For powder-bed electron beam additive manufacturing (EBAM), support structures are required when fabricating an overhang to prevent defects such as curling, which is due to the complex thermomechanical process in EBAM. In this study, finite element modeling is developed to simulate the thermomechanical process in EBAM in building overhang part. Thermomechanical characteristics such as thermal g...

An approach to reversibly control the curling and unfolding of graphene hybrid materials by porphyrin interactions on the basal planes of graphene has been developed, and the curled graphene hybrid materials have enhanced photoelectrochemical and optical limiting performance.

antitumor and antifungal agents. Recently, curacin A, which is a potential antitumor agent, was isolated from marine cyanobacterium (blue-green alga) Lyngbya majuscula as an antimitotic cytotoxic component.1} We have reported an effective assay method for antimitotic substances, which observes deformations of mycelia germinated from conidia of Pyricularia oryzae P-2b, and certain antimitotic co...

A bioassay method detecting deformations of mycelia germinated from conidia of Pyricularia oryzae P-2b, has been modified to give quantitative estimations. The method was first developed using antimitotic agents which showed characteristic curling effect. Morphological deformations include curling, swelling, hyper-divergency, beads shape and so on, and inhibition of the germination was also obs...

Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on el...

The exchange coupling between a hard magnetic layer MnBi and soft Co-Fe has been found to significantly improve the maximum energy product. In this work, spin structure of exchange-coupled MnBi:Co-Fe bilayers is experimentally investigated by X-ray circular dichroism (XMCD) polarized neutron reflectometry (PNR). We find that out-of-plane magnetization reversal process bilayer involves formation...

Polymersomes, which are stable and robust vesicles made of block copolymer amphiphiles, are good candidates for drug carriers or micro/nanoreactors. Polymer chemistry enables almost unlimited molecular design of responsive polymersomes whose degradation upon environmental changes has been used for the slow release of active species. Here, we propose a strategy to remotely trigger instantaneous ...
