Graphical Abstract

Figure 1 shows the flow of the preparation of samples. For wet milling method, distilled water is added about 40 ml then undergo

milling process, while for dry milling method the mixture of the raw materials undergo milling process without distilled water. The

dry milling method is a proper method to obtain fine and homogeneous glass powder (Sarrigani and Amiri, 2019).

Abstract

Ceramic sintered pellets with a chemical composition of 96 mol% ZnO-2 mol% CoO-2 mol% SLS glass were prepared using solid

state method at different milling method i.e wet and dry milling. Milling is one of the processes in the preparation of powder

mixture. The purpose of this study was to find the effect of milling methods which produce the best homogeneity mixture and relate

to the electrical properties of the samples prepared. A comparison in the microstructural and electrical properties of the samples

obtained by both milling methods was made. The best results on these characteristics were achieved through the dry milling

methods at 2 mol% SLS glass concentration, obtaining a nonlinear coefficient of 6.973 and a breakdown voltage 261.139 V/cm.

The samples synthesized by this technique show not only high density value, 96.11% of the theoretical density, but also a

homogeneous microstructure, which compete with those obtained by the wet milling methods.

Graphical Abstract

Figure shows the prominent emission peak is found at 615 nm with the electronic transitions 5D0→7F2. At 615 nm, the strong

emission peak of Eu3+ ZnO/Zn2SiO4 which is characteristically red emission was attributed to magnetic dipole (MD) transitions.

This peak shows that the Eu3+ ions had occupied the non-centrosymmetric site in the Zn2SiO4 crystal lattice. Rare earth elements

share many similar properties and these elements can be identified by 4f orbital that is partially filled with electrons which is, f–f

transitions of electrons can bring to the light absorption so that the spectral characteristics will changed. In addition, the electronic

energy levels of rare earth element are extremely different contrast to other elements. This is due to their ability to absorb or emit

the electromagnetic wave of various wavelengths. As example, Eu2+ ions show an emission accompanied by a transition of electrons

from the 4f6 5d1 excited-state to the 4f7 ground-state. In this work, for the Zn2SiO4 host crystal, Eu3+ ions emit red (> 610 nm)

regardless of the type of host crystals, since the emission derives from a transition of the 4f6 electrons in the 4f inner shell. Using

Eu3+ as a doping candidate will exhibit red-emission of 610-615 nm in Zn2SiO4 host crystals. The increasing of Eu3+ concentration causes an increase in emission intensity until the doping concentration reaches x = 10 mol.%. Besides, the increase in Eu3+ doping

concentration also causes the dominant peak of the emission spectra to shift from higher wavelength to lower wavelength (605 nm

to 615 nm) which can be well explained by the Zn-O-Si expansion lattice phenomenon.

Abstract

New Eu3+ doped Zn2SiO4/ZnO phosphor-based composites were successfully prepared using a simple thermal treatment method.

The influence of Eu3+ content on the morphological and photoluminescence performance of the obtained sample was examined

using XRD, FTIR, FESEM, UV-Vis, and PL measurement. The existence of two crystal phases by the XRD measurement

confirmed the formation of zincite (ZnO) and zinc silicate (Zn2SiO4) crystal phases. The progress of Eu3+ content in the structure

has affected the crystal peaks to become sharper. Besides, the FTIR spectra and FESEM micrograph support the XRD result by

verifying ZnO and Zn2SiO4 phases formation through the existence of their characteristic Zn–O–Si and Zn–O vibration modes with

the decrement of SiO4 broad absorption band as the Eu3+ concentration increased. Also, UV-vis absorption spectra presented by

the composite samples displayed a broad absorbance that confirmed the addition of Eu3+ ions in the ZnO/Zn2SiO4 has caused the

absorption edge of the curve having red-shift. Furthermore, the composites showed broadening emissions in a visible range as a

result of PL from both ZnO and Zn2SiO4 crystal phases. The photoluminescence spectrum showed red shift light emissions at 485

and 615 nm, associating with the Zn2SiO4 crystal phase, in addition to the ZnO crystal phase. From the interesting results achieved,

this ZnO/Zn2SiO4 phosphor-based composites material can be a potent candidate in optoelectronic applications.

