Abstract The infrared spectra of oriented films valonia cellulose and ramie bacterial crystallites have been observed in the 3 μ region. Polarization properties bands also determined. differences between polarized this region are attributed to per cent crystallinity orientation effects. Two new CH stretching observed. With information 2 symmetric antlisymmetric modes assigned parallel perpendicular bands, respectively, requiring a specific OH group. From polarization region, system hydrogen...

Data obtained deuterated material, polarizations, tilting effects also used. perpendicular at 1317 is assigned CH 2 wagging mode. highly parallel 1162 antisymmetric bridge COC stretching frequency slightly 1110 a...
Abstract The polarized infrared spectra of crab chitin crystallites, blowfly larval cuticle, lobster tendon, and partially deacetylated have been studied. In addition, the amorphous chitin, deuterated crystalline N ‐acetylated chitohexaose were obtained analyzed. Band assignments made with aid previous work on celluloses other related molecules. complete intermolecular CO‐‐‐‐HN hydrogen bonding scheme, orginally proposed by Carlstrom from x‐ray studies, is in agreement data. With a scale...

Recently, CdS has been intensively investigated for its excellent photocatalytic hydrogen (H2) evolution property. However, the poor stability and serious photocorrosion severely influence potential practical application. In this work, we successfully synthesized Bi surface plasmon resonance (SPR)-promoted Z-scheme Bi2MoO6 nanosheet/CdS-diethylenetriamine (Bi–Bi2MoO6/CdS-DETA) composites via an in situ solvothermal method. Crystalline structure, morphology, electrochemical properties, along...

Photocatalytic CO 2 reduction to value‐added fuels is an appealing avenue in response global warming and the energy crisis, but it still suffers from high barriers, low conversion efficiencies, poor photostability. Herein, a novel S‐scheme SnNb O 6 /CdSe–diethylenetriamine (SNO/CdSe–DET) heterojunction designed by microwave‐assisted solvothermal process, composed of 2D ultrathin SNO nanosheets (NSs) amine‐modified CdSe–DET nanorods (NRs).
