Small and hard seeds: a practical and inexpensive method to improve embedding techniques for light microscopy

open access: yesActa Botânica Brasílica, 2014
The traditional techniques employed for embedding plant samples are not suitable for the proper processing of small seeds with hard seed coats. Usually, these seeds are broken off from blocks during microtomy, which limits the technical success of this ...

The morphology and topography of polymer surfaces and interfaces exposed by ultra-low-angle microtomy [PDF]

open access: yes, 2017
The ultra-low-angle microtomy (ULAM) technique has been developed to impart a cross-sectional, ultra-low-angle taper through polymeric materials such as coatings and paints. ULAM employs a conventional rotary microtome in combination with high-precision,

A ToF-SIMS investigation of a buried polymer/polymer interface exposed by ultra-low-angle microtomy [PDF]

open access: yes, 2004
The interfacial region of a model, multilayer coating system on an aluminium substrate has been investigated by high resolution time-of-flight secondary ion mass spectrometry (ToF-SIMS). Employing ultra-low-angle microtomy (ULAM), the interface between a

Construção de um micrótomo de congelamento a partir da adaptação de um micrótomo de parafina

open access: yesBrazilian Archives of Biology and Technology, 1998
A microtome for frozen sections was developed using the facilities and equipment available in our country. The requirements for making it were: 1) fast frozen of the tissue, 2) easy histological procedure, 3) no necessity of long period for preparation ...

Spontaneous Long‐Range Order and Alignment in Phase‐Separated Dynamic Covalent Networks Using Discrete Siloxanes

open access: yesAngewandte Chemie International Edition, EarlyView.
Spontaneously aligned, long‐range hexagonal columnar ordering is obtained in phase‐separated dynamic covalent networks by combining discrete siloxanes and dynamic acylsemicarbazide bonds. The ordered network shows improved (thermo)mechanical properties and creep resistance compared to the disordered network.

Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Methylmercury intoxication and histochemical demonstration of NADPH-diaphorase activity in the striate cortex of adult cats

open access: yesBrazilian Journal of Medical and Biological Research, 1998
The effects of methylmercury (MeHg) on histochemical demonstration of the NADPH-diaphorase (NADPH-d) activity in the striate cortex were studied in 4 adult cats. Two animals were used as control.
