Abstract Cancer immunotherapy has received tremendous attention in the past decade owing to its clinical successes with the use of immune‐checkpoint inhibition and chimeric antigen receptor T cell therapy. However, only a small proportion of the patients have benefited from these immunotherapeutic drugs, which has rai…
High Resolution Image Download MS PowerPoint Slide Solar cells based on metal halide perovskites often show excellent efficiency but poor stability. This degradation of perovskite devices has been associated with the migration of mobile ions. MAPbBr 3 perovskite materials are significantly more stable under ambient co…
Abstract Organic–inorganic hybrid perovskites have attracted considerable attention due to their superior optoelectronic properties. Traditional one‐step solution‐processed perovskites often suffer from defects‐induced nonradiative recombination, which significantly hinders the improvement of device performance. Herei…
). Our results demonstrate that metal-doped layered materials, such as TMDs, constitute an emergent platform to construct ultrasensitive and tunable biosensors.
Brain-inspired parallel computing, which is typically performed using a hardware neural-network platform consisting of numerous artificial synapses, is a promising technology for effectively handling large amounts of informational data. However, the reported nonlinear and asymmetric conductance-update characteristics…
Ammonia is one of the most important feedstocks for the production of fertilizer and as a potential energy carrier. Nitride compounds such as LaN have recently attracted considerable attention due to their nitrogen vacancy sites that can activate N 2 for ammonia synthesis. Here, we propose a general rule for the desig…
We mapped the metal sequences within crystals of metal-oxide rods in multivariate metal-organic framework-74 containing mixed combinations of cobalt (Co), cadmium (Cd), lead (Pb), and manganese (Mn). Atom probe tomography of these crystals revealed the presence of heterogeneous spatial sequences of metal ions that we…
A major challenge for organic solar cell (OSC) research is how to minimize the tradeoff between voltage loss and charge generation. In early 2019, we reported a non-fullerene acceptor (named Y6) that can simultaneously achieve high external quantum efficiency and low voltage loss for OSC. Here, we use a combination of…
Fluorescence imaging has become a fundamental tool for biomedical applications; nevertheless, its intravital imaging capacity in the conventional wavelength range (400-950 nm) has been restricted by its extremely limited tissue penetration. To tackle this challenge, a novel imaging approach using the fluorescence in t…
Nanoparticles of enzyme Nitrate reductase (NaR) a soluble homodimer enzyme of ∼100 kDa polypeptide with cofactors – FAD, heme-molybdopterin (Mo-MPT) and electron donor NAD(P)H, catalyses the reduction of nitrate to nitrite has been synthesised. Nanoparticles of Nitrate reductase enzyme have been prepared by chemical d…
IR-Fourier spectroscopy was used to study structural changes in γ-irradiated high density polyethylene composites with GaAs and GaAs semiconductor fillers at room temperature. From the dose dependence of the crystallinity degree of the HDPE/GaAs and HDPE/GaAs composites, it was found that the HDPE/GaAs composites are…
Although stimuli-responsive release systems have attracted great attention in medical applications, there has been no attempt at "precise" deep profile control based on such systems, which is greatly need to improve oil recovery. With this in mind, we provided a facile and simple strategy to prepare stimuli-responsive…
Multifunctional multiferroic materials, such as rare-earth-doped yttrium iron garnet (YIG), are advantageous for low-energyconsumption devices. In this work, we investigated aliovalent (Ce4+) substitution in Y2.9Bi0.1Fe5O12ferrite with different compositions Y2.9-xCexBi0.1Fe5O12(x = 0.0, 0.2, 0.4), respectively. The f…
Tungsten carbide (WC) nanostructures were prepared by carbothermal reduction (CR) of tungsten-impregnated pinewood-derived activated carbon (AC) at 1000 °C under an inert atmosphere. Brunauer-Emmet-Teller (BET) surface area, pore structures of the AC, and catalyst samples were evaluated by N2 adsorption-desorption exp…
Diffraction optical elements (DOE) are important elements of systems for images displaying and processing. The DOE materials with both positive and negative birefringence enhance performances and functionality of such systems. We have calculated the diffraction of rays passing through optically anisotropic grating wit…
Magnesium (Mg) based implants such as plates and screws are often preferred to treat bone defects because of the positive effects of magnesium in bone growth and healing. Their low corrosion resistance, however, leads to fast degradation and consequently failure before healing was completed. Previously, we developed M…
Bi2Fe4O9(BFO) nanocubes have been prepared in proportion by a simple and easy hydrothermal method, and then the BFO nanocubes were assembled on the reduced graphene oxide (rGO) multilayered sheets. The excellent microwave absorption properties of Bi2Fe4O9/rGO nanohybrids were achieved by properly adjusting impedance m…
The China Fusion Engineering Test Reactor (CFETR) tritium plant has to deal with a larger amount of tritium than ITER. The tritium source term is one of the key issues for safety assessment and operation of the CFETR. In this technical note, the preliminary estimation and safety analysis of the tritium source term for…
Results of UV-vis spectroscopy (spectrophotometry) of highly conductive submicrometer nitrogen-incorporated ultrananocrystalline diamond, (N)UNCD, processed in technologically important oxygen and hydrogen plasmas are presented for the spectral range of 200–1200 nm. The (N)UNCD films feature high contrast interference…
Tungsten samples have been irradiated with 3 MeV protons with dose rates of 1×10-04 to 5×10-05 dpa/s to doses of 0.01–0.67 dpa at 360 K in a pilot experiment. Micro- and macro-indentation were used to measure irradiation hardening in the samples. An initial irradiation hardening of 1.23 ± 0.09 GPa and 1.88 ± 0.83 GPa…
