Neutron reflectometry has long been a powerful tool to study the interfacial properties of energy materials. Recently, time-resolved neutron reflectometry has been used to better understand transient phenomena in electrochemical systems. Those measurements often comprise a large number of reflectivity curves acquired over a narrow range, with each individual curve having lower information content compared to a typical steady-state measurement.

Article Synopsis
  • Scientists studied how certain metal ions interact with special types of materials called redox polymers.
  • They found that one polymer, called PVFc, is better at separating one metal (ReO) from another (MoO) compared to another polymer (PFPMAm) when looked at closely.
  • The research helps us understand how to create better systems for recovering and recycling important metals from solutions.

Molecularly-selective metal separations are key to sustainable recycling of Li-ion battery electrodes. However, metals with close reduction potentials present a fundamental challenge for selective electrodeposition, especially for critical elements such as cobalt and nickel. Here, we demonstrate the synergistic combination of electrolyte control and interfacial design to achieve molecular selectivity for cobalt and nickel during potential-dependent electrodeposition.

Critical minerals are essential for the ever-increasing urban and industrial activities in modern society. The shift to cost-efficient and ecofriendly urban mining can be an avenue to replace the traditional linear flow of virgin-mined materials. Electrochemical separation technologies provide a sustainable approach to metal recovery, through possible integration with renewable energy, the minimization of external chemical input, as well as reducing secondary pollution.

Nanostructured polymer interfaces can play a key role in addressing urgent challenges in water purification and advanced separations. Conventional technologies for mercury remediation often necessitate large energetic inputs, produce significant secondary waste, or when electrochemical, lead to strong irreversibility. Here, we propose the reversible, electrochemical capture and release of mercury, by modulating interfacial mercury deposition through a sulfur-containing, semiconducting redox polymer.

Mild encephalitis with reversible lesion in the splenium is a clinicoradiological syndrome characterized by a variegated symptomatology with a solitary mass in the central portion of the splenium of the corpus callosum. Complete spontaneous resolution is the hallmark of this syndrome, though its pathogenesis is still unknown. We describe the clinical picture of a 51-year-old woman who developed a partial sensitive seizure, with MRI evidence of a lesion localized in the posterior portion of the corpus callosum.

Tick borne encephalitis virus infection usually shows a biphasic course. In the first stage of illness symptoms are similar to a flu-like syndrome, then after a defervescence period, fever may represent with neurological manifestations ranging from mild meningitis to severe encephalomyelitis. We report the clinical case of an adult man presented with an acute proximal hyposthenia, severe hyperckemia, clinical and laboratoristic evidence of acute tick borne virus infection.

Post-malaria neurological syndrome (PMNS) is a rare complication of malaria. It follows recovery from an episode of Plasmodium falciparum malaria and is characterised by symptoms and signs of encephalopathy. Patients usually improve without any specific treatment.

Background: Artery dissection is an unusual cause of ischemic stroke, particularly frequent among young patients. The aim of this study was to collect epidemiological data on artery dissection in a hospital-based community, set up a diagnostic protocol and discover outcome predictors.

Methods: Among patients suffering from cerebral infarction resident in our country, those with clinical and radiological features suggestive of artery dissection were selected.

Antithyroid antibodies and circulating immune complexes (CIC) were found in the CSF of six patients with Hashimoto's encephalopathy (HE) but not in the CSF of 21 controls. The synthesis of autoantibodies and CIC was intrathecal and their titers were independent of the patients' clinical status or therapy. Their presence in the CSF of patients with acute or subacute encephalopathy may be useful in diagnosing HE.

Objectives: To report and discuss the neuropsychological deficits and neuroimaging findings in a patient with probable Marchiafava-Bignami disease.

Design And Method: A right-handed woman with chronic alcoholism demonstrated mutism, impaired comprehension of spoken language, alexia, and right-handed agraphia. The syndrome of interhemispheric disconnection was manifested by left-handed deficit of constructional ability and agraphia.
