Lead toxicity is an alarming global threat that intoxicates multiple organs particularly the brain. Prolong lead exposure resulted into approximately 494,550 deaths and contributed around 10% of intellectual disability globally. Recently the use of curcumin (Cur) as an alternative therapy for the treatment of heavy me…

O Cross Laminated Timber (CLT) e um sistema construtivo que vem ganhando destaque na construcao civil nos ultimos anos devido as questoes de sustentabilidade, visto que este sistema tem como materia-prima a madeira de floresta plantada. A fomentacao do CLT desperta o interesse e a preocupacao de projetistas, engenheir…
It is our pleasure and honour to introduce this prestigious publication – The Proceedings of the Institute of Physics International Conferences Electrostatics 2019 and Dielectrics 2019. The conferences were organised by the Dielectrics & Electrostatics Group of the Institute of Physics, and for the first time were co-…
Asphaltic aviation pavements experience severe damage on a routine basis from exposure to petrol, oils and lubricants from the inadvertent leaking aircraft and poor maintenance practices. A review of preventative treatments in use show that fuel-resistant asphalt and membranes are available, however not often utilised…
The development of cost-effective and scalable synthetic methods is of paramount importance \nto achieve industrial application of energy conversion and storage devices based on layered \ndouble hydroxides (LDH). Herein, we synthesized NiCo-LDH nanosheets via a simple up scalable co-precipitation method at relatively…
Carbon nanotube based devices are foreseen as the vital candidates for \nfabricating high-performance logic blocks that can be operated in the \nsub 22nm regime. Unlike their silicon-based counterparts, these \nCNTFET devices can be operated without getting affected by short \nchannel issues of downscaled technology.…
The use of innovative material such as graphene could potentially contribute to the strengthening of today’s infrastructures, and further extending the service life of the infrastructures. Graphene material properties far exceed any other material and have been proven to be an advanced and durable material in structur…
An increase awareness in climate change has pushed governments to tighten regulations surrounding environmental emissions limits for industry. Existing industrial plants are required to meet these new regulations, which requires the implementation of innovative technologies. These retrofits are very costly for older f…
The project was carried out to determine what light naphtha fuels could be potentially refined and used as a n additive in diesel fuel without compromising on performance or emission parameters negatively. Research was conducted to determine viable light naphtha fuels from oil refinery data sheets and chemical analysi…
The left internal mammary artery (LIMA) has been used as a conduit for coronary artery revascularization since 1968. Here we are reporting A total of 48 consecutive patients were operated upon using double mammary arteries. All of them received a mammary graft to the left anterior descending artery (LAD). All 48 of th…
DRM is one of the alternatives to produce syngas by utilizing the main greenhouse gases which are CO2and CH4to reduce environmental emissions. However, the use ofNi-basedcatalysts. i.e.Ni/Al2O3 catalyst for DRM reaction brought a drawback impact to the reaction as it contributes to the formation of coke and sintering…
The biggest challenges in investment casting of titanium alloys are the high melting temperature and the extreme reactivity of the melt. For this reason, a new ceramic material for crucibles and precision casting molds based on calcium zirconate (CaZrO3) has been developed. The quality of titanium castings, however, i…
전북 완주 신풍유적 출토 고려시대 슬래그와 송풍관을 대상으로 신풍유적의 야동기술(冶 銅技術)성격을 확인하고, 납 원료산지를 추정하기 위해 납동위원소비를 실시하여 알아보았다. 성분분석 결과, Cu-Sn-Pb 삼원계 합금하는 과정에서 비롯된 슬래그와 송풍관으로 해석되었다. 금속현미경과 주사전자현미경(scanning electron microscopy-energy dispersive spectrometer) 분석결 과, 동괴와 주석괴에 방연석을 첨가하여 완제품 제작을 위한 중간소재를 생성하는 합금단계에 서 발생한 부산물로 추정된다. 납동위원소비분석 결과, 한국 남부 Zo…
Foundries which utilize bentonite clay powders often face problems such as excessive sand quantities in circulation along with inadequate granular sand composition, i.e. sand that contains excessive fine fractions and inert substance proportions. There is a high correlation between fine fractions, inert substances in…
직조 구조의 복합재의 쓰임이 자동차, 항공 산업 등 여러 분야로 확장됨에 따라, 직조 복합재의 신뢰성 문제 및 물성예측에 대한 필요성이 대두되었다. 본 연구에서는 직조 구조가 다른 복합재료의 물성 예측을 위한 유한요소해석을 수행하여 실험으로 얻은 정적 물성과의 유사성을 검증하였고, 효과적인 모델링 방법을 개발하였다. 직조 구조의 특성을 반영하기 위하여 모델링은 메소 스케일의 대표 체적 요소(RVE)를 이용하였다. 섬유 다발과 순수 기지를 분리하여 3차원 모델링을 진행하였다. 하신 파괴 기준(Hashin’s failure criteria)을 적용하여 요소의 파괴 유무…
MCM-41@L-Arg@Pd(0) has been prepared by some consequence reactions. This nano structural material has been characterized via different technique including: XRD, TGA, BET, EDS, X-Ray maps, SEM, ICP-OES and FT-IR analysis. The synthesis of a variety of biphenyl compounds has been achieved successfully via a reaction of…

A thermal barrier coating system survived burner rig testing at 1300 C for 500 h. A 160 m thick yttria stabilized zirconia (YSZ) coating was applied to a Ti2AlC MAX phase bar sample by plasma spray physical vapor deposition (PS-PVD) and tested face-on in an atmospheric Mach 0.3 jet fuel burner, using 5-h thermal cycle…
