Owing to its prolonged half-life and non-biodegradability, potential accumulation of heavy metals can cause serious health problems. Several cutting-edge diagnostic methods are being utilized for the assay of heavy/toxic metals. Certainly, these methods hold some limitations, such as requirement for extortionate devices and strenuous operations that can only be carried out in laboratories. This led to the emergence of detection methods based on sensors. Among various breakthroughs, paper-based analytical devices as well as paper-based microfluidic devices have turned up as one of the economical, convenient, easily disposable and portable substitutes for on-site detection. This study discusses the current analytical methods and paper-based devices used for heavy metal detection in the first phase followed by the discussion on comparative analysis of various analytical methods. In addition, there are techniques for heavy metal detection, which use substrates like paper, polydimethylsiloxane, etc. using colorimetric, fluorescence or electrochemical sensing, have also been discussed. The development of programmable paper-based microfluidic devices has been emphasized in the second phase of the discussion. Finally, the future progressions and developments in this field have also been proposed.</p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"47 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142524484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A wide range of applications are available that demand a good heat conduction ability. The property used to understand the heat conduction behaviour in a solid is called effective thermal conductivity (<i>K</i><sub>eff</sub>). It is recommended to reinforce an adequate amount of filler material in the matrix to increase the <i>K</i><sub>eff</sub> of the composite. The current study used carbon black (CB) particulates, a by-product of waste tyre pyrolysis, as the reinforcing agent in the epoxy resin. The composites are prepared by solution casting method with different volume % of filler. To study the thermal behaviour of samples, effective thermal conductivity, glass transition temperature (<i>T</i><sub>g</sub>) and co-efficient thermal expansion (CTE) are measured as a function of vol.% of filler. After plotting the experimental results, it is noticed that the <i>K</i><sub>eff</sub> and <i>T</i><sub>g</sub> are increased and CTE is decreased with an increase in vol.% of CB. The percolation threshold is also calculated from the <i>K</i><sub>eff</sub> <i>vs.</i> vol.% curve. Various mathematical models are incorporated to verify the experimental results of effective thermal conductivity. A finite element method (FEM) based numerical model is also developed to study the thermal conductivity behaviour of composites. ANSYS MECHANICIAL APDL is used for the FEM analysis. The FEM results showed a marginal variation from experimental data at 0.99 vol.% of CB. The reason behind this is the formation of voids during sample making, the effect of which is not taken in FEM.</p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"47 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142524344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, different nanostructures of nickel oxide (NiO) and zinc oxide (ZnO) were synthesized using the hydrothermal method by treating the corresponding metal precursors in a high-temperature aqueous solution. The XRD and SEM were used to analyse crystal structure and morphology, respectively. The absorption of ZnO and NiO materials is found to be in the visible range of 300–400 and 200–300 nm, respectively. The band gap of ZnO was calculated as 3.04 eV, while that of NiO was 3.93 eV. The supercapacitor electrode was fabricated on nickel foam with developed nanostructure and carbon materials. The composite ZnO and NiO materials showed an increase in capacitance compared to the bare NiO and ZnO electrodes. This enhancement could be related to improved charge transfer kinetics and increased surface area for electrolyte interaction. Galvanostatic charge–discharge, cyclic voltammetry and electrochemical impedance spectroscopy measurements were conducted to assess the electrochemical efficiency of nanomaterials and their composites. At the current density of 2 A g<sup>−1</sup>, the specific capacitance of the NiO/ZnO composite is found to be 351.54 F g<sup>−1</sup>, which is ~2 times of the bare NiO and ~3.34 times of bare ZnO. The maximum energy density of ZnO nanoparticles, NiO nanoflakes and the composite are found to be 3.96, 6.58 and 13.90 Wh kg<sup>-1</sup>, respectively.
