Abstract

Ambient energy harvesting has great potential to contribute to sustainable development and address growing environmental challenges. Converting waste energy from energy-intensive processes and systems (e.g., combustion engines and furnaces) is crucial to reducing their environmental impact and achieving net-zero emissions. Compact energy harvesters will also be key to powering the exponentially growing smart devices ecosystem that is part of the Internet of Things, thus enabling futuristic applications that can improve our quality of life (e.g., smart homes, smart cities, smart manufacturing, and smart healthcare). To achieve these goals, innovative materials are needed to efficiently convert ambient energy into electricity through various physical mechanisms, such as the photovoltaic effect, thermoelectricity, piezoelectricity, triboelectricity, and electromagnetic power transfer. By bringing together the perspectives of experts in various types of energy harvesting materials, this Roadmap provides extensive insights into recent advances and present challenges in the field. Additionally, the Roadmap analyzes the key performance metrics of these technologies in relation to their ultimate energy conversion limits. Building on these insights, the Roadmap outlines promising directions for future research to fully harness the potential of energy harvesting materials for green energy anytime, anywhere.

Abstract

The pathophysiology of Alzheimer’s disease (AD) is characterized by chronic, progressive neurodegeneration. One of the most obvious pathological feature of AD is the accumulation of soluble amyloid beta (Aβ) peptides in the brain. In this work, pridopidine, a selective sigma-1 receptor (S1R) antagonist, will be tested whether it ameliorates synaptic deficits induced by Aβ 1–42. If one can confirm detrimental effects of Aβ 1-42 oligomers on long-term potentiation (LTP) in the CA1 region of murine hippocampal slices, pridopidine will be co-treated in an attempt to reverse LTP deficits. Die Pathophysiologie der Alzheimer's Disease (AD) zeichnet sich vor allem durch die progressive Neurodegeneration aus. Es gibt Hinweise darauf, dass die Ursache des neurodegenerativen Prozesses in der löslichen Form des Amyloid beta (Aβ) Peptids liegt. In dieser Arbeit wird der selektive Sigma-1 Rezeptor (S1R) Antagonist Pridopidine in seiner Wirkung auf die Induktion der Langzeitpotenzierung (LTP) in der CA1-Region von murinen Hippocampus-Schnittpräparaten, sowohl in Abwesenheit als auch in der Gegenwart von Aβ 1-42 Oligomeren untersucht.

Abstract

Anion‐dependent differences in the electromechanical energy harvesting capability of perovskite halides have not been experimentally demonstrated thus far. Herein, anion‐dependent piezoelectricity and bending‐driven power generation in high‐quality methylammonium lead halide MAPbX3 (X = I, Br, and Cl) thin films are explored; additionally, anisotropic in situ strain is imposed to improve energy harvesting under tensile bending. After applying the maximum in situ strain of −0.73% for all the halide thin films, the MAPbI3 thin‐film harvester exhibited a peak voltage/current of ≈23.1 V/≈1703 nA as the best values, whereas MAPbBr3 and MAPbCl3 demonstrated ≈5.6 V/≈176 nA and ≈3.3 V/≈141 nA, respectively, under identical bending conditions. Apart from apparent ferroelectricity of tetragonal MAPbI3, origin of the piezoelectricity in both cubic MAPbBr3 and MAPbCl3 is explored as being related to organic–inorganic hydrogen bonding, lattice distortion, and ionic migration, with experimental supports of effective piezoelectric coefficient and grain boundary potential. Conclusively, piezoelectricity of the cubic halides is assumed to be due to their soft polarity modes and relatively low elastic modulus with vacancies contributing to space‐charge polarization. In the case of ferroelectric MAPbI3, the distortion of PbI6 octahedra and atomic displacement within each octahedron are quantitatively estimated. [ABSTRACT FROM AUTHOR]

31. Neuroprotective effects of tannic acid in the postischemic brain via direct chelation of Zn2+.

Abstract

Tannic acid (TA) is a polyphenolic compound that exerts protective effects under pathological conditions. The diverse mechanisms of TA can exert beneficial anti-oxidative, anti-inflammatory, and anti-cancer effects. Herein, we reported that TA affords robust neuroprotection in an animal model of stroke (transient middle cerebral artery occlusion; tMCAO) and exhibits Zn2+-chelating and anti-oxidative effects in primary cortical neurons. Following tMCAO induction, intravenous administration of TA (5 mg/kg) suppressed infarct formation by 32.9 ± 16.2% when compared with tMCAO control animals, improving neurological deficits and motor function. We compared the chelation activity under several ionic conditions and observed that TA showed better Zn2+ chelation than Cu2+. Furthermore, TA markedly decreased lactate dehydrogenase release following acute Zn2+ treatment and subsequently reduced the expression of p67 (a cytosolic component of NADPH oxidase), indicating the potential mechanism underlying TA-mediated Zn2+ chelation and anti-oxidative effects in primary cortical neurons. These findings suggest that anti-Zn2+ toxicity and anti-oxidative effects participate in the TA-mediated neuroprotective effects in the postischemic brain. [ABSTRACT FROM AUTHOR]
