Deposition of platinum-group metals in sediment and water bodies along the coastal belt of Ghana [PDF]

Maejo International Journal of Science and Technology, 2011
Water and sediment samples from seven water bodies along the coastal belt of Ghana were assessed for the deposition of platinum-group metals (PGM), i.e. platinum, palladium and rhodium.

Recent advances in polymeric chemically amplified positive resists: Materials and design strategies

Smart Molecules, EarlyView.
This review summarizes recent advances in the molecular design of positive chemically amplified resists, focusing on photoacid generators and polymer architectures. Key strategies for enhancing sensitivity—including self‐amplification effects, copolymerization of sensitive monomers, controlled polymerization, and photosensitized chemically amplified ...

Understanding the Dynamics of Mechanically Interlocked Molecular Systems via Metadynamics Simulations

The Chemical Record, EarlyView.
This Personal Account discusses how molecular simulations help uncover motion, shuttling mechanisms, and kinetics in mechanically interlocked molecules such as rotaxanes and catenanes. Mechanically interlocked molecules, such as rotaxanes and catenanes, display complex internal dynamics and reciprocal motions that are central to their use as artificial

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Statistical Denoising of Transient Rendering

Computer Graphics Forum, EarlyView.
Abstract Transient rendering simulates light in motion, measuring the time of flight from the light source to the camera. However, the stochastic nature of Monte Carlo is aggravated in transient rendering, since samples are now spread along the temporal domain.

A head-to-head comparison of polymer interaction with mucin from porcine stomach and bovine submaxillary glands

Scientific Reports
Native mucus is heterogeneous, displays high inter-individual variation and is prone to changes during harvesting and storage. To overcome the lack of reproducibility and availability of native mucus, commercially available purified mucins, porcine ...

Basis Networks: Learning basis functions for free‐form triangulations

Computer Graphics Forum, EarlyView.
Abstract We present a framework for learning compactly supported basis functions that define tangent continuous surfaces based on coarse irregular triangle meshes. The basis functions are represented as MLPs. Smoothness of the basis functions is achieved by using the values of Loop basis functions as the parameterization of the surface.
