Owing to its spatiotemporal selectivity and noninvasive nature, photodynamic therapy (PDT) has become a clinically promising approach for the treatment of a wide range of cancers and other diseases. However, the full potential of PDT has not been achieved thus far as a consequence of the lack of optimal photosensitizers (PSs) and/or smart transport/activation strategies. These problems, which unfortunately lie at the core of the PDT paradigm, include the oxygen reliance limits, the effect of PDT on hypoxic tumors, limitations of light penetration, and undesired skin photosensitization induced by "always on" PSs...

In this paper, we investigate the relationship between open-ring zones of the Fresnel zone plate and the pinhole rings of photon sieves (PSs). Numerical simulations show that the normalized diffraction fields near the focal point of an individual pinhole ring and the circular open-ring zone are the same. It is confirmed that the maximum diffraction efficiency of an open-ring zone is higher than that of the traditional pinhole ring. Meanwhile, pinhole rings have more flexibility for apodization filtering. Based on these key findings, we propose the design theory of an apodized diffractive optical element comprised of open-ring zones and pinholes...

The thermal stability of printed polymer solar cells at elevated temperatures needs to be improved to achieve high-throughput fabrication including annealing steps as well as long-term stability. During device processing, thermal annealing impact both the organic photoactive layer and the two interfacial layers making detailed studies of degradation mechanism delicate. A recently identified thermally stable PTB7:PC70BM blend as photoactive layer in combination with PEDOT:PSS as hole extraction layer is used here to focus on the impact of electron extraction layer (EEL) on the thermal stability of solar cells...

A real-time humidity sensor based on a microwave resonator coupled with a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) conducting polymer (CP) film is proposed in this paper. The resonator is patterned on a printed circuit board and is excited by electromagnetic field coupling. To enhance the sensitivity of the sensor, the CP film is located in the area with the strongest electric field in the resonator. To investigate the performance, the proposed sensor is placed alongside a reference sensor in a humidity chamber, and humidity is injected at room temperature...

Density functional theory (DFT) and time dependent DFT (TD-DFT) calculations were carried out for recently reported BODIPY-based photosensitizers (PSs) that can be activated by reactive oxygen species (ROS) to generate 1O2 specifically in target tissues. In order to assess the applicability of the compounds as activatable PSs (a-PSs) in photodynamic therapy (PDT), we investigated absorption wavelengths, singlet-triplet energy gaps and spin-orbit matrix elements for the radiationless transition, Sn→Tm. A TD-DFT qualitative analysis indicated that only a Br-substituted BODIPY derivative with chromanol ring of -tocopherol linked by methylene can work as an a-PS...

Hybrid organic photovoltaic (OPV) cells based on conjugated polymers photoactive materials are promising candidates for flexible, high-performance and low-cost energy sources owing to their inexpensive materials, cost-effective processing, and ease of fabrication by simple solution processes. However, the modest PV performance obtained to date -in particular the low power conversion efficiency (PCE)- has impeded the large scale deployment of OPV cells. The low PCE in OPV solar cells has been mainly attributed to low carrier mobility, which is closely correlated to the transport diffusion length of the charge carriers within the photoactive layers...

For PIN-type perovskite solar cells (PSCs), the hydroscopicity and acidity of PEDOT:PSS hole transport layer (HTL) perform critical influences on the device stability. To eliminate these problems, Nafion, the hydrophobic perfluorosulfonic-copolymer, is incorporated into PEDOT:PSS by simple spin-coating process. For the modified film, Nafion/PSSH acts as electron blocking layer on the surface and PEDOT-rich domain tends to gather into larger particles with better inter-chain charge transfer inside the film. Consequently, the modified-PEDOT:PSS HTL shows enhanced conductivity and light transmittance as well as more favorable work function, ending up with the increased short-circuit current density (Jsc) and open-circuit voltage (Voc) of device...

Numerous studies have reported that temporal order perception is biased in neurological patients with extinction and neglect. These individuals tend to perceive two objectively simultaneous stimuli as occurring asynchronously, with the ipsilesional item being perceived as appearing prior to the contralesional item. Likewise, they report that two stimuli occurred simultaneously in situations where the contralesional item is presented substantially prior to the ipsilesional item. Therefore, they exhibit a biased point of subjective simultaneity (PSS)...

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disorder with a complex pathophysiology primarily affecting exocrine glands, leading to compromised secretory function. Recent studies imply that many inflammatory mediators, such as pro-inflammatory cytokines and nitric oxide, are critical in the development and perpetuation of pSS systemic manifestations. In the current study, we aimed to investigate the ex vivo immunomodulatory effect of cardamonin (C16H14O4), on pro-inflammatory cytokines, TNF-α, IL-6 and inducible nitric oxide synthase (iNOS) expression during pSS...
