Applications for effective representation of imaging with X-ray CT
Shizuoka University
CT allows us to observe the 3D voxel internal structure of an object
but the represent method of CT data is still displaying cross sections in 2D images.
Two representing system by AR and VR are proposed, and these systems allow users to observe the
object at any angle intuitively and confirm the cross-sectional image.

Spatial Resolution of X-ray Imaging using 80µm pitch TlBr Detector
1 ANSeeN Inc., Shizuoka University, Tohoku University
TlBr detector is higher resolution than scintillator type detector
because TlBr detector can directly convert X-ray photons into electron-hole pairs.
We create pixelated TlBr detector for high resolution X-ray imaging.
We researched pixelated TlBr detector behavior such as spatial resolution and stability over time.

In vivo measurement of dielectric properties of human skin using attenuated total reflection terahertz time domain spectroscopy
Department of Mechanical Engineering, Shizuoka University, 3
The
applications of terahertz waves have been increasing rapidly in
different fields. With the rapid development of such applications,
encounters between THz waves and humans are expected to become
common. Therefore, it is important to have the knowledge of terahertz
properties of human skin in order to understand the interaction of THz
wave with human skin. In this study, we developed attenuated total
reflection THz time domain spectroscopy and measured the refractive
index and absorption coefficient of skin in the frequency range of
200GHz to 2THz. This information help understand the terahertz wave
interaction with human skin and other possible biomedical application
of THz wave.

The proton beam influence on the sensitivity of wheat plantlets to AgNP pollution - preliminary results
Alexandru Ioan Cuza University, Joint Institute for Nuclear
Research
We highlight that for the experiments involving seed irradiation
(proton irradiation and AgNP supply), we correlate the quantitative results with other studies
from the literature pointing the
influence of two complementary mechanism of action: harmful free radical generation under the
radiation influence as well as surface microorganism annihilation that eventually protected the
embryos, ensuring a better production of pigments after germination and growth.
Further study will consider antioxidant enzyme assay in control and proton beam exposed samples.

Comparison and choice of the greenhouse gas accounting method for a model region in Germany
Institute for the Transformation of the Energy System (ITE),
West Coast University of Applied Sciences, Eco.income engineering GmbH
Following the sustainable development trends, Germany is
steadily moving towards an energy transformation. This complex process
requires serious planning and an interdisciplinary approach. Within the
framework of the German project "WESTKUESTE100" the roadmaps
to complete CO2-neutrality in a model region will be oered. The rst
step in creating realistic scenarios is to analyze existing accounting methods
of greenhouse gas emissions and to adapt the chosen methods for
the specic purposes. This work describes an approach to the selection
and adaptation of the CO2-equivalent emission accounting method for a
model region in order to create scenarios for the energy transformation.

Structure and optical properties of a-C coatings doped with nitrogen and silicon
Francisk Skorina Gomel State University, Belarus
Using a pulsed arc discharge, carbon coatings binary-doped with
silicon
and nitrogen are deposited on quartz and silicon substrates. The structure and phase composition
of
the coatings are studied by atomic force microscopy, Raman spectroscopy, and X-ray photoelectron
spectroscopy. The optic band gap Eg and the refractive index of the coatings are determined
depending
on the alloying elements. The influence of nitrogen and silicon on the formation of the structure
of
the carbon matrix and the formation of chemical compounds in the coatings, leading to a change in
the

Csp2

Enhancing the Seebeck coefficient of Zn-doped MoS2 grown over carbon fabrics via band engineering
Shizuoka University, SRM Institute of Science and Technology
Among various 2D materials, molybdenum disulfide semiconductors have
gained much attention in various applications such as electronics, supercapacitors and
optoelectronics due to their unique transport properties. But the nature of charge transport
remains indefinable as they show lower mobility compared to theoretical values. In the present
work, we report a possible method for enhancing the thermoelectric properties of MoS2 by
effectively growing pristine MoS2 and Zn-doped MoS2 on carbon fabrics (CFs) by a simple
hydrothermal method. The uniform growth of pristine MoS2 and Zn-doped MoS2 on CFs was confirmed by
structural and morphological analysis. Various concentrations of Zn doped MoS2 nanosheets grown on
CFs showed significant enhancement thermoelectric performances. It was found that the electrical
conductivity (1.69 x 102 S/cm) was significantly increased for Sample Zn2 with temperature.

Investigation of the effect of observation window on the sensitivity enhancement in the multi-pass cell outside the expansion wave tube chamber
Shizuoka University
In this study, the sensitivity enhancement of multi-pass cells in the
inclination of the interior cell window was investigated by calculation using the ray-tracing
method considering laser spread and Snell's law to account for window refraction. As a result, the
higher the sensitivity, the smaller the acceptable range of slope. The inclination tolerance of
the observation window is larger than the inclination toler-ance of the concave mirror.

Atomic force spectroscopy experiments with amino-functionalized silicon AFM tips and samples
”Alexandru Ioan Cuza” University
he present work uses plasma technology in combination with
wet-chemistry functionalization methods to functionalize silicon atomic force microscopy (AFM)
probe and sample surfaces with amino (-NH2) chemical groups. Plasma cleaning, oxidation, and
hydroxylation processes are used to chemically activate silicon or silicon nitride surfaces by
generating surface silanol (Si-OH) groups. This process is followed by self assembled monolayer
(SAM) deposition of ethanolamine to generate surface amino groups. The amino-functionalized AFM
probes and samples were used in atomic force spectroscopy measurements that confirmed successful
functionalization by chemical force titration.

Atomic Force Microscopy Indentation of Supported Lipid Bilayers
”Alexandru Ioan Cuza” University
In this work, AFM indentation experiments of supported lipid bilayers
(SLB) on mica are performed to investigate their hardness. In such measurements, the strain
response of the SLB to the compression stress applied by the sharp tip of the AFM probe (curvature
radius of 10 nm) is analyzed. It was observed that under the compression stress, the SLB deformed
first elastically and then plastically (with a lateral disruption of the lipid bilayer).
Transition between elastic and plastic deformation is characterized by the SLB breakthrough force.
It is shown that plasma hydroxylation of the AFM tips decreases slightly the SLB breakthrough
force.
