Rapid, accurate, and safe screening of foodborne pathogenic bacteria is essential to effectively control prevent outbreaks illness. Fluorescent sensors constructed from carbon dots (CDs) nanomaterial-based quenchers have provided an innovative method for bacteria. Herein, ultrasensitive magnetic fluorescence aptasensor was designed separation detection Staphylococcus aureus (S. aureus). Multicolor fluorescent CDs with a long lifetime (6.73 ns) high stability were synthesized using facile...
The review describes general principles and characteristics of inhomogeneously polarized paraxial optical fields and, especially, the polarization singularities (PSs). Main parameters vector waves are discussed, with emphasis on physical relevance topological distinctiveness PSs. Special features stochastic considered in context PSs’ genericity structural stability. A detailed attention is paid to interrelations between PSs phase scalar formed by orthogonal projections total field, their...
A new type of bismuth doped Ba(2)B(5)O(9)Cl crystal is reported to exhibit broadband near infrared (NIR) photoluminescence at room temperature, which has been identified here originating from elementary atom. Rietveld refining, static and dynamic spectroscopic properties reveal two types Bi(0) centers in the compound due successful substitution for different nine-coordinated barium lattice sites. These can be created only a reducing condition, when treated air N(2)/H(2) flow turn, they...
A method to generate orbital angular momentum (OAM) radio waves based on dielectric resonator antenna is demonstrated. An equivalent model built investigate this OAM in detail. Simulation and measurement are also carried out for antenna. Both simulated results show typical efficient radiation of OAM-carrying waves. It can with different mode numbers at frequencies. Because its compact structure, low cost, small size, will be a cost-effective solution wave generation.
A novel polymer architecture design for GPEs is proposed via in situ copolymerization of VC and a new acylamino-crosslinker. This enables accelerated Li + transport dual-reinforced stable interfaces, contributing to long-lifespan LMBs.
Fronthaul plays a crucial role in bridging mobile and optical communications. Conventional digital radio-over-fiber (RoF) systems, utilizing the common public radio interface (CPRI), require capacity exceeding an order of magnitude above user data rate, posing challenges for dense small cell deployments growing bandwidth demands 6 G beyond. Intermediate-frequency-over-fiber (IFoF) with intensity modulation direct detection (IM/DD) presents promising alternative due to its high spectral...
CD58 and CD2 have long been known as a pair of reciprocal adhesion molecules involved in the immune modulations CD8+ T NK-mediated cellular immunity humans several other mammals. However, functional roles CD4+ T-mediated adaptive humoral remain poorly defined. Moreover, current observations were mainly acquired from vitro assays, vivo investigation is greatly limited due to absence Cd58 homology murine models. In present study, we identified cd58 cd2 homologs model species zebrafish (Danio...
For phosphor‐converted warm white light‐emitting diodes ( WLED s), it is essential to find highly efficient red oxide phosphors, which are better chemically stable and benign environment can be prepared in a much milder condition. Here, we report phosphor LiNaGe 4 O 9 :Mn 4+ with quantum yield up 78% after systematic optimization synthesis temperature, dopant concentration of Mn , sintering time. Best performance the reached when synthesized mild reaction condition, that is, at 850°C for 3 h...
Bismuth-doped glasses have received much attention in the last decade due to their broadband near-infrared (NIR) emission. Their optical properties are sensitive composition and there a few reports that qualitatively describe dependence of these on compositions. Yet actual role bismuth, as matrix changes, remains fundamentally unclear. In this work, we investigate bismuth-doped germanate with different compositions interpret dependences terms microscopic structure using Raman Fourier...
The nature of bismuth NIR luminescence is essential to develop the doped laser materials with high efficiency and desirable emission wavelength, it, thereby, receives rising interests. Our previous work reported Bi(0) from Ba2B5O9Cl: Bi a lifetime ~30 μs conversion Bi(2+) Bi(0). This found indeed could be enabled in compound by an situ reduction technique however, happens via intermediate state Bi(+). Once ion Bi(+) stabilized built into compound, it can luminesce super broad spectral range...
The electromagnetic beam carrying orbital angular momentum (OAM) has a twisted phase front, which can induce rotational Doppler frequency shift when it is illuminating on spinning object. In this paper, the effect induced by radio wave OAM theoretically analyzed and experimentally verified. Compared with an optical vortex beam, divergence angle of typically larger than that results in OAM-based sensing system short-range detection distance. case, receiver's location deflection rotating plane...

The applications of orbital angular momentum (OAM) carried beam are limited by its on-axis phase singularity and wide-angle directivity. In this paper, a new form OAM wave termed as plane spiral is proposed. Different from general propagating along the axial direction, has distinguishing characteristic transverse propagation. Hence it no propagation path divergence problem longer exists. A traveling-wave circular slot antenna excited 90° hybrid coupler used to generate waves. Due ring horn...
