Self-Organization in Active Soft Matter
Guest Editor(s): Takahiko Ban
It has been an exciting and wonderful journey with Bentham Science Publishers @ Current Physical Chemistry. The editorial team are very much co-operative and at the same time never compromised on the quality aspect of my submission. The unknown reviewers were meticulous with their review. Their comments & suggestions saw to it that my manuscript was presented more authentically.
Over all, I would conclude by saying, “Thank you Bentham- I have had a humbling experience”.

It is a pleasure for me to launch this special issue entitled “Contribution of Mining, Chemical and Metallurgical
Engineering to Science” for Current Physical Chemistry. It is also my honor to become the
Guest Editor again for the special issue of the prestigious Journal Current Physical Chemistry and thanks
to the publisher along with all the reviewers and the Editorial Board Members for their contributions and a
The first study regarding the effect of mechanical activation on the leachability of fayalite in sulfuric
acid solution by Nadirov and Mussapyrova  represents how activation energy requirement is decreasing
after mechanical activation of fayalite that occurs in slag.
The second study of this special issue is on the statistical evaluation of colemanite dissolution conducted
by Ekinci et al. In this study, Taguchi method was used statistically for an orthogonal array consisting of
six factors in five levels for the optimization of dissolution parameters such as reaction temperature, solid-to
liquid ratio, SO2/CO2 gas flow rate, particle size, stirring speed and reaction time .
The third paper by Güler and Polat presents the Effect of MIBC Dosage on the Mitigation of Lizardite
Recovery. Olivine is an important industrial raw material especially for metallurgical applications like
foundry sand, refractory, slag conditioning, etc. Loss on Ignition (LOI) value (>1%) is the main specification
of olivine ore/concentrate for those areas together with chemical specifications. This flotation study
was conducted on natural pH conditions with Na-oleate as a collector to clarify the effect of frother
(MIBC) dosage on the LOI value of olivine concentrate .
In the next study, microwave interaction of magnetite ore concentrate which was mixed with the carbonized
biomass waste and divided into different grain sizes, was studied by Öztürk et al. The study put
forth the effect that how different particle sizes of magnetite concentrate aim at reduction in microwave
oven at the laboratory scale .
The fifth study by the same authors represents mechanical alloying of magnetite concentrate in the
presence of biochar used as a reducer. In this study, biomass waste was used as a source of carbon for the
reduction of magnetite to metallic iron under mechanical conditions. Authors noticed that after 45 minutes
of alloying, the carbonized product milled together with magnetite concentrate was partially integrated
into the crystal structure .
The sixth study gives information regarding a new modeling approach to infrared drying of machine
plaster by Kalender et al. The best model equation was the model based on the Newton drying equation
existing in the previous study. However, the model equation derived by Modified Page has been determined
as the most compatible model with the experimental data .
The next study represents the Characterization of Hybrid Bio-ceramic Hydroxyapatites Reinforced by
Expanded Perlite-TiO2-ZrO2-MgO-P2O5 by Karip and Muratoğlu. In this study, hydroxyapatite, which is
naturally and synthetically available, is often used as a biomaterial because of its similarity to the bone. In
this study, Natural hydroxyapatite powder, synthesized from sheep bone, and synthetic hydroxyapatite
were used as matrix. Hydroxyapatite, calcium silicate, calcium phosphate structures were observed in
XRD analysis. Micro-pores were observed in TiO2-reinforced samples while denser structures were observed
in ZrO2-reinforced samples .
The eighth study included is by Kaya and Özer. In this study, the extraction of oil from Pistacia terebinthus
L’s seeds grown in Elazig-Turkey and called menengiç in the domestic region was investigated.
Effects of the parameters such as extraction time, temperature, seeds/solvent ratio (dosage), the particle
size of seeds and type of solvent were examined on the oil extraction yield. Mathematical model obtained
by solving Fick's second law under the appropriate boundary and initial conditions was used to calculate
diffusion coefficients for the extraction process. Also, the diffusion coefficients calculated for both oily
seeds were nearly equivalent to each other .
In the last study, the estimation of calorific values of some Turkish Lignites by artificial neural network
and multiple regressions was investigated by Özdemir and Sarıcı. Calorific values were estimated by using
artificial neural network and multiple regression model employing lignite data of 30 different regions.
As input parameters, humidity, ash content and volatile matter values were used. In addition, the Mean
Absolute Percentage Error (MAPE) and the significance coefficient (R2) values were determined. MAPE
values were found to be below 10% .
I hope these studies will be useful for researchers.
The advent of nanotechnology has profound influence on the development and applications of new
types of lanthanide materials. Especially in the photonic industry, lanthanide based luminescent materials
play a very important role in several advanced technological applications. Some of their practical applications
include displays, lighting devices, lasers, fiber-optics, security inks and tags, optical sensors, drug
delivery, bioimaging, therapy, photocatalysis, and microscopy. Though there are several other luminescent
materials such as organic dyes and quantum dots utilized for these applications, lanthanide-based materials
deserve special attention due to their important features such as sharp absorption, emission, longer decay
time, photostability, less toxicity, etc. In this context, this special journal volume attempts to explore
some of the recent developments in the photonics and technological applications of rare earth doped materials.
This special issue contains six articles, divided into two volumes. The second volume Vol: 9, No. 3,
2019 contains three articles listed below. Optical properties of Erbium doped hydroxyapatite particle was
reported by Pooja Gitty et al. . Second article by Dr. Kumar is a comprehensive review article on the
spectroscopy of near infrared emitting Nd,Er and Tm with particular emphasis on their applications in telecommunication
and biomedical sensors . Third article by Solange et al.  report the upconversion
spectral properties of hydrothermally synthesized Ytterbium, Erbium and Thulium doped Y2O3.
Lanthanide doped optical materials deserve so much attention in today’s high technology photonics applications
ranging from security authentication to cancer therapy. Trivalent lanthanide ions are considered
to be the most stable and intrinsically, highly efficient light emitters in the vacuum ultraviolet to mid infrared
region. The completely filled outer shell nature of these ions provides a well protective shielding and
thereby the emission and absorption properties are not that much affected by the surrounding crystalline
field which makes them potential candidates for developing high gain optical amplifiers as well as in several
narrow band applications. These ions can be easily incorporated into several crystalline as well as
amorphous materials so as to enable their applications in several diverse fields such as lasers, fiber amplifiers,
solar cells, displays, catalysis, scintillators, and security markers as well as in biomedical areas such
as cancer therapy, bioimaging and other detection and identification purposes. In this context, this special
journal volume attempts to explore some of the recent developments a photonics and technological applications
of rare earth doped materials. This special issue contains six articles and they are divided into two
issues. The first issue (Vol: 9, No. 2, 2019) contains three articles listed below. Biomedical imaging and
therapeutic applications of various lanthanide doped apatites are discussed by authors, Dr. Girija , and
Dr. Meenal . Dr. Kistaiah  reports the spectroscopic studies and energy transfer properties of samarium
doped LLSZFB glasses.
