“…To overcome this problem, techniques to alter the surface characteristics without changing the bulk properties of the materials have been extensively investigated [1,2]. They include plasma treatment [3,4], corona discharge treatment [5,6], flame treatment [7,8] and exposure to highenergy radiation, such as gamma rays [9,10], electron and ion beams [11,12], and ultraviolet (UV) sources [13,14]. A variety of polar groups are introduced onto the polymer surface as a result of these treatments.…”

Surface modification of low‐density polyethylene (LDPE) and polytetrafluoroethylene (PTFE) films via graft copolymerization with acrylic acid (AAc), Na salt of styrenesulfonic acid (NaSS), N,N‐dimethylacrylamide (DMAA), 2‐(dimethylamino)ethyl methacrylate (DMAEMA), glycidyl methacrylate (GMA), acrylamide (AAm) and 3‐dimethyl(methacryloylethyl) ammonium propanesulfonate (DMAPS) was carried out for adhesion improvements. The surface microstructure and composition of the modified film surfaces were studied by angle‐resolved X‐ray photoelectron spectroscopy (XPS). It was demonstrated that the graft‐modified LDPE and PTFE films are capable of exhibiting adhesive‐free adhesion or auto‐adhesion. The GMA graft copolymerized PTFE surfaces adhere strongly to one another when brought into direct contact and cured (i) in the presence of an epoxy adhesive and (ii) in the presence of a diamine curing agent alone. It was further demonstrated that the ozone‐pretreated LDPE films and the Ar plasma pretreated PTFE films readily undergo photografting or thermal grafting with concurrent lamination when lapped together in the presence of a small quantity of the monomer solution. The simultaneous graft copolymerization and lamination process can be carried out under atmospheric conditions and in the complete absence of an added initiator or system degassing.

Tick-borne encephalitis in a 3-month-old child

et al. 1992

View full text Add to dashboard Cite

Tick-borne encephalitis has not been reported in infants younger than 12 months of age. We report a 3.5-month-old child with a serologically proven tick-borne encephalitis. The infant had a history of a tick bite 3.5 weeks before the first symptoms of encephalitis appeared. The family lives in an endemic area of the disease. There were no prodromal signs and the course of the disease was monophasic. In an endemic area, prophylactic treatment with hyperimmunoglobulin after a tick bite should be considered even in very young infants, but in most children active immunization is probably not necessary because of infrequent exposure. Active immunization is still recommended after the 1st year of life.

“…As an example, we show that when an index perturbation traverses a circular trajectory (Fig. 4a), photon pairs are emitted in a manner which bears some similarity to synchrotron radiation [53][54][55][56][57][58]. In a synchrotron, an electron is accelerated to near-light speeds along a kilometer-scale circular trajectory.…”

Sources of photons with controllable quantum properties such as entanglement and squeezing are desired for applications in quantum information, metrology, and sensing. However, fine-grained control over these properties is hard to achieve, especially for two-photon sources. Here, we propose a new mechanism for generating entangled and squeezed photon pairs using superluminal and/or accelerating modulations of the refractive index in a medium. By leveraging time-changing dielectric media, where quantum vacuum fluctuations of the electromagnetic field can be converted into photon pairs, we show that energy-and momentum-conservation in multi-mode systems give rise to frequency and angle correlations of photon pairs which are controlled by the trajectory of the index modulation. These radiation effects are two-photon analogues of Cherenkov and synchrotron radiation by moving charged particles such as free electrons. We find the particularly intriguing result that synchrotron-like radiation into photon pairs exhibits frequency correlations which can enable the realization of a heralded single photon frequency comb. We conclude with a general discussion of experimental viability, showing how solitons, ultrashort pulses, and nonlinear waveguides may enable pathways to realize this two-photon emission mechanism. For completeness, we discuss in the Supplementary Information how these effects, sensitive to the local density of photonic states, can be strongly enhanced using photonic nanostructures. As an example, we show that index modulations propagating near the surface of graphene produce entangled pairs of graphene plasmons with high efficiency, leading to additional experimental opportunities.
