Tara Titian Maulidya,Fauzio Nurul Khaira,Febi Ramdhani Rachman,Reynold Harris Malingkas 대한의진균학회 2023 대한의진균학회지 Vol.28 No.2

A connection was reported between hepatitis C virus (HCV) and chronic kidney disease (CKD). A viral infection can be both a cause and a consequence of CKD. HCV infection is associated with a greater incidence of diabetes mellitus and CKD and a higher risk of systemic (particularly cardiovascular) effects because HCV infection increases the chance of illness developing. Although the fundamental symptom of HCV-induced glomerulonephritis has been well documented, the virus has been related to CKD in various ways, i.e., new evidence points to a connection between HCV infection and CKD onset, as well as the rapid advancement of CKD to end-stage renal disease, which calls for kidney transplantation or hemodialysis. An HCV infection dramatically increased a person's risk of developing CKD, which can lead to kidney failure. Compared with patients with HCV infection and existing CKD, those with HCV infection who had normal renal function had greater odds of renal progression. The administration of anti-hepatitis medication can result in variations in the estimated glomerular filtration rate, which can either lead to an improvement or a worsening of the patient's health, depending on which direction the variation goes.

<P><B>Abstract</B></P> <P>Methylammonium lead iodide perovskite solar cells (PSCs) based on a solution-processed ZnO electron transporting layer were systematically investigated at low-temperature operating conditions. The power conversion efficiency gradually improved from 14.2% to 15.5% as the temperature decreased from 298 to 253K, mainly owing to increments of short circuit current density and open circuit voltage. In addition, the improvements in photocurrent related to the high charge carrier mobility, owing to the ideal nondispersive charge transport and fast electron transport lifetime at low temperature. Strikingly, hysteresis was suppressed with decreasing temperature related to the inhibition or relatively slow of ionic migration at reversed poling direction. This finding shows promising result of PSCs working efficiently under low temperature condition.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Under low-temperature operation, the efficiency of perovskite solar cell improved from 14.2% to 15.5%. </LI> <LI> Hysteresis was suppressed with decreasing temperature. </LI> <LI> To reveal the mechanisms underlying the observed improvements, the structural, optical, and electrical properties of the solar cells was characterized. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Ginting, Riski Titian,Kaur, Sandeep,Lim, Dong-Kwon,Kim, Jung-Mu,Lee, Joong Hee,Lee, Seung Hee,Kang, Jae-Wook American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.41

<P>Herein, a novel strategy is presented for enhancing light absorption by incorporating gold nanostars (Au NSs) into. both the active layer of organic solar cells (OSCs) and the rear-contact hole transport layer of perovskite solar cells (PSCs). We demonstrate that the power conversion efficiencies of OSCs and PSCs with embedded, Au NSs are improved by 6 and 14%, respectively. We find that pegylated Au NSs are greatly dispersable in a chlorobenzene solvent, which enabled complete blending of Au NSs with the active layer. The plasmonic contributions and accelerated charge transfer are believed to improve the short-circuit current density and the fill factor. This study demonstrates the roles of plasmonic nanoparticles in the improved optical absorption, where the improvement in OSCs was attributed to surface plasmon resonance (SPR) and in PSCs was attributed to-both SPR and the backscattering effect. Additionally, devices including Au NSs exhibited a better charge separation/transfer, reduced charge recombination rate, and: efficient charge transport. This work provides a comprehensive understanding of the roles of plasmonic Au NS particles in OSCs and PSCs, including an insightful approach for the further development of high-performance optoelectronic devices.</P>

Dual Light Trapping and Water-Repellent Effects of a Flexible-Based Inverse Micro-Cone Array for Organic and Perovskite Solar Cells

Ginting, Riski Titian,Jeon, Eun-Bi,Kim, Jung-Mu,Jin, Won-Yong,Kang, Jae-Wook American Chemical Society 2018 ACS APPLIED MATERIALS & INTERFACES Vol.10 No.37

<P>A simple and cost-effective fabrication process of a flexible-based inverse micro-cone array (i-MCA) structure textured on flexible transparent conductive electrodes (TCEs) was successfully demonstrated via a micro-imprinting process. The flexible i-MCA films exhibited an extremely high total transmittance of ∼93% and a haze of ∼95% with reduced reflectance while simultaneously demonstrating water-repellent properties. Introducing i-MCA on the illuminating side of organic solar cells (OSCs)- and perovskite solar cells-rigid glass substrate showed improved power conversion efficiencies (PCEs) due to the light trapping effect by multiple light bounces between cone array structures (forward scattering). This results in an increase of the optical path length in the photoactive layer. Similarly, flexible TCEs embedded with textured i-MCA increased the PCE by 14% for flexible OSCs. More importantly, i-MCA-TCE-based OSCs were highly flexible with 98% retention from the initial PCE at both 0° and at 60° even after 2000 bending cycles at a radius of 2 mm. This finding demonstrates that textured i-MCA is promising for improving: (a) the light harvesting efficiency of solar cells when installed in low-/high-latitude locations and (b) the wearable technology where a flexible device attached on curved objects could retain the PCE, even at an oblique angle, with respect to the normal incidence angle.</P> [FIG OMISSION]</BR>

