By first-principles calculations, for Heusler alloys Pd2CrZ (Z = Al, Ga, In, Tl, Si, Sn, P, As, Sb, Bi, Se, Te, Zn), the effect of Zn doping on their phase transition and electronic structure has been studied in this work.

A one-step hydrothermal approach for synthesizing BiOCl–phosphotungstic acid (BiOCl–HPW) heterojunctions is proposed. The prepared BiOCl–HPW heterojunction exhibited good stability and photocatalytic activity.

2e and 2j with strong p-NO2 and p-CF3 at phenyl ring had the lowest MICs against S. aureus and MRSA. 2e displayed unaided or synergistic efficacy against MRSA, especially combined with ofloxacin. EM revealed that 2e destroys biofilms and cell membranes.

Ladybird macro photographs

This morning hundreds of ladybirds were flying through the air and massing on the white walls of the house. I managed to get a few clear macro photographs.

The sun was shining and the ladybirds seemed to be attracted to anything white. I stuck a white T-shirt on and headed outside. Pretty soon I was covered in them and could pluck them from my shirt to get some close ups using my little Canon IXUS 60.

At some point a ladybird took off just before I tried to photograph it and I decided I’d try to capture that moment. A few minutes later I’d worked out that I could prompt one of the insects to walk up my finger like the stem of a flower, that they’d take off when they reached the tip, and that they took up a distinct posture just before their wing-case shot open.

The speed at which they prepare to take off, open their wings, and fly away is so quick that I just had to take the shot as soon as I saw a ladybird get into the “take-off position” and hope that I reacted fast enough to get a picture of the open wing-case.

CSS typography experiment

This is a quick experiment that reproduces an image from I Love Typography using semantic HTML, CSS 2.1, a little CSS3. Along the way, I learnt about a few modern browser bugs and inconsistencies.

I came across an image on I Love Typography that I thought could be reproduced using only semantic HTML and CSS.

A scaled down and cropped version of the I Love Typography A Lot image from I Love Typography.

The idea was to reproduce the image from simple markup, and to rely as much as possible on what can be achieved with CSS.

This is the HTML I ended up using.

<p>I love <strong>typography</strong> <em>a lot</em></p>

This is the CSS that controls the presentation of that content.

body {
  padding: 0;
  margin: 0;
  font-family: Times New Roman, serif;
  background: #000;
}

p {
  position: relative;
  width: 1100px;
  padding: 100px 0 0;
  margin: 0 auto;
  font-size: 175px;
  font-weight: bold;
  line-height: 1.2;
  letter-spacing: -13px;
  color: #0caac7;
  transform: rotate(-20deg);
}

/* "i" */
p:first-letter {
  float: left;
  margin: -137px -20px 0 0;
  font-size: 880px;
  line-height: 595px;
  text-transform: lowercase;
}

/* "love" */
p:first-line {
  font-size: 200px;
}

/* "typography" */
p strong {
  display: block;
  margin: -80px 0 0;
  font-weight: normal;
  letter-spacing: -2px;
  text-transform: capitalize;
}

p strong:first-letter {
  margin-right: -30px;
  color: #fff;
}

/* "a lot" */
p em {
  position: absolute;
  z-index: 10;
  top: 100px;
  left: 147px;
  width: 136px;
  overflow: hidden;
  padding-left: 64px;
  font-size: 200px;
  font-style: normal;
  text-transform: lowercase;
  color: #fff;
}

p em:first-letter {
  float: left;
  margin: 130px 0 0 -55px;
  font-size: 80px;
  font-style: italic;
  line-height: 20px;
  color: #fff;
}

/* create the heart shape */
p:before,
p:after {
  content: "";
  position: absolute;
  z-index: 1;
  top: 225px;
  left: 120px;
  width: 75px;
  height: 50px;
  background: #000;
  transform: rotate(45deg);
  border-radius: 25px 0 0 30px;
}

p:after {
  left: 138px;
  transform: rotate(-45deg);
  border-radius: 0 25px 30px 0;
}

/* hide the tip of the "t" from "a lot" */
p strong:before {
  content: "";
  position: absolute;
  z-index: 11;
  top: 205px;
  left: 341px;
  width: 7px;
  height: 7px;
  background: #000;
  border-radius: 7px;
}

The final CSS typography experiment approximates the original image in all modern browsers that support the CSS3 properties of border-radius and transform.

Some browsers render type (especially after rotational transformations) better than others. Note that all the screenshots are taken from browsers running on Windows Vista OS.

Opera 10.5. The closest approximation to the original source image.
Chrome 4.0. Identical to Opera 10.5 apart from a bug that appears in the rendering of rounded corners when they undergo a rotational transformation.
Safari 4.0. The rotated type suffers from a lack of anti-aliasing.
Firefox 3.6. The rotated type suffers from a lack of anti-aliasing.

Browser bugs and inconsistencies

I’ve put together a small test page to highlight some new CSS 2.1 and CSS3 bugs in modern browsers. It includes two new CSS 2.1 bugs in Internet Explorer 8.
