Multiscale analysis of CO adsorption mechanisms on porous carbon: An investigation into the impact of intrinsic defects and pore size.

Porous carbon adsorption represents a critical component of CCUS technologies, with microporous structures playing an essential role in CO capture. The preparation of porous carbon introduces intrinsic defects, making it essential to consider both pore size and these defects for a comprehensive understanding of the CO adsorption mechanism. This study investigates the mechanisms of CO adsorption influenced by intrinsic defects and pore size using multiscale methods, incorporating experimental validation, Grand Canonical Monte Carlo simulations, and Density Functional Theory simulations.

Blood flow dynamics in the ascending aorta of patients with bicuspid aortic valve before and after transcatheter aortic valve replacement: a computational fluid dynamics study.

Background: Abnormal blood flow patterns are known to contribute to the ascending aortic dilation in patients with bicuspid aortic valve (BAV). The present study elucidated the blood flow characteristics in the dilated ascending aorta before and after transcatheter aortic valve replacement (TAVR) using computational fluid dynamics (CFD) analysis.

Methods: We performed CFD analysis in three BAV patients with ascending aortic dilation (maximum diameter ≥ 45 mm) who underwent TAVR.

A perfect ultra-wideband solar absorber with a multilayer stacked structure of Ti-SiO-GaAs: structure and outstanding characteristics.

In this paper, we introduce an entirely new solar absorber design-a multi-layer periodic stacked structure. Through coupling effects, this design has perfect ultra-wideband absorption characteristics. The absorber structure is composed of four absorption units with varying cycle lengths, which are cyclically stacked on the surface of the refractory metal Cr.

Programmable Circular Multispecific Aptamer-Drug Engager to Broadly Boost Antitumor Immunity.

Safely and effectively harnessing innate immunity to boost cancer immunotherapy is promising yet challenging. Hence, we have developed a series of programmable aptamer-based multispecific engagers by encoding various artificial aptamer-drug codons with DNA-templated polymerization, aiming to broadly boost innate and adaptive immunity for antitumor therapy. All circular single-stranded multivalent aptamer-drug conjugates (os-mvApDCs) had a dendritic structure, precise size, and excellent stability, enabling prolonged blood circulation, targeted tumor accumulation, and rapid multireceptor-mediated endocytosis.

Biomechanical Evaluation of the Effect of Varying Humeral Implant Length in Total Elbow Replacement: A Finite Element Analysis.

Background: Total elbow arthroplasty (TEA) is increasingly used for expanding indications but complications like aseptic loosening and periprosthetic fractures persist. Our objective is to examine the biomechanical behavior of the total elbow implant in response to varying implant lengths by investigating the stresses and the stress shielding effect in the bone-implant assembly using finite element (FE) modelling.

Methods: A fourth-generation synthetic humerus sawbone and its corresponding digital model were used in this study.
