Cellulose attracts attention not only as the most abundant biomass but also as a functional materialpresumably because of the presisely designed structure. In this article, some recent advances in the field offine chemistry based on the molecular interction between cellulosics and an organic molecule including carbonnanotubes（CNT）, those are CNT binder, chiral stationary phase, and chiral reaction catalyst. Some insightsinto the interaction mechanisms are also given, in which stacking between the pyranose ring and π-bondsystem of aromatic molecule was emphasized.

The greatest merit of adhesion bonding is that dissimilar materials can be bonded and integrated. Onthe other hand, it is becoming more important how to select the appropriate adhesives that can cope withdiversified adherend and sophisticated required performance. In this review, adhesives are classified fromvarious viewpoints, and their general characteristics will be explained.Adhesives are roughly classified into“ Inorganic Adhesives” and“ Organic Adhesives”. Further,“ OrganicAdhesives” are classified into“ Natural Adhesives” and“ Synthetic Adhesives”. In recent years, the SyntheticAdhesives are used for industrial applications widely. Also, adhesives are classified from the viewpoint ofrequired functions, such as“ Structural Adhesives”,“ Elastic Adhesives”,“ Fast-curing Adhesives”,“ ConductiveAdhesives（ Electrically / Thermally）” and“ Flame Retardant Adhesives”, and so on.In order to select appropriate adhesives and to obtain effective adhesion results, it is necessary to make fulluse of various knowledge such as adhesion mechanism and theory, features of the adherend to be adhered,structure design of the bonded part. Finally, it is also important to check on actual parts and on-site use.

Previously, the mechanical properties of calcium carbonate (CaCO₃) particles-filled isoprene rubber wasimproved by the surface treatment with a mixture of amino- and mercapto-functional silane coupling agents(SCA) having trialkoxy structure [J. Adhesion Soc. Jpn., 50, 131 (2014).]. To investigate the reinforcingmechanism, the treated layer on CaCO₃ surface was analysed. The quantity of SCA unremoved by alcoholwashing measured using thermogravimetry was greater for amino- than for mercapto-functional SCA and forthe tri- than for the dialkoxy structure. Almost all of adsorbed SCA was removed by water washing for thetreated with amino-functional SCA, because the adsorption of SCA is caused by an inonic interaction betweenamino group in SCA and CaCO₃ surface. The molecular mobility of polycondensate of the mixtures with thetrialkoxy structure measured using 1H pulse nuclear magnetic resonance had the least molecular mobility, i.e.,formed the highest density network. An inonic nteraction between the amino group and the CaCO₃ surface andhigh density network formation by trialkoxy structure were found to be important for effective reinforcement.

The effect of adherend shape and size on the cyanoacrylate adhesive area of single lap joint, the effect ofcuring time on the adhesive strength of the cyanoacrylate adhesive resin and the correlation between adhesivestrength and analysis result of the polymerization reaction were investigated. As an adherend, rolled steelmaterial SS400 for general structure was used. After the milling process the bonded surface was grinded tomake the roughness of adhesive surface constant. The humidity during bonding and curing was kept constant.As a result, the adhesive strength increased as the curing time increased. And the experiment showed thatthe adhesive length mostly influenced on the adhesive strength. And it showed that it was possible to presentthe curing process of the adhesive by the correlation between the adhesive strength and the polymerizationreaction.
