N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

Chemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.

A High‐Performance Oxidized Graphene for Dendrite‐Free Anodes and Kinetically Enhanced Cathodes of Aqueous Zn‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Oxidized graphene rich in carboxylic acid groups obtained via a simple electrochemical exfoliation route is shown to tackle the main challenges of aqueous Zn‐ion batteries (AZIBs), specifically short Zn anode cycle life and sluggish cathode reaction kinetics.

Pulmonary inflammation decreases with ultra-protective ventilation in experimental ARDS under VV-ECMO: a positron emission tomography study

Frontiers in Medicine
BackgroundExperimentally, ultra-protective ventilation (UPV, tidal volumes [VT] < 4 mL.kg−1) strategies in conjunction with veno-venous extracorporeal membrane oxygenation (VV-ECMO) are associated with lesser ventilator-induced lung injuries (VILI ...

Assessment of Mechanical Properties of Concrete by Combining Digital Image Correlation and Ultrasonic Pulse Velocity

Buildings
The ultrasonic pulse velocity (UPV) method is widely used for determining the dynamic modulus of elasticity of concrete. Traditionally, this approach requires assuming Poisson’s ratio (arbitrary values ranging from 0.1 to 0.25), regardless of the actual ...

An End Degree for Digraphs

Journal of Graph Theory, EarlyView.
ABSTRACT In this paper we define a degree for ends of infinite digraphs. The well‐definedness of our definition in particular resolves a problem by Zuther. Furthermore, we extend our notion of end degree to also respect, among others, the vertices dominating the end, which we denote as combined end degree.

Beta Human Papillomaviruses Seropositivity and the Association With Cutaneous Squamous Cell Carcinoma—A Systematic Review and Meta‐Analysis

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Cutaneous squamous cell carcinoma (cSCC) is one of the most common nonmelanoma skin cancers, with increasing incidence globally. Beta genus human papillomaviruses (β‐HPVs), particularly in immunocompromised individuals, have been implicated in the development of cSCC. However, the strength of association between β‐HPV seropositivity

Effect of concrete waste dust on the flowability, compressive strength, and ultrasonic pulse velocity of mortar

Next Materials
Construction and demolition (C&D) waste, which accounts for approximately 25–30% of total urban solid waste, along with the high CO2 emissions from the global cement industry, presents a major challenge to achieving sustainable development. One promising
