TORTS-ALIENATION OF PARENT\u27S AFFECTION

Plaintiff, a minor child, brought a tort action against defendant for enticing her mother to desert her, thereby depriving plaintiff of support, maintenance, and maternal care and affection. The trial court sustained defendant\u27s demurrer. On appeal, held, affirmed. The statutes of the state provide other means of support of the child, and he has no right of action for the deprivation of a parent\u27s love and affection. Nelson v. Richwagen, (Mass. 1950) 95 N.E. (2d) 545

CORPORATIONS-DISSOLUTION-POWER OF CHANCELLOR TO DECREE DISSOLUTION WHEN DEADLOCK EXISTS

Plaintiffs sought dissolution of defendant corporation pursuant to a statute allowing a petition for dissolution to be made to the chancellor by the holders of one-half of the voting stock upon a deadlock in management and voting shares. The evidence showed that there was no chance of compromise by the warring factions, that the corporate function could not be carried out, and that the plaintiffs\u27 interests might be jeopardized. The chancellor held that unless a harmonious solution was effectively formulated within fifteen days after the filing of an opinion, a judgment containing appropriate provisions for a dissolution would be entered. On appeal, held, affirmed. The chancellor had the power to dissolve the corporation because sufficient equitable grounds besides deadlock were shown. RKO Theatres, Inc. v. Trenton-New Brunswick Theatres Co., (N.J. 1950) 74 A. (2d) 914

NEGLIGENCE-VIOLATION OF A DOG-LEASH ORDINANCE AS A BASIS FOR NEGLIGENCE

Defendant, in violation of a city ordinance requiring every owner or custodian of a dog to keep the animal on his own premises unless on a leash and under control of a competent person, allowed his dog to run loose on the street. On collision of the dog with plaintiff\u27s motor scooter, plaintiff brought suit for injuries incurred, claiming negligence per se by defendant through violation of the ordinance. The trial court sustained defendant\u27s demurrer. On appeal, held, reversed. The violation of the ordinance was negligence per se, since the purpose of the ordinance included the protection of people in traffic against the dangers that dogs may cause running loose. Brotemarkle v. Snyder, (Cal. App. 1950) 221 P. (2d) 992

Signal Stability in Periodically Amplified Fiber Transmission Systems Using Multiple Quantum Well Saturable Absorbers for Regeneration

The use of multiple quantum well (MQW) saturable absorbers (SAs) for signal regeneration in periodically amplified fiber transmission systems is explored. A systematic study of signal destabilization resulting from incomplete saturation of MQW SAs used for regeneration, and of means of overcoming such destabilization, is presented. A computer model for MQW SAs, which considers the asymmetric Fabry-Perot (AFP) cavity structure commonly employed to increase the contrast of such devices, is presented. The model is used to simulate nitrogen-implanted MQW SAs with 7000 km when the two components are combined.</p

Introducing MR‐TADF emitters into Light‐Emitting Electrochemical Cells for narrowband and efficient emission

The St Andrews authors thank the Engineering and Physical Sciences Research Council (EP/R035164/1).Organic semiconductors that emit by the process of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) can deliver narrowband and efficient electroluminescence while being processable from solvents and metal‐free. This renders them attractive for use as the emitter in sustainable light‐emitting electrochemical cells (LECs), but so far reports of narrowband and efficient MR‐TADF emission from LEC devices are absent. Here, this issue is addressed through careful and systematic material selection and device development. Specifically, the authors show that the detrimental aggregation tendency of an archetypal rigid and planar carbazole‐based MR‐TADF emitter can be inhibited by its dispersion into a compatible carbazole‐based blend host and an ionic‐liquid electrolyte, and it is further demonstrated that the tuning of this active material results in a desired balanced p‐ and n‐type electrochemical doping, a high solid‐state photoluminescence quantum yield of 91%, and singlet and triplet trapping on the MR‐TADF guest emitter. The introduction of this designed metal‐free active MR‐TADF material into a LEC, employing air‐stabile electrodes, results in bright blue electroluminescence of 500 cd m−2, which is delivered at a high external quantum efficiency of 3.8% and shows a narrow emission profile with a full‐width‐at‐half‐maximum of 31 nm.Publisher PDFPeer reviewe
