The effects of annealing on phase transformation in platinum-molybdenum coatings [PDF]

, 2012
Includes bibliographical references.The thermodynamic study of platinum binary systems has both fundamental and applied aspects. It is due to the fact that the formation of ordered phases increases the strength and surface hardness and could also have an

Chemical and isotopic composition of Os-rich allois and sulfides from the Evander Goldfield of the Witwatersrand Basin (South Africa)

Литосфера, 2016
We firstly report compositional and isotope-geochemical characteristics of Ru-Os-Ir(-Pt) alloys, Ru-Os sulfides and polycomponent solid solutions of the system Ru-Os-Ir-Pt (±Fe) derived from the Kimberley Reef within Evander Goldfield of the ...

Bacterial preoxidation of Stillwater Complex, MT, platinum-group metal flotation concentrate and recovery of plantinum-group metals by cyanidation and other leachants [PDF]

"In research conducted by the U.S. Bureau of Mines, platinum-group metal (PGM) flotation concentrate from the Stillwater Complex, MT, was subjected to biooxidation using thiobacillus ferrooxidans in an effort to break down the sulfide minerals and ...

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

The Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Optimized micro‐sized cell sphere‐matrix niche co‐aggregates promote efficient oral and craniomaxillofacial bone regeneration

BMEMat, EarlyView.
The construct of cell‐niche co‐aggregates (GelMA‐SHED sphere‐DDMPs) promotes cranial and periodontal bone regeneration and ensures angiogenic‐osteogenic coupling by downregulating miR‐34c‐5p to enhance the expression of NOTCH1 and its intracellular domain (NICD).

A biomechanical optimized Zr58Cu25Al14Nb3 bulk metallic glass dental implant improves peri‐implant stress distribution and bone quality under physiological loading

BMEMat, EarlyView.
This study reports a novel Zr58Cu25Al14Nb3 bulk metallic glass that possesses high mechanical strength and low elastic modulus, which further promotes efficient mechanotransduction and significantly improves peri‐implant bone quality upon cyclic occlusal loading.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.
