김현철 교수의 연구실은 코ordination 폴리머 및 금속-유기 프레임워크 분야에서 활발한 연구를 수행하고 있습니다. 주로 코발트 기반 2차원 및 3차원 구조를 가진 금속-유기 고체를 합성하고, 그 구조적 특성과 상호작용 메커니즘을 X선 회절을 통해 규명합니다. 특히 글루타르산 및 비피리딘 유도체 리간드를 이용한 새로운 Co(II) 고체의 설계와 물리화학적 성질 분석에 중점을 두고 있습니다. 이는 에너지 저장, 가스 흡착, 촉매 등 응용 가능성이 높은 기초 소재 개발에 기여하고 있습니다.

Magnetic nanoparticle-conjugated polymeric micelles (MNP-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy. Doxorubicin (DOX) was encapsulated in MNP-PMs, and an alternating magnetic field (AMF) resulted in an increase to temperature within a suitable range for inducing hyperthermia and a higher rate of drug release than observed without AMF. In vitro cytotoxicity and hyp
The nucleon form factors of the energy–momentum tensor are studied in nuclear medium in the framework of the in-medium modified Skyrme model. We obtain a negative D-term, in agreement with results from other approaches, and find that medium effects make the value of d1 more negative.
We employ the chiral quark-soliton model to describe excited baryons with one heavy quark. Identifying known charmed baryons with multiplets allowed by the model, we argue that apart from regular excitations of the ground-state multiplets, two out of five narrow ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ states, recently reported by the LHCb Collaboration, may correspond to the exotic pentaquarks. This interpretation can be easily verified experimentally, since exotic ${\mathrm{\ensuremath{\Omega}
Among male and female South Korean elite wrestling athletes training for the Olympic Games, most injuries were mild and occurred in the lower extremities. Weight class influenced injury severity in both wrestling styles, and lightweight athletes had higher injury rates.
The electromagnetic form factors of the SU(3) octet baryons are investigated in the semibosonized SU(3) Nambu--Jona-Lasinio model (chiral quark-soliton model). The rotational 1/${\mathit{N}}_{\mathit{c}}$ and strange quark mass corrections in linear order are taken into account. The electromagnetic charge radii of the nucleon and magnetic moments are also evaluated. It turns out that the model is in remarkably good agreement with the experimental data. \textcopyright{} 1996 The American Physical
