Radar Absorbing Materials(RAM)are a class of composites that can attenuate incident electromagnetic waves to avoid radar *** carbon allotropes that have the potential to be used as RAM are either carbon nano-tubes(cNTs),graphene,carbon black(cB)and ultimately,sustainable porous carbon(SPc).Here,black wattle bark waste(following tannin extraction)was used as a sustainable source to produce SPc made from biomass *** was characterized and used as afiller for a silicone rubber matrix to produce aflexible *** elec-tromagnetic performance of this composite was compared with composites made with commercial cB and cNT through reflection loss(Rl),where-10 dB is equivalent to 90%of *** composites were evaluated in single-layer,double-layer,and as radar absorbing structures(RAS)with the aim of improving their effective absorption bandwidth(EAB)performances and a reduction in *** cNT composite presented a Rl of-26.85 dB at 10.89 GHz and an EAB of 2.6 GHz with a 1.9 mm thickness,while the double-layer structures using cNT and SPc provided a Rl of-19.74 dB at 10.75 GHz and an EAB of 2.51 ***,the double-layer structures are~42%cheaper than the composite using only cNT since less material is ***,the largest EAB was achieved with a RAS using SPc,reaching~2.8 GHz and a Rl of-49.09 dB at 10.4 ***,SPc made of black wattle bark waste can be a competitive,alternative material for use as RAM and RAS since it is cheaper,sustainable,and suitable for daily life uses such as absorbers for anechoic chambers,sensors,and elec-tromagnetic interference shields for electronics,wallets,vehicles,and others.

World Journal of Gastroenterology 2007年第40期13卷 5317-5323页

作者： Ezra Gabbay Ehud Zigmond Orit Pappo nila Hemed Mina Rowe George Zabrecky Robert cohen Yaron Ilan liver Unit Department of Medicine Department of Pathology Hebrew UniversityHadassah Medical CenterJerusalem IL-91120Israel Marcus foundation AtlantaUnited States

AIM： TO assess the safety and efficacy of antioxidant therapy for patients with chronic hepatitis c virus （HcV） infection.METHODS： One hundred chronic HcV infection patients failed in interferon treatment were enrolled and randomly assigned to receive combined intravenous and oral antioxidants or placebo, or oral treatment alone, Primary end points were liver enzymes, HcV-RNA levels and histology.RESUlTS： combined oral and intravenous antioxidant therapy was associated with a significant decline in AlT levels in 52% of patients who received antioxidant therapy vs 20% of patients who received placebo （P = 0.05）. Histology activity index （HAI） score at the end of treatment was reduced in 48% of patients who received antioxidant therapy vs 26% of patients who received placebo （P = 0.21）. HcV-RNA levels decreased by l-log or more in 28% of patients who received antioxidant therapy vs 12% who received placebo （P = NS）. In part 11 of the trial, oral administration of antioxidants was not associated with significant alterations in any of the end points.cONclUSION： Antioxidant therapy has a mild beneficial effect on the inflammatory response of chronic HcV infection patients who are non-responders to interferon. combined antiviral and antioxidant therapy may be beneficial for these patients.
