The Red-cockaded Woodpecker: Interactions With Fire, Snags, Fungi, Rat Snakes, and Pileated Woodpeckers [PDF]

open access: yes, 2004
Red-cockaded woodpecker (Picoides borealis) adaptation to fire-maintained southern pine ecosystems has involved several important interactions: (I) the reduction of hardwood frequency in the pine ecosystem because of frequent tires, (2) the softening of ...

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production

open access: yesCarbon Energy, EarlyView.
Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

open access: yesCarbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Glucomannan Isolated from Red Pine Pulp.

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1959
赤松パルプ中のグルコマンナンを2 種類の方法を用いて単離し, 他の木材グルコマンナンと比較した。第1 の方法はパルプを銅アンモニア溶液で2回処理して得られる不溶部分を8%カセイソーダに溶解し,フェーリング液を加えて沈殿させ精製するもので,この方法によるグルコマンナンのマンノース基/グルコース基=M/Gは1.9~2.3であった。第2の方法はパルプの17.5%カセイソーダ抽出液にフェーリング液を加えて沈殿させ,これを再びカセイソーダに溶解しフェーリング液で沈殿させ精製するもので,M/Gは2.7になるが,約10%のキシロース基を含みこれを除くことが難しい。これらの結果は,赤松中のグルコマンナンのM/Gが従来単離されていた針葉樹グルコマンナンのM/Gより低いことを示している ...

Utilization of Nest Boxes by the Southern Flying Squirrel, Glaucomys volans, in Central Arkansas [PDF]

open access: yes, 1977
Thirty-five nest boxes were placed 4.5-5.5 meters above the ground in an eight acre mixed pine-hardwood plot 20 km SE of Bryant, Saline County, Arkansas. These boxes were monitored from February, 1972, to May, 1975.

S‐Doped Carbon Nitride Thin Films From a Triazole Precursor

open access: yesCarbon Innovation, EarlyView.
Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.