Graphical Abstract

Referring to Figure 1, the XRD measurement at 27˚C showed that the atomic structure in the glass sample was amorphous in

nature, where the arrangement of atoms in the precursor glass sample was unstructured and randomly organized. However, the

amorphous structure of the precursor glass changed when it was subjected to the heat-treatment process. Figure 1 displays the

XRD pattern of the glass and glass-ceramic sample against heat-treatment temperature. When the glass sample was treated at

600˚C, the arrangement of atoms in the glass structure remained unorganized. The structure change started to take place when the

heat-treatment temperature was increased to 700˚C. At 700˚C, several diffraction peaks started to appear, indicating the formation

of zinc silicate crystals.

Figure 1: X-ray diffraction (XRD) pattern of 55ZnO–5B2O3–40SLS glass and glass-ceramic sintered at

various temperatures.

Abstract

A new transparent zinc silicate glass-ceramic was derived from the 55ZnO–5B2O3–40SLS glass system via a controlled heat-

treatment method. The precursor glass sample was placed through the heat-treatment process at different temperatures to study

the progress in phase transformation, optical performance and emission intensity of the zinc silicate glass-ceramics. For this

project, material characterization was measured through several tests using densimeter and linear shrinkage measurement, X-ray

diffraction (XRD), Fourier transform infrared reflection (FTIR), ultraviolet–visible (UV–Vis) and photoluminescence (PL)

spectroscopy. The density and linear shrinkage measurements show that the density of the particular glass-ceramic samples

increases with the progression of heating temperature. The XRD analysis display the result in which the zinc silicate crystal starts

to grow after the sample was treated at 700˚C. In addition, the FTIR spectra indicated that the crystallization of the zinc silicate

phase occurred with the appearance of SiO4, ZnO4 and Si-O-Zn bands. UV–visible exhibited the small changes when the value

for the optical band gap decreased from 3.867 to 3.423 eV, influenced by the temperature applied to the sample. Furthermore, the

PL spectroscopy showed an enhancement of broad green emission at 534 nm upon the increased heat-treatment temperature. Thus,

it can be concluded there is the progression of crystal growth as the heat-treatment temperature increased; three emission peaks

appeared at 529, 570 and 682 nm for the green, yellow and red emissions, respectively.

Graphical Abstract

It can be observed that the pore’s size, the thickness of the pore’s walls, and pore’s distribution varied in different sintering

temperatures. The highest total porosity can be observed at 800°C, where the pore’s diameter is the bigger with thinner pore’s walls

and well distributed. While the smaller pore’s diameter with a lack of porous distribution which leads to very low total porosity

can be seen at the image of 700°C.

Abstract

Foam glass-ceramics derived from waste materials can be a low cost alternative and sustainable solution for construction industry.

Therefore, foam glass-ceramics produced from soda lime silica (SLS) glass bottles and clamshell (CS) were produced to investigate

its physical, structural and mechanical properties. This study used 3wt% of CS contents where the prepared powder was compacted

into pellet form prior to sinter at 700-900°C for 1 hour. The minimum density (2.43g/cm3) with maximum expansion (83.98%) was

obtained at 800℃ sintering temperature. The XRD measurement show the wollastonite (CaSiO3) crystalline phase has formed at

800℃ and its crystallinity were increase at a higher sintering temperature. The highest value of mechanical strength (1.21 MPa)

with acceptable high total porosity value (58.27%) was obtained at 900℃ sintering temperature indicates that the fabricated foam

glass-ceramics have potential for building materials. FESEM micrograph has visualize the porous structure of foam glass-ceramics

samples at 800℃ sintering temperature has the largest porous structure with closed pore characteristic. Keywords: Foam glass-ceramics, compressive strength, clamshell, glass, porosity, waste

Figure 1: The compressive strength of GIC on different ageing times and sintering temperatures.

Abstract

In this research, GIC had been fabricated from Alumino-silicate-fluoride (ASF) based glass ceramics derived from waste material

of CS and SLS glass. The ASF based glass ceramics were synthesized by using conventional melt quenching technique and

controlled sintering process of 600 and 800 °C. The GIC sample were analyzed at 7, 14, 21 and 28 days of ageing time. The

properties of ASF glass ceramics and GIC had been determined by using x-ray diffraction (XRD), fourier transform infrared

spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive x-ray (EDX) and compressive

strength (Cs). The XRD analysis revealed Ca5(PO4)3F (fluorapatite) as a major phase in the GIC sample. Next, FTIR revealed a

presence of CO3 group, Si−O−Si, P−O, crystalline phosphate, CH3 and O−H band which indicates structure of glass matrix and

crystallization of GIC sample. The uniform spherical microstructure was observed in FESEM as a result of glass crystallization.

