This paper presents a novel process to fabricate piezoelectric films from polyvinylidene fluoride (PVDF) polymer using integrated fused deposition modeling (FDM) 3D printing and corona poling technique. Corona is one of many effective processes that has received attention activate PVDF as responsive material. The occurs when exposed high electric field created controlled through an electrically charged needle grid electrode under heating environment. FDM seen extensive progress in...
Perfluorooctanoic acid (PFOA) is an artificial chemical of global concern due to its high environmental persistence and potential human health risk. Electrochemical methods are promising technologies for water treatment because they efficient, cheap, scalable. The electrochemical reduction PFOA one the current methodologies. This process leads defluorination carbon chain hydrogenated products. Here, we describe a mechanistic study in gold electrodes. By using linear sweep voltammetry (LSV),...
Abstract This paper presents 3D printing of piezoelectric sensors using BaTiO 3 (BTO) filler in a poly(vinylidene) fluoride (PVDF) matrix through electric situ poling during the process. Several conventional methods require complicated and time‐consuming procedures. Recently developed poling‐assisted additive manufacturing (EPAM) process paves way for filaments by incorporating polarizing processes that include mechanical stretching, heat press, field simultaneously. However, this is limited...
An international workshop identified how pore structures and unique properties that emerge at nano- to sub-nano- size domains can improve the energy efficiency selectivity of electroseparation or electrocatalytic processes for treating water.
Perfluorooctanoic acid (PFOA) has received extensive attention due to its widespread distribution in the environment and concerns of exposure human health. Nano-MgAl2O4 modified carbon nanotubes (CNTs) were synthesized, characterized, used as nanoadsorbents remove ppb (μg/L)-levels PFOA from drinking water brackish groundwater. Nano-MgAl2O4@CNTs composite materials characterized by UV-Vis, FT-IR, DLS, p-XRD, BET, SEM with EDX. The adsorption isotherms kinetic studies fitted a Freundlich...
Electron spin polarization is identified as a promising avenue for enhancing the oxygen evolution reaction (OER), which bottleneck that limits energy efficiency of water-splitting. Here, we report both ferrimagnetic (f-Fe3O4) and superparamagnetic iron oxide (s-Fe3O4) catalysts can exhibit external magnetic field (Hext)-induced OER enhancement, activity proportional to their intrinsic moment. Additionally, chirality-induced selectivity (CISS) effect was utilized in synergy with Hext get...
Reactions of Mo(2)(O(2)CCH(3))(DAniF)(3), DAniF = N,N'-di-p-anisylformamidinate, with oxamidate dianions [ArNC(O)C(O)NAr](2-), Ar C(6)H(5) and p-anisyl, give pairs isomeric compounds where the [Mo(2)] units are bridged by anions. For alpha isomers, C-C unit dianion is nearly perpendicular to Mo-Mo bonds, these essentially each other. beta corresponding bonds parallel Each type isomer stable in solution. The electronic communication as measured DeltaE(1/2) for oxidation Mo(2) significantly...

Abstract Nano-sized hematite (α-Fe 2 O 3 ) is not well suited for magnetic heating via an alternating field (AMF) because it superparamagnetic—at its best, weakly ferromagnetic. However, manipulating the properties of nano-sized (i.e., saturation (Ms), remanence (Mr), and coercivity (Hc)) can make them useful nanomedicine hyperthermia) nanoelectronics data storage). Herein we study effects size, shape, crystallinity on nanoparticles to experimentally determine most crucial variable leading...