A Simple Approach Low-Temperature Solution Process for Preparation of Bismuth-Doped ZnO Nanorods and Its Application in Hybrid Solar Cells

Ginting, Riski Titian,Lee, Hock Beng,Tan, Sin Tee,Tan, Chun Hui,Jumali, Mohd. Hafizuddin Hj.,Yap, Chi Chin,Kang, Jae-Wook,Yahaya, Muhammad American Chemical Society 2016 The Journal of Physical Chemistry Part C Vol.120 No.1

<P>A simple low-temperature solution processed bismuth-doped ZnO nanorods (NRs) and poly(3-hexylthiophene) (P3HT) were used as electron acceptor and donor, respectively, in a hybrid inorganic-organic photovoltaic system. Controlling Bi precursor concentration via solution processing (hydrothermal method) plays an important role in altering the morphology, structure, and intrinsic defects of ZnO NRs. Interstitial doping of BiBi2O3 into ZnO (BiZO) NRs results in simultaneous improvement of the open circuit voltage and short circuit current density primarily due to prolonged charge carrier recombination lifetime, increased donor-acceptor interfacial areas with efficient exciton dissociation, and charge carrier mobility. As a result, the power conversion efficiency of the 2 wt % BiZO NRs-P3HT device was significantly enhanced by 55% compared with that of the pristine device. Overall, our study highlighted the immense potential of BiZO NRs as an excellent electron acceptor for fabrication of hybrid optoelectronic devices.</P>

<P><B>Abstract</B></P> <P>In this study, a simple and cost-effective method of fabricating hybrid transparent conductive electrodes (TCEs) based on embedded silver nanowires (Ag NWs)/PEDOT: PSS was developed with the addition of low-temperature synthesis of Ni(OH)<SUB>2</SUB> and polyethylenimine ethoxylated (PEIE) composites as a novel interlayer. The hybrid TCEs with a Ni(OH)<SUB>2</SUB>-PEIE interlayer exhibit remarkable volumetric capacitance of 443 F cm<SUP>−3</SUP> with transparency of 86%, which is one of the highest values reported to date in the transparent supercapacitor. The fabricated bifunctional solid-state electrochromic-supercapacitor device with a transparency of 80% shows stable cyclic stability up to 10,000 charge/discharge cycles, extremely high coloration efficiency of 517 cm<SUP>2</SUP> C<SUP>−1</SUP> at 633 nm, and a fast switching speed (<0.6 s). The noted improvement is mainly caused by the Ni(OH)<SUB>2</SUB>-PEIE interlayer influence the pore density of PEDOT: PSS which provides high surface area, thus resulting in efficient charge transfer pathways and fast ion diffusion. Moreover, a capacitance retention of 90% is achieved even after 8000 bending cycles at a bending radius of 1 mm and 15 times of crumpling is tolerated without noticeable degradation, implying excellent mechanical robustness and flexibility.

Aina Shasha Hashimi,Riski Titian Ginting,Siew Xian Chin,Kam Sheng Lau,Muhammad Amirul Nazhif Mohd Nohan,Sarani Zakaria,Chi Chin Yap,Chin Hua Chia 한국물리학회 2020 Current Applied Physics Vol.20 No.1

We report the microwave synthesis of copper nanowires (CuNWs) by using alkylamine-mediated approach. The aspect ratio of CuNWs of this study was two–fold compared to the previous microwave-assisted synthesis study. In addition, we showed that microwave synthesis could produce high aspect ratio CuNWs in a much shorter time compared to conventional method. Purification process of CuNWs was done via a simple and fast centrifugation method using water-hydrophobic organic solvent system. We also show the importance of purification process on the performance of the fabricated transparent conductive electrode (TCE) films. Purified CuNWs TCE showed a low sheet resistance of 35 Ω/sq with high transparency of 81% (at λ550 nm). Furthermore, we demonstrated how the retreatment of acetic acid was able to assist CuNWs to regain its high conductivity even after five cycles of repetitive continuous oxidation process.
