Surface Passivation Schemes for High-Efficiency c-Si Solar Cells - A Review
Balaji, Nagarajan,Hussain, Shahzada Qamar,Park, Cheolmin,Raja, Jayapal,Yi, Junsin,Jeyakumar, R. The Korean Institute of Electrical and Electronic 2015 Transactions on Electrical and Electronic Material Vol.16 No.5
To reduce the cost of solar electricity, the crystalline-silicon (c-Si) photovoltaic industry is moving toward the use of thinner wafers (100 μm to 200 μm) to achieve a high efficiency. In this field, it is imperative to achieve an effective passivation method to reduce the electronic losses at the c-Si interface. In this article, we review the most promising surface passivation schemes that are available for high-efficiency solar cells.
Sputtering Deposition of Aluminium Molybdenum Alloy Thin Film Anodes for Thin Film Microbatteries
Balaji Sivaramakrishnan,Mani Chandran Thirumoolam,Mutharasu Devarajan 대한금속·재료학회 2015 ELECTRONIC MATERIALS LETTERS Vol.11 No.3
Al5Mo thin film anodes for Li-ion batteries were prepared using DC sputtering under different conditions, the latter being specified as deposition at room temperature (S0), deposition at 300°C (S1), and deposition at room temperature followed by thermal annealing at 300°C (S2). The thin films were deposited using an aluminum target tiled with molybdenum discs at a ratio calculated based on the theoretical sputtering yields. The structural and compositional analyses performed with x-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDX) confirmed the Al5Mo compound formation and the Al/Mo elemental ratio, respectively. The compound formation was observed to be evident only for the thin films subjected to heat treatment during or after deposition. Scanning electron micrographs reveal a higher porosity of approximately 23% for sample S0 and a lower porosity of around 18% for sample S1. The chronopotentiometry results show a higher volumetric specific capacity of approximately 197 mAh/cm3 for sample S1. Capacity increments have been observed for all samples upon charge-discharge cycles, whose values after 25 cycles for samples S0, S1, and S2 were 41.2%, 20.4%, and 21.1%, respectively.
Extended lymphadenectomy in locally advanced rectal cancers: a systematic review
Balaji Mahendran,Supriya Balasubramanya,Simone Sebastiani,Sebastian Smolarek 대한대장항문학회 2022 Annals of Coloproctolgy Vol.38 No.1
Purpose: The surgical treatment of advanced low rectal cancer remains controversial. Extended lymphadenectomy (EL) is the preferred option in the East, especially in Japan, while neoadjuvant radiotherapy is the treatment of choice in the West. This review was undertaken to review available evidence supporting each of the therapies. Methods: All studies looking at EL were included in this review. A comprehensive search was conducted as per PRISMA guidelines. Primary outcome was defined as 5-year overall survival, with secondary outcomes including 3-year overall survival, 3- and 5-year disease-free survival, length of operation, and number of complications. Results: Thirty-one studies met the inclusion criteria. There was no significant publication bias. There was statistically significant difference in 5-year survival for patient who underwent EL (odds ratio, 1.34; 95 confidence interval, 0.09–0.5; P=0.006). There were no differences noted in secondary outcomes except for length of the operations. Conclusion: There is evidence supporting EL in rectal cancer; however, it is difficult to interpret and not easily transferable to a Western population. Further research is necessary on this important topic.

The electrochemical determination of semicarbazide (SCB) executed by using cobalt oxide (Co3O4)nanoparticle modified electrode which was fabricated by using simple precipitation method. The assynthesizednanoparticles have been well characterised by X-ray diffraction (XRD), Furrier transforminfra-red (FTIR), UV-visible (UV-Vis) spectroscopic techniques, energy dispersive analysis of X-ray(EDAX), BET surface area, thermogravimetric (TG) analysis and transmission electron microscopic (TEM)techniques. The XRD shows face centred cubic (FCC) structure, the FTIR demonstrated a major bandsappeared at 574 cm 1 and 669 cm 1 are suggesting the (Co-O) vibrational mode of Co3O4. The TEM ofCo3O4 NPs has been confirmed its ultra-small particle size is of2 nm 0.5 nm. Whereas, EDAX showsthe only cobalt and oxygen are available confirms Co3O4 having high BET surface area. The fabricatedCo3O4 acted as a highly sensitive electrochemical sensor for the determination of SCB by using linearSweep voltammetry (LSV), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) in0.5 M KOH solution. Significantly, anodic onset potential observed at 0.2 V vs. SCE, linear range of scanrate and concentration (1 mM–100 mM) with (LOD 0.13 and LOQ 0.46) and high current and potentialstability with pH dependent behaviour confirms Co3O4 based electrocatalytic system is good for oxidativedetermination of SCB. The selectivity of the sensor also tested by using mixture of other environmentalactive species with SCB by using LSV measurements. This proposed system is applicable in food andpharmaceutical industries for the determination of SCB as an amperometric sensor.

Devices with negative differential transconductance (NDT) and negative differential resistance (NDR) have shown a strong potential for digital electronics with high information density due to their N-shaped current–voltage (I–V) characteristics leading to multiple threshold voltages ( Vths). The 2D materials, such as graphene, hBN, MoS2, WS2, etc., offer an attractive platform to achieve NDT and NDR because of the absence of dangling bonds on the surface, leading to a high-quality interface between the layers. The 2D materials' unique property of the weak van der Waals (vdW) interactions without dangling bonds on the heterostructure devices shows the way for the applications more than-Moore devices. This review holds a well-timed overview of 2D materials-based devices to develop future multi-valued logic (MVL) circuits exhibiting high information density. Notably, the recent advances in emerging 2D materials are reviewed to support the directions for future research on MVL applications.
