Gold patterns were fabricated on Si wafer substrate via multilayer transfer printing of polyelectrolytes, followed by selective deposition of gold nanoparticles (AuNPs) and then electroless plating of gold. First, PDMS stamp was coated with (PAH)(1)/(PSS/PDAC)(10) multilayer system, followed by transfer printing on the piranha cleaned fresh Si wafer substrate. Next, the substrate was dipped in AuNP solution for deposition of the nanoparticles on PAH layer. Then, the substrate was subjected to electroless plating to obtain the gold patterns. Very clean and precise gold patterns with electrical conductivity of 2.5 × 10(5) Ω(-1) cm(-1) were obtained.

Primary Angiitis of the Central Nervous System and Its Mimics: A Pattern-Based Approach to Biopsies for Central Nervous System Vasculitis.
Arch Pathol Lab Med
March 2025
From the Department of Pathology, University of Michigan, Ann Arbor.
Context.—: Primary angiitis of the central nervous system is a rare vasculitis that affects small parenchymal and leptomeningeal vessels in the brain and spinal cord. As brain biopsy remains the gold standard in diagnosis, the diagnostic approach to brain biopsies for vasculitis is well described.

Background: Pancreatic ductal adenocarcinoma (PDAC) has a high incidence of perineural invasion (PNI), a pathological feature of the cancer invasion of nerves. PNI is associated with a poor prognosis, local recurrence and cancer pain. It has been suggested that interactions between nerves and the tumor microenvironment (TME) play a role in PDAC tumorigenesis.

Finds of stalkless comatulid crinoids in the Southern Hemisphere are extremely rare and are almost exclusively of their centrodorsals. Complete or nearly complete specimens (centrodorsal with articulated arms, cirri and/or pinnules) are known from only a few localities. Here we report a comatulid fossil comprised of a centrodorsal, arms, and pinnules, assigned to Solanocrinitidae gen.

Pharmaceutical pollutants, such as carbamazepine (CBZ), are emerging contaminants that pose significant environmental and health risks due to their persistence in aquatic ecosystems and incomplete removal by conventional wastewater treatments. This study leverages density functional theory (DFT), a gold-standard computational quantum mechanical modeling method, to evaluate the efficacy of SiBN nanoflakes-a novel two-dimensional material-for CBZ adsorption and detection. Our first-principles calculations reveal thermodynamically stable interactions between CBZ and SiBN, with adsorption energies of - 0.

Coastal and Marine Research Centre, Griffith University, Gold Coast campus - G51, QLD 4222, Australia.
Headland bypassing is a mainly wave-driven coastal process that interconnects sediment compartments and allows the continuity of longshore sediment transport. In turn, waves are subject to the variability of atmospheric patterns and climate drivers. This study focuses on identifying the atmospheric systems and associated hydrodynamic conditions that have triggered bypassing pulses in the study area, Fingal Head (New South Wales, Australia), over the last 33 years.
