Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

Advanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Electric‐Field‐Assisted Spin Coating: A New Process for Adjusting Crystallization of Perovskite Thin Films

Advanced Materials Technologies, EarlyView.
Electric‐field‐assisted spin coating is introduced as a wet‐film processing route for guiding perovskite crystallization. A transient perpendicular field produces distinct structural maxima rather than monotonic grain growth: largest scanning electron microscopy (SEM)‐derived grain size at nominal 2 kV cm−1${\rm cm}^{-1}$, largest X‐ray diffraction ...

Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

Advanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Cross-contamination in dishwashers

Journal of Hospital Infection, 2004
Dishwashers are used in central hospital kitchens and ward kitchens to provide clean crockery. Soil recipes based on international standards were tested in order to evaluate the performance of a general dishwasher. In normal use of dishwashers, adherent soils are left on the crockery before cleaning.

Cross-Contamination Potential With Dental Equipment

Lancet, The, 1992
Some types of reused dental equipment, especially handpieces and their attachments for drilling and cleaning teeth, might be responsible for cross-contamination if patient material were to lodge temporarily in difficult-to-disinfect internal mechanisms. This possibility is worrisome with respect to transmission of hepatitis B and human immunodeficiency

Control of Cross-Contamination

The Journal of the American Dental Association, 1972
High-speed, air-driven handpieces and dental burs are contaminated after use and thus they can be a source of cross-contamination of patients. The effectiveness of the disinfectant solutions of benzalkonium chloride and aqueous activated 2% glutaraldehyde was compared in tests involving suspensions of two microorganisms. The glutaraldehyde solution was

Avoiding cross-contamination in prosthodontics

The Journal of Prosthetic Dentistry, 1981
Reduction of the potential for cross-contamination in prosthodontics may be accomplished in the following ways: 1. Use surface covers such as clear plastic wraps or bags over instruments like face-bow, articulators, and torch handles. 2. Disinfect surfaces with chemical agents such as 1% iodine surgical scrub in 70% isopropyl alcohol in a ratio of 1:2 ...

Cross-Contamination of Cells in Culture

Science, 1981
Lists are presented of references to all known publications describing cell properties that serve to characterize (i) known strains of HeLa and purported human cell lines indicted as HeLa contaminants, (ii) strains of human cell lines contaminated with human but non-HeLa cells, and (iii) strains of cells contaminated by cells from one or more other ...
