Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

open access: yesAdvanced Functional Materials, EarlyView.
A bio‐inspired biopolymeric implantable drug delivery platform enables localized and sustained release of 7‐ethyl‐10‐hydroxycamptothecin (SN‐38) in solid tumor treatment. The three‐dimensional (3D) structured crosslinked‐chitosan implants are fabricated via 3D‐printed molds and provide drug release over 3 months, significantly inhibiting tumor growth ...

Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

open access: yesAdvanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...

1.4.2 Laboratory and mass rearing

1997
Publisher Summary This chapter discusses coccid rearing methodologies and procedures inherent in the introduction and subsequent culture or mass rearing of natural enemies. Ideally, the scale insect species selected for culture would include: (1) the target species, (2) the original host of the imported parasites, and (3) some readily cultured ...

Ecology of Rearing: Quality, Regulation, and Mass Rearing

2019
A 1992 list of biological control agents sold commercially in North America listed 105 species of arthropods to control arthropods and 27 species of arthropods to control weeds. This chapter describes some of the goals and constraints of commercial mass production of arthropods, how those goals may conflict with requirements of biological control ...

Quality Control of Mass Reared Egg Parasitoids

2009
In this chapter we will present methods for determination of the quality of mass reared egg parasitoids. Before we describe quality control guidelines, we will first outline the development of quality control of natural enemies, summarize the basic considerations concerning management of laboratory populations, and discuss obstacles in mass rearing ...

Quality Aspects of Mass-Reared Insects

1977
Control of the quality of mass-produced industrial goods is a matter of survival for any industrial enterprise that has to compete on the market. A constant survey of the market situation provides feedback to the factory where quality, design, or price levels have to be adjusted in order for the company to remain in business.

Behavioral aspects of mass-rearing of insects

Entomophaga, 1972
The present situation and objectives of mass rearing insects are reviewed under the aspect of behavior. The highest degree of “typical” behavior is required in those species that have to compete with their natural counterparts in the field. Selection pressure and conditioning during the process of mass rearing might alter the behavior of the organisms ...

Mass Rearing of Barnacle Cyprids in the Laboratory

Nature, 1960
INTEREST in laboratory experiments on ships' fouling organisms is increasing, yet attempts to rear barnacle larvae to cyprid stage have generally met with only limited success1–6. It therefore seems appropriate to place on record a reliable rearing method, which has been developed here to provide material in connexion with experiments on the use of ...
