This document summarizes research on producing porous and non-porous cellulose membranes from a novel solvent system. Cellulose and cellulose-polysaccharide blends were dissolved and cast into membranes. Both microporous membranes with 200nm pores for cellulose alone and 1000nm pores for blended membranes, as well as non-porous membranes, were produced. Analysis showed the cellulose membrane had a cellulose II crystal structure while the blended membrane was amorphous. The blended membrane also showed improved water absorbency and mechanical properties over pure cellulose membranes.

Experiments were carried out to study, impact angle
at constant velocity on the solid particle erosion behavior of
glass fiber reinforced graphite particles filled in epoxy resin
composites. In this work, the various ratio of graphite particles
in weigh were reinforced in glass fiber epoxy resin composite
laminates were prepared, and then evaluated at different
impact angles from 300 to 900 keeping the erodent impact
velocity as constant. The erodent used is silica sand with the
size varies from 100 – 150 microns of irregular shape. The
results were compared with plain epoxy laminate composites.
We find that erosive wear rates of glass fiber reinforced
graphite particles filled in epoxy resin composites is the lowest.
These graphite particles resists fiber matrix debonding. A
plain epoxy laminate composite without graphite particle filled
shows the highest erosive rate.
Resilient Characteristics of Stone Matrix Asphalt MixesIDES Editor
Stone Matrix Asphalt (SMA) is a gap graded mix,
characterized by high coarse aggregates, high asphalt contents
and polymer or fiber additives as stabilizers. In comparison to
dense graded mixtures SMA has higher proportion of coarse
aggregate, lower proportion of middle size aggregate and
higher proportion of mineral filler. It resists permanent
deformation and has the potential for long term performance
and durability. In the present study, an attempt has been made
to study the resilient properties of mixtures of stone matrix
asphalt made with two types of conventional binders namely
bitumen 80/100 and 60/70, with 0.3% by weight of a non –
conventional natural fiber, namely coconut fiber. The mixes
are subjected to both static and repeated load indirect tensile
strength tests. It is observed that the natural fibres have
propounding effect on the resilient properties of the mixes.

PERFORMANCE COMPARISON OF FLYASH AND WOLLASTONITE MICRO-FIBER IN OBTAINING SE...IAEME Publication
Present study aims to find out the role of flyash and Wollastonite micro-fiber in
obtaining cheap self compacting concrete for pavements. Workability tests (Abrams
flow, V Funnel and J Ring test) have been performed which find out the flow,
passability and segregation resistance of trial mixes. Load transfer efficiency test has
also been performed with successful mixes on a pavement prototype. It was observed,
that both flyash and wollstonite micro-fiber when used alone can’t yield self
compaction, but with microsilica content upto 5% they do so, provided their content is
lesser than 20% each, respectively. Wollastonite reinforced concrete has two times
better load transfer efficiency with respect to normal concrete.
Change in the capability of cellulose fibres to retain water during thermally...Michal Jablonsky
The water retention value (WRV) as a measure of the capability of cellulose fibres to retain water (swelling of fibres) was evaluated during accelerated ageing of acidic wood pulp newspaper containing 20% chemical fibres. It has been found that the WRV considerably decreases with accelerated ageing. Relations between the WRV properties and the mechanical properties of paper have also been evaluated. The characterization of samples by mercury microporosimetry has shown that the cumulative column of the pores increases with the period of ageing. On the other hand, the average radius of the pores, as well as their specific surface, decreases. This supports the process of hornification, which occurs during accelerated ageing of paper, as the small pores get smaller and the larger ones get even larger as a result of shrinkage of fibres. When considering accelerated ageing, hornification of fibres as one of the outcomes of fibre brittleness has to be taken into account.

Effect of stacking sequence and hybridization on the tensile and flexural properties of composite
laminates between basalt, jute and flax with E-glass reinforced epoxy have been investigated experimentally. It
was found that stacking sequence is not highly significant on tensile properties, contrasting with flexural strength
and modulus which were strongly dependent on the hybrid configuration between sandwich-like (SL) and
intercalation (IC) sequences. Specific modulus based on the variation densities of the hybrid laminates was used
to discover the best combination either basalt, jute or flax with E-glass exhibits superior properties concerning
on the strength to weight- ratio. Hence, stacking sequences and material selection are among predominant factors
that influence on mechanical properties and very crucial in designing composite hybrid system to meet the desired
requirements.
Cocrystallization is a promising approach in improving the physicochemical properties of drugs/APIs.

