Aging induced morphology changes in silicon-based
anodes
Wednesday, 15 May 2019 21:40 (20 minutes)
Although a silicon-based electrode is a promising candidate as anode in Li-ion batteries, repeated
cycling results in significant morphological changes of the silicon particles leading to formation
of highly porous silicon structures. We applied small-angle neutron scattering (SANS) with selec-
tive contrast matching to provide quantitative insights into the solid-electrolyte-interphase (SEI)
coverage around the silicon particles and filling of the evolving porosity within the electrode.

Scientific Highlights at Thermal Neutron Three-Axes
Spectrometer PUMA
Wednesday, 15 May 2019 21:40 (20 minutes)
PUMA is optimally designed for measuring inelastic neutron scattering which covers a wide en-
ergy and momentum range. Owing to high thermal-neutron flux at FRM-II, PUMA is recognized
as one of the most powerful thermal neutron TAS. This attracts various user community groups
to conduct challenging measurements on PUMA such as magnetic fluctuations in unconventional
superconductors or spin-waves in quantum magnets. Here we present selected research results
mainly acquired on PUMA in recent years.

In-situ characterization at high temperature of VDM
alloy 780 Premium
Wednesday, 15 May 2019 21:40 (20 minutes)
Ni superalloys are used for high T applications that require good mechanical properties. The aim
of reaching higher service T forces the development of new materials. VDM alloy 780 Premium has
been developed for higher service T and this work shows its in-situ structural characterization by
means of XRD and ND. The morphology is studied by SEM and SANS, the solvus T of the different
phases is determined and the structural properties correlated with hardening of the materials.

Neutron Diffraction studies on Lithiation dynamics
of graphite anodes
Wednesday, 15 May 2019 21:40 (20 minutes)
Lithium ion batteries most commonly use graphite as an anode material. Understanding the dy-
namical processes of the lithiation and delithiation play a crucial role in understanding perfor-
mance, degradation of graphite based anodes. Our operando neutron diffraction of LiCoO2/graphite
cells showed the occurrence of inhomogeneously delithiated graphite anodes.Phase coexistence of
multiple stages is followed by relaxation into a single phase or a two phase mixture close to the
mean lithium content.

Materials Science Diffractometer STRESS-SPEC -
Current status, new developments and future plans
Wednesday, 15 May 2019 21:40 (20 minutes)
STRESS-SPEC is the dedicated diffractometer for materials science applications at MLZ. It offers
high thermal neutron flux and is mainly used for fast residual strain and texture (bulk, local or
gradient) measurements. Here we will give an overwie on the current status of the instrument.
As we pioneered the use of robotic sample manipulation at STRESS-SPEC, future improvements of
the position accuracy of this device through a new adaptive control system will be also outlined.

Bambus: a new inelastic neutron multiplexed
analyzer for Panda at MLZ
Wednesday, 15 May 2019 21:40 (20 minutes)
A new multianalyzer Bambus is being constructed at Panda, MLZ. The objective is to construct
broad reciprocal space maps at multiple energy transfers, in order to get insights of broad features
at low energy or study complex dispersion laws. Because this spectrometer is designed as a com-
plementary option to the normal TAS mode, a fast switch between the two setups is foreseen. The
general concept will be presented together with the final design, and the results obtained with two
prototypes.

In addition to the “normal triple axis” mode, PUMA is equipped with the multi-analyzer setup
consisting of 11 arbitrarily configurable analyzer-detector channels suited for kinetic experiments
to realize an entire (Q,E)-scan in a single shot. Moreover, the same setup can be used also for po-
larization experiments to determine the spin flip and the non-spin flip components simultaneously
at the same state of the sample. I will present the current status of PUMA with the multi-analyzer
setup.

The neutron single crystal diffractometer BIODIFF is dedicated to structure determination of pro-
teins. Typical scientific questions address the determination of protonation states of amino acid
side chains, the orientation of water molecules and the characterization of the hydrogen bonding
network between the protein and an inhibitor or substrate. BIODIFF is designed as a monochro-
matic diffractometer and is able to adapt the wavelength to the size of the unit cell of the sample
crystal.

