Revolutionizing energy harvesting: A comprehensive review of thermoelectric devices
Authors: Irfan Syed , Khan Sadaf Bashir , Yang Zhiyuan 
Published: June 2024

AbstractThe necessity for a shift to alternative forms of energy is highlighted by both approaching consequences of climate change and limited availability of fossil fuels. While a large portion of energy required can be generated by solar and wind, a diverse, sustainable energy generation mix is still necessary to meet our energy needs. By capturing otherwise lost heat energy and turning it into valuable electrical energy, thermoelectric can play a significant part in this. Using the Seebeck effect, thermoelectric generators (TEG) have established their capability to transform thermal energy into electrical energy directly. Furthermore, because they do not include chemical compounds, they are silent in operation and can be built on various substrates, including silicon, polymers, and ceramics. Moreover, thermoelectric generators have a long operational lifetime, are position independent, and may be integrated into bulky, flexible devices. However, the low conversion efficiency of TEG has confined their broad application, hampering them to an academic subject. Until now, recent developments in thermoelectric generators and devices are presuming the technology to catch its place among state-of-the-art energy conversion systems. This review presents the commonly used methods for producing thermoelectric modules (TEMs) and the materials currently studied for TEMs in bulk and printed thermoelectric devices.

Published: June 2024

Abstract
In this manuscript, we present a facile and friendly sol-gel method to prepare bare and Zn-doped SnO2 nanoparticles and measured the photocatalytic performance of the materials by measuring the degradation of MB dye under UV light irradiation. A variety of analytical techniques were employed to characterize the materials, including X-ray diffraction, UV–Vis spectroscopy, Photoluminescence (PL), Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM). The X-ray diffraction (XRD) analysis reveals the presence of tetragonal SnO2 nanostructures. The average crystallite size of the bare SnO2 nanostructures was found to be 7.4 nm, but the addition of Zn dopant caused the size to increase to 10.5 nm. PL studies shows that the majority of emission energies fell within the SnO2 NPs’ band gap, indicating defects related to oxygen vacancies or Sn interstitials. The morphological analysis of SEM exhibits the various forms of SnO2 nanostructures which are densely agglomerate. The photocatalytic activity of the SZ10 NPs was found to be MB (88 %). The results showed that the Zn doped SnO2 exhibited good photocatalytic activity.
New insight into the phase changes of gypsum

Published: June 2024

AbstractThe phase changes of gypsum were considered to be sufficiently understood for a long time. However, due to the increasing importance of gypsum recalcination (connected with the planned closure of thermal power plants resulting in a lack of FGD gypsum) and new detailed research associated with it, gaps in the current knowledge have been discovered. This paper clarifies phenomena occurring during the production of gypsum binder, anhydrite, and potentially eco-friendly calcium sulfate-based ceramics at 22–1300 °C by in-situ XRD, thermal analysis, and SEM. It was found that undesirable insoluble anhydrite II arises even in the temperature range from 40 to 90 °C despite the current state-of-the-art. New knowledge about the existence of the individual phases, microstructure (cracking of crystals; fragmentation and sintering of anhydrite AII at temperatures above 700 °C when a ceramic-like material is formed), and their external consequences (changes in moisture and heat transport properties) has been gained.
Low-Dose Atropine-Triggered Atrial Fibrillation in Chlorpyrifos Plus Cypermethrin Poisoning: A Rare Case Report and Review of Literature
Authors: Gheshlaghi Farzad , Dorooshi Gholamali , Samsam-Shariat Shiva , Eizadi-Mood Nastaran , Etemad Leila , Pirmoradian Pedram , Moshiri Mohammad 
Published: June 2024

Background: Poisoning with Organophosphates (OP) and/or Pyrethroids (PYR) pesticides is common. We present a rare case of OP+PYR poisoned patient who suffered from Atrial Fibrillation (AF) at the beginning of treatment by a low dose of atropine and reviewed the literature.
Case Presentation: A 50-year-old man had ingested about 5-10 ml of a mixture of chlorpyrifos/cypermethrin. Half an hour later, he went to the rural hospital and 2 hr later, after gastrointestinal decontamination, he was referred to the clinical toxicology department with normal vital signs except normal sinus tachycardia [Heart rate (HR)]=105. On admission, he had nausea, vomiting, diarrhea, mild sialorrhea, symmetric mid-size pupils, wet skin, and bilateral moist rales in his lungs. His cardiac rhythm changed to rapid AF (HR >140 beats/min) after treatment with 3 mg midazolam followed by 0.3 mg of atropine (0.1 mg every 1-3 min). Atropine administration was discontinued and he was treated with 0.5 mg of digoxin. 6 hr later, his arrhythmia disappeared and all cardiac and laboratory evaluations changed to normal except reduced serum cholinesterase activity.
Conclusion: AF may be induced by Organophosphates (OP) and Pyrethroids (PYR) intoxication or during the treatment by atropine. We could not find any known risk factor (cardiac or medical issues) for AF in the current case. It may be suggested that poisoning with OP, PYR (alone or mixed) or atropine (in general or in low dose), or combination is the trigger of AF. However, AF is not life threating and can easily cure by antiarrhythmic therapy.

O objeto de análise é a linguagem memética nas redes sociais na internet como meio de apropriação tecnológica e de cultura de compartilhamento de mensagens. Utilizo como referencial teórico e metodológico a análise crítica do discurso formulada por Norman Fairclough (1989, 1992, 2001). Concluo que os memes podem se constituir num instrumento de mediação cultural e de análise crítica da política brasileira e também como um recurso que não deve ser desvinculado das práticas educativas nas instituições escolares.

Abstract

Remorins are multifunctional proteins, regulating immunity, development and symbiosis in plants. When associating to the membrane, remorins sequester specific lipids into functional membrane nanodomains. The multigenic protein family contains six groups, classified upon their protein-domain composition. Membrane targeting of remorins occurs independently from the secretory pathway. Instead, they are directed into different nanodomains depending on their phylogenetic group. All family members contain a C-terminal membrane anchor and a homo-oligomerization domain, flanked by an intrinsically disordered region of variable length at the N-terminal end. We here combined molecular imaging, Nuclear Magnetic Resonance spectroscopy, protein structure calculations and advanced molecular dynamics simulation to unveil a stable pre-structuration of coiled-coil dimers as tunable nanodomain-targeting units, containing a tunable fuzzy coat and a bar code-like positive surface charge before membrane association. These protein characteristics and the differences in structures and dynamics between C-terminal lipid anchors of the remorin groups provide a selective platform for phospholipid binding when encountering the membrane surface. Our data suggest that remorins fold in the cytosol with the N-terminal disordered region as a fuzzy structural ensemble around a dimeric anti-parallel coiled-coil core containing a symmetric interface motif reminiscent of a hydrophobic Leucine zipper. The charge distribution, the intrinsic curvature in dimeric coiled-coil remorins, and their domain geometry would confer distinctive membrane association profiles. The lipid-binding of the C-terminal creates avidity through multivalent electrostatic interactions between anionic lipid headgroups and the positively charged dimer surface suggesting a clip-and-divide mechanism to selectively segregate lipid-protein nanodomains.
