High temperatures as well as local temperature peaks and their gradients within the individual components of industrial furnaces are a challenge for the durability of the furnace.
However, controllable synthesis of stable metal nanoclusters is a challenge, and the durability of metal clusters suffers from the deficiency of dissolution, aggregation, and sintering during catalysis reactions.
The compressive strength, frost-resistance and thermal conductivity of products meet the requirements of Chinese autoclaved aerated concrete blocks standard, however, the shrinking of non-autoclaved aerated concrete is still a challenge and the durability also must be observed in the next work.
Chris Robshaw was named man of the match, but the Bath No10 made a significant difference, taking the ball flat, challenging the defence and having the durability to ride a number of typically shuddering Samoan tackles.
The identification of affordable healing agents for cement based materials, able to promote autonomous crack healing, is a challenge to improve the durability of building structures.
Microbial deterioration of polyurethane (PU) leather coating continues to represent a significant challenge in maintaining the durability and hygiene of leather products.
A major challenge in determining the durability of composites is that their wear resistance is not a simple or intrinsic material property, like elastic modulus, strength, and fracture toughness.
I have come to believe that the achievement of longevity will bring the challenge of durability to the forefront of modern healthcare.
However, more often than not, the situation where one or two of the three factors are not met occurs and the orthopedic surgeon is faced with challenging questions associated with the durability of TKA, the correctness of an established diagnosis to be causing the current symptoms, and postoperative patient satisfaction.
In this work, we challenge this expectation by revisiting the durability choice problem for spacecraft in the face of reduced launch price and under various cost of durability models.
