Article Synopsis
- - Surface morphology plays a crucial role in the effectiveness of electrocatalysts, and manipulating atomic-level structures can enhance their performance.
- - The study focused on how heat treatment in a specific reductive atmosphere at 300 °C influences the arrangement of surface atoms in platinum thin-film catalysts, improving their catalytic properties.
- - Results showed that increasing the proportion of (100) planes through thermal annealing can boost catalyst performance for methanol oxidation reactions significantly, highlighting a method for designing better electrocatalysts.
Surrogate optimisation holds a big promise for building energy optimisation studies due to its goal to replace the use of lengthy building energy simulations within an optimisation step with expendable local surrogate models that can quickly predict simulation results. To be useful for such purpose, it should be possible to quickly train precise surrogate models from a small number of simulation results (10-100) obtained from appropriately sampled points in the desired part of the design space. Two sampling methods and two machine learning models are compared here.

It has recently become a focus of study due to the presence of its content of extracellular vesicles (EVs). These uEVs have been found to reflect physiological and pathological conditions in kidney, urothelial, and prostate tissue and can illustrate further molecular processes, leading to a rapid expansion of research in this field In this work, we present the advantages of an immunoaffinity-based method for uEVs' isolation with respect to the gold standard purification approach performed by differential ultracentrifugation [in terms of purity and antigen presence.

This case presentation aimed to describe swallowing difficulty as a leading symptom of hypercalcemia.
Case Report: A 62-year-old man experienced vomiting, dysphagia bordering with aphagia, and 20-kg weight loss in a 2-month period.
