Research Progress on Chitinase and Chitosanase with Transglycosylation Activity

Shipin gongye ke-ji
N−acetyl chitooligosaccharides and chitooligosaccharides with high degree of polymerization are highly valued for their superior bioactivities. However, traditional preparation methods face various limitations, such as uncontrollable processes and ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Development of a Hybridized Model for Predicting the Life Span of Power Transformers

Journal of Applied Sciences and Environmental Management, 2019
Power transformers are important equipment of the electrical switchyard whose failure leads to long hours of outage. In this research, a two-stage hybridized model for determining the lifespan of power transformers is presented by using the furan ...

Determination of Degree of Polymerization of Sodium Alginate

The Journal of the Society of Chemical Industry, Japan, 1958
100～1000cp(1%)程度の市販高粘性工業用アルギン酸ソーダに対し,粘度法による重合度測定方法をStaudinger, Arrhenius, Philippoff,の三式について検討し,その結果低分子電解質(カセイソーダまたは炭酸ソーダ)の添加濃度は0.5%でよいことが観察された。また,Staudingerの粘度式は,高粘性工業用アルギン酸ソーダに対し適用困難であるが,Arrhenius, Philippoffの両式は浸透圧法による結果と大体近似し,適当であることを明らかにした。

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Mechanistic studies of plasma polymerization [PDF]

, 1995
Plasma polymerization is a solventless method for depositing polymeric layers onto any substrate at room temperature. This technique comprises excitation, fragmentation, and polymerization of precursor molecules by an electrical discharge.

Polymerization-Induced Cooperative Assembly of Block Copolymer and Homopolymer via RAFT Dispersion Polymerization

, 2017
Polymerization-induced cooperative assembly (PICA) is developed to promote morphological transitions at high solids via RAFT dispersion polymerization, using both a macromolecular chain transfer agent (macro-CTA) and a small molecule chain transfer agent