Investigations of magnetic excitations focus on new magnetic materials, quantum magnetism, su-
perconductivity, heavy-fermion or low-dimensional systems, frustrated and multiferroic materi-
als. PANDA, being a high-resolution, high-flux cold TAS spectrometer with a remarkably low
background, successfully contributes with high-level experiments to a broad variety of these sci-
entific topics. We here present a selection of recently published results where PANDA experiments
significantly contributed.

Poly(2-alkyl-2-oxazoline) molecular brushes, featuring PMeOx-b-PBuOx side arms, are investi-
gated in aqueous solution. While hydrophobic PBuOx is attached to the backbone, storing the
anticancer drug, Paclitaxel, the hydrophilic PMeOx is at the periphery, facilitating transport in
water. With small-angle neutron scattering, the structure of the PTX-loaded molecular brushes
with different backbone length was revealed, disclosing the effect of the molecular architecture on
the drug-loading ability.

The neutron imaging beam line ANTARES is located at a cold neutron beam port of FRM II and
offers high sensitivity, high spatial resolution and excellent flexibility for sample environment and
other components. ANTARES provides many advanced options: a double crystal monochromator,
a neutron velocity selector, grating interferometer and an option for imaging with polarized neu-
trons.
We will show the instrument ANTARES as well as typical applications and recently performed
scientific projects.

Multiprobe Imaging using Neutrons in conjunction

Wednesday, 15 May 2019 21:40 (20 minutes)
NECTAR is a superior beam-line with access to fission neutrons for non-destructive inspection of
large and dense objects, where thermal neutrons or X-rays face limitations due to their compar-
atively low penetration. With the production of fission neutrons at the instrument, gamma rays
are inherently produced in the same process.
Here we present the advantages of combining the information gained from neutron imaging in
conjunction with gamma imaging at the NECTAR beam-line.

we investigate the telechelic pentablock terpolymer P(n-BuMA-co-TEGMA)-b-PDMAEMA-b-PEG-
b-PDMAEMA-b-P(n-BuMA-co-TEGMA) in dilute aqueous solution as a function of temperature
and pH using small-angle neutron scattering (SANS), elucidating the core-shell structure and the
conformation of chains in the shell.

Wednesday, 15 May 2019 21:21 (20 minutes)
The MLZ provides a number of different instruments – tailored to different scientific problems –
to scientists from all over the world.
As control-suite NICOS is established, providing a common user interface with scripting capabili-
ties and data collection. The hardware abstraction is mostly implemented in ‘entangle’, a TANGO
device server written in Python, but also EPICS, SECoP, and selected other protocols are in use.
Finally, a PLC interface specification effectively allows PnP of hardware.

Compared to poly(N-isopropylacrylamide) PNIPAM, poly(N-isopropylmethacrylamide) PNIPMAM
shows different behavior, though it has a similar chemical structure, only with additional methyl
groups on the backbone, e.g. a higher transition temperature (43 ℃ instead of 32 ℃). We studied
the temperature-dependent phase behavior of PNIPMAM in D2O using small-angle neutron scat-
tering. Different from PNIPAM, inhomogeneities and physical crosslinks appear in the one-phase
state due to the methyl groups.

Wednesday, 15 May 2019 20:41 (20 minutes)
Using quasi-elastic neutron scattering, we study the pressure-dependent hydration behavior of
an aqueous poly(N-isopropylacrylamide) solution during heating through its cloud point (CP). At
high pressure, the hydration water diffuses more rapidly than at low pressure, which indicates
enhanced hydrophobic hydration. An abrupt dehydration, mainly of the hydrophobic groups, is
observed at the CP at low pressure, whereas both hydrophilic and hydrophobic groups dehydrate
gradually at high pressure.

Pressure-Dependence of the Formation of
Poly(N-isopropyl acrylamide) Mesoglobules above
the Cloud Point
Wednesday, 15 May 2019 20:01 (20 minutes)
Influence of pressure on the formation of mesoglobules of the thermoresponsive polymer poly(N-
isopropyl acrylamide) (PNIPAM) in aqueous solution, when heated above its cloud point is inves-
tigated using very small angle neutron scattering. At a critical pressure, a remarkable increase in
the size of PNIPAM mesoglobules is noted. We presume that the observed increase in the size of
mesoglobules is due to the pressure induced enhancement in hydration and subsequent aggrega-
tion of mesoglobules.