Photoactive Additives for Crosslinking Thin Polymer Films: Inhibition of Dewe...Gregory Carroll
In this report, we describe a versatile photochemical method for cross-linking polymer films and demonstrate that
this method can be used to inhibit thin polymer films from dewetting. A bifunctional photoactive molecule featuring
two benzophenone chromophores capable of abstracting hydrogen atoms from various donors, including C-H groups,
is mixed into PS films. Upon exposure to UV light, the bis-benzophenone molecule cross-links the chains presumably
by hydrogen abstraction followed by radical recombination. Photoinduced cross-linking is characterized by infrared
spectroscopy and gel permeation chromatography. Optical and atomic force microscopy images show that
photocrosslinked polystyrene (PS) thin films resist dewetting when heated above the glass transition temperature or
exposed to solvent vapor. PS films are inhibited from dewetting on both solid and liquid substrates. The effectiveness
of the method to inhibit dewetting is studied as a function of the ratio of cross-linker to macromolecule, duration of
exposure to UV light, film thickness, the driving force for dewetting, and the thermodynamic nature of the substrate.
Developments of nano clay particle reinforced plastics are of growing interest towards the
emergence of new materials which enhance optimal utilization of natural resources and particularly of
renewable resources. The effects of nano clay as filler in Basalt–epoxy composite systems on the
tribological properties have been discussed in this article. Basalt fiber reinforced epoxy (BE) composite
finds widespread application in erosive environment due to its several advantages like high wear
resistance, high strength-to-weight ratio and low cost. Experiments were carried out to study the effects
of impingement angle, particle velocity and filler material on the solid particle erosive wear behavior of
BE composite. The erosive wear is evaluated at different impingement angles from 30° to 90° at three
different velocities of 23, 42, & 60 m/s. The erodent used is silica sand with the size range (150 – 280 µm)
of irregular shape. The result shows semi-ductile behavior with maximum erosion rate at 60°
impingement angle. It is observed that wear rate increases with increasing particle velocity and
decreases with increases of filler percentage. The morphology of the eroded surfaces was examined by
using Scanning electron microscopy (SEM).
Partitioning of Inorganic Contaminants into the Polyamide Active Layers of Th...Jingbo Wang
The partition coefficient of solutes into the polyamide active layer of reverse osmosis (RO) and nanofiltration (NF) membranes is one of the three membrane properties that determine solute permeation. However, no well-established method exists to measure solute partition coefficients into polyamide active layers. Further, the few studies that measured partition coefficients for inorganic salts report values significantly higher than one (~3-8), which is contrary to expectations from Donnan theory and the observed high rejection of salts. As such, we developed a bench-top method to determine solute partition coefficients into the polyamide active layers of RO/NF membranes.

Viscoelastic response of polymeric solids in sliding contactspadmanabhankrishnan4
Abstract: The viscoelastic response of polymeric solids to sliding contact conditions
is observed and analyzed with respect to the sliding speed, material composition,
and geometry. It was discovered that polymeric solids produced their own distinct
viscoelastic signatures that cause resonance at certain sliding speeds which can be
explained with resonance conditions for electromagnetic waves. The observed viscolelastic phenomenon is characterized with respect to the relaxation and recovery
times for rigid polymeric solids. It is confirmatory as a demonstration of proof of
existence of viscoelasticity and self-organization in these materials under sliding contact conditions. Viscoelastic observations are also made on the aged specimens in
sliding contact.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

![Cellulose - Polysaccharide Membranes Cast from a Novel Green Solvent System Eugene F. Douglass 1 , Richard Kotek 1 , Richard Venditti 2 , Joel Pawlak 2 1 Department of Textile Engineering Chemistry & Science, North Carolina State University, Raleigh, NC 27695-8301 2 Department of Forest Biomaterials, North Carolina State University, Raleigh, NC 27695-8005 Introduction: A new solvent system was developed in previous work 1 to make novel fibers and films from cellulose; this study is a natural continuation of that work. Cellulose and cellulose – polysaccharide blends have been dissolved and coagulated to make membranes with this system. Both microporous and nonporous membranes were produced. Raw Materials: Cellulose from acetate-grade wood pulp is used as the prime raw material. The other raw materials dissolved in this system are common biomaterials. One specific blend is shown here. The solvent system involves an amine and a metallic salt combined in a specific optimized ratio. Figure 1 - Non-porous cellulose membranes Figure 2 - Micro-porous cellulose membranes 210 ± 42 nm mean pore sizes Figure 3 - Micro-porous cellulose/polysaccharide membranes 1000 ± 208 nm mean pore sizes Experimental Procedure: The fibrous wood pulp (and the polysaccharide (if desired)) is dissolved in a specific optimized solvent blend (of an amine and metallic salt) at elevated temperature under a nitrogen atmosphere. Membranes are cast using a metal casting bar on PET film on a casting table, and the material is coagulated in a non-solvent to precipitate the membrane. A solvent exchange procedure is then used to extract the solvent and salt to replace with an easily removed non-hydrophilic solvent for drying purposes to retain porous morphology. The materials were then analyzed with tensile tests, SEM, WAXS and water absorbency. Figure 4 - WAXS scans of: a) Raw pressed cellulose pulp b) Cellulose membrane c) Cellulose and polysaccharide blend membrane Summary: Porous and nonporous membranes from cellulose and cellulose blended with another polysaccharide have been produced. These membranes are both strong and flexible. These porous cellulose membranes have pore sizes around 200 nm for cellulose alone versus around 1000 nm for the cellulose blend. The resultant crystal structure for the cellulose membrane is Cellulose II, with an amorphous morphology for the blend. This amorphous nature shows the other added polysaccharide affects the former crystal structure upon swelling & dissolution and is fixed in place with coagulation. The cellulose II structure for the cellulose membrane is consistent with other solution membranes developed with other systems 3 . The water absorbance tests shows that the added polysaccharide improves the water absorbency of the membrane, while improving the tensile strength and failure strain %. ,[object Object],[object Object],[object Object],[object Object],SEM micrographs of Membrane Cross Sections Table 2 - Porous membrane water absorbance tests 24 Hour DI Water Immersion Test, 25º C Table 1 - Tensile test comparison (ASTM D882 5lb, or 250lb cell) 500x 5000x 500x 500x 5000x 5000x Cellulose I Cellulose II Amorphous Analysis of SEM micrographs – Figure 1 is nonporous because when water or methanol alone is used as coagulant and then the membrane is dried, the original porous structure collapses due to strong hydrogen bonding forces pulling the structure together while it shrinks as the swelling solvent blend is removed. The solvent exchange procedure locks the pores in place (for figures 2 & 3), and removes the solvent blend without collapsing the pores. Typical 2 θ angles for Cellulose I are 15,17 and 23 3 . These are present in this data. Typical 2 θ angles for Cellulose II are 12, 20 and 22 3 . Clearly a shift is evident in this data. The peaks have been shifted into one, removed or smeared with a cloud, indicating an amorphous morphology.
