High‐Performance Electrocatalysts of Potassium Lactate Oxidation for Hydrogen and Solid Potassium Acetate Production

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Potassium lactate, produced from polylactic acid plastic waste, is oxidized to potassium acetate on an anode using Ni(Co)OOH as the electrocatalyst, while hydrogen is simultaneously generated at the cathode, through a highly efficient industrial‐scale electrolysis system.

Nontrivial solutions of systems of nonlocal Caputo fractional BVPs [PDF]

open access: yesGlobal and Stochastic Analysis, Vol. 5, No. 1, June (2018), 31-38, 2016
We discuss the existence, non-existence and multiplicity of nontrivial solutions for systems of Caputo fractional differential equations subject to nonlocal boundary conditions. Our methodology relies on classical fixed point index and we make use of recent results by Infante and Pietramala.

Patterned progression of bacterial populations in the premature infant gut

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2014
Significance It is increasingly apparent that bacteria in the gut are important determinants of health and disease in humans. However, we know remarkably little about how this organ transitions from a sterile/near-sterile state at birth to one that soon ...

ATROPHY OF INFANTS [PDF]

open access: yesArchives of Pediatrics & Adolescent Medicine, 1912
The term "atrophy of infants" was formerly used to designate a disease sui generis . It was characterized clinically by the fact that children, who had developed well up to a certain time, gradually began to fail and eventually died, presenting the picture of a progressive and often extreme grade of emaciation.

Shortwave Infrared Light Detection and Ranging Using Silver Telluride Quantum Dots

open access: yesAdvanced Materials, EarlyView.
Post‐synthesis surface engineering and doping control significantly improve the performance of Ag₂Te CQD photodiodes, achieving a low dark current of 450 nA cm−2 at −0.5 V, an LDR exceeding 150 dB, and a rapid response speed of ≈25 ns. A proof‐of‐concept LiDAR demonstration in the SWIR using a nanosecond diode laser, achieves decimetre‐level resolution

fMRI reveals neural activity overlap between adult and infant pain

open access: yeseLife, 2015
Limited understanding of infant pain has led to its lack of recognition in clinical practice. While the network of brain regions that encode the affective and sensory aspects of adult pain are well described, the brain structures involved in infant ...

Leveraging Grain Boundary Effects for Nanostructured Electrode Layers in Symmetric Solid Oxide Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Nanocrystalline thin‐films of lanthanum chromite exhibit extraordinary properties of fast oxygen kinetics. These properties are due to the peculiar chemistry of grain boundaries and can be harnessed for fabricating symmetric electrochemical devices with self‐healing properties. Abstract While grain boundary engineering is attracting great interest as a

A Flexible‐Substrate 5‐µm‐Diameter Needle Electrode: Minimizing Neuronal Death and Enabling Year‐Long Neural Recording

open access: yesAdvanced Materials Interfaces, EarlyView.
An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.
