text: "Magnetic nanofibers were prepared by electrospinning polymer/metal solutions
of poly(acrylonitrile) (PAN) with magnetite (Fe3O4) nanoparticles. At a mass ratio
of PAN:magnetite of 2:1, the total solid content in the dimethyl sulfoxide (DMSO)
solution was varied between 15 wt.% and 25 wt.%, which represents the limits of
the spinnable range. The results show that the most homogeneous nanofiber mats
were 21 wt.% solid contents. At 15 wt.% solid contents, a nano-membrane with some
fibrous regions was produced. Nanofibers at 25 wt.% had a much larger and more
inhomogeneous diameter. Nevertheless, the magnetic properties of all samples were
very similar, indicating that the distribution of magnetite nanoparticles in the
fibers is comparable in all samples. The results also suggested that the samples
spun from solutions with near-ideal solid contents (19–21 wt.%) contain agglomerations
of the nanoparticles inside the nanofibers.\r\n "

text: " The increasing development and application of wireless
devices and systems that radiate electromagnetic waves makes electromagnetic interference
(EMI) shielding more and more important in everyday life. In practice, rigid EMI
shields are the most commonly used ones. However, for humans or in automotive
and aviation applications, flexible, drapable materials, such as textile fabrics,
can be more effective and useful. Textile fabrics are usually nonconductive and
not magnetic, i.e., they lack the requirements for EMI shielding. However, shielding
properties of textile fabrics can be achieved by blending yarns with fine wires
or coating fibers or by blending complete textile layers with conductive or magnetic
materials. In this paper, shielding textile fabrics and 3D-printed materials,
as references with different conductive (and partly also magnetic) properties,
are examined. The measurements show a high shielding effectiveness of 80 dB given
by densely woven fabrics with a thin metallic coating in the frequency range of
6.5–11 GHz, while large pores in crocheted fabrics significantly reduce the EMI
shielding effectiveness, and other samples did not show shielding at all, suggesting
that a combination of conductivity and the structure of the samples is responsible
for the shielding potential.\r\n "

text: " A first limited approach for the automated production of
crocheted fabrics was introduced in 2019. However, the knowledge on crocheted
fabrics is very scarce and only few technical applications are presented in the
literature. To provide a basis for possible future technical applications, the
general tensile properties of crocheted fabrics are explored, and a promising
application as composite reinforcement is introduced. Due to the early development
state of the crochet machine prototype, conventionally hand-made crocheted fabrics
are studied and the benefit of improving the machine is evaluated. The mechanical
properties of crocheted fabrics depend significantly on the individual crocheter,
but fabrics produced from the same person are sufficiently reproducible for reasonable
investigations. Anisotropic properties with a trend toward higher resisted forces
in course compared to wale direction were identified with crochets constructed
from single crochet (sc) and from half double crochet (hdc) stitches. Furthermore,
a tendency toward higher possible loads at larger elongations was revealed for
crocheted fabrics compared to knitted ones. To the best of our knowledge, for
the first time crocheted aramid fabrics were used in epoxy composites. With a
crocheted reinforcement in a non-cut composite produced by vacuum-assisted hand
lay-up, significantly higher ultimate tensile strength and Young’s modulus were
recorded compared to a knitted one with comparable fracture modes.\r\n "

text: "Nanofiber mats can be electrospun by different techniques, usually subdivided
into needle-based and needleless. The latter allow for producing large-area nanofiber
mats, e.g., with a width of 50 cm and lengths of several meters, if electrospinning
proceeds for several hours, depending on the required thickness. Even spinning
smaller samples, however, raises the question of homogeneity, especially if defined
mechanical properties or a defined thickness is required, e.g., for filtration
purposes. Very often, only the inner parts of such electrospun nanofiber mats
are used to avoid too high variation of the nanofiber mat thickness. For this
study, we used wire-based electrospinning to prepare nanofiber mats with slightly
varying spinning parameters. We report investigations of the thickness and mass
per unit area, measured on different positions of needleless electrospun nanofiber
mats. Martindale abrasion tests on different positions are added as a measure
of the mechanical properties. All nanofiber mats show unexpectedly strong variations
of thickness, mass per unit area, and porosity, as calculated from the apparent
density of the membranes. The thickness especially varied by nearly one order
of magnitude within one sample, while the apparent density, as the most uniform
parameter, still showed variations by more than a factor of two within one sample.
This shows that even for apparently highly homogeneous areas of such nanofiber
mats, variations cannot be neglected for all potential applications.\r\n "

