“…wood harvested from plantation forestry located in Fujian Province, China. Wood blocks with the dimensions 20 mm 3 × 20 mm 3 × 160 mm 3 and 50 mm 3 × 50 mm 3 × 70 mm 3 (longitudinal × tangential × radial) were cut from the sapwood around the 21st growth ring. The initial moisture content was about 11%.…”

“…Pinus massoniana Lamb., commonly known as Masson pine, is one of the most widely distributed tree species in the subtropical regions of China [1]. The wood from Masson pine planted forests has become an important industrial raw material for wide commercial use such as wood construction, wood-based panels, and polymer composites due to the beautiful wood grain, good adaptability to the environment, and shorter growth cycle [2,3]. However, as one of the common fast-growing tree species, Masson pine wood also presents drawbacks which limit its practical application, such as low dimensional stability, softness, and low bio-durability [4,5].…”

The local chemistry and mechanics of the control and phenol formaldehyde (PF) resin modified wood cell walls were analyzed to illustrate the modification mechanism of wood. Masson pine (Pinus massoniana Lamb.) is most widely distributed in the subtropical regions of China. However, the dimensional instability and low strength of the wood limits its use. Thus, the wood was modified by PF resin at concentrations of 15%, 20%, 25%, and 30%, respectively. The density, surface morphology, chemical structure, cell wall mechanics, shrinking and swelling properties, and macro-mechanical properties of Masson pine wood were analyzed to evaluate the modification effectiveness. The morphology and Raman spectra changes indicated that PF resin not only filled in the cell lumens, but also penetrated into cell walls and interacted with cell wall polymers. The filling and diffusing of resin in wood resulted in improved dimensional stability, such as lower swelling and shrinking coefficients, an increase in the elastic modulus (Er) and hardness (H) of wood cell walls, the hardness of the transverse section and compressive strength of the wood. Both the dimensional stability and mechanical properties improved as the PF concentration increased to 20%; that is, a PF concentration of 20% may be preferred to modify Masson pine wood.

The production of energy from wood biomass is as old as humanity itself. There has been enormous progress in research of sustainable pyrolysis processes for optimal energy conversion in the past 30 years. Pyrolisis–gas chromatography–mass spectrometry (PY‐GC‐MS) was used to examine the components of bark and wood of Toona sinensis for expanding high value utilization different parts of trees. In the study, 174 chemical constituents were identified in the bark; 169 chemical constituents were identified in the wood, respectively. The chemical composition of bark is different from that of wood. The change in thermal cracking 30 min ago is not very large. In the retention time is more than 30 min, they are very different. Because the ash content of bark had much large corresponding wood. Mainly the phenols and their derivatives formed after the pyrolysis of lignin and extractives. The chemical composition of T. sinensis provides a scientific basis for the development and utilization of the plant. The richer chemical constituents of T. sinensis are found, which will provide new scientific evidence for further development and utilization of bark and wood of T. sinensis.

“…The fresh pitaya pulp and pericarp were separated, and the pericarp and pulp were weighed and basically controlled within the range of 100 g + 5 g 23 . For the pulp, pour the ethanol with 1:5 ratio into the pulp and then use the blender to crush it and reserve it 24–26 . The pericarp of pitaya is crushed by BX484 type pulverizer, and the ethanol with material to liquid ratio of 1:5 is added 27 .…”

Pitaya is rich in nutrition and unique in function and contains vegetable albumin, anthocyanins, rich vitamins, and water soluble dietary fiber, which are rare in fruits and vegetables. However, researches mostly focused on pitaya cultivation, biological characteristics, fresh‐keeping, and lacked analyses about chemical composition of pitaya. Therefore, ethanol extraction and GC/MS were used to extract and identify the bioactive components in pulp and pericarp of red pitaya and white pitaya. The extracting results showed that percentages of ethanol extracts from pulp and pericarp of red pitaya were 14.5% and 12%, whereas those of white pitaya were 16% and 12%. The GC/MS results showed that different kinds of bioactive constituents were identified in fresh pericarp and pulp of red pitaya and white pitaya. In the four ethanol extracts, there are rich polysiloxane plant organosilicon with total contents of 10.09%, 24.21%, 25.77%, and 23.25%. Meanwhile, there are many heterocyclic substances, and the content of pericarp is much higher than that of pulp. The four ethanol extracts also contain some other bioactive ingredients, such as esters, hydrocarbons, alcohols, amides, halides, and fatty acids, which can be used as raw materials for biomedicine, advanced cosmetics, and skin care products.
