Abstract:
Forward osmosis (FO) membranes have the advantages of low energy consumption, high water recovery rate, and low membrane pollution trend, and they have been widely studied in many fields. However, the internal concentration polarization (ICP) caused by the accumulation of solutes in the porous support layer will reduce permeation efficiency, which is currently unavoidable. In this paper, we doped Graphene oxide (GO) nanoparticles (50~150 nm) to a polyamide (PA) active layer and/or polysulfone (PSF) support layer, investigating the influence of GO on the morphology and properties of thin-film c

Abstract:
Reduced graphene oxide is a very attractive material for sensor applications. It exhibits high conductivity at room temperature and high specific surface area. Since it can be produced in many ways, its properties can be influenced by the fabrication method. In this paper, we investigated the influence of graphite precursors (flake, scalar and synthetic) on the size of reduced graphene oxide. We have shown that the size of the precursor determines the size of the obtained rGO. We have noted that the larger graphite size, the larger rGO size. Full Text: PDF ReferencesR. Peng, Y. Li, T.

Abstract:
Pristine and doped polyvinylidene fluoride (PVDF) are actively investigated for a broad range of applications in pressure sensing, energy harvesting, transducers, porous membranes, etc. There have been numerous reports on the improved piezoelectric and electric performance of PVDF-doped reduced graphene oxide (rGO) structures. However, the common in situ doping methods have proven to be expensive and less desirable. Furthermore, there is a lack of explicit extraction of the compression mode piezoelectric coefficient (d33) in ex situ rGO doped PVDF composite films prepared using low-cost, solut

Abstract:
The growing popularity and global demand for flexible and wearable microelectronics underscore the need for a cost-effective, eco-friendly, safe, and readily available resource-based clean energy storage system to replace the market-dominating lithium-ion batteries (LIBs)[1],[2]. In particular, concerns about the limited availability and rising costs of lithium resources have heightened the urgency to develop sustainable alternatives. Conventional LIBs, which rely on liquid or gel electrolytes, face significant challenges: corrosion, poor thermal stability, flammability, leakage, and quick den

A multifunctional nano-films of cellulose acetate (CA)/magnesium ortho-vanadate (MOV)/magnesium oxide/graphene oxide wound coverage was fabricated. Through fabrication, different weights of the previously mentioned ingredients were selected to receive a certain morphological appearance. The composition was confirmed by XRD, FTIR, and EDX techniques. SEM micrograph of Mg3(VO4)2/MgO/GO@CA film depicted that there was a porous surface with flattened rounded MgO grains with an average size of 0.31 µm was observed.

Abstract:
Proton exchange membrane fuel cell (PEMFC) has been demonstrated as a highly efficient energy conversion technology. The sluggish oxygen reduction reaction (ORR) at the fuel cell cathode requires 3 to 5 times more catalysts than the hydrogen oxidation reaction at the anode (1). Currently, platinum is still the catalyst material of choice. However, the heavy use of scarce Pt in the electrodes represents a major cost barrier to the commercialization of PEMFCs. Tremendous efforts have been dedicated to reduce or remove Pt usage through the development of Pt-transition metal catalysts, as highligh

Abstract:
It has traditionally been believed that pi-electrons stabilize the D6h structure of benzene. However, this was questioned both using theoretical arguments, as well as circumstantial, experimental evidence. The theoretical arguments have all been based upon the partitioning of the total energy into the sigma- and pi- parts. This partitioning is not unique, the conclusions can be questioned.[1] We suggest an alternative approach based on the forces, calculated using the Hellmann-Feynman theorem. The partitioning of forces into their sigma and pi components is unique and can be used to analyze th