text: " Dye-sensitized solar cells have been under development
for the last three decades but are yet to see the market. This has been attributed
to stability issues of the electrolyte in the cell. Electrolytes can be liquid,
quasi-solid, or solid. Liquid electrolytes were the first to be developed and,
therefore, have been subject to radical revisions in both composition and applicability.
They have shown the best power conversion efficiencies but have poor thermal stability.
Although quasi-solid and solid-state electrolytes were developed to overcome these
stability issues, they too have their limits. The aim of this paper is to explore
the development of liquid electrolytes, outlining the current state of the technology
and considering their potential in the photovoltaic market.\r\n "

text: " In the context of the energy transition to renewables,
the spotlight is on large systems connected to the power grid, but this also offers
room for smaller, more specialized applications. Photovoltaics, in particular,
offer the possibility of the self-sufficient supply of smaller electrical appliances
on smaller scales. The idea of making previously unused surfaces usable is by
no means new, and textiles such as backpacks, tent tarpaulins and other covers
are particularly suitable for this purpose. In order to create a non-toxic and
easily recyclable product, dye-sensitized solar cells (DSSC), which can be manufactured
through electrospinning with a textile feel, are an attractive option here. Therefore,
this paper investigates a needle electrospun nanofiber mat, whose spin solution
contains polyacrylonitrile (PAN) dissolved in dimethyl sulfoxide (DMSO) as well
es TiO2 nanoparticles. In addition to characterization, the nanofiber mat was
dyed in a solution containing anthocyanins to later serve as a front electrode
for a dye-sensitized solar cell. Although of lower efficiency, the DSSC provides
stable results over two months of measurement.\r\n "

text: Long-term stability belongs to the main problems of dye-sensitized solar cells
(DSSCs), impeding their practical application. Especially the usually fluid electrolyte
tends to evaporation, thus drying the cells if they are not perfectly sealed.
While gelling the electrolyte with different polymers often reduces the efficiency,
using a glycerol-based electrolyte was already shown to result in similar or even
improved efficiency. At the same time, drying of the cells was significantly reduced.
Here we report on improving glycerol-based electrolytes further by varying the
iodine-triiodide ratio and the overall concentration in the electrolyte. Long-term
tests with unsealed glass-based DSSCs were performed over more than 1 year, showing
that most of the cells increased efficiency during this time, opposite to cells
with a commercial solvent-based iodine-triiodide electrolyte which completely
dried after 2–3 months.

text: " Keratin is one of the most important protein materials
and can act as a sustainable biopolymer for manifold applications. This paper
reports on a sustainable extraction method for keratin from wool fiber materials.
The use of this extracted keratin for polymer film preparation and preparation
of nano-composite materials by electrospinning is investigated. The preparation
of keratin films is done in combination with the both biopolymers alginate and
pectin. Keratin nanofibers are prepared in combination with the polymer polyacrylonitrile
PAN. A view on antibacterial properties of the prepared films is given. As further
analytic methods, Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetry,
and scanning electron microscopy (SEM) are used. Finally, the preparation of new
keratin containing materials is described, which may be used in future for biomedical
applications.\r\n "

text: " In times of climate change and dwindling fossil resources,
the need for sustainable renewable energy technologies gains importance, increasingly
fast. However, the state of the art technologies are energy intensive in their
production, like monocrystalline photovoltaic, or even consist of not recyclable
composite material, in the case of wind turbine blades. Despite a lack in efficiency
and stability, dye sensitized solar cells (DSSC) have a high potential to supplement
the state of the art green energy technology in future. With low production costs
and no necessity for toxic compounds DSSCs are a potential product, which could
circulate in the loops of a circular economy. Therefore, with this paper, we provide
the status of research on DSSC recycling and an outlook on how recycling streams
could be realized in the future for glass-based DSSCs without toxic components.
The overview includes work on using recycled material to build DSSCs and extending
the life of a DSSC, e.g., through rehydration. We also illustrate the state of
sustainability research for DSSCs using the VOSviewer tool. To date, the term
sustainability appears in 35 of 24,441 publications on DSSCs. In view of the global
challenges, sustainability should be researched more seriously because it is as
important as the efficiency and stability of DSSCs.\r\n "

