Poly (3, 4-ethylenedioxythiophene)/manganese oxide coated on porous carbon nanofibers(P-CNFs/PEDOT/MnO2) has been successfully developed as an advanced anode material via
electrospinning, carbonization and electrodeposition. The structural and morphologicalcharacterization of the P-CNFs/PEDOT/MnO2 electrode shows that the crosslinked and roughsurface on P-CNFs could provide enough active sites for Li+ storage while PEDOT nanoparticles
and irregular block shape of MnO2 were randomly oriented on P-CNFs surface, endowing an
extended electron-conducting pathway and buffer the volumetric changes upon cycling ofinsertion/extraction, respectively. Benefiting from the above advantages, the resultant PCNFs/PEDOT/MnO2 electrode displayed enhanced electrochemical performances with highest
discharged capacity (1477.20 mAh/g) and improved cycling stability after 20 cycles. The
inclusion of PEDOT in the electrode was also found to reduce the electrochemical reaction
resistance as it facilitated the electron transfer at the interface of electrode and electrolyte. Thus,
the superior electrochemical features of P-CNFs/PEDOT/MnO2 electrode offer a great potential
to be the most promising candidate anode for LIBs.

Theranostics is a term derived from a combination of the words therapeutics and diagnostics.
In this emerging field of medicine, drugs and/or techniques are uniquely combined tosimultaneously or sequentially diagnose and treat medical conditions. The concept oftheranostics is the combination of both therapeutics and diagnostics in one package forimage-guided therapy and also for defining the treatment outcome at an early stage, forinstance in the treatment of cancer. To address that purpose, various nanomaterials arepromising to employ in these two modalities. Currently, we are initiating to develop
nanotheranostic-related project at our research center using curcumin as a raw material for
quantum dot, aimed for covid 19 therapeutic approach. A great property of curcumin, abioactive compound derived from tropical plant, enabling this material for nanotheranostic

Bioresource conversion has attracted much attention as one of promising platforms to produce
renewable energy and chemicals in the future. Biomass consist of hydrocarbon compounds likefossil fuels, but its chemical compositions are different. Hydrocarbon compounds in biomass havebeen used as intermediate platforms molecules to produce fuels and chemicals. In addition, its
components have been widely applied in fabrication of bio-based materials for energy storage
device and solar energy conversion, such as batteries, supercapacitors, and solar cells.
Photocatalysis is one of the most promising technologies, that uses light with catalysts to convert
various bioresources to high value chemicals and fuels. TiO2 is one of the most important metaloxide photocatalysts, that is used in many photocatalytic applications. It has been reported to benanostructured in various forms, such as nanoparticles, nanorods, nanofilms, nanofibers, etc.
Zero-dimensional nanomaterials have high surface area; while one-dimensional nanostructures,such as nanofibers, nanorods and nanotubes, have great basic properties, such as great electrontransfer, low charge recombination, and easy recycling abilities. In this contribution, zero- andone-dimensional nanostructured TiO2 were fabricated by solution processes. Important parametersof the fabrication processes were optimized to produce TiO2 nanostructures with good properties,
including small crystal phase, high crystallinity, and high surface area. Obtained zero- andone-dimensional TiO2 nanostructures were characterized by scanning electron microscopy (SEM),
transmission electron microscopy (TEM), BET-surface area technique, X-ray diffraction (XRD),
UV-vis spectroscopy, and PL spectroscopy. Obtained TiO2 nanostructures were utilized as
photocatalysts for conversions of lignin, glucose, and water to high value chemicals and fuels (e.g.
hydrogen). The modifications of TiO2 materials were carried out for improvement of the ability ofvisible light absorption and increasing efficiency of catalysts for enhancing high photocatalytic
activity.

