Disclosed embodiments include illustrative piezoelectric element array assemblies, methods of fabricating a piezoelectric element array assembly, and systems and methods for shearing cellular material. Given by way of non-limiting example, an illustrative piezoelectric element array assembly includes at least one piezoelectric element configured to produce ultrasound energy responsive to amplified driving pulses. A lens layer is bonded to the at least one piezoelectric element. The lens layer has a plurality of lenses formed therein that are configured to focus ultrasound energy created by single ones of the at least one piezoelectric element into a plurality of wells of a microplate disposable in ultrasonic communication with the lens layer, wherein more than one of the plurality of lenses overlie single ones of the at least one piezoelectric element.

A cryostat chuck is disclosed. The disclosed chuck may be configured for use in a frozen-sectioning device, such as a cryostat, or other suitable host equipment. The disclosed chuck may include a tab portion configured, in accordance with some embodiments, to provide a means for gripping the chuck by hand (e.g., human or robotic) or by a tool or other desired interfacing element. The tab portion may serve to distance a user's hand or piece of gripping equipment from the sharp microtome of the host cryostat, reducing the opportunity of sustaining bodily injury or equipment damage. Moreover, the tab portion may provide a means by which the cryostat chuck may be manipulated when inserting, adjusting, or removing the chuck prior to, during, or after engagement by the cryostat (or other suitable host equipment).

A system and method for preparing a sample area of a bale in order to more accurately evaluate the plant material incorporated into the bale. A baler receives, compresses, shapes, and secures material into the bale. A cutter mechanism cuts a portion of the material in the bale into similarly-sized particles. A mixer mechanism mixes the particles into a homogenous aggregate. A compression mechanism compresses the homogenous aggregate into the bale. An NIR testing system receives and analyzes near-infrared radiation reflected by the homogenous aggregate, and generates evaluation data reflecting properties of the material. The cutter may include knives mounted in a compression chamber of the baler. The mixer may be a relief feature on a center rail, the compressor may be a projecting feature on the center rail, and an NIR sensor may be mounted to the center rail so as to press against the surface of the bale.

A semiconductor analysis system includes a machining device that machines a semiconductor wafer to prepare a thin film sample for observation, a transmission electron microscope device that acquires a transmission electron microscope image of the thin film sample, and a host control device that controls the machining device and the transmission electron microscope device. The host control device evaluates the thin film sample based on the transmission electron microscope image, updates acquisition conditions of the transmission electron microscope image based on an evaluation result of the thin film sample, and outputs the updated acquisition conditions to the transmission electron microscope device

A lamella 10 including an analysis portion 11 and a cutout portion 12 separated from the analysis portion 11 is produced. When a plurality of the lamellae 10 are transported to a lamella grid 20, the plurality of lamellae 10 are supported by a support portion 22 protruding from a surface of a substrate 21, and are mounted adjacent to each other in a Z direction. At this time, the cutout portion 12 prevents the analysis portion 11 from damage.

A synthetic source rock including roasted tea powder and inorganic material. A technique for preparing the synthetic source rock, including grinding tea leaves to give tea powder, roasting the tea powder at a roasting temperature to give a roasted tea powder, and determining composition and porosity of the roasted tea powder.

A testing method of thermal barrier coating (TBC) is for evaluating the presence or absence of damage to TBC formed on a bending part on which compression stress acts. The method includes a test piece that includes a pair of arm parts, a bending part arranged between the pair of arm parts, and a TBC layer on a bending surface of the bending part; attaching the test piece to a compression testing device after preparing the test piece; and applying compression stress to the test piece in a direction for bringing the pair of arm parts close together after attaching the test piece with the compression testing device. The pair of arm parts are arranged so as to separate from each other from base end portions toward front end portions of the arm parts. The bending part is arranged between the base end portions.
