INFORMATION
Oct 5 2018 [ Attention/注意] Typhoon is approaching/台風が来ています。
To all University staff and students,
On the heels of deadly Typhoon Trami, Typhoon Kong-rey (Typhoon Number
25) is forecast to reach northern Japan on Sunday, October 7
with keeping the wind speed of 25 meters per second (56mph) and continue
towards the east coast of Hokkaido.
MET Office (Japan Meteorological Agency) gives alert against violent
winds, high waves and heavy rainfall.
We may see Typhoon Kong-rey bring damage to our local environment, such as:
-Damage or collapse of buildings/structural objects;
-Accidents/injuries caused by fallen trees, branches or blown-off
objects due to high winds;
-Flood in heavy rains or by tidal waves; and
-Landslide disasters.
Stay alert to weather conditions and warnings, and pay attention to the
safety of students and staff in your lab/section.
In case of injuries or property damage, take appropriate actions and
contact General Affairs Division, General Affairs and Planning Department.

Sept 29 2018 [ Attention/注意] Typhoon is approaching/台風が来ています。
Hokkaido University gives us following caution.
To all University staff and students,
Super Typhoon Trami (Typhoon Number 24) is moving over the waters
southeast of Miyako Island as of 12 PM today,
approaching the islands of Okinawa and Amami with highest sustained winds.
It is forecast to pick up speed and move across eastern and northern
Japan on Monday next week.
MET Office (Japan Meteorological Agency) gives alert against violent
winds, high waves and heavy rainfall.
We may see Typhoon Trami bring extended damage to our local environment,
such as:
-Damage or collapse of buildings/structural objects;
-Accidents/injuries caused by fallen trees, branches or blown-off
objects due to high winds;
-Flood in heavy rains or by tidal waves; and
-Landslide disasters.

Title :
Phosphorous Diffusion Through Ni2P—Low Energy Diffusion Path and Its Unique Local Structure(
J. Phys. Chem. C, Article ASAP )
DOI: 10.1021/acs.jpcc.7b12367

Abstract
ABSTRACT: Phosphorous (P) diffusion in bulk Ni2P was
investigated by the density functional theory (DFT) to find the
origin of the low-temperature P diffusion into the surface. The Ni2P
bulk structure consists of two types of layers, Ni3P2 and Ni3P1,
stacked along the [0001] direction. Two types of P vacancies in Ni2P
were studied: V1P (P deficient in N3P2) and V2P (P deficient in N3P1).
V1P was a slightly more stable point defect than V2P by 0.20 eV. The P
diffusions to vacancies (V1P and V2P) had large diffusion barriers of
more than 1 eV, except the P diffusion path along the [0001]
direction through an interstitial site in Ni3P1 (I1→2 P ) and then to V1P,
which showed the lowest energy barrier of about 0.18 eV. The DFT
calculations suggested that the two adjacent vacancies (both V1P)
allow the local rearrangement of the structure to form a tetrahedral
structure at the intermediate state. We have proposed a new diffusion
mechanism in the intermetallic compound named the interstitial−vacancy diffusion mechanism.
