Reduced compression time is not sufficient for stability in patellar buttons

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellar resurfacing in total knee arthroplasty requires stable cement fixation of the patellar button. Unlike femoral and tibial components, the patellar button is held under manual compression until cement curing, potentially prolonging operative time.

Green polyurethanes from bio-based building blocks: Recent advances and applications

Green Synthesis and Catalysis
Polyurethanes (PUs) are among the most studied, manufactured, and employed polymers due to their versatility and wide range of applications. However, their synthesis generally relies on toxic, non-renewable, and harmful petroleum-based chemicals.

Tuning Degradation of Polylactic Acid via Size‐Controlled Silica Nanoparticles

Polymer Engineering &Science, EarlyView.
Particle size emerges as a simple handle to program polymer degradation. By tailoring the size of silica nanoparticles, the degradation behavior of polylactide composites can be directed towards accelerated hydrolysis or enhanced composting‐induced disintegration without changing the polymer chemistry.

Direct extraction of functional whitened lignocellulose from wood via isocyanate modification in water–ethanol mixture

Polymer International, EarlyView.
Direct extraction of lignocellulose from wood derivatives was achieved by introducing a bulky isocyanate substituent to lignin in a water–ethanol mixture. This process exploits the tunable solvent affinity of lignin to achieve its whitening, enabling the isolation of lignocellulose.

Reaction of acyl(aroyl) isocyanates with dimedon [PDF]

, 1981
The benzoyl and trichloroacetyl isocyanates react with dimedon to give the [4 + 2]-cycloadducts and the O- and C-addition products, whereas trifluoroacetyl isocyanate reacts to give the acid azomethine.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.
