Microstructural evolution and cyclic oxidation of Pt-Al-YSZ coating under thermal shock

Materials Research Express, 2020
In this research, the effect of thermal shock has been investigated on the microstructure and cyclic oxidation of Pt-Al-7%YSZ coating applied on Rene-80 superalloy.

Laparoscopic Methylene Blue Photodynamic Therapy for Intraabdominal Infection: A Preclinical Feasibility Study in a Rabbit Model of Perforated Appendicitis

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Perforated appendicitis commonly results in intra‐abdominal infection requiring prolonged antibiotic therapy. Intraoperative antimicrobial adjuncts are limited, and photodynamic therapy (PDT) may provide a targeted, resistance‐independent approach.

SEARCHING FOR RATCHET EFFECTS IN AGRICULTURAL CONTRACTS

Journal of Agricultural and Resource Economics, 1999
In a dynamic contracting environment, increasing standards over time in light of past performance is known as the ratchet effect. Despite the recent theoretical attention given to the ratchet effect, models that include these effects have not been empirically tested against contract data.

Effects of adjustable‐volume transfemoral prosthetic sockets on balance and falls: A randomized clinical trial

PM&R, EarlyView.
Abstract Background Adjustable‐volume prosthetic sockets have been developed to allow users to accommodate volume fluctuations throughout the day. Improvement in socket fit is thought to enhance the connection between the user's residual limb and prosthesis and may therefore improve postural control and balance.

Electrochemical investigation of radical‐radical recognition in viologen‐based ditopic structures

Responsive Materials, EarlyView.
The so‐called “blue box” is one of the most studied macrocycles. Yet, functionalized macrocycles of this type are rarely investigated. This work describes the radical‐radical recognition properties of ditopic structures, including functionalized blue‐box macrocycles.

Spatial Activity Patterning and Topological Defect Transport in Acoustically Energized Active Liquid Crystals

Small, EarlyView.
Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Molecular Active Matter, Kinetic Asymmetry, and Non‐Reciprocal Interactions

Small, EarlyView.
Nanoscale enzymes constitute dissipative active matter that converts scalar energy input into vectorial outputs. Through kinetic and diffusion asymmetry, they break time and space symmetry, resulting in directional motion. This mechanism accounts for both positive and negative chemotaxis, as well as non‐reciprocal interactions between enzymes that ...

The investigation on the bending fatigue properties of Ti–6Al–4V lattice sandwich structures fabricated EB-PBF

Journal of Materials Research and Technology
In this study, lattice sandwich structures of Ti–6Al–4V alloy with simple cubic (SC) and rhombic dodecahedron (RD) unit cells were prepared by electron beam powder bed fusion (EB-PBF) technique.

The Feasibility of Household Food Waste Reduction in Finland: Insights From Five Consumer Profiles

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT We apply a household production framework to analyse how changes in cooking skills, waste‐abatement costs and wage rates influence the food waste behaviour of five consumer profiles in Finland. We find that achieving a given reduction in food waste through skill‐enhancing interventions induces larger behavioural adjustments than equivalent ...

The concurrent ratcheting and stiffness degradation-based damage variable in SA508 steel samples undergoing stress cycles at room and elevated temperatures

Materials Research Express
This study evaluates the interaction between ratcheting and stiffness degradation in SA508 steel samples at various operating temperatures using a combined isotropic-kinematic hardening framework.
