Cine Substitution of N-Sulfonylindoles [PDF]

open access: yes, 2023
Nucleophilic substitution at the 2-position of indoles bearing 3-position electron-withdrawing groups follows multiple pathways. Conventional nucleophilic aromatic substitution ensues when there is a 2-position leaving group, but in a cine substitution ...

Synthesis and Characterization of Acetylated Cassava Starch with Different Degrees of Substitution [PDF]

open access: yesBrazilian Archives of Biology and Technology, 2020
Abstract Acetylated cassava starch with low and medium degrees of substitution (DS) were synthesized. Also, the effect of DS on swelling power, solubility, morphological properties, gelatinization temperature, paste clarity and moisture sorption were studied. Swelling power and solubility in water between 50ºC and 90°C were determined.

Preparation of Starch Stearate Ester and Stability of Pickering Emulsion

open access: yesShipin gongye ke-ji, 2023
Using rice starch as raw material, starch stearate ester (SSE) was prepared by microwave-assisted method, and the SSE and its Pickering emulsion were characterized. The results showed that with the increase of stearic acid (SA) addition, the substitution

Tailoring nanofibrillated cellulose through sonication and its potential use in molded pulp packaging

open access: yesNanocomposites, 2021
Nanofibrillated cellulose (NFC) was systematically tailored by ultrasonic-assisted esterification with lactic acid at different amplitudes and times, which led to modified NFC (mNFC) with different degrees of substitution (DS), between 0.21 and 0.55, as ...

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Chemical characterization of black poplar (Populus nigra L.) sawdust hemicelluloses esterified with acyl chlorides

open access: yesTurkish Journal of Forestry, 2021
In the present study, hemicelluloses were isolated from black poplar (Populus nigra L.) sawdust, which is generated by the wood industry in large quantities as lignocellulosic waste. The monosaccharide composition of hemicelluloses was determined by gas