ABSTRACT
A labelled free electrochemical immunosensor based Cooper Metal Organic Frameworks wasconstructed for the detection of Hepatitis B surface Antigen (HBsAg), The immobilization of antibody
on electrode surface was successfully achieved using covalent interaction between carboxyl group of
antibody and amino functional ligand in Cu-MOF via EDC/NHS coupling. The optimum amount of
PVP and TEA successfully resulting nanosphere structure of Cu-MOF and displayed excellent
electrocatalytic activity toward the analyte probe. The Cu-MOF nanosphere with amino functional
ligand not only act as nanocarrier for antibody immobilization but also acts as electroactive material
for electrochemical signal reporting. The electrochemical sensing performance was characterized byusing Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), and Differential Pulse
Voltammetry (DPV). The obtained current response proportionally decreases with the increase of
HBsAg concentration, thus the quantitively HBsAg detection can easily achieved. This strategy
successfully resulting wide linear range detection of HBsAg from 1 ng/ml to 500 ng/ml within Limit ofDetection of 1 ng/ml. This approach is low cost, simple, and potentially to be applied in clinical analysis.

Quaternary ammonium ion is one of the cations used in preparing ionic liquids, which
commonly constructed from petrochemical products. Due to the resource depletion issue andthe intense usage of QAS in various application, we explored the functionality of renewablematerials which is fatty acid extracted from vegetable oil in synthesising bio-based quaternaryammonium salt (QAS). Lauric acid which is the major fatty acid component in coconut andpalm kernel oil s composition was utilized and reacted with tris(3-aminopropyl)amine toobtain fatty amide. The quaternarization step was then proceed to produce QAS by reacting
fatty amide with alkyl halide. The chemical structural and thermal properties of fatty amide
and QAS were characterized using Fourier transform infrared (FTIR), nuclear magnetic
resonance (NMR) spectroscopy and differential scanning calorimetry (DSC). Besides, themeasurement of ionic conductivity was done in order to determine the electrochemical
properties of bio-based QAS. The presence of significant peaks at 3294 cm-1, 1639 cm-1 and
1546 cm-1 representing the peaks for N-H stretching, carbonyl amide stretching, and N-H
bending, respectively from the FTIR analysis proved that fatty amide was successfully
synthesized. The chemical structure of fatty amide and QAS is further confirmed by NMR
spectrum. The DSC thermogram showed that QAS has a few solid-solid transitions whichsuggest to behave as ionic liquid crystal. The ionic conductivity of QAS obtained were
1.83×10-6 S cm-1 at 0
and increased to 8.15×10-5 S cm-1
. The potential bio-based
QAS was further tested as electrolyte in dye-sensitized solar cell (DSSC) application.
Interestingly, it showed a promising performance with the power conversion efficiency of
1.0%.

The release of sulfur dioxide from fuel combustion is now becoming an environmental
and human health concern. To encounter this, hydrodesulfurization (HDS) is implemented to
produce low sulfur fuel oil, however it requires harsh operation conditions and hard to remove
steric sulfur such as dibenzothiophene. Extractive desulfurization (EDS) is one of thealternative processes that have been explored to remove sulfur via extraction. Many researchers
used organic solvent and ionic liquid as extractant in EDS, however it is unfeasible forindustrial application due to the pricy solvent and high toxicity. Therefore, deep eutectic
solvent (DES) was introduced as alternative solvent which is easy to synthesis andenvironmental-friendly. In this work, glycerol, ethylene glycol, tetraethylene glycol andpoly(ethylene glycol) were mixed with tetrabutylammonium chloride to form EDS extractant.
The thermal characterization, extractant formation, viscosity, density and DES performance in
EDS was studied. Thermal analysis study revealed that higher ethoxy chains DES has higher
thermal stability while fourier transformation infrared spectroscopy confirmed the formation of
DES. Moreover, the density and viscosity of DES can be modified by changing the ratio of
glycols. High extraction efficiency can be obtained using longer glycol chain at minimum ratio.
Tetrabutylammonium chloride:poly(ethylene glycol) (1:2) was screened as the promisingsolvent with 93.89% sulfur removal within three extractions cycles. Response surface
methodology was applied to study the sensitivity of operating parameters. Statistical analysis
shows that DES volume was the most significant factor, followed by extraction temperatureand PEG ratio. Removal of DBT can reached as high as 79.01% at 298 K, PEG ratio of 1 and
DES volume ratio of 1. The present findings could provide valuable insight on thedevelopment of pragmatic EDS technology as a substitute to previous HDS process.

