Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding natural history HBV potential for therapy resultant disease is continuously improving. New data become available since previous APASL guidelines management were published 2012. The objective this manuscript to update recommendations optimal infection. 2015 developed by a panel Asian experts chosen APASL. clinical practice are based on evidence...

The lamination process involves simultaneous thermal releasing deposition of during annealing resulting exhibits promising power conversion efficiency approximately 76% that standard opaque device an Ag metal electrode. asymmetric photovoltaic performances while illuminated from two respective sides were further...
The external quantum efficiency of solar cells can be improved by using texturing pyramid- and honeycomb-like structures with minimum reflection. In this study, we investigated the reflection properties through rigorous coupled-wave analysis three-dimensional finite-difference time domains (FDTD) method to analyze close-packed structures. We also demonstrate a simple method-combining sub-wavelength-scale monolayer bilayer polystyrene spheres one-step reactive ion etching process-to fabricate...

The hydrophobic concentrating effect petals allows us to concentrate metal nanoparticle (NP) aggregates and analytes onto their surfaces. From systematic investigation SERS performance when using upper lower epidermises as find that epidermis, with its quasi-three-dimensional (quasi-3D) nanofold structure, is...
Abstract Although transparent radiative cooling is a passive strategy with practical applications and aesthetic appeal, complex manufacturing processes the use of environmentally unfriendly thermal emitters remain latent problems. Herein, eco‐friendly silk (TSRC) films are developed, regenerated from natural silkworm cocoons, for zero‐energy‐consumption management optoelectronic devices. These TSRC can dissipate heat radiatively through molecular vibrations protein backbone side chains,...
Surface-enhanced Raman spectroscopy (SERS)-based biosensors have attracted much attention for their label-free detection, ultrahigh sensitivity, and unique molecular fingerprinting. In this study, a wafer-scale, ultrasensitive, highly uniform, paper-based, portable SERS detection platform featuring abundant dense gold nanopearls with narrow gap distances, are prepared deposited directly onto ultralow-surface-energy fluorosilane-modified cellulose fibers through simple thermal evaporation by...
A polymer solar cell based on poly(3-hexylthiophene) (P3HT)/iron disulfide (FeS2) nanocrystal (NC) hybrid is presented.

An extended red light harvesting up 900 resulting from the device has been demonstrated, compared typical absorption edge 650 pristine P3HT. environmentally friendly and low-cost can be used as promising candidate for acceptor application enhanced photovoltaic response region.
In this study, we combine graphene with gold oxide (AuOx), a transparent and high-work-function electrode material, to achieve high-efficient, low-bias, large-area, flexible, transparent, broadband, bifacial-operable photodetector. The photodetector operates through hot electrons being generated in the charge separation occurring at AuOx-graphene heterojunction. large-area covering AuOx efficiently prevented reduction of its surface; it also acted as square-centimeter-scale active area for...
Abstract Solar‐induced thermal challenges in buildings, cold chain logistics, and spacecrafts may be overcome by integrating passive radiative cooling (PRC) with aerogels having insulation (TI). Herein, a universal silica aerogel (UCSA) is prepared through the simple regeneration freeze‐drying of commercial quartz fiber membranes. The optically engineered UCSA hybrid structure (silica nanofibers/microbeads) achieves remarkable solar reflectance ( R S.E. = 98.1%) atmospheric transparency...
Abstract In this study, the phenomenon of light trapping in Si solar cells coated with metal (Au) and dielectric (TiO 2 , SiO ) nanoparticles (NPs) is systematically investigated. contrast to previous reports, herein it proposed that photocurrent enhancement should be attributed limited antireflection ability Au NP arrays. other words, arrays might not enhance absorption active layer when no reflected from air–substrate interface. Therefore, NPs are replaced NPs, which possess lower...
Convenient, rapid, and accurate detection of chemical biomolecules would be a great benefit to medical, pharmaceutical, environmental sciences. Many biosensors based on metal nanoparticles (NPs) have been developed. However, as result the inconvenience complexity most current preparation techniques, surface plasmon-based test papers are not common as, for example, litmus paper, which finds daily use. In this we propose convenient practical technique, photothermal effect, fabricate plasmonic...
