarlyView.
ABSTRACT Objectives The teaching of root canal therapy, particularly engine‐driven root canal preparation, varies across dental schools. Therefore, this qualitative, questionnaire‐based study aimed to identify preferred engine‐driven endodontic systems at top‐ranked dental universities and to explore the reasons behind their selection.

ANALYSIS OF CAUSING FACTORS ON THE APPEARANCE OF HABS IN COASTAL WATER OF MAKASSAR [PDF]

, 2019
HABs were types of phytoplankton considered dangerous in the sea. Its appearance was triggered by an increase in nutrients and the presence of physical and chemical factors in the optimal conditions to support its growth. For that reason, research on the

Thermische Sicherheit in Lithium‐Ionen‐Batterien: Dem Batteriebrand vorbeugen

Physik in unserer Zeit, EarlyView.
Ein Elektrofahrzeug wird nach einem Unfall abgestellt. Trotz leicht beschädigter Batterie scheint die Situation unter Kontrolle. Doch im Inneren der Batterie kann eventuell eine thermisch getriebene Kettenreaktion ablaufen, deren Folgen erst Stunden später sichtbar werden.

Oberflächencharakterisierung auf atomarer Ebene: Vom Sehen einzelner Atome zum Verständnis chemischer Prozesse

Physik in unserer Zeit, EarlyView.
Sehen ist der erste Schritt in Richtung Verstehen. Dieses Prinzip gilt von der Beobachtung ferner Galaxien bis hin zur Untersuchung einzelner Atome und hält damit über viele Größenordnungen. Heutzutage ermöglichen moderne Mikroskope die Beobachtung einzelner Atome und sogar die gezielte Kontrolle chemischer Reaktionen einzelner Moleküle ...
