Microfibrillated Cellulose from Pineapple Leaves for Synthesizing Novel Thermal Insulation Aerogels

Chemical Engineering Transactions, 2022
Aerogels from cellulose and its derivatives, especially cellulosic wastes, have been known as an excellent heat insulation material in steam generation, buildings, intelligent food packaging, fire-retardant clothing, and thermal protective equipment because of their lightweight properties, high stability, and extremely low thermal conductivities ...

Characterization of Phosphoenolpyruvate Carboxykinase from Pineapple Leaves Ananas comosus (L.) Merr. [PDF]

Plant Physiology, 1977
Phosphoenolpyruvate carboxykinase has been partially purified from pineapple (Ananas comosus [L.]) leaves. Specific activities obtained show it to be a major activity in this tissue. Above 15 C, the respective activation energies for decarboxylation and carboxylation are 13 and 12 kcal/mol.

Study of Extraction, Treatment and Characterization of Pineapple Leaves Fibers as Potential Utility in Textile Industry

IDOSR JOURNAL OF EXPERIMENTAL SCIENCES
Extraction, treatment and characterization of pineapple leaves fibres was achieved. The study revealed that water retting is the best way to extract fibers as it is easily controlable which reduces the chance of reducing the strength of fibres.

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

Advanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Effects of High Night Temperature on Crassulacean Acid Metabolism (CAM) Photosynthesis of Kalanchoë pinnata and Ananas comosus

Plant Production Science, 2006
The effects of the night temperature on CO2 exchange rate and organic acid accumulation in the leaves of two crassulacean acid metabolism (CAM) plants, Kalanchoë pinnata and Ananas comosus (pineapple), were examined under a fixed day-temperature ...

Morphoanatomical leaf “D” evaluation of pineapple (Ananas comosus (L.) Merr. var. comosus) in response of two cropping systems in Corrientes, Argentina

Acta Agronómica, 2016
A feasible possibility to cultivate tropical species in the subtropics is compensate the limitations of the low temperatures using plastic covers that modify the environment and the consequent crop response.
