Enzyme‐Activated MRI for In Vivo Glucose Imaging via a Biodegradable Chromium Nanoprobe

open access: yesAdvanced Science, EarlyView.
Enzyme‐activated MRI (eaMRI) using a biodegradable CrGOx@Lip nanoprobe enables glucose‐specific imaging in vivo. GOx catalyzes glucose oxidation, triggering in situ formation of paramagnetic chromium gluconate and amplifying T1. This radiation‐free strategy maps tumor glucose uptake via the Warburg‐effect, quantifies hepatic glucose accumulation in ...

Investigation of the Lithium Extraction Mechanism from LiNi0.6Mn0.2Co0.2O2 by Using Operando Neutron Diffraction in an All‐Solid‐State Battery

open access: yesAdvanced Energy Materials, EarlyView.
All‐solid‐state batteries (ASSB) are promising for high‐energy applications. Using a newly designed electrochemical cell, this study demonstrates reversible Li+ insertion/extraction in a thick ASSB and enables operando neutron diffraction. The results reveal structural evolution and H1‐H2 phase coexistence in LiNi0.6Mn0.2Co0.2O2 (NMC622), while ...

Fluorine‐18‐Labeled Nucleotide Analogs Targeting Ecto‐5'‐Nucleotidase (CD73) for Positron Emission Tomography Imaging of Solid Tumors

open access: yesAngewandte Chemie, EarlyView.
Fluorine‐18‐labeled CD73 inhibitor [18F]PSB‐19427 enables noninvasive PET mapping of CD73 overexpression in triple‐negative breast (TNBC) and pancreatic cancer. For [18F]PSB‐19427, specific binding in human tumor tissues, favorable biodistribution with prolonged blood retention, robust tumor uptake, and superiority to [18F]FDG in a TNBC model ...

Investigation of radioactivity-induced backgrounds in EXO-200

open access: yes, 2015
The search for neutrinoless double-beta decay (0{\nu}{\beta}{\beta}) requires extremely low background and a good understanding of their sources and their influence on the rate in the region of parameter space relevant to the 0{\nu}{\beta}{\beta} signal.

Design and optimization of processes for recovering rare earth elements from end‐of‐life permanent magnets

open access: yesAIChE Journal, EarlyView.
Abstract Recovery of rare earth elements (REEs) from end‐of‐life (EOL) products represents a strategic opportunity to strengthen the domestic supply chain for rare earth elements. This work presents a superstructure‐based optimization framework for finding the most economical processing pathway for different EOL rare earth permanent magnets (REPMs ...

Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling

open access: yesAngewandte Chemie, EarlyView.
The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

Effects of formation properties in one-proton radioactivity

open access: yes, 2012
It is shown that the proton formation probability, extracted from experimental data corresponding to one-proton radioactivity, is divided into two regions when plotted as a function of an universal parameter.

Real‐time fault detection in multicomponent nuclear‐waste slurries through data fusion of spectroscopic sensors

open access: yesAIChE Journal, EarlyView.
Abstract Three instruments–Raman spectroscopy, attenuated total reflectance–Fourier transform infrared spectroscopy, and focused beam reflectance measurement–were used to detect sensor faults, mixing faults, and unanticipated chemistry in a system of multicomponent slurries.
