The growing world population and urbanization have worsened noise pollution, driving the development of sound absorption (SA) research across the globe. This study aims to analyse the SA global research trends and discover the opportunities for future development or collaboration using systematic bibliometric analysis. A total of 2970 articles since 1913 were systematically retrieved. Results reveal that the most productive journal had taken 10.3 % of the total publications. A high correlation r = 0.87 was found between the number of co-authorship and the h-index of a scholar. China has the highest number of publications 55.3 % and most research focused on porous materials. Present findings could be helpful to further develop SA from a global level perspective.

“…In particular, one-, two-, and three-dimensional carbon-based micro/nanomaterials, such as carbon nanotubes, carbon quantum dots, graphene, nanodiamonds, nanofibers, and carbon nanohorns, have been effectively utilized in various biomedical fields due to their significant mechanical, electronic, thermal, optical, and physical properties [ 17 – 19 ]. In addition, carbon materials in electrochemical sensors have been successfully proven to show better sensitivity, higher selectivity, and biocompatibility to identify a wide range of biological and chemical biomolecules [ 20 ]. This research work used carbon material for surface functionalization of an anti-CEA aptamer attachment on a sensor surface and enhanced the electric signal upon binding of CEA with its aptamer.…”

Carcinoembryonic antigen (CEA) is a glycoprotein, one of the common tumor biomarkers, found at low levels in body fluids. Generally, overexpression of CEA is found in various cancers, including ovarian, breast, lung, colorectal, gastric, and pancreatic cancers. Since CEA is an important tumor biomarker, the quantification of CEA is helpful for diagnosing cancer, monitoring tumor progression, and the follow-up treatment. This research develops a highly sensitive sandwich aptasensor for CEA identification on an interdigitated electrode sensor. Carbon-based material was used to attach a higher anti-CEA capture aptamer onto the sensor surface through a chemical linker, and then, CEA was quantified by the aptamer. Furthermore, CEA-spiked serum was tested by using the immobilized aptamer, which was found to not affect the target validation. The limit of detection for CEA in PBS and serum is calculated from a linear regression graph to be 0.5 ng/mL with R2 values of 0.9593 and 0.9657, respectively, over a linear range from 0.5 to 500 ng/mL. This CEA quantification by the aptasensor can help diagnose various surgical tumors and monitor their progression.

“…The semiconductor material is the most important factor that determines the performance of the amplifier circuit [2]. On the one hand, a large number of experts and researchers use silicon and germanium with different doping concentrations to improve the amplifying circuit's ability of perceiving weak signals, while some people use semiconductor materials with different elements to reduce self-noise [3,4]. On the other hand, a lot of theoretical models of bipolar transistor have also been proposed and applied to the internal self-generating capacitance and selfgenerating conductance of semiconductors, including Ebers-Moll model (EM1), EM2, EM3 and Gummel-Poon model (GP) [5].…”

This paper presents a minimum signal model via the AC small-signal model and the uncertainty principle, which reveals the minimum AC signal that can be amplified by a bipolar transistor. The Ebers—Moll model (EM3) can describe the small signal amplification process, but it is difficult to define the minimum amplifiable signal of the bipolar transistor. In this study, the correspondence relationship between the non-equilibrium carrier and the electric injection is proved, and the relationship between the life of the non-equilibrium carrier and the measurable signal is proposed by the uncertainty principle. Next, the limit of perceived minimum voltage is also derived in this paper. Then, combining with EM3 model, the minimum AC signal model of bipolar transistor is presented to calculate the minimum voltage signal of bipolar transistor that can be amplified. Finally, a number of the simulation and experiment results show that when the minimum signal in the model is used as input, the carrier concentration of the bipolar transistor does not change and the base electrode cannot perceive the signal, which verifies the validity of the minimum AC signal model.