The EDX analysis revealed Ca/P ratio obtained around 2.14-3.36 is suitable for body implantation. The compressive strength

obtained in the range of 17.3-82.03 MPa. Basically, the minimum compressive strength value for glass ionomer (luting cements)

following to International Organization for Standardization (ISO 9917) is 70 MPa. The GIC becomes a potential candidate for

clinical application in dentistry due to excellent adhesion and good biocompatibility towards biological system.

Abstract

In single-band model, the transitions of the charge carriers are observed between the lowest unoccupied molecular orbital (LUMO)

of the conduction band and the highest occupied molecular orbital (HOMO) of the valence band. In this paper, a mathematical

approach in estimating the transition energy of type-II core-shell quantum dots (CSQDs) is analysed in both strong and weak

confinement cases. It is shown that the transition energy in strong confinement would increase by 50% compared to 20% in the

weak confinement case, for which the charge carriers under weak confinement can be inferred as pseudo type-II CSQDs.

Graphene/germanene superlattice is made by stacking together graphene monolayer and germanene monolayer vertically.

Figure 1: Side view of graphene/germanene superlattice

Abstract

We study the structural and electronic properties of graphene/germanene superlattice using density functional theory. Here, we find

that the graphene and germanene are bound together mainly by weak van der Waal forces in the superlattice. This is supported by

small interlayer binding energy of graphene/germanene superlattice. The most stable superlattice stacking is the top stacking

configuration followed by bridge and hollow. In the superlattice, the Dirac cone characteristics of both graphene and germanene

layers is well preserved. The band gap opening at K-point is found due to the unsaturated pz-orbital of germanene layer.

Abstract

Yttrium-substituted bismuth ferrites (BiFe1-xYxO3 (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5)) ceramics were successfully synthesized via

modified thermal treatment method. The effects of Y-substituted BFO on the structural, morphological, magnetic and microwave

absorption properties were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM),

vibrating sample magnetometer (VSM) and professional network analyzer (PNA). The XRD analysis showed the BFO sample was

matched to hexagonal structure which belongs to the R3c space group. The Y-substituted BFO showed phase transformation from

hexagonal to orthorhombic. Pure BFO gives the highest value of grain size of 354 nm. From FESEM analysis, the grain size of Y-

substituted BFO samples decreased as the amount of Y-substitution increased. The grain size ranges from 90 nm to 354 nm. From

VSM measurements, the BFYO sample at x=0.2 gives the highest saturation magnetization (Ms = 3.9494 emu/g) and remnant

magnetization (Mr = 1.2115 emu/g) value. The microwave absorption properties of all samples with 1 mm thickness and at the

frequency range of 8-12 GHz (X-band) are influenced by the amount of Y-substitution in BFO. Pure BFO gives the minimum value

of reflection loss (RLmin) less than -5 dB whilst the Y-substituted BFO caused the RLmin of all samples more than -3 dB compared

to the pure sample. The dielectric properties of Y-substituted BFO caused the dielectric constant (ε′) and loss factor (ε″) to decrease

with frequency for all the samples.

Graphical Abstract

This work reports the physical properties of bulk and nano-sized NSMO. They are excellent with colossal magnetoresistance by

tunable grain size via different preparation methods.

Figure 1: Physical properties and potential applications of NSMO.

Abstract

Colossal magnetoresistive (CMR) manganites have attracted great research interest and studied extensively since its discovery.

However, the work of the neodymium-based system is limited and less attention has been paid to Nd0.7Sr0.3MnO3 (NSMO). This

work reports the NSMO prepared by solid-state reaction and sol-gel method to obtain the manganites with different particle sizes.