DEVELOPMENT OF COVID DETECTION USING SPR SENSORS: A
PRELIMINARY RESULTS
Feraliana, Isa Ansori, Brian Yuliarto, Husna Nugrahapraja
Department of Nanocience and Nanotechnology, Institut Technologi Bandung

ABSTRACT

Coronavirus or SARS-CoV 2 is a virus from the Coronaviridae family that has been epidemic
throughout the world since the end of 2019. The virus spreads ten times faster through humaninteraction than SARS-CoV. RNA sequence of Sars CoV 2 has 79,5% similarity with SARSCoV. A fast and specific detection of SARS-CoV 2 is needed so that patient detection can bedone quickly and accurately. One method that can be developed as a sars cov 2 biosensor isaptamers-based biosensors. Aptamers are artificial oligonucleic acid that can specifically bindto target molecules. Aptamers are easily chemically modifiable for increased stability andreduced toxicity. They show comparable affinity for target virus and better thermal stability
than monoclonal antibodies. Those advantages make aptamers promising candidates indiagnostic and detection applications. The goal of this research was to use RNA aptamer as the
specific recognition element in a portable surface plasmon resonance (SPR) biosensor for
detection of SARS-CoV 2 in human. Aptamer RNA 3 SARS-CoV 2 was designed using the
SARS-CoV 2 sequence from Gisaid using the in silico method. End of aptamer RNA 3
modified with dithiol. Then, the aptamer was immobilized on the gold nanoparticle sensor
surface via Cysteine-dithiol binding. The RNA solution that had been extracted from swab
samples, was diluted ten times before being used as a sample. The immobilized aptamer RNA
3 captured Sars CoV 2 in RNA solution, causing an increase in refraction index (RI). Aptamer
RNA 3 was found to bind RNA virus of Sars CoV 2 where the positive sample of Sars Cov 2
has refraction index (RI) between 10 r.u – 30 r.u. Then the negative sample of Sars Cov 2 has
refraction index (RI) between -5 r.u – 5 r.u.

The electrode materials of fuel cells and batteries are varieties. Look back on time with theanalytical process revealed that some of the materials are still being used and grown until
nowadays as Zinc (Zn), Manganese (Mn), Carbon (C), Nickel (Ni), Platinum (Pt), etc. Why they
have been stilled and What benefit of those metals are questions that what should be focused on
and try to understand about them. Besides, the important thing about that is because thesematerials can change the world in terms of energy technologies. Moreover, each decade shows
what innovation happens and how hard the research tries to develop electrical storage and/or to
produce the direct current for a good living choice and shift the society forward to the smart
things in the civilized city.

E-mail: mohd.yusri@ukm.edu.myIn this work, nickel-palladium (NiPd) alloy-reduced graphene oxide (rGO) composite has
been prepared via liquid-phase deposition (LPD) technique and applied as counter electrode (CE)of dye-sensitized solar cell (DSSC). The effect of Ni content on the properties of the composite
and the performance of the device utilizing the composite CE has been investigated. The
morphology of the composite is described by rumples and white strips distributed on the ITO
surface. The device utilizing the CE prepared with the Ni:Pd ratio of 20:1 owns the highest power
conversion efficiency ( ) of 2.13%. This is due to this device possesses the lowest series
resistance (Rs) of 84.6

and the highest incident photon conversion efficiency (IPCE) of 11.5%.

The findings of this work reveal that NiPd-rGO composite has potential to substitute platinum(Pt) as CE of DSSC since its is comparable to that of Pt based device.
