novel hydroxyapatite/graphene (HAP/ Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous dispersion containing Na2H2EDTA·2H2O, NaH2PO4 and CaCl2 with a Ca/EDTA/PO4 3? concentration ratio of 0.25/0.25/0.15M, along with 0.01 wt% added graphene nanosheets, at a current density of 137 mA cm?2 and pH value of 9.0. The field emission scanning electron microscopy and transmission electron microscopy observations of the... -
비자발적 조직시민행동이 직무만족에 미치는 영향과 심리적 계약위반의 조절효과

자발적 행동인 조직시민행동이 조직성과에 긍정적인 영향을 미친다는 연구는 꾸준히 진행되어 왔 다. 하지만 본 연구에서는 이와 달리 기업의 성과를 높이기 위해 기업이나 상사로부터 근로자들이 받 는 강박 및 압박에 의해 수행되는 비자발적인 조직시민행동의 부정적인 측면에 대해 살펴보았다. 조 직시민행동이 비자발적인 방식으로 발생하게 되면 근로자들에게 과중한 부담이 발생하여 조직성과는 오히려 감소하게 된다. 그리고 근로자들이 비자발적으로 업무를 수행할 때 조직성과인 직무만족은 감 소될 것이다. 다음으로... -
PR Campaign Creativity Scale : A scale development of validation

This study aimed to develop the scale of creativity in public relations campaigns. Seven elements of creativity in public relations campaigns were identified: novelty, meaningfulness, artistic value, continuity, connectedness, social issues, and synthesis. From the second-order confirmatory factor analysis results, the one-dimensional seven measurement items were listed as follows: The campaign is more novel than existing campaigns; the detailed action plan clearly relays the message that the... -
The effects of carbon coating onto graphite filler on the structure and properties of carbon foams

Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as... -
Functionalization of graphene nanoplatelets using sugar azide for graphene/epoxy nanocomposites

evaluation of its thermo-mechanical performance. Successful functionalization of GnP was confirmed via thermal and spectroscopic study. Raman spectroscopy indicated that the functionalization was on the edge of the graphene sheets; the basal plane was not perturbed as a result of the functionalization. The epoxy/functionalized GnP composite system exhibited an increase in flexural modulus (~18%) and glass transition temperature (~10°C) compared to an un-functionalized GnP based epoxy composite. -
Preparation and application of reduced graphene oxide as the conductive material for capacitive deionization
Ayu Tyas Utami Nugrahenny, Jiyoung Kim, Sang-Kyung Kim, Dong-Hyun Peck, Seong-Ho Yoon, Doo-Hwan Jung 한국탄소학회 Carbon Letters 7 Pages

This paper reports the effect of adding reduced graphene oxide (RGO) as a conductive material to the composition of an electrode for capacitive deionization (CDI), a process to remove salt from water using ionic adsorption and desorption driven by external applied voltage. RGO can be synthesized in an inexpensive way by the reduction and exfoliation of GO, and removing the oxygen-containing groups and recovering a conjugated structure. GO powder can be obtained from the modification of Hummers... -
