NMR studies of fluoropolymers and of polyaniline [PDF]

, 1998
This thesis presents a study of two polymers, poly(trifluoroethylene) (PTrFE) and polyaniline (PANi), by means of Nuclear Magnetic Resonance Spectroscopy (NMR).The first part of the thesis focusses on investigations in connection with the fluoro polymer.

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

Advanced Functional Materials, EarlyView.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.

Image-based artificial intelligence for preoperative differentiation of pancreatic cancer from pancreatitis: a systematic review and meta-analysis

Frontiers in Oncology
BackgroundPancreatic cancer (PC) and pancreatitis—encompassing acute, chronic, autoimmune, and other inflammatory pancreatic conditions—often exhibit overlapping clinical and imaging features, yet require fundamentally different therapeutic strategies ...

Effect of different NADH oxidase levels on glucose metabolism by Lactococus lactis : kinetics of intracellular metabolite pools determined by in vivo nuclear magnetic resonance

, 2002
Three isogenic strains of Lactococcus lactis with different levels of H2O-forming NADH oxidase activity were used to study the effect of oxygen on glucose metabolism: the parent strain L.

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...