NSMO size variation could influence significantly on the magnetic and magneto-transport properties. More interestingly, nano-

sized manganites display unusual physical properties compared to its bulk counterparts. Bulk and nano-sized NSMO crystallised

into the orthorhombic crystal structure and have a strong orientation towards (121) plane. The peak broadening can be observed in

nano-sized NSMO indicates it has the smaller crystallite size. The average grain sizes for bulk and nano-sized NSMO are ~ 607 nm

and ~ 26 nm respectively as revealed from the field emission scanning electron microscope. The AC susceptibility results showed

that Curie temperature (TC) decreases as the grain size decreases. This behaviour can be attributed to the loss of long-range

ferromagnetic ordering in nano-sized grains. The strong suppression of the TMI has been observed as the particle size goes down.

NSMO has recorded the magnetoresistance of 27.7 % near the TMI, which attributed to the increase of disordered magnetic spin

fluctuations in the high-temperature range. This work revealed that the physical properties of NSMO can be modified by the particle

size. Therefore, the tunable grain size behaviour of NSMO by different preparations are highly feasible to be applied in the high-

performance magnetic field sensor. 1-3

Abstract

In this work, magnesium diboride, MgB2 samples were prepared by using magnesium, Mg powder and carbon-encapsulated boron,

B powder (1.35 wt.% carbon) with addition of dysprosium oxide, Dy2O3 and lanthanum oxide, La2O3 as dopants. Different weight

percentages with the ratio of x wt.% Dy2O3: x wt.% La2O3 were used where x = 0.00, 0.25, 0.50, 0.75, 1.00, respectively. X-ray

diffraction (XRD) results indicated MgB2 as the major phase for all the samples. Magnetization measurement showed a slight

decrease of critical temperature, Tc from 38.1 K to 37.6 K with the co-addition of Dy2O3 and La2O3. Self-field critical current

density, Jc at 20 K increased with the increasing of co-addition levels probably due to improved grain coupling. The highest self-

field Jc obtained is 433 kA.cm-2 with 1.00 wt.% co-addition level. Field dependent Jc ( 4 T) at 20 K of the co-added samples is

higher compared to that of the pure one. The present results show that a small amount of Dy2O3 and La2O3 co-addition into MgB2

is effective to enhance flux pinning and Jc.

Abstract

High temperature superconductor (Tl0.85Cr0.15)Sr2CaCu2O7-δ (Tl-1212) with addition of zinc ferrite (ZnFe2O4) nanoparticles were

synthesized using high purity oxide powders through a solid state reaction method. ZnFe2O4 nanoparticles with composition of

0.01 wt.%, 0.02 wt.%, 0.05 wt.%, 0.10 wt.%, and 0.15 wt.% were added to the Tl-1212 superconductor. These Tl-1212 samples

were characterized using scanning electron microscopy (SEM), powder X-ray diffraction method (XRD), energy dispersive X-

Ray analysis (EDX), electrical resistance measurement, and transport critical current density measurement. All samples

indicated Tl-1212 phase of a tetragonal structure with a secondary phase/impurity of CSCO. The transition temperatures (Tc-zero

and Tc-onset) were measured using a four-point probe method. The highest Tc-zero recorded was 97 K, which was exhibited by the

pure Tl-1212 sample. The onset critical temperature (Tc-onset) recorded was between 97 K and 105 K. The transport critical

current, Ic, all samples were found through the 1 µV/cm criterion with temperature ranging from 30 K to 77 K. The introduction

of ZnFe2O4 nanoparticles has enhanced T1-1212 superconductor’s flux pinning effects and increased its transport critical current

density (Jc). Keywords: High temperature superconductor Tl-1212; transport critical current density; ZnFe2O4 nanoparticles

ABSTRACT

Superconductor is an element or compound that conduct current without any resistance below a certain temperature. Yttrium

Barium Copper Oxide (YBa2Cu3O7-∂) was the first high temperature superconductor (HTS) found in 1986, show it would become

superconductive at temperature warmer than liquid. Nowadays, there are many demands for superconductor in their applications.

However, YBa2Cu3O7-∂ superconductor suffers from low grain conductivity and weak links of the grains, thus resulting in disruption

of superconducting performance. This research was focusing on the effect of microstructure and phase formation of YBa2Cu3O7-∂

adding with marine waste, cephalopod bone. Cephalopod bone contains various types of elements which believe has the potential

as an alternative resource for conductor
