Paper spray ionization was paired with a mechanical-gate ion mobility spectrometer to detect herbicide ions. The ion mobility spectrometer contained a drift tube with stainless steel rings and resistors, a detector, and a mechanical gate. Paper spray ionization used high voltage applied to filter paper wetted with analyte solution to create ions. Blank samples consistently produced two peaks likely from protonated water and methanol clusters. Samples with the herbicide prometon consistently showed three peaks, including one from protonated prometon clusters. Aperture grids were investigated to reduce peak width but lowered signal. Future work will optimize peak resolution and identification.
My Problem Dr. Shriniwas Kashalikar
The document discusses "my problem", which is a struggle within individuals between what is and what should be. This restlessness stems from sensory input not matching feelings of wants and deficiencies. "My problem" is a global issue, as it is difficult to voluntarily blossom into generous, loving, and benevolent qualities. Punishment and force cannot transform individuals, only creating a globally beneficial environment through tolerant policies and considering everyone can help with blossoming. However, even this is not possible through individual efforts alone in a sectarian environment. The only solution discussed is universal practice of remembrance of the divine name.

Hollow-Polyaniline-Sphere-Coated Sensor For Measuring Gas-Phase OH Radicals A...
In advanced oxidation processes, OH radicals play a crucial role in enhancing the removal efficiency of volatile
organic compounds. In this paper, hollow polyaniline (PANI) spheres were coated onto a conducting ceramic
honeycomb substrate to form a PANI sensor for detecting the concentration of OH radicals in the amorphous
phase. The hollow PANI spheres were effectively synthesized through a double-surfactant-layer-assisted
polymerization process by using Fe3O4 nanoparticle as the core template. The PANI shell thickness, morphology
characterizations and specific surface area were controlled by altering the weight of aniline monomers. The
electrical conductivity served as a function of the operating temperature and specific surface area, which is a
characteristic behavior of conductive polymer materials in the atmosphere. At an optimized temperature of
125°C and specific surface area of 1435 m2
/g, the PANI sensor reacted with a high amount of OH radicals
generated from the decomposition of ozone over α–FeOOH nanoparticles. The conductometric response after the
OH radical attack increased exponentially with the concentration of the OH radicals.

- Mesoporous glasses can have their bandgap tuned by manipulating the stress in the glass network through thermal annealing. The stress arises from the mismatch in thermal expansion between the pore walls and pores.
- Higher annealing temperatures increase the stress in a mesoporous (TiO2)1-x(SiO2)x glass, widening its bandgap from 3.74 eV to 4.02 eV.
- This physical method of bandgap tuning could enable applications in photocatalysis by allowing optimization of the material for different light wavelengths without chemical doping.

Il lavoro di questa tesi si propone di studiare il problema delle cavità di niobio su rame, partendo dalla caratterizzazione dettagliata dei film depositati per magnetron sputtering lungo una cavità 1,5GHz per finire studiando l’influenza che l’angolo di deposizione e la porosità hanno sulla degradazione delle proprietà superconduttive. Lo studio è stato condotto in maniera sistematica, effettuando numerose deposizioni su substrati di quarzo e rame, utilizzando i parametri di processo e la procedura standard
(CERN-INFN) per il ricoprimento di cavità 1,5GHz. Sono state utilizzate due diverse
configurazioni di magnetron e tutti i film ottenuti sono stati analizzati dal punto di vista delle proprietà superconduttive (temperatura critica, resistività e resistenza,), strutturali (diffrazione di raggi X) e morfologiche (microscopio a forza atomica). Lo studio ha comportato la deposizione di un numero elevato di campioni (13 serie per un totale di circa

Una delle più importanti applicazioni dei materiali superconduttivi è la realizzazione di cavità acceleratrici per i moderni acceleratori di particelle per la ricerca elementare. Finora l'impiego del niobio massiccio ha regnato incontrastato in questo campo della tecnologia: la fortuna dell'approccio tecnologico basato sul niobio non stà tanto nelle sue buone proprietà superconduttive, ma nel fatto che può essere prodotto con un elevatissimo grado di purezza, difficilmente raggiungibile per composti complessi, e soprattutto può essere lavorato con tradizionali metodi metallurgici per ottenere i più svariati dispositivi.
Il Nb3Sn è una lega intermetallica che presenta proprietà superconduttive molto interessanti per le applicazioni in r.f. e potrebbe essere un ottimo candiato a sostituire il niobio in molte applicazioni.

“I’m still / I’m still / Chaining from the Block”
“An Outlook of the Ongoing and Future Relationship between Blockchain Technologies and Process-aware Information Systems.” Invited talk at the joint workshop on Blockchain for Information Systems (BC4IS) and Blockchain for Trusted Data Sharing (B4TDS), co-located with with the 36th International Conference on Advanced Information Systems Engineering (CAiSE), 3 June 2024, Limassol, Cyprus.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