text: " The electrolyte for dye-sensitized solar cells (DSSCs)
is subject of constant innovation, as the problems of leakage and drying greatly
reduce the long-term stability of a device. One possible way to solve these problems
is the use of gel polymer electrolytes (GPEs) with a gelling structure, which
offer different advantages based on the used polymers. Here, potential GPE systems
based on dimethyl sulfoxide (DMSO) as solvent for low-cost, non-toxic and environmentally
friendly DSSCs were investigated comparatively. In order to observe a potential
improvement in long-term stability, the efficiencies of DSSCs with different GPEs,
consisting of polyacrylonitrile (PAN), acrylonitrile-butadiene-styrene (ABS),
polyvinyl alcohol (PVA) and poly (vinylidene fluoride) (PVDF) and their blends
with poly (ethylene oxide) (PEO), were investigated over a period of 120 days.
The results indicate that blending the polymers with PEO achieves better results
concerning long-term stability and overall efficiency. Especially the mixtures
with PAN and PVDF show only slight signs of deterioration after 120 days of measurement.\r\n

text: " Alongside efficiency, long-term stability of dye-sensitized
solar cells (DSSCs) is a key factor regarding their commercialization. One suitable
and cost-effective method to increase the long-term stability is to prevent leakage
and evaporation of the electrolyte by gelling it with polymers such as poly(ethylene
oxide) (PEO) and gaining a gel polymer electrolyte (GPE). In this study, a GPE
based on PEO and glycerol is investigated for the first time as electrolyte for
environmentally friendly DSSCs with natural dyes. To evaluate the novel glycerol/PEO
GPE, the ionic conductivity and resulting efficiency progressions of DSSCs were
measured for 75 days. Different molecular weights (MWs) of PEO and blending with
poly(vinylidene fluoride) (PVDF) had negligible impact on efficiencies. 17 wt%
PEO was found to be more suitable than lower concentrations and resulted in a
relatively high efficiency over 75 days. A glycerol electrolyte without PEO had
higher ionic conductivity and achieved higher efficiencies as well but leaked
from the unsealed DSSCs. In addition, the reproducibility was examined especially,
which appeared to be reduced by considerable differences between identical DSSCs
and between measurements of the same DSSC at different times. This emphasizes
the relevance of studying multiple DSSC per sample to ensure reliable results.\r\n

text: " To overcome the long-term stability problems of dye-sensitized
solar cells (DSSC) due to solvent evaporation and leakage, gelling the electrolyte
with polymers is an appropriate option. Especially for future applications of
textile-based DSSCs, which require cost-effective and environmentally friendly
materials, such an improvement of the electrolyte is necessary. Therefore, the
temporal progressions of efficiencies and fill factors of non-toxic glass-based
DSSCs resulting from different gel electrolytes with poly(ethylene oxide) (PEO)
are investigated over 52 days comparatively. Dimethyl sulfoxide (DMSO) proved
to be a suitable non-toxic solvent for the proposed gel electrolyte without ionic
liquids. A PEO concentration of 17.4 wt% resulted in an optimal compromise with
a relatively high efficiency over the entire period. Lower concentrations resulted
in higher efficiencies during the first days but in a poorer long-term stability,
whereas a higher PEO concentration resulted in an overall lower efficiency. Solvent
remaining in the gel electrolyte during application was found advantageous compared
to previous solvent evaporation. In contrast to a commercial liquid electrolyte,
the long-term stability regarding the efficiency was improved successfully with
a similar fill factor and thus equal quality.\r\n "

text: Polyacrylonitrile (PAN) belongs to the group of polymers that are often used
for electrospinning, as it can be applied as a pre-cursor for carbon nanofibers
and is spinnable from the low-toxic solvent dimethyl sulfoxide (DMSO). While the
influence of different spinning parameters on fibre morphology and mass per unit
area was investigated in a previous study, here we report on the impact of the
spinning solution, using DMSO as a solvent and wire-based (needleless) electrospinning.
Our results show that a broad range of solid contents can be applied, providing
the opportunity to tailor the fibre diameter distribution or to optimize the areal
weight of the nanofibrous mat by changing this parameter, while the chemical composition
of the fibres remains identical.
